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."

    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.

      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!

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.

    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.

    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.
