Trojan Using Sony DRM Rootkit Spotted
Analise writes "The Register reports on the first trojan using Sony's DRM rootkit. A newly discovered variant of the Breplibot trojan makes use of the way Sony's rootkit masks files whose filenames begin with '$sys$'. This means that any files renamed this way by the trojan are effectively invisible to the average user. The malware is distributed via an email supposedly from a reputable business magazing requesting that the businessperson verify his/her attached 'picture' to be used for an upcoming issue. Once the payload is executed, the trojan then installs an IRC backdoor on affected Windows systems."
I reccomend voting with our wallets, and not purchasing Sony/BMG products. Also see here
Also here is the company that created the DRM technology.
Since there was some confusion about how you can tell if this rootkit is installed, remember that it hides files beginning with '$sys$' -
1) If you're not using windows, you're fine.
2) Create a file on your desktop ('test.txt' should be fine). Rename the file to '$sys$test.txt'.
If the file is gone, you're vulnerable.

Can anyone explain if this rootkit prompts for a password when installing (during the autorun, I presume)
As an OS X user, I'd find it slightly odd that my music CD is prompting me for an administrative password.
But to stay on topic, I'm sure this is but one of the many exploits that will be based on this rootkit.
Does anyone have a comprehensive list of CDs that install it, and is it true that Sony has been using it since April?
If you don't know what AltaVista is (was), get off my lawn.
Here's the Slashdot crowd's chance to get the phrase invented by a Slashdotter out in the public eye. It's important that the public learn that DRM is a bad thing, and this is simply one way to tell them plainly how it is bad. DRM breaks their computer, or makes their life more difficult.

"Infected with DRM"
Sony's rootkit has also been linked to Windows crashes, which isn't surprising to me. Most spyware causes instability in Windows because it is poorly written and designed to break parts of Windows to protect itself from removal. Sony writes, "This component is not malicious and does not compromise security. However to alleviate any concerns that users may have about the program posing potential security vulnerabilities, this update has been released to enable users to remove this component from their computers."
The incongruence of their words, is not startling to me, as they are playing a PR game to hide the fact that they messed up people's computers, and made them vulnerable to an attack that hasn't gained popularity yet, but now surely will. Virus writers will be able to easily hide their virus files using programs like Sony's cloaking DRM. Sony is lying that their cloaking DRM does not compromise security of an infected computer.

Saskboy's blog is good. 9 out of 10 dentists agree.
Eh, that's a little "I was only following orders" for my blood.
If I'm working for a homicidal maniac and I build a gun for him, I'm not innocent when he goes on a rampage.
Werner Heisenberg claims that he sabotaged the Nazi atomic bomb effort. If that's true, this would have been a very different world if he had just decided to be a "good engineer." (Yes, Godwin, blah blah. I don't think it applies.)
The sales manager at the company I work for recently received a variant of this worm, and after finding that the attachment "didn't do anything" forwarded it on to me to find out why. I extracted the attachment and analysed it in IDA and discovered that it connected to one of two IRC servers and joined a specific channel.
.. suddenly they all quit and the room was empty except for me and the op.
.. I felt quite akin to him in many ways.
So posing as the trojan I logged onto the IRC channel. I idled there for a while watching the channel op send commands to the connected bots, and decided to have a go myself. The channel was +m but I could PRIVMSG the bots, and a bit more work in IDA revealed the command set - which contained an unload command. So I scripted my irc client to send a msg to every non-op in the channel with the command
"OH SHIT" he typed. He was more shocked than anything, and then more curious than angry. We ended up having a rather long and interesting conversation about our respective jobs. He told about his bot network, what he uses them for (in the UK it's for harvesting email addresses, apparently), the ££ he gets for it - it's a full time job for him - and who writes most of the bot software (his partner.) He was no stereotypical teenage script kiddie either, more a computer professional turned to the 'dark side' of IT
All in all, it was fascinating. (Btw, our firewall blocked the trojan from connecting to IRC and it was fairly easily to remove from the sales manager's laptop)
IF antivirus vendors do start removing the sony rootkit, won't that qualify as circumvention of a copyright device and put them in clear violation of the DMCA? This just keeps getting better and better.
There is not nearly enough love in the world, but there is far too much trust.
The following year, all traces of this were removed in the next version and, afaik, it has never returned. I, for one, however, haven't bought their product since and don't plan to ever buy from them again.
I guess Sony just wasn't paying attention.
