I had someone bring a PC to me today that is infected with some variant of Cryptolocker. The expiry period has passed already. I've attached a picture of it. I had the good sense not to plug it into our network (I never do with any untrusted systems). The picture looks like normal Cryptolocker and there's an icon on the desktop that says Cryptolocker, but I was under the impression that the original Cryptolocker network was shut down and that the keys were publically available to combat the problem.
 
The person who brought it to me claimed they had a friend who was using their computer yesterday, but I suspect the infection was probably on their system for awhile (most of the screenshots of Cryptolocker I've seen have been at least 50+ hours). I noticed there's a VV72 number in the top left, is this a variation #.
 
Where to start next?
 
Since the system (Windows XP) is a Dell Inspiron 2400 that probably only has a 40GB HDD inside I was thinking I would just replace his hard drive, reinstall using his license on the new drive and we'd ditch his old drive. The person was okay with this idea since much of their work is attachments in their Hotmail/Outlook email. (thinking some of them might be infected). But I'm posting here for interest sake and willing to do some troubleshooting for the sake of giving back and furthering research.

Hi chaslinux :)

This system is infected with TeslaCrypt. There's currently a support thread on-going for TeslaCrypt where you can ask for assistance and seek answers to your question. I'll ask you to go post there since it's better to have all the information centralized instead of having hundreds of threads about the same issue. The thread can be found at the link below.

New TeslaCrypt Ransomware sets its scope on video gamers

For now, Lawrence Abrams (aka Grinler, the Founder and Owner of BleepingComputer) recommends to not pay the ransom and that "something" might be on it's way. So I would follow the thread and pay attention to it. See his post below:

Good luck :)

Any files that are encrypted with TeslaCrypt will have the .ecc extension added to the end of the filename. At this time there is no fix tool and no way to decrypt the files.

There is an ongoing discussion in this topic: New TeslaCrypt Ransomware sets its scope on video gamers

Rather than have everyone start individual topics, it would be best (and more manageable for staff) if you posted any questions, comments or requests for assistance in that topic discussion. To avoid unnecessary confusion...this topic is closed.

Thanks
