Hi i hope you can be of some help. I am working on a server in which some of the data files hve been converted to .vvv .  I have scanned with the id tool and sophos and there is nothing found. Do you think that it is possible that the infection is on one of the clients and that it may have infected a mapped drive or am I dealing with a newly emerged variant

Hi, I have a problem with .vvv files in my father's workstation, and he's lost all his work documents. Maybe they can be recovered?

I have found a file named recover_file_xlgfkxxqg.txt.vvv, but I can't inspect it on MS Office or notepad.

@ jackslater74, pjromero

You both are dealing with a newer variant of TeslaCrypt/Alpha Crypt.. TeslaCrypt includes several known versions and extension variants to include: .ecc, .ezz, .exx, .zzz, .xyz, .aaa, .abc, .ccc., .vvv...as described here. More information in this BC news article:Any files that are encrypted with the newer variant of TeslaCrypt will have the .exx, .xyz, .zzz, .aaa, .abc, .ccc or .vvv extension appended to the end of the filename. The .aaa/.abc/.ccc/.vvv variants leave .html, .txt, files (ransom notes) with names like Recovery_File_*****.txt, restore_files_*****.txt, recover_file_*****.txt, HOWTO_RESTORE_FILES_*****.txt, howto_recover_file_*****.txt, _how_recover_*****.txt (where * are random characters). Some of the new variants are disguised as CryptoWall.

A repository of all current knowledge regarding TeslaCrypt, Alpha Crypt and newer variants is provided by Grinler (aka Lawrence Abrams), in this topic: TeslaCrypt and Alpha Crypt Ransomware Information Guide and FAQ

Information about and support for decrypting files affected by Alpha Crypt & TeslaCrypt ransomware can be found in this topic:
TeslaDecoder released to decrypt .EXX, .EZZ, .ECC files encrypted by TeslaCrypt

There is an ongoing discussion in this topic where you can ask questions and seek assistance.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. 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.

Thanks

Hello,

I believe I am dealing with the same type of ransomware, all documents and archives were renamed to <filename>.<extension>.vvv and encrypted.
It seems to me like the latest version 8 of TeslaCrypt, judging by the information from this webpage, but none of the tools or methods listed is helpful.
I submitted an example xls file as requested.

Thank you for your time and efforts!

Yes the .vvv extension is the latest variant of TeslaCrypt...see my reply in Post #3. Use the links I provided there for any support questions.

I spit all the above postings from another member's topic since they are all related to the new TeslaCrypt variant.

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. 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
