You are dealing with the newest variant of TeslaCrypt ransomware...TeslaCrypt 3.0 will have the .xxx, .ttt or .micro extension appended to the end of the filename as described in this news article and leave .html, .txt files (ransom notes) with names like recovery_file_[random].txt, recover_file_[random].txt, and Howto_Restore_FILES.TXT.

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 currently is no way of decrypting TeslaCrypt 3.0 .xxx, .ttt, or .micro variants 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 and .micro variants do not have a SharedSecret*PrivateKey so they are not supported by the current version of TeslaViewer. If infected with any of these extensions, backup all your encrypted files, send BloodDolly a private message with a link to few encrypted files after uploading them to SendSpace (see instructions in Post #1) and wait for solution.

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

• TeslaDecoder released to decrypt .EXX, .EZZ, .ECC files encrypted by TeslaCrypt Support & Discussion

You can also post comments in the related BC News article:

• TeslaCrypt 3.0 Released with Modified Algorithm and .XXX, .TTT, and .MICRO File Extensions

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 one of those topic discussions, particularly the last if dealing with one of the newer variants. 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
