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."

  4. A Natural Rights perspective by dada21 · · Score: 5, Insightful

    Irregardless of the existence of government, the natural rights of an individual cannot be given away (you can't sell yourself into slavery, you can't tell a higher power that it's ok to kill you). One such right is the right to private property, closed to others' prying eyes or presence.

    One great force behind this right is that past acts bear no allowances for future acts. If I let you into my house yesterday, you have no right to be here today. I may contractually allow you to come and go as you please, but I have to willfully sign the contract with witnesses noting the act.

    Sony's DRM uses government force (through copyright provisions) to settle its legality. They say that by using their property, you have to permanently give up your natural right to private property (free speech Statists wrongfully call it Right to Privacy). Sony is wrong.

    By violating numerous natural rights, Sony has opened itself to a demand for restitution. I wholeheartedly believe that corporate protections are wrong, as is copyright. My solution? Go after Sony through the shareholders directly (they own the business and allowed the breach of a basic human right). Demand restitution for the trojan if you receive it.

    Imagine if you buy a Saab and Saab has an agreement stating "If you turn the car on, you allow two Saab employees to ride in your trunk and search your house for proof you might install a non-Saab oil filter." You've signed nothing. The two Saab employees open your house door, take up residence and leave the door wide open. Two typical pro-copyright arguments: You're not allowed to install non-Saab oil filters or how else would Saab make money? Why would they design cars?

    This is the problem with copyright. Instead of individuals protecting proprietary information of value (books, music, etc) and producing it in the best way over anyone else (live shows, subscriptions to new music, etc), they say "copy us and government will use force against you."

    It's all wrong. Don't publicly say anything valuable to you. Don't think you can come in my home because you did once before. Don't think you can rape me because a note in your pocket says you're allowed to, and I let you in without checking your pockets.

      Darren Dittrich followed up on the discovery that Sony was playing a dirty trick on its customers, secretly installing a malware-style "root kit" on their computers via audio CDs:

      I recently purchased Imogen Heap's new CD (Speak for Yourself), an RCA Victor release, but with distribution credited to Sony/BMG. Reading recent reports of a Sony rootkit, I decided to poke around. In addition to the standard volume for AIFF files, there's a smaller extra partition for "enhanced" content. I was surprised to find a "Start.app" Mac application in addition to the expected Windows-related files. Running this app brings up a long legal agreement, clicking Continue prompts you for your username/password (uh-oh!), and then promptly exits. Digging around a bit, I find that Start.app actually installs 2 files: PhoenixNub1.kext and PhoenixNub12.kext.

      Personally, I'm not a big fan of anyone installing kernel extensions on my Mac. In Sony's defense, upon closer reading of the EULA, they essentially tell you that they will be installing software. Also, this is apparently not the same technology used in the recent Windows rootkits (made by XCP), but rather a DRM codebase developed by SunnComm, who promotes their Mac-aware DRM technology on their site.
    3. Re:Back again to Windows Security by _xeno_ · · Score: 4, Informative

      Short answer: No, it just assumes you're running as an administrator, which is generally true.

      Much longer answer:

      Windows XP comes from two roots: Windows as a DOS shell, and Windows NT. Both of these operating systems encouraged running as Administrator, for a variety of reasons.

      Windows as a DOS shell is easy to explain, it was a single-user system, and therefore really had no security system in place at all. This single-user style persisted through to Windows ME, and is essentially "emulated" in Windows XP Home by having the users, by default, run as Administrators. (You can change them to regular users after creating new accounts, though.) By default, Windows XP Home doesn't require passwords on accounts - you just click on the user account you want to use, and you're logged in. So even making "less privileged" users isn't all that helpful. (I believe, by default, Windows XP Home DOES disable the built-in Administrator account, though.)

      Anyway, Windows NT is another story. Technically, an "Administrator" account is just a normal user account that just happens to belong to the Administrators group. Because Windows NT's security model is much more complicated than the Unix security model (and I'd argue much more robust), essentially the Administrators group is a group with all permissions set to "allow." (There is a super-user under Windows NT. It's called "SYSTEM" and it's essentially identical to root under Unix.)

      But anyway, Windows NT's security model is very complicated. Combined with no ability to "sudo" in Windows NT 4, most people who used NT just made themselves Administrators so that they didn't have to poke around the miriade of settings and ACLs to give them permissions to do whatever they needed to do.

      Windows 2000 added "Run As" which allows you to essentially "su" and switch to another account when starting a program. This meant that it would in theory be possible to administer a system from a non-privileged account, much like Mac OS X does.

      But the damage was already done. Most of the Windows software had been written for Windows 9x or assumed that you'd be an administrator under Windows NT. So attempting to run as a non-privileged account required constantly using the Run As feature to run the programs you needed to use as an administrator. (For a while, Winamp wouldn't run under a non-privileged account.) Of course, this meant that since most programs were running as administrator ANYWAY, you really weren't gaining much security.

      Now, with Windows XP Pro, this is starting to change. Microsoft now requires user programs to run on non-privileged accounts. It's much clearer where user-specific information goes. But the damage has been done. Windows XP Home defaults to an administrator account for all new accounts. Most people are used to not having to enter a password to change their system settings and don't understand the concept of a non-privileged account.

      So almost everyone using Windows is running as an administrator, and therefore there's no need to require a password to install a rootkit. They already have the permissions they require.

    "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.

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.

    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 .. suddenly they all quit and the room was empty except for me and the op.

    "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 .. I felt quite akin to him in many ways.

    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)
