Lynn Settles With Cisco, Investigated By FBI

Following up on yesterday's story, daria42 writes "Security researcher Michael Lynn has settled a dispute with Cisco over his presentation on hacking the company's routers, which was given at the Black Hat security conference in Las Vegas this week. The two parties and Black Hat organisers have agreed not to further discuss the presentation, which contained techniques Lynn said could bring the Internet to its knees." Not all is good news, though. jzeejunk writes "The FBI is investigating computer security researcher Michael Lynn for criminal conduct after he revealed that critical routers supporting the internet and many networks have a serious software flaw that could allow someone to crash or take control of them."

No good deed goes unpunished.

What a load of horseshit. Lynn follows his conscience and speaks up about Cisco's security vulnerabilities, and not only is he severely slapped down by this permanent injunction (which I don't consider 'good news' in any sense), but now the FBI has decided to get involved. It'll be chilling to watch them pull his life apart and examine each bit under a microscope over months or years.

Lynn exposed a serious security flaw that could have been used to compromise networks throughout the nation. Cisco should be rewarding him for protecting them against losses they would no doubt have experienced in the future if this flaw went unreported. As for the government, they should be pinning a medal on Lynn, not investigating him.

Re:No good deed goes unpunished.

[Stevix]

the issue is also about how he reported the flaw, not just tha he did. Cisco has its own vunerability submission protocols in house, be he instead showed his findings at a Black Hat conference instead, exposing it to any savvy hacker willing to act on them.

We forget that if the Bush administration has taught us anything, it's that secret is better. The FBI will investigate any leaking of information, because information is not to be shared with the masses. God forbid. I am TOTALLY reporting your ass to the thought police.

Re:No good deed goes unpunished.

[daveschroeder]

Actually, the FBI has not "decided" to get involved. Lynn's own lawyer says she believes the FBI is merely following up on a complaint that it received from either Cisco or ISS before the settlement was reached. In other words, Cisco or ISS may have been (inappropriately or not, depending on your stand on trade secrets) attempting to silence Lynn, but the FBI wasn't just doing this on its own. Is the FBI not supposed to investigate allegations of crime? The FBI doesn't even know whether a crime has been committed.

Further, Lynn himself admitted that the vulnerability had already been patched by a Cisco update. Lynn's issue is that he didn't believe Cisco presented the vulnerability (or its patch) in an urgent enough fashion.

And "the government" isn't doing anything save for investigating an allegation of a crime, as it is charged with doing when it receives a complaint. Should the police no longer respond when 911 is dialed unless it's absolutely certain a crime is being committed? Is this not what "investigation" is for? Sorry, I don't buy into the conspiracies.

Yes, and this is exactly why the FBI should get involved! The army has stringent oversight procedures for this sort of thing, and to reveal flaws in top-secret installations without even going up the chain of command is tantamount to treason!

Oh wait. The dude isn't in the army. Or in government. Actually, his former employer settled the case. So the overriding federal government interest in this is...? Why, you might be forgiven to think "nothing at all, in fact, this sort of thing is precisely why such liberties as freedom of the press exist; even though this is a lone individual, surely some type of whistle-blower protection would exist that covers this, otherwise the public would never be made aware of critical flaws in the nation's privately-owned infrastructur until it was too late!"

But apparently, you'd be wrong. You see, by merely mentioning, without even going in to much specifics, that it might be possible for some-one else to exploit a flaw in Cisco's equipment, this guy has clearly commited a thought-crime. That's because warning people about security flaws is exactly the same as instructing people in cyberwarfare, and issueing commands to them to act on your behalve to bring down Western Civilization as we know it. You see, no difference there at all.

Of course, this is also why trains never run on time. If the published time tables were accurate, the railways would get prosecuted by the FBI for inviting people to commit suicide by throwing themselves in front of the 18:02 train.. Bet you didn't know that!

Re:No good deed goes unpunished.

[James_Aguilar]

Well, first of all, it's not "undoubted" that Cisco would have experienced losses if the flaw had gone unreported. According to them, they were busy fixing it, and though I know we hate to listen to the big evil corporations, there is the slightest possibility that they weren't lying.

Second, it's Cisco's right to do what they want with his research, since he did *break the law* in order to release it ( decompiling code + license agreement -> ?=( ). Following your conscience (in a way that was by some reports rash and poorly thought out) does not necessarily give you immunity from the consequences of your action.

As a security researcher, he of all people, should know the high stakes in that game. It's not like either Cisco's or the FBI's actions couldn't have been anticipated by anyone who thought the whole thing through to its logical conclusion. Hopefully, he had prepared himself for the inevitable results of his actions before he took them. Otherwise, I feel really bad for him.

Re:No good deed goes unpunished.

[Clockwurk]

Cisco should be rewarding him for protecting them against losses they would no doubt have experienced in the future if this flaw went unreported.

If the project is open source, there should be a push to have the flaw (and technical details) examined by the largest number of eyes possible (so that they can develop fixes).

If the software is closed source, the only person that can fix the flaw is the vendor and giving presentations to a bunch of hackers about exploiting the vulnerability doesn't seem very responsible.

Re:No good deed goes unpunished.

[cpeikert]

Further, Lynn himself admitted that the vulnerability had already been patched by a Cisco update.

One specific buffer overflow vulnerability was patched. But Lynn's presentation was a general approach to exploit any buffer overflow, with dire consequences. There is likely more exploitable code inside those routers; it's just a matter of time before some is found. At that point Lynn's attack could be executed.

Nice strawman, but that of course isn't what the (predictably modded-down) parent said.

All he's saying is that you shouldn't be surprised when the FBI investigates you after you tell a whole conference of interested parties how to take down a critical infrastructure.

Re:No good deed goes unpunished.

[Alcilbiades]

I really hate to side with big business or governmental intrusion, but broadcasting to the world was irresponsible. We live in a society that does have laws. He had to break the law to get the information he got so why should he be investigated. Not only did he break the law but he published his research so that malicious hackers will have a specific area to target.

It is time people grow up and realize that actions have consequences. And no it isn't THOUGHT POLICE. That idea is about "correct" or "incorrect" thought. The problem this guy had was he didn't "think" he just got an idea and went with it. What do you think the government would have done if he would have given general information about weaknesses in NORAD or some other very important national security installation. So, the moral of the story is if you find away to bypass, break, or abuse security systems that could pose a threat to the general population you best not tell everyone and their brother about it.

Re:No good deed goes unpunished.

[Stevix]

sure he settled with his company beforehand, their scope on the issue goes no further then a violation of trade secrets and treats it accordingly. just because you arent in the army, as you so put it doesnt mean you might not be privy to information that keeps it, or any other organization afloat. keep in mind that the US government probably uses alot of Cisco equipment, and is probably critical to its continued operation. Now this person tells anyone interested on disabling their networks how to do so. regardless of the intention on Mr Lynn's behalf, the FBI sees this as an open invitation for interested parties to shut down these networks. if you contracted out work to be done on something critical to your business, and the outside worker then tells everyone a way to basically screw you over afterwards, without mentioning it to you beforehand, to let you get a handle on any potential issues the new info could bring, you wouldn't feel pissed? well the US goverment does, and probably sees this as a very serious problem, now they want to make sure he doesnt have more of these goodies up his sleeve. i understand the need to question government just as much as you, but framing every action by them as some kind of totalitarian oppression kind of nullifies your point. if you cant see the issues this Lynn's expose' conjure's, then you have one eye open, but another one closed

Re:No good deed goes unpunished.

[Anonymous Coward]

"Should the police no longer respond when 911 is dialed unless it's absolutely certain a crime is being committed? Is this not what "investigation" is for"

I think the question isn't whether the government should investigate an allegation of a crime, but what is the crime being committed? What law with a criminal penalty may have been broken?

Without knowing a great deal about this case, the only laws even remotely relevant to this would seem to be trade secret law. Even that, I would think, would not apply unless he had some special relationship with Cisco (eg. was an employee, or had special access to the source code through another organization) or if he had signed an NDA. I had the impression (perhaps mistakenly) that trade secret law would anyways be a civil matter, not the subject of a criminal prosecution.

Unless someone can say that there was a complaint accusing him of a crime, what would they be investigating? Simply "doing something we don't like" or "hurts our profitability" is not a crime. And if Cisco or someone else just fabricated a charge, that's a problem (and they should, but of course won't, get into a serious amount of trouble over that).

Re:No good deed goes unpunished.

[stratjakt]

He exposed it at a hackers conference, to the same assholes who think its nifty to write an e-mail worm, or install sniffers to watch for credit card numbers.

He could have told Cisco themselves, or at the least, in security related fora.

You're the type of moral relativist probably wants to give Al Qaeda a medal for exposing the structural flaws in the WTC.

Re:No good deed goes unpunished.

[wfberg]

Bullshit. Cisco has just as much interest in ensuring their kit is safe from insider attacks as the government. If they wanted to prevent loose lips from sinking ships, they wouldn't have settled.

Did this guy publish an exploit? No. Any details not know already? No.

From TFA:
Although Lynn demonstrated for the audience what hackers could do to a router if they exploited the flaw, he did not reveal technical details that would allow anyone to exploit the bug without doing the same research he did to discover it.

i understand the need to question government just as much as you, but framing every action by them as some kind of totalitarian oppression kind of nullifies your point. if you cant see the issues this Lynn's expose' conjure's, then you have one eye open, but another one closed

I'm not a lawyer of course, but a license agreement is essentially a contract, right? Aren't you implying that he committed a crime, when this is perhaps a breach of contract? I could be mistaken.

Even if it was a crime, does that really give Cisco any rights to his work at all?

Re:No good deed goes unpunished.

[Anonymous Coward]

Yes, the FBI is supposed to investigate criminal complaints. Did Cisco make a criminal complaint? If Cisco did, then the FBI should investigate it. This investigation can and should go on regardless of whether Cisco settles any civil matter with the person.

What should NOT happen is that the FBI drops the investigation after Cisco settles with Lynn. If that happens, then the FBI has been used to bully Lynn. If Cisco makes a criminal complaint, then refuses to cooperate with the FBI, then they should be charged with obstruction of justice. If Cisco files a false complaint, they should be charged with that.

Hey, at least he's pleading guilty. While we're talking about facing the consequences for your actions, Dan Rathers stepped down over his mistake. At least the Democrats take responsibility for their massively visible fuckups.

The Republicans couldn't wave their flip-flops fast enough to flip-flop their ethics rules when DeLay looked like he might possibly be investigated for campaign financing violations. So when we have someone in the Republican administration (allegedly Rove) leaking CIA agent names, it's not exactly a surprise when Bush revises his speech every few days to cover just how serious it has to get before someone is held accountable for it. What is it now? The leaker has to be found guilty, the formation of no less than two communist countries has to be directly tied to the leak, and terrorists have to blow up the moon, and then Bush will think about firing the person responsible?

Just because you give information, that if used wrong, would harm something, as long as you're not inciting or telling people to cause harm to others....you've broken no law.

There's tons of books out there that tell you how to make an atomic bomb...perfectly legal. You can describe pressure points on the human, that can kill, etc. Information is free to dissiminate.

Honestly, I agree with the FBI investigating. If this flaw is that bad, you don't talk about it to the people that really know how to start trouble before going to a company - thats just inviting trouble. Even stating what the flaw attacks on the routers can show others where to start their own research into this flaw.

Don't get me wrong, I'm all about security, but he should have at least attempted to go through the proper channels. The FBI has basically gone after him about the possibility of the amount of damage he could have caused society - we can no longer exist without the internet.

The problem with your anaylsis is that he did NOt publish info about how to break into anything as stated plainly in the article. He only showed what could be done.

Nor did he focus any more attention than was likely there before. If you don't think people have been trying to hack those routers your nuts. Cause they had every reason to believe there was already a flaw and they were looking. all this guy did was show everyone something we already know.

Further, you are wrong that he had to break the law to do what he did. Just because the FBI is investigating doesn't mean a criminal law was actually broken. As for a civil law being broken that is debatable since the lawsuit was settled which has nothing to with his actually being liable (since you are never guilty in a civil trial iirc).

And finally the difference between this and publicly outtin NORAD is that there is little question that he would, in fact, have had to break several very serious laws to obtain that information as would the person or persons that helped him get it. So there is NO comparison between this and the disclosure of classified government information.

Re:No good deed goes unpunished.

[Flower]

Ok, exactly what law did he break? The more information that we get about the situation it becomes more and more evident that Mr. Lynn broke no law.

You can't bring up the injunction. That means nothing since the suit was settled. Mr. Lynn did not have to make any admission of wrong-doing nor pay restitution. More than likely Lynn's lawyer brought up how much it would cost to defend himself and Mr. Lynn decided that it would be better to keep making car and house payments than fight in the courts.

And it doesn't even matter that he can't talk about it any longer. The presentation hit BlackHat. I'm over here in the Mid-West and a printout of his slides are hanging outside my cube wall for any of my co-workers to go over. The stuff I'm not getting is being talked about on various blogs and I can just follow the trail of links to educate myself on what this exactly means. So where is the great admission of guilt in the injunction? Nowhere. The injunction is nothing but a PR wash for Cisco.

So what about the FBI investigation? Where are the charges? Where's the conviction? Taking his stuff and following up on Cisco's complaint is SOP for the FBI. I'm not seeing any law breaking here.

Until you've got something a heck of a lot more specific than "he broke the law and there are consequences for that" we don't have much to talk about because that axiom just isn't flying currently.

If the software is closed source, the only person that can fix the flaw is the vendor and giving presentations to a bunch of hackers about exploiting the vulnerability doesn't seem very responsible.

Bullshit.

First, Blackhat != hacker convention. It's a meeting of security professionals.

Second, while the vendor may be the only one who can fix the code, they are not the only one who can fix the problem. If I was a sysadmin and oversaw a network with serious security needs, I might consider replacing my hardware if I knew it was not secure. Cisco isn't the only router vendor out there.

Third, if the vendor knows that I know there's a problem, and that I might jump to a different vendor if I think they're dragging their feet, you'd better be assured that they will put a higher priority on fixing the problem.

Re:No good deed goes unpunished.

[HiThere]

Saying that it's all right is quite different from saying it's not as bad, or even in the same ball park, as revealing the identity of an undercover agent.

Mind you, this does depend a lot on exactly WHAT was in the document. And we don't know (well, *I* don't know). Since I don't know, in my ignorance I don't consider destroying it to be particularly bad. Since I do know (within reasonable suspicion) probable effects of revealing the ID of an undercover agent, I consider that quite bad. Probably not technically treasonous, but quite bad. Certainly ground for immediate and permanent revocation of all security clearances. From there we would need to consider what crimes might be involved. Malfeasance seems plausible, e.g.

Rove should be doing hard time, and should have his security clearances revoked, and his file marked: not eligible for government employment in any capacity at any time, now or in the future. Also not eligible for employement with any government contractor in any capacity at any time, now or in the future.

Whether or not he gets multiple decades in prison (I'm not sure he's guilty of anything except malfeasance), he should NEVER be considered for ANY government employment, direct or indirect. He is a proven, not just a suspected, security risk.

Re:No good deed goes unpunished.

[Master of Transhuman]

You obviously have not followed the story, because he did NO SUCH THING.

There was a long period where he, his company and Cisco worked on this together.

Where he parted company with his company and Cisco was when the Black Hat talk that they were to do JOINTLY was back-pedaled because Cisco lawyers and PR people decided to hush up the nature and severity of the flaw, resorting to tearing up the presentation documents and destroying the presentation CDs and threatening to both fire and sue him if he went ahead with the talk.

So he, believing (correctly or not, I don't know the details of the flaw yet) the flaw was serious enough that thousands of unpatched routers were at risk, decided to shit-can his job and tell the story himself rather than be censored by an NDA signed by his company with Cisco.

Bruce Schneier's take on this is similar - this guy was mostly in the right and DID follow responsible disclosure procedures up until the point Cisco decided to "act like thugs."

Re:No good deed goes unpunished.

[Master of Transhuman]

EXACTLY!

At this time, Cisco should be pressured by the government in the name of national security to OPEN SOURCE IOS COMPLETELY.

They obviously cannot be trusted to eyeball their systems enough to detect serious flaws, and NOW they cannot be trusted to REPORT those flaws to people who have not installed their fixes.

Therefore, IOS should be taken AWAY from Cisco and made open source.

It's ridiculous that Cisco has been charging the earth for 486 boxes with some custom chips running a lobotomized version of UNIX and then they get to call on the FBI as their enforcement arm when someone finds a flaw in their crap.

If Cisco doesn't get its act together, the Chinese will start selling high-powered Linux boxes which have routing built in to the OS and with custom chips to do everything a Cisco router does. They won't care that EIGRP is proprietary, either.

Re:No good deed goes unpunished.

[mrsbrisby]

... a license agreement is essentially a contract, right?

Wrong. In the US, you can only rescind rights through signed contract. A "license agreement" doesn't have the power to take away rights for you see, books, movies, and software are all sold, no matter what Cisco or Microsoft or the MPAA would like to have you believe- their "license agreements" simply cannot revoke rights.

What a license agreement can do is provide you special rights that you may invoke. Nobody has to sign anything because if you "violate the license" you're simply held by-alternative in the superior laws- generally those of copyright violation and whatnot.

You still have the right to decompile software and even make copies for various fair-use purposes. You can even make changes and distribute those changes.

They cannot take this away unless you sign something. You buy it, you get all the rights associated with that sale.

They say they only "licensed it to you" but that's another big lie. You didn't sign a contract: no contract means they have none of your rights in which to withold.

I dunno mister coward. Why don't we look at the reasons for treason. They are very clearly defined in the constitution (have you read that?).

Treason against the United States, shall consist only in levying War against them, or in adhering to their Enemies, giving them Aid and Comfort. No Person shall be convicted of Treason unless on the Testimony of two Witnesses to the same overt Act, or on Confession in open Court.

Mr Sandy Burgler I think fits the Aid and Comfort to the enemy (since we don't actually know the contents of the documents he stole, they could contain the names of terrorists, I know I'm stretching, but hell we don't know).

I don't know of any person in the current administration that have waged war against the united states or have given aid and comfort to the enemy.

Re:No good deed goes unpunished.

[mcheu]

I could see your argument if this fellow was in Canada, because here, some publications are banned because they promote hatred, or instruct people on how to commit illegal acts.

As the FBI is investigating, I presume this is the USA. That's where companies like the well known Paladin Press are. For those that don't know, they publish some very weird stuff. They publish books on subjects like Improvised Explosives, weapons conversions (making a semi-auto into full-auto), improvised silencers, as well as how-to's on electronics for Surveillance and sabotage. Since they're still advertising in the back of various hobby magazines, I presume they're still legal in at least some states.

What I find weird is, if stuff like that is still legal why would something like this be an issue? This is pretty lightweight stuff by comparison.

By the way, being "investigated" doesn't mean anything. Law enforcement agencies around the world "investigate" useless crap all the time. All it requires is someone filing an official complaint and it has to be followed up. You can't infer guilt just because the police want to talk to someone.

[h4rm0ny]

Does that stuff actually work. Yeah, Google for "dim mak" or "kyusho" - I have but I'm not sure I can believe it.

The answer is a qualified "no." With sufficient force, there are a few points which can incapacitate, but not kill. There is only one where there is a real chance of death and you'd have to hit it right and hit it hard. There is another point where you could do longer term internal damage again, you'd have to hit pretty darn hard (though possible).

So incapacitate, yes - there are specific points you can whack (not tap), but Kung Fu movie poke with a finger and kill is not so feasible. Which is a good thing. Men who tell you they could kill you by hitting you in such and such are some of life's most irritating and (least liked) people on the planet. IMHO.

Regarding the nuclear know-how, I think it's generally accepted that knowledge of how to make them is, if not easy, at least not a barrier to be depended on. Nuclear weapons control is nowadays focused on preventing Uranium refinement and the obtaining of plutonium. It would have helped if the US and the UK had honoured their part of the non-proliferation treaty and scaled back their armaments as agreed, but they never delivered. Funnily enough, the rest of the World doesn't go for their "but it's okay - we're the good guys" argument and now everyone needs nuclear weapons to feel safe.

Re:No good deed goes unpunished.

Nope. Mike had ben working with his former employer on analyzing possible vulnerabilities and had followed all Cisco and industry reporting best practices. The problem stems from Mike's mis-use of an ISS licensed copy of Cisco IOS. Mike based results on his analysis of a reverse engineered copy of IOS (first no -no). As soon as he quit ISS he no longer had rights to any data regarding he gathered using the IOS as it was licensed to ISS (and not Mike) - he was outside of the license and qualified as a hacker.

Then again this all about Mike Lynn marketing Mike Lynn. He made a splash and will be looking to get paid for it.

Has nothing to do with a high horse and everything to do with facts. This is not a surpise that there was a flaw; anyone who thinks flaws don't exist just because no one has said anything about it is kidding themselves.

So, given that a flaw exists, what next. Well he didn't divulge how to actually do it. so all those folks with quesitonable morals still have no more ammunition.

On the other hand, now everyone knows there is a flaw and what it will look like when it happens. so the "white hats" can keep an eye out for it.

And most important, it lets everyone know that they need to start patching now, and that the bug is more critical than Cisco made it out to be and THAT is the most important thing. Because if no one knows, no one can protect themselves and no one can put pressure on the company to fix it.

Cisco has its own vunerability submission protocols in house, be he instead showed his findings at a Black Hat conference instead

Just to clarify, this vulnerability was reported to Cisco many months before Mr. Lynn made his presentation at the Black Hat conference. (I think it was six months prior.) In addition, Cisco supposedly patched this particular vulnerability over three months ago; the problem is, not every vulnerable router has been patched.

So please, don't go insinuating that Mr. Lynn did something improper. Cisco had plenty of warning about this vulnerability, and supposedly has taken action to fix it. Mr. Lynn only presented new exploits (or expanded versions of existing exploits) for this vulnerability.

Re:No good deed goes unpunished.

[abaddon314159]

except I didn't tell anyone how to take anything down...As I've said repeatedly, and as you would know if you had read any of these articles, I didn't detail any vulnerability at all...I didn't even explain how to exploit a vulnerability if you had one...

All I did was prove that vulnerabilities are exploitable...period...tell me what is wrong with that...

The real issue is...

[maotx]

The real issue at hand, at least with Cisco router owners, is not the fact that Lynn released information concerning the exploit, but the fact that Cisco would not tell anyone about it. Time and time again has shown how security through obscurity is not real security, especially when Cisco's source code had been stolen.

The reality of it is that Cisco fixed the exploit last April with a patch and no longer offers the vulnerable IOS for download on their site. The problem with that though is that they did not inform anyone what the patch fixed and who needed to download it. Most people who are vulnerable to this attack are those who have not updated to Cisco's version as of April (which are a few I'm sure. No point on upgrading a working system with a patch that could break you.)
The real problem is Cisco and their disregard to release information over a severe vulnerability in order to press forward their new OS next year.

Re:The real issue is...

[riptide_dot]

Again... how is this "illegal".

I haven't read this anywhere, but from the start I was wondering why Cisco would think they had legal grounds to sue this guy, and then it occurred to me that since he worked for ISS, who works closely with Cisco and lots of other technology companies, that it stood to reason that ISS might have been given access to trade secrets about Cisco stuff that the public is not. If they did, maybe Lynn signed a confidentiality agreement with ISS to not divulge such information, hence the reason he quit so he could give the speech. Maybe Lynn thought he wouldn't be bound by such an NDA (if it even existed) if he quit ISS.

If that's the case, Cisco might not have been morally justified in going after him, but they might have had legal justification since Lynn, as an ISS employee, would have been one that had access to the confidential information.

How is this funny or relevant?

Since when is it evil for a law enforcement agency to follow up on a complaint, even if the complaint is later found to be invalid? Or should law enforcement agencies be able to predict the future, and just skip the investigative step, and automatically know whether a crime has been committed? It might have been absurd or vindictive for ISS and/or Cisco to approach the FBI, but when someone approaches the FBI and claims a crime has been committed, would you prefer that the FBI did nothing? It HAS to investigate, just like the police still respond to even 911 hangups. If nothing is wrong and no crime has been committed, it's dropped. But when a complaint is initiated, the investigative step MUST take place, else, how would law enforcement even function?

Perhaps the FBI is acting righteously and properly. I wouldn't claim to know.

I have no similar doubts about Cisco. Current evidence indicates that Cisco acted as an abusive bully. I have seen no evidence that indicates that Cisco had ANY valid reason to call in the FBI. I have seen evidence that indicates that Cisco had NO valid reason. It's not conclusive, but in the absence of other evidence it's persuasive.

Cisco is abusing the trust of the FBI for gain. (What gain? That's a quite difficult question. They almost have to have intended financial gain, but I doubt that will be the result. Certainly I will only recommend Cisco now if there's no feasible alternative. And I will doubt every public statement they make that can't be independently verified.)

Perhaps the FBI could file charges about lying under oath...but they probably didn't get the charges sworn to. Too willing to trust Cisco just because it was large and wealthy. (...and politically connected?) Also, I don't recall ever hearing of the FBI filing charges against someone for lying to it.

Re:1984 Called...

[dasdrewid]

I think you need to read the article more carefully. The FBI started investigating before the agreement was reached because someone had come to them complaining that a crime has been committed. Like an earlier poster said, it's their job to investigate when people claim a crime has been committed, if only to determine whether or not a crime has actually been committed. For all we know (and from the sounds of it), one hasn't, the investigation is going to be (possibly already) dropped, and that's all that comes of it.

As to pinging a router, all the FBI would hear at first is "I think someone committed a crime", told to them by the pinged party. The FBI would ask them what happened (which would be considered an investigation), the person would say they'd been pinged, the FBI would ask what else, the person would say that's it, and the FBI would probably laugh and stop the investigation. Basically, it's the FBI's job to investigate when a private citizen says a crime has been committed (and it falls under federal jurisdiction). While no one wants the FBI doing more than their job description tells them to do (the original one), I'd say it's fair to expect and allow them to do the basic job they were created to do.

One of the easiest way of ridiculing geeks in their political writings is to point out that all have only read essentially one single book relating to it, and they keep referencing it when they situation warrants it as when it does not.

Look, 1984 is about a quite extreme scenario. You do the views you expose quite a disservice by comparing something as insignificant as this incident to what Orwell wrote about. Put simply, it's quite impossible to take people like you seriously, because you are so unbelievably unnuanced in your beliefs.

And this is all ignoring the fact that you obviously haven't got a clue how the FBI works, and that you've misunderstood pretty much everything about this story. FBI most likely has simply received a complaint from Cisco, and started an investigation. That says nothing about whether the claim has merit.

What exactly was CISCO suing over? It seems to me that CISCO didn't like what he had to say, but that doesn't give you a right to sue somebody.

Did he just give up so that he didn't have to defend a baseless suit?

Was his disclosure good for the internet in the short term? Probably not. However, unless there is some law that I'm missing, describing how to use a bomb is not the same as advocating that it be used.

[daveschroeder]

First, according to this new article, Lynn would have been allowed to speak if Cisco was allowed to speak as well.

In other words, give Cisco the opportunity to explain that patching vulnerabilities in major commercial vendor-supported code isn't just something that happens instantaneously. I'm not saying Cisco is completely in the clear here, but no everything shouldn't be open source, and patching shouldn't/can't happen like it does in the open source community. Some people will no doubt fundamentally or philosophically disagree with this, but in major network infrastructure, there is a place for stable, predictable commercial support. Along with that sometimes comes commercial and/or proprietary code - code which is kept proprietary for competitive advantage. This is not to say that flaws should not be revealed for the good of all, but speaking in generalities here, broadcasting everything as loudly and widely as possible to the public isn't necessarily the best way to address issues. Nor is hiding things in obscurity. But there is a scale here, and it's NOT black and white.

Further, the FBI is investigating not because of some corporatist government conspiracy, and is not being used as Cisco's own "police force". It is investigating a claim of a complaint it received, as it is compelled to do by its very reason for existence, and doesn't even know if a crime has been committed. Would you want law enforcement agencies to not investigate allegations of crime, whatever your opinion of this particular instance aside?

Even Lynn's own lawyer says "that she thought the agency was simply following through on a complaint it received when Cisco and ISS filed their lawsuit against Lynn and that it didn't come after her client reached his settlement. She didn't know the nature of the complaint but said it was probably something to do with intellectual property and that it most likely came from Cisco or ISS.

Granick said she did not think the FBI would arrest Lynn.

"Definitely not," she said. "I don't have any sense at all that that's where they're going. I don't know what the circumstances are under which anyone contacted the FBI. It may very well be that given that we settled the civil case yesterday, this is over."

You're sort of straw-manning here. The problem isn't that Cisco didn't fix the vulnerability in time, the problem is that they didn't tell anyone it was a critical update. That's a far cry from open-sourcing their code or personally explaining how the vulnerability works.

Re:Please, don't overreact.

The problem here is that Lynn is claiming this was some kind of end-times doomsday vulnerability, and Cisco claiming it wasn't a big deal.

I'm frankly not inclined to believe either one of them.

We still don't know the EXACT nature of the vulnerability, and I haven't seen any direct evidence that the update should have been identified as critical. I realize that may be a little circular, but the only "evidence" we have of anything is the emotional factor of a respected security researcher quitting his job and nobly going forward with a presentation. While it tugs at the heartstrings and provides for good melodrama, it doesn't do much more. This is a difference of opinion about how Cisco handled a vulnerability. Should Cisco have labeled it critical? Was it really a big deal. Perhaps it was. But you can't assume that the truth is 100% on Lynn's side just as you can't assume such about Cisco. As I said in other posts, the truth is probably somewhere in between.

Re:Please, don't overreact.

[Anonymous Coward]

there is a place for stable, predictable commercial support.

Which one does cisco give that you can't get with an open source alternative? I missed it I guess, apparently open source sucks though...

Re:Please, don't overreact.

[loqi]

Judging from his paper (if it's still up), the vulnerabilities allow for total execution takeover on the router, as long as you know where to hit up the overflows. Granted that's still not the *exact* nature of the vulnerability, but it sounds pretty squarely in the "CRITICAL" category to me.

you can't assume that the truth is 100% on Lynn's side

No, but the evidence is definitely in his favor. FBI investigation, talks of trade secret violation, and Cisco hasn't denied anything stated in the presentation, correct? But they did go to great lengths to ensure that the information didn't get disseminated. Not an open and shut case, but in the truth casino, my money's on Lynn.

Re:Please, don't overreact.

[Flower]

From what I can gather and I'm no genius, so don't quote me on it.

Lynn seems to have found a way to get a shell on any version of IOS that is vulnerable to an overflow be it stack (which appears to be rare) or on the heap. The problem with exploiting an overflow on the heap is that Cisco deploys a watchdog which forces a software reboot of the device if it finds that the heap has been messed with.

Going deeper in his presentation it appears that Lynn found a way to kill the watchdog and keep the router from rebooting itself. With the time now bought by doing this one can setup a TTY and get a shell to take over the device. That appears to be the kicker over previous exploits that I've seen with Cisco kit. This isn't a DoS it is a remote root.

Ok, my flame-retardant Scoobies are properly in place, tag in back. Anything I have gotten wrong please feel free to correct with whatever amount of vitrol is deemed appropriate.

And for what it's worth: I think Lynn deserves enormous respect and gratitude from most of us.

• users are better off. As a result of his work my employer, (medium sized NSP), it's become clear that we need to make major changes, fast, to our network infrastructure m'ment... like, we need to apply patches. NOW. And get support... this is looking like a 7 figure sum,.. but we're going to be a lot more secure this time next week than we are today, and more importantly more secure than we were *before he gave his takl*.
• Secondly, he stood up for the ethical Right Thing (by resigning and doing the preso);
• and thirdly, by surrendering to the inevitable (by signing the Cisco/ISS gagging order) he's drawn attention to the deep crapness of BOTH Cisco and ISS, as well as highlighting the fuckedness of the system that allows legally-discovered facts to be very very nearly completely suppressed.

(Note: Cisco, allegedly at the behest of certain TLAs, pulled the plug on the preso only a day or two before it was due to be delivered. How many vendors are there out there who wouldn't allow a researcher to go within a million miles of Blackhat / Defcom, & who are succesfully suppressing information about critical security vulns at the expense of their customers?) Finally I think he's stood up in the name of security researchers everywhere. It sets a precedent, and a standard, for those people who find themselves in a similar position in future.

This is a dumb point. I'm sure he signed some sort of NDA in which he likely ceded his right to talk about some things.

Re:Free speech

yes, but what he is talking about isnt exactly his opinions on politics or what have you, he is expressing information on no doubt private corporate information, or a vunerability thereof. if I worked at a company, and decided to 'practice free speech' by harping all of my employers trade secrets, i would no doubt be fired for screwing over the company, based on non-disclosure agreements. considering the impact this vunerability has on the infrastucture (think about the ramifications of shutting down the internet, including government networks, etc) The FBI sees this particular information as akin to 'speaking freely' about architectural flaws in the majority of large buildings that could bring them down with little effort, incuding government facilities. maybe a little overboard, but hey, they have been investigating more people for alot less recently.

Keep in mind that the 1st Amendment is not an absolute protection against saying anything, anytime, anywhere. The classic example is shouting "FIRE!" in a crowded theatre, though I prefer the thinking of someone with a bull horn outside you window at 2 am;-)

Exactly. You would be punished by the company, not by the government, because what you had done would not be illegal but a violation of employment terms and/or contract. The FBI would have zero jurisdiction.

In the same way if you come to my house and start spewing religious garbage I don't want to hear I can refuse to listen and remove you from my property, but I still can't restrict your right to say what you believe. You can't be thrown in jail for saying it, but you can be forcibly removed from my property and made to say it elsewhere.

A company firing someone for 'practicing free speech' is simply exercising the right all of us have in a free speech society: you can say what you like, but I don't have to like it.

but hey, they have been investigating more people for alot less recently.

No doubt that makes it right.

As one of Jehovah's Witnesses, I resemble a person "spewing religious garbage". I must say that your illustration made me laugh, though!

A threat of forcible removal happens from time to time, but not often. We don't want to be forcibly removed any more than you want to do it. Just tell us politely but firmly to go away. We'll (usually) listen...

Ever wonder why we keep bothering when (almost) no one wants to hear? The next time someone stops by, tell them that you will give them no more than, say, five minutes to hear *why* we keep this up when most people don't care.

politics was an example, and if i came to your house telling you not religious zealotry but saying, "and by the way, the codes to shutdown the government are *****" and had all real knowledge of this info, you wouldnt be concerned as to why id be telling you this? the open source security model Lynn is following in his announcement is not well understood by the majority of people, including the relatively old fashion FBI. if he stated his opinion on something and got fired, id be mad, if he whistle-blew on corporate shinanigans of his company and got fired, id boycott Cisco, but he has done neither of these things. And btw, i dont live in your country, and dont care if it is fair or not that more are investigated for less, but if that is the case, arent there more unambiguous cases of government spying going on? perhaps taking more interest in US out-of control politics then work break slashdot posting is in order.

Re:Free speech

[morgan_greywolf]

There are no exceptions to the 1st Amendment. Those who point out yelling 'FIRE!' in a crowded theatre fail to understand WHY it's illegal to yell 'FIRE!' in a crowded movie theatre. It has nothing whatsoever to do with any exceptions on free speech. Your free speech ends at the point it infringes on other people's rights. The example of yelling 'FIRE!' in a crowded movie theatre is an example of infringing on others' rights -- the movie theatre owner's private property rights mostly. Yelling 'FIRE!' in a crowded movie theatre is also a crime -- it's called 'battery'. Battery infringes on other people's rights. Kiddie porn is illegal because it involves the sexual molestation of children -- which is a crime in all 50 states. Again, infringing on other people's rights. But who's rights are being infringed on in this case?

Re:Free speech

[Shadow Wrought]

If your copy doesn't show it either, then perhaps either you are wrong, or America doesnt really have a Constutution after all, but instead has a nine-headed Pope!

Welcome to nine-headed Pope land! It is far easier to argue that the 1st Amendment has no limits on it whatsoever than to accept that life is not composed of absolutes. If you believe that any manner of speech is fine, you are more than welcome to your views (and kudos to your tenacity). However, you should also note that the language of the 1st Amendment specifically states that "Congress shall make no law..." That means that it provides protection only from Federal prosecution and meddling. The 1st Amendment only applies to the 50 States because that same nine-headed Pope which you deride applied them to the States. If you want to accept that the nine-headed Pope does not have the power to interpret the Constitution, than you also have to accept that your State is thereby free to restrict your speech in any manner it wishes, without being burdened with Constitutional considerations.

Your choice. Personally, I prefer to accept that our society is far too complicated to limit ourselves to the extremes of interpretation.

Odds are I would never personally think of forcibly removing anyone for religious speech on my property. Depending on what's being said I might remove my children from the room, however.

But I thought it made a great illustration for free speech rights and property rights, one that most people here would get. Probably all of us would look into forcible removal if someone came into our home and refused to leave, regardless of their message.

On the other hand, knowing about the problem I can now take steps to mitigate it by, for example, making sure my back-up routers are not made by Cisco, or by replacing vulnerable equipment with other types that aren't vulnerable. Of course this would hurt Cisco, which is the reason IMHO they tried to shut the guy up.

Re:Wait, let me get this right?

[Linus Torvaalds]

So what you are saying is that it's a really bad thing for Cisco to cover up a problem that can cause that instead of fixing the problem?

If only companies weren't allowed to cover up something like that. Oh wait, employees with consciences could blow the whistle. Oh wait, one did, and then he was threatened with a lawsuit and investigated by the FBI.

No, covering up a wide-affecting vulnerability should ALSO have consequences.

However, spreading the vulnerability is ALSO just inviting someone to use it.

Sure, Cisco would have to fix it then, but the damage would already be done...

You think too much in blacks and whites, saying 'spreading that information is not a good idea' does not mean that Cisco is doing right, there is a possible conclusion that can be drawn (that I have drawn) ... that says BOTH are wrong...

Re:Wait, let me get this right?

[mister_llah]

It would be better then, to just blow the whistle without giving specific details which could be used to "bring the Internet to its knees" ...

Cisco would be hurt, no secrets would be divulged, and Cisco would still try to fix the problem before it was discovered...

Of course, without the specifics, the information may be seen as less valid, but if they investigate the source, and the source is a trusted expert (as in this case) ... then why do you need to know the specifics? ... I'm sure Lynn contacted Cisco, also, and notified them of this vulnerability...

Re:Wait, let me get this right?

[Todd Knarr]

I need specific details for a couple of things. Firstly is to evaluate whether this is a real problem. A lot of problems are highly configuration-specific, and I need to test not just whether it's a problem in the general case but also whether it's a problem that I can be bit by given the configuration of my particular network. In addition, I need to be able to test any fixes Cisco might put out. Vendors have had histories of putting out "fixes" just to say they have, but the fix only deals with the one particular example and leaves everyone exposed to even trivial variations on the original attack (eg. dealing with Code Red by blocking the one specific URL string used, leaving you vulnerable to Code Red with one character in the padding changed).

I keep seeing how vendors react, and it's always "the researchers need to compromise". The vendor's position is always "no release of any information period". We gave them right of first notice, we gave them time to fix the problem before details were released, and after that they still seem to want more compromises. I've become convinced that they won't stop compromising short of their own position, and that as long as that's the case the only response can be no compromise at all.

Re:Wait, let me get this right?

[finse]

However, spreading the vulnerability is ALSO just inviting someone to use it.

I disagree. Lynn did not provide the details to exploit the vulnerability. I think discussing the security flaw invites the vendor to CORRECT it and to provide advisories to its customers. Its possible that nefarious organizations already know how to exploit this issue and could be at the ready to use it for evil. IMHO By disclosing this to the public, Lynn provided me and my country a service.

Re:Wait, let me get this right?

[megarich]

While I don't agree the practices of Cisco, you are right. If the net even went down for one hour everyone including /.ers will be freaking out. I mean no /. for one full hour oo the humanity ;)

Back to a serious note, while I see many posts about how this is handle wrong by Cisco, I would like to ask how Cisco should handle it? Personally I feel you should let the customer at least know its an critical update but if you divulge too much information then you risk having your systems brought to its knees just like some of these vulnerabilities in windows that have patch fixes.

Well I gave my 2 cents I definately would like to hear how others would handle the situation.

Re:Wait, let me get this right?

[bastardoperator]

Just a question, is it the end of the world for any one other than cisco and a few incomitant network admins, if there is ever an expliot for this in the wild?

Re:Wait, let me get this right?

[mabhatter654]

Cisco had a 4 months since he reported it to THEM!!! They made a "token" fix but in a normal patch release but didn't notify their customers of how extensive the flaw really was...

If their "secret sauce" runs the internet to the extent everyone is crying about, then it's their DUTY to admit they have long-standing issues they need to fix. After all, Cisco is the company making Billions selling a flawed product here .. this guy's just pointing that out.

This doesn't pass the "fire in theater" test

He wasn't revealing state secrets, and he didn't "yell fire in a crowded theater."

Someone should challenge the trade-secret-protection criminal laws on 1st ammendment grounds - yes, there is tort, and yes, restraining orders may be appropriate in rare circumstances, but a criminal conviction, I think not. It's time to give the local jury pool a lesson on free speech and jury nullification.

I hope they drop this ASAP, and if they don't, the ACLU should get involved. This is America, not Soviet Russia.

Re:This doesn't pass the "fire in theater" test

[tulare]

I'm not saying I agree that the FBI should be involved in this horseshit (I don't), but the way "Trade Secrets" tort works is that you sign and swear to an agreement to NOT disclose certain information. If you break that agreement, you've violated a contract and an oath, and the other party is legally entitled to go after you.

On the other hand, I think this is a case of someone making an ethical decision to violate an NDA because, by his lights, the risk he faces is not as bad as Cisco continuing to have cranio-rectal inversion syndrome over this, not to mention all the half-brained dipsticks out there who haven't applied the months-old patch that fixes most of the problem.

Ethics versus NDA... it's a choice I haven't had to deal with, and for that I'm thankful.

Actually, he -did- essentially yell 'fire' in a crowded theater. However, there was smoke, and thus it was a reasonable assumption that there was fire accompanying it, and that it simply had not spread widely enough for anyone to notice.

The mere existence of the vulnerability on such a popular piece of routing hardware likely would result in someone, somewhere, knowing about it and biding his/her time for the right opportunity to exploit it. The odds are pretty good....

Someone shouting and scaring people over a bogus risk should result in punishment. Someone shouting about a real risk should be rewarded. At least htat's how it used to work before 9/11....

Re:I hope they nail him to the wall!

The problem isn' that Cisco hadn't fixed this problem. They did, months ago. BUT, they didn't tell anyone what their patch fixed, so there are people out there running old versions because they don't know that the patch is CRITICAL to their security, mostly out of fear of munging their network up with a new IOS version.

Re:I hope they nail him to the wall!

[maotx]

there are channels he could have gone through that would have made Cisco aware of the problem (if they weren't already) without endangering the safety of the nation's network by talking to a bunch of black hats!

Two things:
First, Cisco was already aware of the problem and had released a patch for it last April.

Second, Blackhat is not about blackhats. It is about security and is visited by some of the most renown security professionals including ranking officials in the CIA, NSA, and other 3 letter acronyms.

Nice job FBI. Why not halt the free flow of traffic reports while you're at it? Terrorists could use those too you know.

Re:I hope they nail him to the wall!

[LurkerXXX]

He did inform them. Many months ago. They've had a fix out for 3 months for part of the problem he pinted out. They haven't fixed the rest yet. He went through the right channels. They haven't fixed it yet. There have been many many examples with them, Microsoft, and even recently mozilla, where bugs were reported and the vendor took over a year to finally getting around to fix the problem. And that was only after the problem had been 'leaked' to the public.

The hole exists. Sometimes it takes shouting about it to get it fixed. He gave them time. If you think 3+ months is enough time or not is a debatable point. But he DID notify them through channels.

What's happening to Cisco?

Or has our industry degraded to the point that incompetence is rewarded, and vigilance is punished? Why on earth would Cisco or anybody else even bother *trying* to write secure software if this is how they react? I guess lawyers are cheaper than good programmers?

Personally, the real victim here is you and I or any admin who has to deal with Cisco junk. I can't tell my clients if they are secure.

I hope Cisco reveals the full technical details of this problem as quickly as possible. The only reason I use Cisco is for the hardware. The software is closed-source and I have to trust Cisco to keep it secure. They dropped the ball completely.

Re:I hope they nail him to the wall!

[99BottlesOfBeerInMyF]

before everybody starts yelling about the need for these things to be reported, there are channels he could have gone through that would have made Cisco aware of the problem

Cisco was aware, in fact they were originally supposed to be co-presenting with him. Lynn contacted them four months ago. The problem is many of their customers were not aware of the problem, and despite reports to the contrary, while the exploit used to get onto the system has been fixed for a while, the ability to run arbitrary code has not. Now Cisco is working to abstract their hardware layer. Put these two items together and you get new routers, with a flaw, where a single, generic exploit can take them all out.

I know a lot less about networking and networking security than Mr. Lynn. I am willing to believe, however, that he would not give up a good, paying job and risk his future employment prospects unless he felt that this was a real and serious risk. Whistleblowers need to be protected and companies that willfully disregard warnings that their incompetence is threatening vital business and communications infrastructure around the world are the ones who should be investigated, not Mr. Lynn.

[Infonaut]

Again... how is this "illegal".

The FBI is most likely investigating to determine whether there is a case against Lynn. If they find something in the DMCA that he has run afoul of, most likely they'll prosecute.

I've been writing letters to my Congressman and Senators about the DMCA for some time, but they're not listening. Until we can get legislators in office who actually understand how the DMCA casts a chill on issues like the Lynn fiasco, this sort of thing will continue.

My feeling is that unfortunately this just isn't a big enough issue on Joe Citizen's radar. There's a war in Iraq, the government is spending money like it's going out of style, there are disagreements over almost every social issue imaginable, and that monster SUV he bought last year now costs him $85/week to fill up. Some computer guy revealing Cisco vulnerabilities isn't high on his list, so it won't be high on his legislators' lists either.

While I would be the first to agree that a healthy amount of cynicism is, well, healthy, too much cynicism is as dangerous as not enough. The truth is that there are still lawmakers who value the opinions of their constituents, especially if their constituent attempts to educate them on an issue that they were ignorant of.

It may not look like it from the outside, but I would suspect that the majority of lawmakers still attempt to cling to the ideals they started with and, when given the opportunity, will attempt to act according to them.

Polititians still respond to the public on issues that the public is interested in. They listen to lobbies when they can't hear anyone else talking.

I'm basing this on a few friends who have volunteered at various political establishments.

Granted, they still lie like rugs ("We're looking into it", etc.)

Lobbies are effective because they can't be easily fooled and follow up. You can have grass roots lobbies. Look at the NRA. People call it the "Gun Lobby" but it has power because it has a lot of grass roots support.

I'm glad you still have the proper democratic reflex a citizen should have when confronted with issues, but really you should realize "writing to your congressman" nowadays amounts to pushing a button that's been disconnected.

The powerful have always had more influence on elected officials than average Joes. No doubt about it. But particularly on issues that are not on the top of your representative's agenda, a concise and well-articulated opinion can matter. The most successful politicians are those who follow Tip O'Neill's dictum that "All politics is local." It is of course easier to make things happen at the local level, because the constituencies are smaller. But Congressional staffers do take note of the letters that come in, and they let their bosses know how they are trending. The flip side of the frequent complaint that politicians will go whichever direction the wind pushes them is that when they hear enough voices from their constitutents, they will act. After all, the next election is always just around the corner.

I don't assume that my individual letters make a difference, but I do feel that when I have more involvement in the system, my gripes are more legitimate. I am taking the time and effort to be a citizen, and while my efforts may not result in any change, I know for certain that not doing anything won't help. I'd say apathy only encourage a less democratic process, because when we expect less from our institutions, we are rewarded with less.

Actually it works exactly like that.

A secret flaw exists, but nobody knows about it for a while. Eventually, it is discovered. Maybe by the programmers (happy-in-pants scenario), maybe by the Road Runner (here, Mr. Lynn), and maybe by a 1337 |-|A>

Sounds like Mr. Lynn had the decency to extend a plank under Cisco before pointing out the lack of ground.

Makes you wonder what happened to the kid in the "Emperor's new clothes" yarn. Me, I suspect public torture and beheading, just to keep the peasants in line.

I do wonder why Cisco thinks that'll work for them.

Do you have any idea who is at Black Hat these days? It is a huge security convention sponsored by hundreds of major computer and security vendors, even Microsoft is a sponsor. Heck the Department of Defense, the Army, West Point, Stanford Law School, etc. all had people giving presentations. If you want to get the word out when a major threat is being ignored, blackhat is a pretty good place to do it. It seems to have worked, don't you think?

Copy of presentation/notes?

[Kiaser Wilhelm II]

This sounds like another DeCSS.

If anyone has copies of the stuff Cisco wants censored, we could all host it and make torrents of it. Those who are less brave can use something like FreeNet to host it.

If hundreds of thousands of people host it, it will be a giant embarassment for Cisco and there will be nothing the authorities can do to stop it.

Re:Copy of presentation/notes?

[Anonymous Coward]

DeCSS was spread because many people would find it useful for watching movies.

The only point of spreading this would be for people to be able to exploit Cisco routers. The presentation may have been useful, because Cisco might now do something about it, but spreading this will serve no purpose other than to embarass (your word) Cisco, and cause harm to others.

I don't see how the two are even remotely similar.

Re:Copy of presentation/notes?

[Kiaser Wilhelm II]

No, DeCSS was spread as a political statement. Do you not remember the t-shirts, the music files, and all the like that came directly as a result of the DeCSS ruling to protest the blatant violations of the 1st Amendment by the court?

The point of spreading this is to show that free speech cannot be stopped, not matter how hard our government or Cisco wants and tries.

I wonder what would happen...

[Todd Knarr]

I wonder what would happen if a large user of network equipment, who depends on that equipment operating properly to stay in business, filed against Cisco on this? After all, they know how dependent others are on their equipment, they knew their errors in coding had put those other people at risk, and they not only didn't do anything about the situation they actively tried to block information from the people who'd be harmed. Seems to me that if a dangerous situation existed and the person responsible for it actively tried to keep the people endangered from finding out about it, that's usually grounds for additional penalties against the responsible party.

Well if ya ask me...

I am willing to believe, however, that he would not give up a good, paying job and risk his future employment prospects unless he felt that this was a real and serious risk.

How do you know this? That seems to be what everyone is basing their assumptions on the seriousness of the vulnerability on. I'm sorry, but people quit and resign over petty conflicts all the time. Just because this person is a security researcher doesn't make him a martyr, and doesn't necessitate that his resignation was some noble act for the good of the global internet community. You and he may believe that it was, and I'll be willing to consider the possibility that it was as well.

But the real issue here was that Lynn didn't want Cisco to speak at the forum with him, essentially giving its side of the story, instead of a somewhat vague assertion that Cisco's general irresponsibility will someday lead to an exploit bringing the internet to its knees. There is no specific outstanding vulnerability. Merely an assertion that Cisco didn't handle a previous vulnerability, which Lynn alleges was serious (but we don't know that for sure), urgently enough. I'm sorry, but someone quitting their job doesn't lend more credibility to the facts of a claim. The facts themselves, however, would.

Cisco discloses actual vulnerability

[mdouglas]

Crafted IPv6 packet vulnerability.

http://www.cisco.com/warp/public/707/cisco-sa-2005 0729-ipv6.shtml

http://www.eweek.com/article2/0,1759,1841669,00.as p

Upshot is that if you aren't running IPv6 on the router, this doesn't affect you.

Re:Cisco discloses actual vulnerability

[maggotbrain_777]

True, Cisco did release this announcement of _a_ vulnerabiltiy; but, if you take a look at the pdf of the presentation that Lynn gave at the Black Hat conference, you will see that this is not directly related to what he is demontrating. His is a genreal approach to identifying and potentially exploiting IOS code. What Lynn revealed is _not_ tied to a particular IOS code rev, protocol, or Cisco device. In other words, any IOS is still potentially vulnerable. Unfortunately, Cisco, while trying to keep the horse in the barn, has instead set the barn on fire, in lending far more controversy to this issue.

Re:Cisco discloses actual vulnerability

[Frank T. Lofaro Jr.]

Crafted IPv6 packet vulnerability.

So what, there are like 6 people affected by this?

Only thing IPv6 has done for me lately is bite me in the ass.

Apache 2 + Solaris 8 + IPv6 in Apache by default + IPv6 in OS by default + IPv6 not configured by default = many erros about being unable to contact listener.

Ironically, I'm an IPv6 supporter but it seems no major ISP will even route those packets.

So if Al Qaeda or whoever wanted to do an exploit, they'd have to get physically on your network, it which case they could just shoot you or bomb you or something.

Re:Cisco discloses actual vulnerability

[Anonymous Coward]

In North America, which has a few million people and half the world's IP address allocation? Sure, maybe there are six users.

In the rest of the world, which can do the maths and see that it doesn't have one IP address per /house/ let alone per person or per Internet capable device, well... those people are going to need addresses from somewhere, and despite all the endless hacks being implemented that's going to mean IPv6 sooner rather than later.

My home ISP and my employer both have native IPv6 (albeit the employer is a university, and thus perhaps ahead of the curve) and in most of Europe anyone with an IPv4 static address can get IPv6 tunnel service for the price of one configuration setting (anycast 6to4 = on).

So while I watched the NOAA undersea exploration shows via IPv4 from Internet2, I watched the BBC's Space Shuttle launch coverage and the London Bombing live reports from IPv6 multicast.

anonymity

[harkabeeparolyn]

If Lynn just wanted to help people, he could have published his information anonymously. But he wanted to use this to build his reputation so he has to take whatever lumps he finds in the refined sugar of fame.

The lesson to be learned here is that full, immediate and anonymous disclosure is the best way to publish vulnerabilities. It's too bad that vendors and law enforcement have scared the shit out of such that this is necessary, but they too have to live with the consequences of their actions.

This piece of information wants to be free...

[aquila78]

As a consumer I think I have the right to know about this. Giving the vendor some time to fix the bug is the usual procedure and is common courtesy. I don't know if Lynn gave cisco a window to fix the bugs. I know from experience how vendors can sometimes try to pull this window forever. At some point, the bug must be exposed. This way vendors are forced to fix their sh.. Maybe Lynn exposed this prematurely, which should probably have some consequences for him professionally (but legally? I don't think so) The real villains here are Cisco: An important point of full disclosure is that the bad guys and the good guys have the same information at the same time. This is opposed to the bad guys having the information, while the good guys are in the dark... Which is the present situation: Cisco are leaving their customers in the dark right now. Cisco is definately in the wrong covering this up. (How am I supposed to protect my cisco router if the details of the attack are secret). I am sure the real "blackhats" are exploiting it this very moment. So what Cisco is doing is basically giving the blackhats free hands while tying up the hands of their customers. Somebody should sue the h... out of Cisco!

Or let's put it another way

[Sycraft-fu]

If you call the police, and claim someone stole your TV, tell them who it was and where they live, the police will investigate that person. Why? Well that's their job. If it turns out you were making shit up, you might get in trouble for filing a false police report later, but they'll still investigate the person. They don't just assume you are lying, I mean unless they investigate and reach their own conclusions, how will they know?

We want the police (the FBI is just the federal police) to investigate reports of crimes. We want them to do so in as unbiased fashion as possible. We don't want them to just assume that reports are false unless they are presented with overwhelming evidence, we want them to go and look for their own evidence and reach their own conclsuions.

Re:I hope they nail him to the wall!

Details of Cisco security hole

[wfsavenger]

Either this has been posted or soon will be. To me, this doesn't seem like the "massive Internet outage" risk that Michael was talking about...

Cisco Internetwork Operating System (IOS®) Software is vulnerable to a Denial of Service (DoS) and potentially an arbitrary code execution attack from a specifically crafted IPv6 packet. The packet must be sent from a local network segment. Only devices that have been explicitly configured to process IPv6 traffic are affected. Upon successful exploitation, the device may reload or be open to further exploitation.

Cisco has made free software available to address this vulnerability for all affected customers.

There are so many things wrong with this its unreal. First off is (seemingly) a Corporation influancing the FBI, a Federal Law enforcement adjency!

The bottom line is that Lynn is a whistle blower, and the FBI should be investigating Cisco for innappropiate conduct by trying to hide (not fix) a serious vunrability that could effect the entire country.

Yes, the next person to discover such a vulnerability should carefully document it, bring it to Cisco's attention in no uncertain terms, and then wait. I understand he waited four months, but the time to strike (that will have an impact on how these issues are handled in the future), is AFTER someone has been harmed by the exploit, and the injured party's attorney is looking for discoverable evidence to support a sizable lawsuit.

I am not really that well versed in American law... but I am pretty sure if a Corporation that ran the Power distrabution or perhaps the Communication for a large chunk of the country was found to have serious security problems that they knew about and tried to cover up instead of fixing that the gouvernment would be very interested in said corporation and that serious action (most likely legal) would shortly follow. Not to mention it is just plain wrong.

The internet and the various other networks, for good or ill, are a major part of a developed countries (particulary the US) infrastructure.

I am 100% sure there are a whole slew of laws in which they could "possibly" be in violation of.

However I am not sure if you RTFA as I am unsure why Cisco would be indicted under the anything to do with 'free speech'. The article and my response had nothing to do with free speech.

In Fact I am pretty sure you didn't even read my response as I didn't beg anyone to 'be indicted for some unknown law'. I had suggested that they be "investigated" for a breach of law. The whole point of my article being, why is Lynn being investigated and not Cisco.

So following that logic, you not reading either article, yet posting an inflamatory response, one could simply assume you cannot read.

Cisco already HAS a fix. AND HAS HAD that fix out since April. They are pissed because it was exposed that there was a SERIOUS flaw in their previous IOS software, which Cisco had not disclosed to the public, even though they made a patch, and basically told people that it was an update, NOT THAT IS FIXED A MAJOR SECURITY FLAW, since that would cause the public to think that Cisco screwed up, and we can't have that can we?

Actually, if you look at the presentation you'll see he presented a walkthrough of exploiting the shellcode which Cisco has done nothing (yet) to mitigate. The (fixed) exploit he mentions was merely an example of how to get on the box, but there are obviously going to be more ways to do that and quite likely someone already knows some of them. He also explains that while this is not the end of the world, the hardware abstraction Cisco is pursuing will make this type of attack work on many more routers.

Obviously as soon as the press gets involved all sorts of misconceptions, simplifications, and dramatization immediately drowns out the factual info. I don't know Lynn, but I know a number of people who do and from what I have heard he is probably trying to do the right thing.

As for Cisco wanting to have their fair say, it was my understanding that they were originally going to present the flaw with him, but backed out. Perhaps I was misinformed.

Why pull the presentation in the first place?

[Anonymous Coward]

Does anyone know why Cisco and ISS waited until virtually the last minute to compell Lynn to drop his presentation? So far from the accounts that I've read there's been no information as to why Cisco suddenly reversed it's position on Lynn's presentation. Could Cisco have been under pressure by DHS to not allow Lynn to disclose the vulnerabilities? Nobody seems to know what Cisco's motives are here.

It never ceases to amaze me that companies and the government can take this kind of action for somebody merely giving a presentation on the security vulnerabilities of a router, or a chunk of code, or how to bypass encryption. What the hell has happened to us?

When I was growing up, my grandmother told me there's three things I should never talk about in public: sex, politics, and religion. I guess now we can say the three things you should never talk about in public are security vulnerabilities, P2P, and political dissent.

Lawyer's quotes

[hotspotbloc]

As I'm sure you know most lawyers involved in a high profile case will commonly talk it up, putting the best possible face on it in public while having a different, private opinion. This is a good thing, not bad, and a realistic part of defending a client. Negative comments could quietly taint a jury pool. Imagine something like this:

But Lynn's lawyer, Jennifer Granick, confirmed that the FBI told her it was investigating her client.

Granick was quoted as saying "Oh God! Oh God! Oh God! What am I going to do? I mean this guy did something, right or wrong, and is going to end up in a dog cage at Gitmo and there isn't jack shit I can do about it!" She then crawled into the fetal position on the ground holding her briefcase like an infant child.

"I think the best thing we can do for Mike," she said, "is to help him stock up on soap-on-a-rope and cigarettes."

Re:Lawyer's quotes

[daveschroeder]

Sorry, but that's not right.

Defense attorneys will, yes, paint their client in a positive light, however, if they feel that their client is being unfairly persecuted (or want to portray it in that light), they will most definitely play that up. In other words, the lawyer is not downplaying the FBI investigation to put a positive light on it; what she said is almost positively the truth: the FBI is following up on a complaint, as it has to do, and there is nothing more to it. Wired (and slashdot) is trying to make hay of it as one of these "OMG! The big bad jackbooted totalitarian government is going after a noble whistleblower on the part of its corporate minions!!" type stories, except that it's not. She's not even shopping around the story herself.

No way.

If you tell companies like Cisco "it's okay to write garbage software, some good samaritan will report it 'through the proper channels'", what exactly is the incentive for them to do better next time? And why the hell do *we* have to do Cisco's work for them? Mr Lynn has no obligation to Cisco whatsoever. I don't even know why he bothered waiting, put this info out THE MOMENT YOU FIND IT.

Cisco should feel *something* when they fuck up. Lower market share, lower revenue, bad PR, whatever. Not hand-holding and pat on the shoulder and "that's okay Cisco, do better next time".

This is serious stuff, I don't want Cisco to think they can call the lawyers whenever something like this happens. I want them to sweat.

So you didn't go through proper channels...

[Nom du Keyboard]

Next time he should just post the vulnerabilities to /. as AC. Clearly Cisco would rather punish him than fix their problems.

In the mean time, time to do a Freenet search for his paper. I can't believe all of the copies were destroyed.

I looked at the presentation!

[putko]

I read the presentation. (here).

Lynn shows how to do a remote exploit on Cisco's firmware. This is impressive because the router runs software that attempts to detect inconsistencies. It will reset itself and start up afresh. The big deal is that Lynn shows how an exploit can fix things up and avoid those measures. Basically, his technique is like a ninja, that breaks into a building through a window, but then immediately reassembles the window before the security guard making his rounds can notice that the window got destroyed. That's it!

There's no indication Lynn stole ANYTHING from Cisco, or broke any law.

Lynn apparently "reverse engineered" the OS in order to do this. That's usually fine; it is his right to do that.

Considering this, I'm pretty pissed that Cisco's spokeswoman, Mojdan Khalili, said that Lynn broke the law (without saying what law it was). I think that could be libel (or slander -- I'm not a lawyer) -- in any case, Mojdan Khalili, working for Cisco, just ruined this guys rep, and sicced the FBI on his ass.

Perhaps if you write her, she will get Cisco to ask the FBI to lay off the good researcher (ask her to have Cisco "take it all back"). From yesterday, here's her contact info:

978-936-1297 mkhalili@cisco.com

Also, some total jerk looked up her address and posted it (here). I think that's totally inappropriate; if you show up on her doorstep and bother her, I hope she calls the FBI on you, you freak!

Re:I looked at the presentation!

[Anonymous Coward]

There is no indication to you, Slashdot Guy. You see, the reason we have organizations like the Federal Bureau of Investigation is to investigate and decide whether a law might have been broken.

Maybe you should leave it up to the people whose job it is to decide whether there is any indication a law has been broken.

Remember the guy that worked for Intel that was accused of conspiring with terrorists, and everyone on Slashdot was aghast that anyone could make such baseless accusations? Yeah, well, it turns out, he was was conspiring with terrorists, and somehow, that story never got posted on Slashdot. (lookup Mike Hawash). So, take that, armchair detective!

Re:I looked at the presentation!

[HiThere]

Considering the public accusation that she made, I suppose that publically posting her contact informatin is reasonable. I don't think it will have any good effect, however. She won't even understand why you consider that she has the morals of a starved rat, without the excuse.

Perhaps it would be better to let others at Cisco know how you feel, or to recommend products by other vendors that you would recommend as alternatives to Cisco products. Only someone with "standing" is allowed to succeed by filing suit. (That, or someone with a few million they don't mind throwing away.)

OTOH, slander or libel (libel probably) and defamation of character suits seem to be quite reasonable responses.

P.S.: Just because you can't call off the FBI after you sic them on someone doesn't absolve you of guilt. I have not forgiven Adobe for a similar act (Skylarov), and I don't intend to. Whenever I see a chance to do them a bad turn (cheaply, I admit), I do not hesitate to do it. Unless new information comes to light, Cisco is joining Adobe in my "premanent bad books".

Re:I looked at the presentation!

[Beryllium Sphere(tm)]

>Lynn shows how to do a remote exploit on Cisco's firmware.

That leaves the wrong impression.

Someone who looks through Lynn's presentation won't know how to turn a heap overflow into a remote shell.

Lynn deliberately left some details as vague outlines and skipped others altogether precisely because he didn't want to tell people how to own Cisco routers. He wanted to prove that someone can exploit buffer overflows on IOS.

Re:I looked at the presentation!

[putko]

They could have just called the local cops or state police. Did they really have to call the Federales? That seems a bit extreme. It looks like a simple case of reverse engineering.

Also, there's plenty of info that Cisco was cooperating up to the very end -- there was no big surprise. He just didn't do exactly what they wanted.

Hopefully the FBI will see it that way, after they investigate. And I hope homeboy's affairs are all totally clean, so that the FBI wraps up quickly. Now I get why people just release this info anonymously.

That story of the jihad guy is really something! But in that case, it wasn't that he was hacking for Osama. He just happened to be a jihad-lovin' software guy. I hope they "go Taliban" on him in prison. I hear the blacks are really hard on people like him.

So much for Cisco being the good guy

[Anonymous Coward]

I've lost all respect for Cisco over this. You'd think he'd thank the guy for the heads up on the defect and also for NOT revealing how to exploit the flaw.

Shame on Cisco for not taking the high road on this. It is precisely the kind of behavior that Cisco exhibited that has caused many people to hate Microsoft and dump Windows in favor of Linux and *BSD.

Does this mean the beginning of the end of Cisco's dominance in internetworking, and the rise of Juniper and others? I hope so, because if Cisco were knocked off their pedestal as a backlash to their idiotic tantrum toward Lynn, it might force them to be a bit more forthcoming, and possibly even downright friendly toward people who report bugs in their system.

Disclaimer: I have no affiliation with Juniper and do not stock nor do I recommend their products (but may in the future). I do sell Cisco products and DO like their products but I find their attitude regarding and response to this matter beyond deplorable.

Furthermore: why the F*** are they getting the FBI involved when reverse engineering is 100% legal?

Whistleblower's Failure to...

[mpapet]

Execute the delivery of the information in a way that protects him is what's got him in trouble.

This guy's smart enough comprehend the exploit, he utterly failed in communicating it.

Never in a million years do you just blurt something out like this. I don't care how bad it is. Figure out the proper channels and work them.
That's what a focused and intelligent adult interaction with the world looks like.

Now, I admit he needed a Karl Rove power broker/media bulldog to keep the story from spinning against him. But he really needed to spend some time figuring out how to deliver the message to insulate himself better.

Shades of Adobe?

[Valdrax]

Is anyone else feeling a little deja vu here?

A big software company gets mad at a researcher giving a speech on a security flaw in their software and attempts to sue them. They get the FBI involved before realizing that they're taking a lot of PR damage and then suddenly act all buddy-buddy with the person they went on the attack against. In the meantime, the FBI doesn't give up just because the company now wants to polish its image, and the researcher's life is negatively impacted.

Sounds like Adobe and Dmitri Sklyarov, doesn't it?

I don't think they are investigating Lynn per say but the Information that he has found. There is a problem were software and hardware vendors keep this type of vulnerablity information sacred ( so they can fix it){bullshit they don't want to spend the extra money to fix it}. In any event i think we will see this investigation turn to cisco. This is a National Security Issue and If it's True that Cisco has all of this information and has been sitting on it, then i hope the government through the book at them. And my friends say why to you have 4 internet firewalls, well besides the paranoia it's just extra defense.

Learn a lesson: Some examples

[tod_miller]

Woah, that ladder does look safe!

WRONG! you are no longer allowed to point out potential security weaknesses to people who have paid money for something. Discussing the weakness of a product is wrong, and will in fact lead to the ladder breaking by itself. Inform the ladder manufacturer, and I am sure they will recall all ladders sold.

For fucks sake, everyone has no idea about security, there is no such thing as security in computing ONLY programs that are sub-standard and do not do their job properly.

Since this has become mainstream, the whole ideal has become warped, and not the onus is on the consumer to bear the risk, IN SILENCE, for fear of prosecution, because it is illegal to discover and discuss the flaws in software you have paid for.

This guy is a consumer, he paid for and analysed his product, which is no more different than talking about the fruit you bought at the market, or the shaving cream you use. He voiced his opinion that stated that the software was buggy, and would fail under certain circumstances. Not allowing him this right, or anyone else is wrong, and you cannot put the onus of security in shutting up everyone and anyone, because the next person will not nicely talk about it, but strike, oh no that will never happen. Code red, slammer, and a million other worms have costs BUSINESSES who pay the fucking FBI's wages BILLIONS. SO GO AND FUCK YOURSELF FBI, YOU FUCKING IGNORANT PIECES OF SHIT

Companies should offer rewards for patching

[EMIce]

They could always pay to have it fixed. The author says much of the code is secure, so why not take undertake a massive effort to overhaul the suspect portions, and then offer a $75 cash incentive for each router a tech patches or a substantial discount for a replacement router? They do have serial #'s so patching could be tracked, perhaps they could even use some relatively inexpensive hardware or software verification module. It could generate a code to verify proper patch status, or even incorporate patching functions in this simple device.

This might hurt business less in the long run than a widespread, debilitating breakdown. It will be expensive, probably ~$120 a pop in the end, considering payout, as well as the cost of verification hardware/software devlopment and production, but they'll reduce the destruction for their customer's businesses and to their own image.

I don't know just how much this would cut into Cisco's revenues, which would of course reduce short term profits and thus investment interest. Someone up there should be weighing something like this though, however painful it sounds. It would also set Cisco apart in market where cheaper competitors are taking away Cisco's profits. How many of them would go to such lengths in the event of a vulnerability? Companies love insuring themselves against everything.

The Obvious Question

[shareme]

The Obvious Question.. Is releasing trade secrets by a non contractual party a civl case or criminal case? If its civil than FBIO i snot investigating on Trade Secrets calims but soemthing else such as Code Stealign and etc.. Remember, our security hero was not a contractual party ot any cisco product..or am I worng on this point?

You are making a *LARGE* assumption...

[schon]

In other words, give Cisco the opportunity to explain that patching vulnerabilities in major commercial vendor-supported code isn't just something that happens instantaneously.

He gave Cisco *FOUR MONTHS* to fix it, which is hardly "instantaneous".

Re:You are making a *LARGE* assumption...

[Anonymous Coward]

Yes.

And it was fixed.

So your point is...?

See, it's not that it wasn't fixed. It was. Lynn's problem was that he didn't think Cisco identified the issue as urgent or critical enough. Just because he went apeshit about it doesn't make him right.

Cisco issues advisory

[SpaceLifeForm]

http://www.cisco.com/warp/public/707/cisco-sa-2005 0729-ipv6.shtml

Cisco Internetwork Operating System (IOS®) Software is vulnerable to a Denial of Service (DoS) and potentially an arbitrary code execution attack from a specifically crafted IPv6 packet. The packet must be sent from a local network segment. Only devices that have been explicitly configured to process IPv6 traffic are affected. Upon successful exploitation, the device may reload or be open to further exploitation.

Re:I hope they nail him to the wall!

[Anonymous Coward]

He obtained the information through an agreement with Cisco and ISS. Even when he says "I quit." he must continue to honor the agreement. So he's subject to at least lawsuit.

Since he posted an uncorrected vulnerability which could cause damage to Cisco and many of Cisco's clients then he falls under laws concerning computer security, break-ins, etc. He distributed how-to information on breaking into Cisco routers. So he's a criminal cracker.

Put the egotistical dickhead behind bars and throw away the key. We really can't permit nutballs like this to go free. He has no responsibility: he's a sociopath.

Death of teh Intarweb exaggerated, AGAIN

[gibmichaels]

Most tier 1 and 2 ISPs upgrade their code in a timely fashion. They're also on a mix of Cisco, Juniper, and Foundry (and I hear someone actually uses Extreme). Some third-rate companies or pretenders might have problems in a situation like this, but the effect has been greatly exaggerated.

The disclosure aspect is sad, but it's not like this is anything new. Might want to get the lawyer hooked up *after* you quit your job to release the paper, and *before* you head out to the conference. Don't expect any different behavior from companies until the next regime change...

Cisco IOS is tackier than we thought

[Animats]

After reading the slides, it's clear that IOS is tackier than I thought. Their approach to buffer overflow prevention involves magic values on the stack and periodic processes that check them. That's a containment effort for transient hardware errors and a debug tool, not a security measure.

Apparently buffer overflows within IOS aren't that hard to create, and so all the usual attack approaches can be used. That's the real story. And apparently IOS is a single-address-space unprotected OS, so anything can clobber anything. There's so much stuff in IOS now that there just has to be trouble.

Now I see why they're switching their larger routers to QNX, which is a protected-mode microkernel OS.

Gov't should have more oversight

[failedlogic]

I'm a non-IT, non-programmer type, so I'm really an outsider looking in.

In many press-releases and conferences and what-not, the U.S. Gov't always refers to the Internet as critical infrastructure. I agree it is: a lot of e-commerce, day trading, exchaning of new, etc takes place on it everyday.

Instead of spending time "investigating" people who might or might not be committing a crime on the Internet, would it not be a better use of resources to instead help make the Internet more secure? Fine, a lot of the internet works on equipment and IP of the private industry (a good part based in the U.S. too). Should the gov't not attempt to make law, something where companies must in X number of day issue patches for critical software (say 60 or 90 days, less is better)? What about establishing some sort of industry standard ISO-type stuff for computer security? Fines might not be a good idea if a patch is late, but something should be done. The threat of lawsuits is deterrrent enough for the industry but gov't should be more positively involved in this matter.

I'm all for the FBI doing their job: investigating and preventing crimes. The government should also try and involve itself and the industry for preventative and "patching" standards with-in the industry.

Is that the "proper channels" weren't at all interested in conveying the info to everyone- because it was bad for business.

At that point, you're left with two decisions- let it all blow up, or whistle blow.

Considering what I know of Michael (I worked with him for some time at one of his previous jobs- Michael, if you're seeing this, try to get in touch with me, you already know how...) he had only one- to whistle blow.

Re:The problem with that thinking is...

[mpapet]

Blowing up is not a -guaranteed- outcome in this scenario.

Even if the worst things really did happen, there would be the usual media hue and cry followed by some empty corporate-speak response followed by a government hearing or two and the whole thing would eventually die down.

IMHO That -is- a viable alternative. The corporation representatives dealing with the government representatives. That's "proper channels" communicating with each other. He needed to wait to get something similar in order, maybe have the EFF deliver it? ACLU? Certainly not what he did.

I wish him all the luck, because it's going to be a bumpy ride for a while.

Boo on Cisco

[Stumbles]

What it really boils down to is Cisco knows their code/firmware is about as well written as Microsoft windows and just about as secure. They just don't want everyone else to know about it.

Not really.

[Anonymous Coward]

He stole 5 documents, that were in national archives. He destroyed 3, but left two. It is possible that something of interest was on the 3, but according to all others, it was not. It sounds to me like somebody who was thinking of doing a cover-up of making a bad decision and decided against it.

In contrast, Nixon had ppl go out and do a break in. Then he and others did a massive cover-up and he would have gotten away with it except for deep throat. Regan traded guns to delay American hostage release a full year. Then there was a cover-up with a number of lies and of course RR saying the immortal words, of "I do not recall".

Now, you have a white house that outs a CIA agent by which all of her contacts are totally compromised. For what? an election again.


All of these are worse than somebody who aborted doing a cover-up of material that could prove embarrassing (but nothing criminal). However, I do think that he should do time for it (just as Nixon and Reagan should have done time, Rove should be shot for the traitor that he is, and GWB/Cheney should do time for aiding and comforting the enemy).

The world inside out?

[gcantallopsr]

Cisco should be punished, not Lynn. This issue is a problem caused by Cisco to its customers.

OK, I'm not so naïve. I understand Cisco, their methods and their motivation... but I don't have to like it. And it's good to explain the truth to people.

And your proof of that is...?

[Anonymous Coward]

Second, it's Cisco's right to do what they want with his research, since he did *break the law* in order to release it ( decompiling code + license agreement -> ?=( ). Following your conscience (in a way that was by some reports rash and poorly thought out) does not necessarily give you immunity from the consequences of your action.

I don't believe you're in any position to know that given the nature of the information publically available. Now, Cisco did *contend* that this was the case, but we don't have *any* copies of the agreement(s) in question, nor do we know which, if any, he agreed to. That makes ALL the difference here.

FWIW, Lynn followed responsible disclosure practices and Cisco does not appear to have in this case, based on the representations made about the vulnerability by both parties. This is both patched and being actively exploited from what they've said; it SHOULD be made fully public, and I don't think they've done this at all. That pitiful advisory I saw on Bugtraq is so thin on details it just doesn't cut it.

What a freakin mess

[l0ungeb0y]

While Lynn did good work discovering this flaw I don't agree with his actions in the slightest. Cisco made the fix and released a patch in a timely fashion. Who is he to dictate how Cisco goes about announcing it? Is he the boss of Cisco because he found a flaw?

Granted, it would be advised to mark the patch as critical and give it some press. But is that required?

Personally, Lynn's the ultimate loser here. He stands to watch his career go straight down the shitter and for what? Some ego-centric power play? I don't think any corporation will want to bring him in at the risk of him pulling some stunt like this on them if he gets his nose bent out of joint.

And as to the FBI, they're just doing their job -- they got a complaint so they flat foot it a bit and check it out. I'm sure they'll bug out of it soon enough.

And while Cisco and ISS maybe playing hardball, I can understand why. The dude started a fire and they damn well sure want to stomp it out.

And it seems that both ISS and Cisco were willing to allow him to make this public disclosure -- they just wanted some PR guys their to do damage control and make sure their side was accurately reflected. But for whatever reason, Lynn would have none of that -- so he quit his job and gave them all a big F-U.

Personally, this guy sounds like a complete ass-hat and I question his real intentions here. There are many alternative ways he could have raised the issues he wanted to bring to bear.
Showing up at a black hat conference and giving a how to on this exploit was certainly never going to do anything more than harm Cisco.

What I want to know, is if Lynn really did want to help out, why he couldn't have set up a blog that merely discussed the abstract points of the security update and explain why the patch was critical and then post to slashdot or other IT news site to generate the publicity?

If he'd simply cast his ego aside and thought things through a bit better, and worked with all parties involved he'd probably still have a job and the message would have gone out in a far more positive manner.

Lynn is morally guilty

[AB3A]

Sure, free speech and all that... He did nothing illegal, but he should have put a bit more thought in to the whys and hows of the release.

First, nobody has yet attacked via this vector. There are no examples of concept code out there. Had someone exploited this vector, then it makes sense to educate the public that it exists and why. Until then, I think the moral thing would be to STFU. Cisco has a right to be angry (though not to use heavy-handed tactics).

Second, I would find his position to be much more moral if he had given this information anonymously to the conference, or some other such forum. The fact that he put his name on it smacks of a grab for infamy. His goals, if they were truly altruistic, should not have included his identity because that was irrelevant to his presentation.

He's no hero in my book. I'll give him credit for trying to do the right thing, but I still see his actions as ultimately counterproductive.

Of most of the exploits we have seen thus far, the vast majority have been script kiddies. Very few worms and viruses have used undocumented attack vectors. Now, that doesn't mean that All of them are like this, but it does mean that there is some security to be had through obscurity.

Given that IOS is entirely proprietary, it would be wise to give Cisco plenty of notice of the vulnerability and let them patch the problem first. After all, you probably don't have access to the IOS software sources. Patching your own routers with just the information presented by Lynn would be a monumental achievement. I doubt you or most slashdot readers could do it in a timely fashion.

I am not defending Cisco's attempt to sweep this under the rug. However, computer networks are a fragile technology built on a thin veneer of civilization. Telling people how to tear it apart before we can even take measures to reinforce it is nothing less than irresponsible.

I'd have to think long and hard before hiring a guy like Lynn.

Undoable

[Anonymous Coward]

Perhaps if you write her, she will get Cisco to ask the FBI to lay off the good researcher (ask her to have Cisco "take it all back").

The FBI doesn't work like that. They're much like a wind-up toy in that respect: once you turn that key, there's no stopping them until they run themselves out.

What's set in motion is unstoppable at this point.

FBI Involvement

[omb]

This is the most stupid use of Federal Intelligence and policeing ever;

One must assume that the politicised senior
executives have not the wit to understand the
benefit of timely disclosure of security exploits
and the fact that the black hats will know without
public fanfare.

The FBI and the DHS have a job that SLOULD fully
occupy them, find Ussama bin Laden, and kill him.
When they have done that they can turn to lesser
priorities.

Cisco are Vulnerable

[GC]

By the title I mean, not necessarily in their technical sense, but they are vulnerable through market forces.

Let's face it, companies pay through the nose for Cisco kit, mostly simply through conitnuity purchasing.

Yes, the Cisco kit generally performs as advertised, but I doubt that that has ever influenced someone who had the responsibility for buying the kit.

The market is crying out for a network supplier who can provide the goods & functionality of the Cisco kit for what is deservedly a fraction of the price that Cisco charge.

Cisco have a terrible support policy, unless you purchase your particular item with support you're knackered.

Compare that to even Microsoft, who at least have a larve knowledge base freely available, have reviewed their security updates and made their OS secure as any closed OS can become.

Cisco lag behind in their field far further than any of the other companies in IT.

Their strategy? Invoke achievablie certification which gains advocates for their products. Sign those advocates up to virtual-non-disclosure and reap the benefits.

Plame and her husband went swimming with sharks

[Anonymous Coward]

She helped land her husband the job about investigating whether or not Saddam tried to get nuclear materials (and if you think Saddam wasn't trying to get nuclear materials just Google Osirik. And who's that with Saddam? Why it's the leader of the "Coalition of the Bribed"...)

Then, after getting home, Joe Wilson goes on the attack against Bush.

Just like in the summer before the election that "anonymous" CIA published a book bashing Bush.

That's two senior CIA agents that played in politics against a sitting President, trying to stymie his reelection bid.

The CIA is lucky Bush didn't bulldoze the place. IMO the Plame "outing" was a warning shot - and almost certainly a perfectly legal if nasty one. Bitch all you want, but if your tried to bring down your workplace CEO or President in your company's next board meeting, you'd be in dip shit too.

Congress shall make no law ... abridging the freedom of speech, or of the press.

He's being investigated for what, now? Talking?

Shouting fire in a crowded theater... Next!

Really... you guys are going to have to try a LITTLE bit harder now that the highest court in the land has interpreted "public use" to mean "private office complex." The US Constitution is nothing more than a keepsake these days. Wake up and smell the freedom fries, they don't actually abide by the thing any longer.

welcome to the ussr of old

[suezz]

what a crock of shit - cisco should be thanking this guy for finding their bug in the first place.

doesn't the FBI have anything better to do like find Osama bin laden and their followers.

One other thing is why didn't all their ccna's or whatever find the bug? Aren't they certified?
My snort logs still pick up unpatched cisco routers at work all the time.

Re:In Soviet Russia ... router 0wns YOU

[UnapprovedThought]

Maybe the GP made the mistake of reading the story title? You can sort of begin to see a hint there how cooperating with Cisco might not always produce the results you wanted. The GP is spared from going to room 101 -- this time.

Anyhow, from my limited understanding, Cisco claimed that the exploit had already been patched since April, the patch supplied to customers and they deny that it was ever anything approaching a critical issue. The civil charges were settled, supposedly. So, then, if the original complaint was satisfied, who is the damaged party that they are investigating him on behalf of? Tick. Tock. But wait... the plot thickens.

Quoting him from the wired article:

"I was really mad at ISS before and now I'm extremely disappointed," Lynn told Wired News. "At this point, they're just trying to milk it for punitive damages. We already had a standing agreement, and now they're trying to attack me in some other way."

Extremely disappointed? Didn't he mean to say double-plus unappointed? That is, if he actually exists. I did not claim that he ever existed, by the way, just in case all archives of his existence suddenly disappear.

Lynn's document for download

[Anonymous Coward]

I disagree with CISCO's position and believe that every effort should be made to release this information. The more it becomes available, the sooner CISCO will fix the problem.

Wow, if I got it right this guy intentionally DESTROYED DOCUMENTS TAKEN FROM YOUR COUNTRYS ARCHIVE and he will GET BACK his security clearance after a while?

Looks like you're fucked, basically.

The other problem is

[NewToNix]

that I seem to detect a bit of yellow showing through that particular Black Hat.

Not a good sign... it requires gutsy people to push the envelope, in order for progress to occur.

Lynn showed what he's made off... and so did Cisco and Black Hat.

All in all, not a good day for anyone... except maybe admins that now know a bit more about their Cisco system then they did before.

I hope...

There is no sig like the old sig, so this is it.

How the POTUS could be killed.

[the_raptor]

This is a plan on how someone could kill the President of a United States. Wait until the POTUS is known to be inside 1600 Pensylvania Av then either A) Detonate a Truck filled with high explosive outside the oval office, or B) Hijack an airliner and crash it into the building.

Wow the FBI better lock me up for giving away this tottally non-obvious information to the terrorists. Hell I even gave them the address and everything.

Or maybe talking about obvious and non-specific information with the intent to prevent such an attack occuring is something people should be rewarded for?

filing a false police report

[mabhatter654]

filing a false police report!

That's what Cisco is doing here.. YES, they ARE using the FBI and "national security" as a cover for a personal vendetta.

What they're basically asking is because their software is insecure, they've not reported the info to the public for 4 months, but this guy did, they want the FBI to "investigate" until they FIND something to charge him with. Because and FBI investigation is punishement in and of itself... It should take no more than 5 minutes for the FBI to realize this is a open & shut whistleblower case and Cisco is wasting their time. Unfortunately, the FBI doesn't care about what a person's RIGHTS are, only if they can find some crime you committed.. after all, they'll have to find something to justify spending the $100k's they've already spent!!! Going back to Cisco and fining them for a "false" police report almost never happens.

You never had a right to free speech...

[Vryl]

The oft quoted example of shouting 'fire' in a theatre...

Or defaming people, ie 'hackstraw is a paedophile', etc

Not that I disagree with your presumed sentiment. Cisco *are* out of order here.
