hi,
my parents contacted me since in the last days they have multiple windows open, each time they turn on the PC (windows 7 desktop).
 
I remote-connected to their PC, and what I saw was very disturbing:
dozens of open files, named like "Recovery+bcfnl", or "Recovery+xxxxx".. don't remember all the extensions..
 
also, by browsing the folders I found these files created in every folder in the PC. every single one contained hundreds of these files.
 
the files' types are html, txt, jpg, and all have the same text in them, asking to follow some flow to buy BITCOIN or something like that, giving a list of steps with links to follow etc.
 
first step, I installed AVG anti-virus, and ran a scan, which detected about 56 malware issues - and removed them.
I cleaned and deleted over 100,000 files from the PC, ran the scan again and rebooted the PC.
 
the next morning my mom says - it came back :(
again multiple windows open with these names..
 
did anyone hear about this kind of issue? any helpful tool that you know, which will help us to overcome this?
 
thank you,
Lina

TeslaCrypt 3.0 will leave .html, .txt files (ransom notes) with names like recovery_file_[random].txt, recover_file_[random].txt, Howto_Restore_FILES.TXT, help_recover_instructions+[3-random].txt, Recovery+[5-random].txt, _ReCoVeRy_+[5_random].txt, Recovery_[5_random].txt, _H_e_l_p_RECOVER_INSTRUCTIONS+[3-random].txt and RECOVERY.TXT.

 

TeslaCrypt 3.0 ransomware will have the .xxx, .ttt, .micro or .mp3 extension appended to the end of the filename as described in this news article. More information about the .mp3 variant is described here.

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.

There is an ongoing discussion in this topic where you can ask questions and seek further assistance but as noted above there is no solution to fix your encrypted files yet.

 

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
The BC Staff
