Microsoft Confirms Update-Linked BSODs Required Compromised Machines
Trailrunner7 writes "Microsoft on Thursday confirmed that the blue screen of death issues that affected a slew of users after the latest batch of Patch Tuesday updates is the result of an existing infection by the Alureon rootkit. There was widespread speculation after the patch release that simply installing the MS10-015 update was causing the BSOD condition on some Windows 32-bit machines. However, Microsoft said at the time this was not the case and started an investigation into the problem. In an advisory released Thursday, the company said that it now was confident that the restart problem is being caused by the Alureon rootkit." That seems a harsh way to find out that your Windows machine has been rooted.
Now, I wonder who the first poster is going to be to demand Microsoft test their patches for compatibility with viruses and malware?
Yeah a BSOD is harsh, but finding your bank account mysteriously drained of funds is more harsh. At least they found out.

The bluescreen may be painful, but it is far less painful than having your information stolen by criminals. Assuming of course the people who own the machines are savvy enough to properly install their firewalls and virus protection next time.
I read the internet for the articles.
Microsoft needs to start testing against all known (and future) viruses and other malware. It just makes sense.
I judt got a nre Kinesis keybiartf so please excusr ant egregiou typos.
I think that this approach should become the industry standard for retaliation against malware. What better way to force complacent users to cleanup their machines than to disable them? Less botnets = more bandwidth for the rest of us.
Huh? I thought Netcraft confirmed that BSD was dead. Oh waaaiiiitttt... BSOD
Ok nevermind
That seems a harsh way to find out that your Windows machine has been rooted.
Or a good way, as it will force people to find a way to fix it. Who knows, maybe it will even teach some people some things about the dangers of rootkits.
That seems a harsh way to find out that your Windows machine has been rooted.
Don't worry, I'm sure the author(s) of the rootkit released a patch within 24 hours that automatically updated the infected machines to make the rootkit "compatible" with the security update.
The malware has been updated so that it won't cause a crash.

I wouldn't be surprised if the rootkit authors were at work on a patch for this BSOD. They will of course send it out via auto-update.
Sounds like we found the explanation for the Norfolk issue:

What do you want? Some cuddling before breaking the bad news?
"Sweety.. you got rooted" .. as it goes in the _wrong_ hole.

There are plenty of people who think that tracking down all the machines in these botnets and disabling them is a reasonable way of dealing with the problem.
So is Microsoft rushing out an update to their Malicious Software Removal Tool to clean up this rootkit?
Oh, say does that Star-Spangled Banner entwine / The myrtle of Venus with Bacchus's vine?
I really do wish it was that simple.
The simple fact of the matter is that even with all the security turned on, even with all the updates being installed automatically you still can't avoid the odd rootkit. And there are several modern rootkits which are really hard to spot - most AV packages won't prevent them and they don't take over the machine to the point where you start to think "hang on a minute..... there's something wrong here".
"Its better they find out this way, than not at all" is not the correct reaction to this. This BOSD is going to happen to the layman a lot more frequently than a tech person. When a BSOD happens to a layman, they don't record the stop code and look it up to see what the error is. The layman will just take it to geeksquad/local tech kid/vendor tech support and say fix this its broken. They wont realize their machine was compromised. They wont change their computing habits so that their machines don't get infected in the future.
Assuming that the affected users will clean up their systems and become more secure is wishful thinking.
However (in a perfect world), if MS validated the files before patching/updating them, the user could be warned of their infection before their machine gets trashed. Maybe an error message saying "We detect that your machine is infected with a rootkit, all of your personal information is in danger of being stolen. Please install a firewall/update your browser/ run your AV". That way, instead of confusion and anger from a BSOD, the user will be educated and possibly secure their system.
Really? I run mostly windows systems and haven't gotten a virus, rootkit, or other miscellaneous malware in years. It really is their own damn fault. But then, they're the same people who complain about having to give their programs permissions as administrators on Windows, but not OSX or Linux ...

[A Microsoft representative comes to a System Admin's place of work for a little meeting.]
MR: Thanks for making time to meet with me.
SA: No problem. So what's this all about?
MR: I don't know how to say this, but it seems that you... well you aren't entirely in control of your systems.
SA: You mean you're selling a new management tool?
MR: No, no nothing like that. It's just that there are certain things... Well let's say there are things about your system that you don't know that you really ought to be aware of.
SA: Oh, I see. You mean like undocumented registry settings, or DLLS or stuff like that.
MR: Well, sure. Technically you *could* describe it that way. It's only....
SA: Only what? How would *you* describe it.
MR: *sigh*. OK. Some Chinese hacker working for the Russian mob has been using you as his bitch.
Post may contain irony: discontinue use if experiencing mood swings, nausea or elevated blood pressure.
I'm not. They probably wipe and reinstall all their lab machines every time they test.
*sigh* back to work...
And I mean that sincerely. Please BSOD more botnets.

But that would break Alureon! Is an update available for it?

Virus:Win32/Alureon.A Definition: 1.69.77.0 Released: Oct 23, 2009
This was a zero-day exploit that the virus writers didn't know anything about.
They got the patch out as quickly as they could.
Is a value in and of itself. I have even more sympathy for those who have another rootkit, and have yet to find out, than I do for those who had a BSOD which caused them to either a) stop using their computer entirely and reformat or b) fix the BSOD and rootkit. Actually I have plenty of sympathy for both since I don't use Windows at all.
48 hours ago I was notified of a laptop with a rootkit.
And I can tell you now, that laptop wasn't running slowly.
It wasn't redirecting web requests.
It wasn't doing any of the things you might associate with rootkits. Yet replacing the AV with an alternate product and the alternate product detected several real issues.
Frankly, if I hadn't been notified by our bank (whose security company had managed to get a site shutdown and get a list of all potentially compromised accounts) I would never have had a clue. I concede that the user had admin privs on their laptop but I'm given to understand that even that isn't a huge barrier to a lot of modern rootkits. Thank Christ the bank in question doesn't allow you to do anything without the use of a separate security device they ship you.
Talk about a rock and a hard place. I can't trust the laptop at all, and it was infected while running a regularly-updated copy of Symantec AV Enterprise which suggests I can't necessarily rely on AV software to do what it says on the tin. Windows is obviously a lost cause unless I want to spend the rest of my live playing whack-a-mole yet I don't think the Powers that Be will stomach a move to Linux (even though most of them haven't used Windows-specific software in years).
Answers on the back of a postcard....
and haven't gotten a virus, rootkit, or other miscellaneous malware in years. ... that made itself known.
For large sets, this will be our guide even unto death, for the LORD will work for each type of data it is applied to...
All you need to do is verify that the files on the drive are the files released by the vendor(s). An extra step would be to make sure that they're the most recently patched versions as well.
That can be done with a bootable Linux CD and a list of the various files, their locations and different checksums of each of them.
Anything that isn't on that list is suspect and can be quarantined.
The advantage of a system like that is that it is easy to use to spot even unknown rootkits.
With several different anti-malware solutions. (Including but not limited to ESET, NOD32, MS, Symantec, and occassionally Spybot/Hijackthis/etc), nor shown entries in autoruns/procexp/etc, or the ocassional outbound-traffic-analysis.
They can be pretty hard to detect, but one that evades all of that is kinda magical.

Doesn't it work?
That seems a harsh way to find out that your Windows machine has been rooted.
I don't know about anyone else, but I would think that any way you find out your machine is rooted is going to be harsh. Sure, the not booting thing is annoying (still don't know why Windows or Intel/AMD chpsets don't support a Target Disk Mode for events like this), but finding out that someone else has had free reign over your machine for who knows how long (whether it is currently booting or not) is a harsh reality.
That's pretty much the case for the labs. We roll out updates internally first to give them a bit of a bash to watch out for issues, but 30k+ systems is not the same as a worldwide launch. Additionally, there aren't really that many user-grade XP systems left here, for obvious reasons.
Use the tools provided (firewall, AV, security zones, certificates for any secure sites you build for your intranet, etc), don't do dodgy shit on your box, and you won't get rooted.
In the past, I've had Windows boxes rooted, I've also had linux boxes rooted (via sendmail, DNS, etc). Since maintaining/securing them (even half-arsed), I haven't had a problem in the past 10 years.
Hint: "dodgy shit" includes installing "free" shit from untrusted sources.
I run: Windows, OS X, Linux, FreeBSD. Just because you have a hammer, doesn't mean everything is a nail.
Symantec is shit. Users should not have admin on business machines. They should also not be going out via unfiltered internet connection to whatever dodgy website they like and mail should be screened for questionable content. If you think that this sort of thing wouldn't be happening on Linux (or anything else) if it had so many clueless users in business settings using the product - you're deluded.
I run: Windows, OS X, Linux, FreeBSD. Just because you have a hammer, doesn't mean everything is a nail.
Setup a non-transparent proxy, push out proxy settings to all your users (with GP or whatever, or do it manually), drop egress Web/IRC traffic. Now sit back and watch your firewall logs for alerts (or better yet setup syslog-ng or Kiwi Syslog Server to send you alerts) -- anything banging against the firewall is something you need to look at. Why? Because malware is rarely proxy-aware -- it assumes (rightfully so) that people either use transparent proxies or have no outbound filtering setup so when it tries to phone home, it'll make a lot of noise.
body massage!
...is that the rootkit's version went from 3.25 (unpatched) to 3.26 (patched). That's a lot of versions we didn't know about.
Or maybe your issues have nothing to do with this update or the rootkit.
Some ISPs notify their customers if they're participating in a botnet, and cut their service is nothing is done about it. They're only doing it out of their own interest, but I wouldn't mind federal governments making this mandatory.
This isn't the first time that an update from Microsoft breaks an infected PC. It's not something they plan or test for, nor should they.
The same week they put out a miserable Zune update that caused my Zune to find its way to the trash can.
The last update to the Zune HD firmware was in November. The most recent update to non-HD Zunes was in September. The problem they're talking about happened in February. We're probably not talking about the same issue.
But you repeat yourself. Windows machine. 'nuff said.
Linux is so easy now, just dual boot and do banking from Linux. Then your worries would be much reduced.
Well, one possible explanation would be that this rootkit snuck into one or more of Microsofts update servers. Wouldnt surprise me at all actually. Microsoft would never ever acknowledge something like that or tell the outside world.

Thank Christ the bank in question doesn't allow you to do anything without the use of a separate security device they ship you.
Or, just use a Linux Live CD for all your banking needs. Maybe the banks should require all users to use at least a Linux Live CD to access any of the bank's websites.
They could hand over VirtualBox with an installed and configured Linux distribution on a CD/Usb stick to it's customers (CD would be better, it's write protected).

The rootkit in question was Zeus, which is known to evade many AV scanners. It probably wouldn't have made much difference what I was running - and more than one rootkit in the wild today is designed to account for the fact that a user may not have admin privs.
Mail is screened, but I can't easily control their internet connection when the computer in question is a laptop. Otherwise there would be little point in issuing laptops.
I fully accept that Linux would be just as big a target if everyone had root privs and it was anywhere near as popular. I also accept that you can't protect against user stupidity.
But right now, today, there are very few Linux trojans and rootkits in the wild compared with Windows. I don't believe a 100% malware proof computer is even physically possible, but making it 98% malware proof would be a hell of an improvement on the current situation.
That's an interesting idea.
The problem is, this is something that affects my work - I'm the sysadmin - and I guarantee you that as soon as you start putting roadblocks like that in people's way, they start to look for ways around them.
I'd also have to screw around with the laptop to prevent Windows accessing the bank's website (easiest answer would be a few strategic entries in the hosts file) - but the inevitable upshot is that I guarantee the enduser would wind up doing something like using their own PC for banking rather than rebooting the laptop. At least I have a chance (however slim) of being able to manage the risk on the laptop I give them.
We have recently ditched Symantec anyway - not for this reason, I hasten to add, because I was unaware of this when we ditched it - and the new AV product is a suite complete with managed firewall, browser protection and every conceivable bell and whistle.
(Yes I know Symantec also produce such a product. But it requires a Windows server which would have been quite a bit more licensing expense considering all my backend infrastructure is Linux).
which affect everybody that make me consider more and more everyday to do egressive filtering on my external firewall. Granted, I'm usually the only one using my machine and I typically am careful with my browsing habits on any platform (linux, freebsd, solaris or windows; javascript can be nasty). Stuff like this makes me feel really vulnerable on my windows based machines, though.
Oh for the love of Pete! Microsoft is MOST DEFINITELY RESPONSIBLE for rootkits! Sure, their patch is not the direct cause of the BSOD but letting the damn malware into the OS certainly is the real problem. Stop dancing around the spin and address the real problem for once!
It is possible for malware running on a limited user account to execute on Windows and bootstrap itself into place via the HKLM registry where is should not be allowed to write. In addition, it can place executables into C:\Windows\System32 where it should also not be allowed to write or replace files. Next, malware can actually inject code into WINLOGON.EXE while it's running in RAM. Now you must ask yourself, WHAT THE FRAK?!?!
The Zeus bot tool can be downloaded by any luser without a clue to build a custom rootkit via a Win32 Wizard for crying out loud! The bots produced with such a tool incorporate encryption both for the malware files as well as phoning home to the botnet itself. AV software cannot stop it! Once you are rooted, you machine is now owned by the botnet. Even Symantec, McAfee and Kaspersky have had their own computers infected by bots produced by Zeus!
Running around the security perimeter trying to fight off the hoard after the fact, is futile.
Repeat After Me:
- Windows Cannot Be Secured!
- Windows is Insecure!
- Windows is a Security Hazard!
- TIME TO GET OFF WINDOWS!
Yeah it's going to cost you big time, but it's going to cost a whole lot more if corporations don't start acting soon! Many companies have been hacked and the hackers are going after the financial staff, gaining access to online bank accounts and stealing tens of thousands of dollars! Most business banks provide no recourse nor protection if someone else logs in with your account and wires money to a third world country.
