Hi guys,

 

 

on Monday I've noticed that all my folders were messed up. After inspection, I saw that they were modified one after another through a peroid of roughly 4 hours.

After opening one of the folders, I see a readme.html file and that all the files are missing. After right clicking I could see they were there and could be unhidden.

After googling about ransomware, and finding this forum, I've followed this site and found this link:

https://id-ransomware.malwarehunterteam.com/

 

 

 

Uploading the ransom note told me that the ransomware in question was unfortunately CryptXXX 3.0.

 

 

 

From what I get it, there isn't yet a decryptor for the 3.0 version. Unfortunately, i don't have a back up. Fortunately, not all files were lost. Now I'd like to back up the important files to DVDs (would an external hard be a bad idea?). I'm a bit afraid to burn the files to a DVD only to later infect my computer if I manage to get rid of the ransomware.

 

 

I've scanned the computer with Avast and AVG and there were no threats found. I've also scanned with SpyHunther- which found a trojan and 485 other threats but I could not delete it as this was a free version (reading this forum, I've also read that the trojan could be a false alarm by Spyhunter?).

 

 

 

My plan now is to install Malwarebytes and EMISOFT antimalware and do a deep scan. I hope they find something.  I'll also post a FRST log.

Could the ransomware have deleted itself if it can't be found by several programs?

Which antimalware (free one) would you reccomend if the ones I mentioned don't work:( ?

Any files that are encrypted with CryptXXX 3.x will have the .cryp1 (UltraDecryptor), .crypz (UltraDecryptor) or a random 5 hexadecimal character (UltraDecryptor) extension (i.e. ..AC0D4, .DA3D1, .73E61, .EF538) appended to the end of the encrypted data filename as explained here. The newest CryptXXX (Microsoft Decryptor) does not change file extensions and uses a generic file (ransom note) named "README.HTML".

A repository of all current knowledge regarding CryptXXX is provided by Grinler (aka Lawrence Abrams), in this topic: CryptXXX Ransomware Help, Information Guide and FAQ.

There is an ongoing discussion in this topic where you can ask questions and seek further assistance. Other victims have been directed there to share information, experiences and suggestions.Rather than have everyone with individual topics, it would be best (and more manageable for staff) if you posted any more questions, comments or requests for assistance in the above support topic discussion...it includes experiences by experts, a variety of IT consultants, end users and company reps who have been affected by ransomware infections. Doing that will also ensure you receive proper assistance from our crypto malware experts since they may not see this thread. To avoid unnecessary confusion, this topic is closed.

Thanks
