Evolve or Die
http://packetstormsecurity.org/ surely some people would have learned some lessons.
Never trust Windows Server, and as the saying goes, any Linux or BSD is good as long as you harden it; however should you be a lazy system administrator as I am sure there are plenty frequenters to
/. who are entirely that; then one has no rights being a system administrator in the first place. -
If using PHP5, change max_input_time
I agree with others, this is not a Microsoft issue, it's an issue for all sysadmins.
Anyway, from http://packetstormsecurity.org/files/108209/n.runs-SA-2011.004.txt is this helpful bit to reduce your susceptibility to attack, if you're using PHP:
The maximal POST request size is typically limited to 8 MB, which when
filled with a set of multi-collisions would consume about four hours of
CPU time on an i7 core. Luckily, this time can not be exhausted because
it is limited by the max_input_time (default configuration: -1,
unlimited), Ubuntu and several BSDs: 60 seconds) configuration
parameter. If the max_input_time parameter is set to -1 (theoretically:
unlimited), it is bound by the max_execution_time configuration
parameter (default value: 30). -
Technical Background
Just to make it clear - this affects a whole lot of systems and is based on a flaw in the design of hash-tables:
http://packetstormsecurity.org/files/108209/n.runs-SA-2011.004.txt
Basically you can pre-calculate a huge set of POST parameter names which will all be hashed to the same value. Since these are stored in a hash-map by most web-frameworks - this will lead to a o(n) lookup time instead of a o(1) lookup time, when testing the hash-map for a given parameter name.
This will max out your cpu quite quickly depending on how many lookups you perform per request.Since the attack has "script kiddie" difficulty, this needs to be patched ASAP by all vendors

Re:No Mistake
Heh, I remember using Computer Narcotics back in the 90's. At the very least there's a nice placebo effect. The guy who wrote CN was actually blind and had a BBS. Cool guy.
It's still on some shareware sites, but you need dosbox to run it on your modern win/mac/linux computer.

It will probably be a honey pot. Eitherway Cult of the Dead Cow or pulltheplug have already r00ted the target in 60 seconds.

Who said Linux is impervious to malware?
I could knit-pick your grammar, but is this overall claim based in empirical research? Linux certainly has it's flaws and while it's not susceptible to WINDOWS malware, it certainly is to a variety of others. Perhaps take a look at http://insecure.org/ or http://www.packetstormsecurity.org/. Both of these sites maintain lists of exploits to various version of Linux and many other types of GNU software as well. Rootkits most generally fall into the realm of 'malware' and once you've got root, baby, you've got the world.

Re:So ...
There's actually nine rootkits out there for Linux?
The rootkits in question are:
- adore-ng 0.56
- eNYeLKM 1.2
- sk2rc2
- superkit
- Phalanx b6
- mood-nt 2.3
- override
- Sebek 3.2.0b
- hideme.vfs
Some of them are in the wild an some are just for research. For more information, I would check out this page.

Exploit?
Is there some sort of exploit code I can run to check if my system is vulnerable? I tried to find some online, but I only came up with some code for SCO Unix and some code that is so horrendously long that I don't dare running it for fear it might do something I don't want to happen on my system.

The real Reason Gopher died.
It's really very simple, but it's a small technical detail that seems minor at first sight.
When you connect to a Gopher server it waits for you to send a string (just like HTML) this string is the name of the item you want. HTML is almost the same, except you put a command (GET, POST...) in front of it. This is not important because you can easily run an HTTP site with just GETs.
The difference is that Gopher immediately gives you the file, whereas http gives you a status code and file type then the file.
Why is this important? Well it's not, if the world is perfect, but in the real world things change so the "selector" that was valid yesterday and pointed to an image might not be valid today. But the server doesn't know it used to point to an image so it goes and returns the main site page which isn't an image. At this point the client throws a tantrum.
This means that the only links you can reasonably do are to your own site or to the root of someone else's, no deeplinking, no "intergophers". OTOH, because http returns the status and type there are lots of options if things move, but none of them are a client program crash (normally!). This also applies to links you make, ie no bookmarks, so you don't remember where that important document was on the gopher server, but you a (safe) bookmark directly to the http location.
HTTP wins, html comes along for the ride, Ooops!.

Prior art: L0pht antisniff from 1999?
Looking at the article, (and having skimmed but not read all of the patent), isn't AntiSniff (released by DilDog of L0pht in 1999) using this technique? (Slashdot article, Aug '99)

Re:Linux patches?I invite you to investigate this site which holds no immediate bias in it's reporting of security advisories, patches, problems and exploits. Look at the average turnaround time for patches, fixes, and responses to security problems. You will find out that Microsoft isn't as bad as everyone likes to pretend it is, nor is it's flagship Windows OS. Also to, I find it ironic that whenever someone points out a problem that affects Linux, people are like "But that's not the OS, it's (insert kernel module, driver, app, whatever) that is (insert special circumstance here).", but when it's Microsoft, they're all lumped together as "OMGz! Windoze h4x!". This includes vulnerabilities in Word, and Excel (and something else from the Office Suite, can't remember though atm), and additionally mentions Exchange. Exchange runs on a server platform, but ok, I'm not going to get into semantics on that (I assume they meant Outlook, though even if it was Exchange, it's still a fix, or at least an attempt at one).
I am the first to admit that Microsoft has problems with security, but it's a problem that plagues the entire industry. Linux, Unix, Windows, Mac, websites, forms, applications, EVERYTHING. It's a problem in how the industry approaches security. It goes far beyond Microsoft. The entire industry has this "Get it working now, patch it later" mentality. It's the "Default Allow" instead of "Default Deny" approach. There is NO reason Buffer Overflow attacks should work... EVER. Period. How hard is it to check your buffers, and make sure you're handling them properly? Very sloppy. Microsoft certainly isn't the best, but they're far from the worst. Don't believe me? Check that website, and all the security advisories for the past few years, and you will notice and interesting trend.
-
Flaw? Patched? Microsoft? Linux?While I agree, very good response on getting this patched, and Linux does seem to have a better overall response time to patch needs, they're needing it more and more these days.
I find it pretty interesting that security advisories over the last several months have been on primarily non-MS platforms. Mac, Linux, Solaris, etc. have had many more security advisories than MS Windows has had to endure, and Microsoft, while certainly not leading that pack for response time, also isn't dead last. I invite you all to check This site which is April's list of security advisories. I remember seeing a review on security a short time ago dealing with response time from various OS Vendors, and while MS wasn't leading the pack in anything, they weren't dead last in anything either.
I personally think Linux has a lot of potential, and is a pretty decent OS. But it's not ready for primetime just because of the average user. Windows has a tough enough time with security because of the user (let's face it, 90% of problems are the user's fault). Sure, exploits exist, but you have to DO something. Users don't download patches. Users click on anything with an OK box. Same applies here. How many "users" running Linux are even going to know about this vulnerability, let alone patch it. Ok, if they've auto-updates on, perhaps they will fetch it in their next batch? In which case, good, and kudos to the distro for making that part painless for the user.
I've always wondered about Linux's wifi security, but that was primarily because of having to wrap up the driver of most wifi cards. Just seemed to me like a door just begging to be broken down. Apparently I wasn't the only one.

USS Yorktown & Blue Ridge
I'm sure we all remember how well things went for the U.S.S. Yorktown; an Aegis Class missile destroyer that ended up dead in the water after a crew member entered a zero into a database. Obviously, this was caused by the fact that the Yorktown's control software was of a really bad design. Critical systems should have never been so tightly linked that a failure in one area would cause a cascading failure across the ship. Still, it raised a lot of questions about the wisdom of using consumer software for life and death situations.
Two years after that, the Navy had still not learned their lesson. The flagship of the seventh fleet, the USS Blue Ridge, was deployed in 1999 with Windows-based Command and Control systems. The result? The ship was infected with the Melissa Macro Virus. (Source - Section 12.4)
I'm sorry, but when you're taking men into combat, you want equipment that has been designed to do what needs to be done, not pretty features that let the GIs open their email attachments. There's a reason why the current military setup in the US is for the crew to have their own laptops for personal use. Using a consumer OS in a battle-critical system is nothing but a recipe for disaster. It's too bad that Her Majesty's Navy has failed to learn from the mistakes of others. -

Re:You don't see the problem.
That's a pretty pitiful attempt at a dodge.
An operating system (OS) is a software program that manages the hardware and software resources of a computer. A key component of system software, the OS performs basic tasks, such as controlling and allocating memory, prioritizing the processing of instructions, controlling input and output devices, facilitating networking, and managing files.
...Security
Security as it pertains to the operating system is the ability to authenticate users prior to access, categorize the level of access the user has, and limit access based on a policy placed by administration. Typically an operating system offers (hosts) various services to other network computers and users. These services are usually provided through ports or numbered access points beyond the operating systems network address. Typically services include offerings such as file sharing, print services, email, web sites, and file transfer protocols.
At the front line of security are hardware devices known as firewalls. At the operating system level there are various software firewalls. A software firewall is configured to allow or deny traffic to a service running on top of the operating system. Therefore one can install and be running an insecure service, such as telnet or ftp, and not have to be threatened by a security breach because the firewall would deny all traffic trying to connect to the service on that port.
-- Operating System, WikipediaDodge? I simply asked you to inform yourself of the basic definitions of the discussion--something you should have already familiarized yourself with if you want to have a productive discussion. An anti-virus clearly plays no role in the purpose of an OS, nor is it a key component in building a secure OS--unless perhaps you have a different definition of an OS that you'd like to share?
There's a hell of a lot of people on Slashdot who seem to think it can, however.
Are you familiar with ARGUMENTUM AD NUMERAM? You can't seem to build a logically sound argument as to why not packaging an anti-virus with Vista would make the OS inherently less secure. OS X does not come with a pre-packaged AV, nor do most Linux distros, FreeBSD, NetBSD, Solaris, nor pretty much all other OSes. The fact that it is something that would be packaged along side the operating system suggests that it's not an integral part of the OS or OS security.
So what is the definition of a secure operating system ? What OSes meet it ? What OSes don't ?
There's no such thing as a perfectly secure OS, but there are relatively secure OS's--these are operating systems that are secure by design (rational security policies), have relatively few exploitable bugs (few system vulnerabilities), and have secure default configurations (easy to secure by the average user). This doesn't entail protecting the user from himself. If an AV detects a virus, then chances are the OS has already been infected. If anything, AV's encourage users to be stupid about what they download since they think the AV will pick up all viruses and they will be more likely to proceed downloading and executing suspicious attachments. You can't build a foolproof system, the trick is to educate the user so they don't act foolishly.

Is this the same thing as this
Unfortunately you left out the link, so I don't know what "this" is supposed to be. But from your description ...It is a buffer overflow on IE but on Firefox it just completely freezes up the browser/potentially opens tons of windows.
No, it isn't anything like that. I'll find the direct link to the "exploit" (unfortunately and non-coincidentally I've erased my visit history since then) but it's just few links from the FA. So here's the so-called exploit. It serves up as plain text so it's safe. -
This isn't a problem.
There is no security breach involved here at all. It's not even a very bad bug. Clicking an infected link (as I've done) doesn't crash your browser, it doesn't keep it from reopening, it doesn't cause a buffer overflow. All it does is make Firefox take a unusually long time to open the next time. Admittedly, an inexperienced or impatient person might think this is a crash , but it's really not.
P.S. The original code is found at http://packetstormsecurity.org/0512-exploits/firef ox-1.5-buffer-overflow.txt (note that this is a text file. It needs to be changed to HTML and have a link clicked to work.)

What about kernel level rootkits such as Knark?

The ping of Death
When I was 13, I used to be in a hacking group known as ViRii on Undernet.
Around that time (early to mid 90s), there were several hacker group wars going on Undernet. I remember the +++ATH0 exploit among many dozens of other exploits at the time.
In mIRC, you could do: //raw NOTICE VictimsNick : $+ $chr(1) $+ PING +++ATH0 $+ $chr(1)
And their modem would hangup/reset.
There was a guy name VallaH i knew in my hacker group. He was the one who original discovered The Ping of Death in Windows 95. He also wrote jolt.c and many others. He was among the first people to find remote exploits in Windows 95. (Microsoft actually hired him that year to work on Windows NT network security, I was quite jealous at the time). The funny thing is, he only designed it to nuke Windows, but it also worked on early Linux 2.0 kernels, solaris and mac (since they all used mainly the same BSD tcpip code i'm guessing)
Vallah later lost his job at Microsoft due to his hacking past/present i'm guessing.
Quoted from this archived email:
"My friend, I will call him Vallah. Lost his job at Microsoft working on network interoperability(sp?) for Windows 2000 when the FBI showed up with a warrent for the files on his machine at work. He has still not been charged with anything and most likely wont be... again, mainly becuase he hasn't done anything. Guilty by association and an infamous past."
I wasnt a hacker myself, more of a wannabe (script kiddie) hacker. I mainly just nuked other people on IRC and did channel takeovers, etc.. The fun lasted until I was around 15 (i'm now 22). Alot of the more serious hackers I was associated with ended up getting caught by the FBI. I have literally hundreds of old hacking stories from my early days with IRC. (Note that i'm now into computer security, not destructive behaviours like hacking).
I have one other story about a guy I knew around my age by the name of XaiL. He was 13 at the time, and he hacked nasa.gov using an old phf exploit. I used to talk to him on the phone long distance, he was a funny guy, sounded like a girl, he hadn't even started puberty by the sound of his voice. I do admit that the only hacking I ever did was using this same phf technique, long since patched. I'm not proud of my early days as a destructive script kiddie hacker, but at the time, it was so much fun.
I also had a very small part in writing the mIRC script known as 7th Sphere (my code was included in the last release, version 3.0, not the previous 2.666). At the time it was a hugely popular "war" script used by script kiddies to nuke, flood, do channel takeovers and many other evil deeds on IRC servers. It came with programs made by Rhad using VB, most notably was "click.exe", a program that let you instantly "nuke" any victim. If you do a google search for click.exe or "Rhadware", you will get the idea of how evil his programs were. -

With the passing of defcon and black hat this month, a lot of new security vunerabilities have been released, and all of the 'script kiddies' are eager to try them out. The best thing to do is make sure all your software is up to date, and get familiar with the new vunerabilities that are out so you can protect yourself.
As far as reporting them, you could try all day and not be able to report all of them, and even if you did, they're most likely attacking from someone else's vunerable machine. The only thing you can really do is watch out for anyone who's aggressivly attacking you (i.e. one person who's running lots of attacks on you trying desperately to break into your machine at any cost), and report those ones, or if you can find a way to contact that person, tell them to stop before you report them to their isp and/or authorities, this will usually scare most people off.
Once you do start paying some decent attention to security releases, a lot of these stupid things people try won't surprise you, like the ssh root attempt is because some tool came out recently that just scans netblocks for anyone running ssh and try's logging in as two different users with no password, root being one of them. If your not familiar with where to find security releases, here's some good places to start:

Re:How to spot what is happening
Another good rootkit checker, which seems to have a more active development cycle, is Rootkit Hunter. Here's a Newsforge article on it, with a few more details.
A few other comments:
Virus scanners won't help on jot against a custom hack (as Valve found out, for instance). They can be helpful, but don't put full reliance on them.
Running an Intrustion Detection/Prevention System such as Snort, Samhain, Prelude, etc. will help you manage the monitoring side of things; more than a few machines becomes a pain without additional help. Also take a look centralising all your logs on a syslogng server or something similar, if you don't already (note that there are various solutions out there to get Windows boxes to log to a syslog server).
A honeypot may distract the hacker from your production servers for long enough for you to identify that there's a problem.
Also take a look at "HoneyTokens": specifically created database records that trigger alarms if they're accessed - usually high profile fictious targets that would make excellent trophy hacks - there's more info on this over at SecurityFocus.
If you suspect that a machine has been compromised, as other have said, the ONLY WAY TO BE SURE is to rebuild the box from scratch. While this may be a real pain, hopefully it'll help you get the procedures in place to make this as painless as possible, so it's not all bad.
Perform security audits/pentests every now and again. Tools like Nessus help: here's a good series on using Nessus (part 2, part 3).
Get familiar with security tools such as the top 75 recommendations at Insecure.org (home of Nmap).
Remember that security is a PROCESS, so be thorough; get an entire plan together and cover all the bases that you can, taking special care to identify and cover the weak points. Your company's security is only as good as its weakest link; for instance, priviledge escalation of weak user account passwords is a good one.
Read SecurityFocus, PacketStorm, CERT and the like, and try to get involved in their communities; they can be invaluable! They're also got a lot of good tutorials, such as how to lock down Apache, IIS; securing PHP, ASP; etc. -
Re:How to tell and Fixes
According to lots of people you don't know what you are talking about.
There are two issues here and the IE compromise that infected IIS servers are serving to browsers is an UNPATCHED ADODB.STREAM bug coupled with an UNPATCHED CODE IN CHM FILES EXECUTING IN THE LOCAL SECURITY ZONE bug. "patch it with MS04-11" really doesn't cut it.
You may wish to make sure MS04-013 is installed and look at this for some registry settings which supposedly fix the exploit. BUT. As others have said the only real fix is to use a different browser as it is not 100% guaranteed that these are the unpatched IE flaws which are being exploited in all cases. -
Damnit...Why hasn't anyone in Washington ever read the mathematical proof that such a system will make us LESS secure?
:/
It should be somewhere on Bruce Schneier's personal website, in a fairly recent edition of the Crypto-Gram newsletter, IIRC.
Oh well, seems like a perfect time to quote this little tidbit that Packet Storm has had on a sidebar for quite a while now:
Call Your Reps For Free
A toll free number has been set up for the US Senate and Congress at +1-800-839-5276. They immediately answer "Capitol" and will happily transfer you to your congressional representatives. Call during business hours and feel free to speak your mind, asking them not to expand the Patriot act, repeal the DMCA, push through donotcall.gov, etc.

Tips...
#1: Learn to love the hourglass icon, 'cos you're going to be seeing a lot of it from now on.
#2: Get used to extension-based file typing, and remember that not everything ending in .scr is a screensaver.
#3: Develop a healthy sense of paranoia - they are out to get you, especially the ones that send e-mail with subjects like "Hello"
#4: Give thanks for the guys who develop Win32 ports of Perl, Python, Apache etc because they are the thin geek line that stands between you and Visual Basic, Windows Scripting Host and (ugh) Internet Information Services.
#5: Get hold of Mozilla, Evolution, and OpenOffice. Man cannot live on IE, Outlook and Office alone.
#6: Head on over to PacketStorm and stock up on some local admin exploits and the excellent Cain&Abel so you can take back the rights these no-good dirt-farming MCSE's are going to try to take away from you.
That should get you started. -
Re:Know your enemy, then attack.
My guess is they will create another fud attack by studying its weaknesses and then pay someone like the Gartner group to set for the same results under a limited condition and boom. Instand fud, WIndows2k3 can do this but Linux can't.
This could be easily accomplished by visiting packetstorm. They wouldn't even have to set up the lab.
Of course, packetstorm works both ways.

Re:Not good enough.
Go visit Packet Storm. It's a pretty good site to grab admin tools. And a good place to read about what exploits you need to keep your eyes open for.
Not sure how much you'll pick up for just your webserver, but it's a good starting point to pick up from.

Re:Now all we need
Now all we need is for someone to hurry up and port some spyware to the Mac, so this product will have something useful to do.
It is not so funny as it may sound. This is exactly my attitude when I installed Debian stable release few years ago and never minded checking security updates. I laughed at my Windows-using friends every time there was a new worm or virus, telling them that it's not fair that GNU/Linux is not supported by all of this malware, until someone exploited my old bind buffer overflow and installed a kernel level rootkit.
Remember that Darwin, the base of Mac OS X, is based on FreeBSD. chkrootkit, a tool to locally check for signs of a rootkit, is constantly tested on FreeBSD 2.2.x, 3.x and 4.x, not without a reason.
Read the paper Attacking FreeBSD with Kernel Modules: The System Call Approach written by pragmatic/THC on June 1999 to have some idea on how well those issues were understood three and a half years ago. This is only one paper, the first thing about FreeBSD rootkits I just found.
So, of course it's funny what you said, of course your Mac is indeed much more secure than an average Wintel box out there, but it doesn't mean there's no spyware. Your Mac is not a toy, it's a powerful Unix box under the hood, which may mean that it's harder to exploit than Windows box, but it also means that when it's exploited, it's probably easier to write and install spyware there (like a simple kernel module which would intercept read syscall, for example). Never forget about that.

Re:Snosoft security...
Um, no. Many operating systems were affected by that, including OpenBSD, FreeBSD, NetBSD, and Linux. Observe.

Packetstorm.....
Yeah this really is depressing. However, another site I like in case any of you are unaware is Packetstorm. I like it a lot and so far it hasn't sold out.

crypto.radiusnet.net is a jokeHi all,
I think we'll all find that this ends up being less of a problem than it seems to be, and certainly one unworthy of Declan's attention. The first thing to consider is that of the couple of security/crypto archives out there (Wiretapped, munitions.vipul.net, the old zedz.net site, Packetstorm), the crypto.radiusnet.net one is the only one of the group that is out of date, disorganised and discourages mirroring. Look over the site, and you'll see what I mean. The second thing to consider is that (as another poster has already mentioned) PGPi.org has the explicitly freeware versions of the software available on a number of mirrors worldwide, and does not appear to have been made a target here.
Conspiracy theories aside, if they were mirroring commercial versions of the product, NAI is well within their rights to pursue them, and I'm sure the other legitimate crypto/security archive sites will be glad to see crypto.radiusnet.net stop sullying their good names by association.
