Windows Users Fear Korgo Virus
An anonymous reader writes "A new virus is on the prowl that can infect your Windows XP/2K system and record every key you hit on your keyboard. The keys are then sent back to the virus creator where he/she can steal your passwords and credit card information. The virus named, Korgo, started showing up in the last week of May but it now has at least six different variants. To protect yourself from this nasty virus, Microsoft is urging all users to download the KB835732 Security Update. As with the Sasser worm, you'll get the Korgo virus without even knowing it. It does not arrive by email, but simply by being connected to a network or to the Internet without having a patched machine or a properly configured firewall."
Main details from top of SARC page: Happy cleaning.
The company that I work at pushed the KB835732 patch out to a few thousand machines. It caused some incompatability issue that cause Windows to blue screen with the error "Winsrv.dll missing or corrupt", its been a blast removing the patch through recovery console, especially walking remote users through it.
For those that have just come out from their rock, here is a removal tool for this latest worm
And IIRC, shouldn't any good (read: non-XP) firewall automatically be blocking these ports (or atleast 445) right out-of-the-box?
Hmmm.
Symantec's Advisory. Listens on TCP ports 113, 2041, and 3067. 113 is identd, 2041 is interbase, 3067 seems invented. Firewall as appropriate.
I wish that, just once, a lot of people will get ripped off. The credit card companies will cover any losses (they have to by law), and people will actually realise that yes, keeping up to date with patches is a good idea.
Puny humans fear Korgo...
Microsoft Security Bulletin MS04-011
Security Update for Microsoft Windows (835732)
Issued: April 13, 2004
Updated: May 4, 2004
Version: 1.3
If you "just get it" without having to run anything, it's a worm, not a virus. It's not complicated.
...you're new here, aren't you?
"Sent back to the creator" means data is dumped into an IRC channel, newsgroup, or possibly some zombied machine. There's little way to track the person behind the bot, so to speak.
Of course, a little way is all it takes to pinch some angsty German teenager...

I for one salute our new script kiddie overlords.
Let's not forget that most users (which wouldn't be reading /.) don't have any idea about this stuff. This confuse virus scanners with firewall, and think patching is something you do with clothes. So no, they don't really deserve it.
Like it or not, they want their PC to work like their television. As much as you or I don't like it, they are the people that are keeping Windows suppport folks employed.
I can't say how many times I've helped with someone's machine, and they've had multiple virus infections, spyware and general crap on their machine because they don't know any better. It's a fact of life that Microsoft is going to have to own up to if they want to stay on top. They raised the beast, now they need to teach it the rules.
It's 11PM, do you know where your pants are?
>Are people really this daft?
Yes. Welcome to reality, enjoy your stay.
The surprise isn't how often we make bad choices; the surprise is how seldom they defeat us.
Sadly, that's not the bottom 5% of the userbase. In the last three months, I've had to fix six home user computers and one that was used to track the finances of a church. Four of the home computers had never had Windows Update run (and both of the other two had only been force-fed updates through manufacturer-installed support software), and the Church computer was still vulnerable to the Blaster worm (Thankfully the thing wasn't connected to the Internet)
is not slashdotted? They are running Windows Server 2003 with IIS and everyone here knows that is bad...
F-Secure Weblog says Korgo doesn'ts install a key logger by default, but that the "cracker team" uses Korgo's backdoor to do so. So, you wont necessarily have the key logger installed if you have any of the Korgo variants. At least, none up to this point...
When I first saw this I thought I read a virus named Torgo! It wobbles around, moves slowly, and takes care of your computer while you're away.

Just cache all your passwords and credit card info in your browser's form remembering thing.
Thank God I trust Internet Explorer enough to remember my bank password for me... now I don't have to worry about viruses that log my keystrokes!
It's easy for us to say that, we're computer users who (presumably) know what we're doing. But if one is to condemn non-patchers in that way - I assume you also change your oil every 3000 miles, go to the dentist every 6 months, floss daily, get an annual physical, clean the lint filter in your dryer after every load, eat 6 daily servings of vegetables, rotate your tires every 20,000 miles, have all your car's factory recalls done, change the air filters in your heater monthly, and perform all the other mindless routine maintenance you're supposed to do.
The bottom line is, no one on earth outside the most anal retentive person alive does all that stuff. Not doing any of them could have consequences, but people simply don't have time to do all this shit.
So yes, I do blame microsoft. One shouldn't have to constantly check symantec's web page just to keep your computer usable. Computers are appliances now. They should just work, dammit.

What a surprise it wasn't mentioned that this was patched months ago, right?
This vulnerability is the LSASS Buffer Overrun Vulnerability, already patched way back on April 13. Slashdot probably had at least two or three articles on it back then as well if you wanna do a search for "sasser."
If you haven't patched after two months, you're just the same as all those people who got hit with Blaster, which was also already patched beforehand. Linux distros issue security patches for their vulnerabilities weekly and nobody complains, but when Microsoft releases a patch, suddenly it's this huge issue to run a tiny executable that plugs security flaws, and then people bitch at Windows two months later when a virus comes out to exploit it...
Just saying. How can one criticize their security if they won't apply their security patches? Almost all major software is gonna require a patch eventually. I don't get this steadfast need to avoid patching Windows boxes while freely recompiling Linux kernels on a whim for production servers when a minor point release comes out.
"Sufferin' succotash."
The virus named, Korgo, started showing up . . .
I highly recommend that the submitter (Anonymous User) immediately head over to his/her favorite online book retailer and purchase Eats, Shoots and Leaves.

SERENITY NOW!!!!!!!!!!!!!!!!
Yes, and the 011 patch also killed about 5% of the machines it was installed on before the May 4 update. Now it only kills about 1%, or about 100 machines in our case. Not to mention the several apps it killed.
This sig is the express property of someone.
yes, it's a shame, very few virus writers are supporting win98. please upgrade to win xp for the latest viruses. ;-D
Good of you to propagate this idea, except it doesn't hold water. May I draw your attention to the Apache web server vs. IIS.
Windows is indeed a larger target, but the fact that Windows gets hit more often is its the easier of the two, virus writers are just like the rest of us, lazy. These flaws in Linux differ from those in Windows in that its so much easer to exploit the Windows ones.
Windows has a larger attack area, but whomever is the first to successfully attack and damage Linux in the same way is going to go down in history, whereas who cares about who writes these, there's no skill involved.
"I use a Mac because I'm just better than you are."
"Windows Users Fear Korgo Virus" screams the headline, reading not so much like news as just another WindowsXP sales pitch. Yes, it's true -- Windows users DO fear the Korgo virus, while the insignificant and ostracized Mac and Linux users of the world are left, yet again, fearing only the sheer and utter BOREDOM of not having any viruses or trojans to fix due to their curious choice of OS. In the area of viruses, trojans, and worms, Linux and the Mac really do stand out as being "second class citizens", trapped in a virus-free ghetto with no salvation in sight. The discrepancy is so obvious, the ultra-competitive Microsoft doesn't even feel the need to buy themselves an Official Gartner Group Research Study to prove that Windows is light-years ahead in this area. Even the most staunch Linux or Mac advocate is forced to admit it -- off the record, of course. Virus writers, known to be excellent coders who take pride in their tight, bugfree code, have overwhelmingly standardized on Microsoft Windows as their targeted system of choice in the deployment of their ongoing suite of virus applications.
And it doesn't look like the situation is going to get better any time soon.
One bearded Linux coder, who refused to be identified publicly, confessed "we just don't have the selection -- or quality -- of viruses on our platform that is available to Windows users free of charge. And it's tearing us up inside knowing that the battle is over, and Microsoft has clearly won." Similarly, a guy with an Apple logo shaved into the back of his head admitted the following once we turned off the cameras. "I don't mean to break ranks and insult our software selection," he whispered furtively, "but usually if we DO manage to get a virus that will even install on OS X, it's not that great, and we're left... disappointed, realizing that if we had simply stuck with the unwashed smelly masses, we too could be enjoying a daily barrage of free software delighting us by installing itself on our computers as a surprise gift. Instead, I'm stuck with the weak consolation prize of 40 Academy Awards for my work on Lord Of The Rings. But it's not the same. No amount of awards or million dollar paycheques can heal the feelings of neglect or massive abandonment issues this whole thing has given me."
"Is this the reason so many people choose Windows?", his innocent young son, Moof, asked me, looking like the kid off the Dave software box.
"What do you think, little one? Look at the Windows dominance in the virus field, then look at the marketshare of Windows. That ain't no coincidence, Moof. The other guys just can't keep up with the Microsoft Juggernaut. Microsoft is fighting hard to keep themselves Number One, just like the Titanic was the biggest and bestest ship, or the Hindenberg was the coolest and most flammable Zeppelin, or the dinosaurs were the toughest animals ever. How do you compete with that?"
=============
Yes, sitting here at my desk 16 hours later, WindowsXP Restore Disks in hand, I can't help but let a little smile shine across my face. Those poor fools, I think, using a non-Microsoft OS really does take away most of the joy of computing and replaces it with all that productivity and recreation crap. And where's the challenge in that?
Please insert Microsoft Windows XP Restore Disk 2
Ahhh, I sigh contentedly. It's gonna be a long night.
I'm not normally an irrational zealous dickhead, but I figure "When in Rome..."
I run RH 9 and FreeBSD 4.9. I looked at the list on the front page, and none of the issues put me at risk.
There are two reasons a person can be unaffected by the vulnerability if they don't patch. One is they don't have or run the affected software. Gnome users that never use KDE aren't impacted by KDE runtime vulnerabilities. The other is that their network is protected enough to render the vulnerability useless (firewall, local IP security, chroot, NAT, etc.)
The only vulnerability I've seen announced this year that I've had any concern about was the CVS one. Fortunately, though, I have yet to open up my firewall for outside access to CVS. When I do, I plan to use SSH, in which case the vulnerability wouldn't have impacted me. Thus, so far in 2004 between the two operating systems I have had no true vulnerabilities.
Sure, you could say the version of MySQL I'm running has the symlink vulnerability. But, if an attacker can't get local non-chroot'd shell access, then what relevance is a symlink vulnerability?
Contrast it to Korgo and Sasser, which hit Windows ports that are opened by default. I can't tell you how many times I see ports 135 and 445 in my daily logs of packet rejections. Plus, the infecting the processess using those ports gives the attack complete control of the sytem.
Windows is plauged by REMOTE vulnerabilities to MICROSOFT software. Linux distrubutions mostly have LOCAL vulnerabilities with the independent APPLICATIONS that are packaged with them, not the operating system itself. Most of these vulnerabilities require LOCAL access and most of this software runs on Windows as well (e.g., Apache), so the vulnerability usually applies to both operating systems, but appears on the linux security alerts simply because they are one of the thousands of optional programs being included on the FOSS CDs. You have to download Apache if you have Windows because Microsoft is not going to include it, and Microsoft isn't going to send you a patch for it, or even post an Errata, just because you are running it on Windows.
I've also administered Windows servers for many years, using Windows 3.1, Workgroups, NT 3.5/4.0, 2000 and XP, and used just about all their software, including Visual Studio, InterDev, IIS, and COM/DCOM. I still run 2000 and XP in addition to RH 9 and FreeBSD. I've developed my opinion from experience securing production servers in both Windows and Linux, as have other people posting on /.
