Need help in identifying malware and decrypt files

Hello

Recently i was infected with some ransomware and i was unable to open any files on my system.

.

Files in following format were created in every folder,

+REcovER+(some random 5 characters)+.html

+REcovER+(some random 5 characters)+.png

+REcovER+(some random 5 characters)+.txt

and it contained notes like below,

........

Also files names extension hasn't been changed at all.

I am not able to confirm which malware it is and if its possible to decrypt back the files.

So please help to provide any info related to this.

TeslaCrypt 4.0 no longer uses an obvious extension for encrypted filenames...although when first released it used the .mp3 extension. TeslaCrypt 4.0 will leave files (ransom notes) with names like RECOVER+[random].TXT, RECOVER[5-random].TXT, recover_file.txt, _rEcOvEr_[5-random].txt, +-HELP-RECOVER-+[5-random]-+.txt and +REcovER+[5-random]+.txt. More information in this BC News article: TeslaCrypt 4.0 Released with Bug Fixes and Stops Adding Extensions.

You can submit samples of encrypted files and ransom notes to ID Ransomware for confirmation.

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

Currently, there is no way of decrypting TeslaCrypt 4.0 or TeslaCrypt 3.0 .xxx, .ttt, .micro, .mp3 variants unless you pay the ransom since they use a different protection/key exchange algorithm, a different method of key storage and the key for them cannot be recovered. The .xxx, .ttt, micro and .mp3 variants do not have a SharedSecret*PrivateKey so they are not supported by the current version of TeslaViewer. The tool can decrypt TeslaCrypt 3.0 files only if you have the private key acquired from the malware developer after paying the ransom. If infected with any of these extensions, backup all your encrypted files and wait for a possible solution.

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.

• TeslaCrypt 3.0/4.0 .XXX, .TTT, .MICRO, .MP3 Support & Discussion

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 the support 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
