TeslaCrypt includes several known versions with various extensions for encrypted files such as .ecc, .ezz, .exx, .xyz, .zzz, .aaa, .abc, .ccc, .vvv as described here. The .xxx, .ttt, .micro variants are described in this news article.

Any files that are encrypted with TeslaCrypt 3.0 will have the .xxx, .ttt or .micro extension appended to the end of the filename. Any files that are encrypted with TeslaCrypt 2.0 (AlphaCrypt) will have the .ezz, .exx, .xyz, .zzz, .aaa, .abc, .ccc or .vvv extension appended to the end of the filename. Any files that are encrypted with the original TeslaCrypt will have the .ecc extension appended to the end of the filename.

The .xxx/.ttt/.micro variants leave .html, .txt files (ransom notes) with names like recovery_file_[random].txt, recover_file_[random].txt, and Howto_Restore_FILES.TXT. The .aaa/.abc/.ccc/.vvv variants leave ransom notes with names like Howto_Restore_FILES.txt, RECOVERY_FILE_[random].txt, restore_files_[random].txt, recover_file_[random].txt, Howto_RESTORE_FILES_[random].txt, howto_recover_file_[random].txt, _how_recover_[random].txt, how_recover+[random].txt. The .ezz/.exx variants leave ransom notes with names like HELP_TO_SAVE_FILES.txt and RECOVERY_FILES.txt. The .ecc variant leaves ransom notes with names like HELP_RESTORE_FILES.txt and HELP_RECOVER_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

Information for decrypting files with .ecc, .ezz, .exx, .xyz, .zzz, .aaa, .abc, .ccc, or .vvv extensions can be found here and in this support topic. Instructions how to recover the key for decryption are included in TeslaDecoder.zip.

There currently is no way of decrypting TeslaCrypt 3.0 .xxx, .ttt, or .micro variants since they use a different protection/key exchange algorithm and the key for them cannot be recovered. The .xxx, .ttt and .micro variants are not supported by the current released version of TeslaViewer. If infected with any of these, 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.Support for decryption requests can be posted in this topic: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.
