Welcome to Bleeping Computer.
TeslaCrypt (Alpha Crypt) includes several known versions with various extensions for encrypted files to include: .ecc, .ezz, .exx, .xyz, .zzz, .aaa, .abc, .ccc, .vvv, as described described here
Any files that are encrypted with the newer variant of TeslaCrypt
will have the .xyz
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, how_recover+****.txt (where * are random characters).
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 TeslaCrypt & Alpha Crypt ransomware can be found in this topic:
Since version 5 there is no way to decrypt the newer TeslaCrypt variants
(.xyz, .zzz, .aaa, .abc, .ccc, .vvv) without Tesla's private key or a purchased decryption key. It is no longer possible to get the encryption key from Tesla's request without Tesla's private key...since there is no private key anymore, it can't be used to decrypt files. See here
for possible decryption information with each version.
There is an ongoing discussion in this topic where you can ask questions and seek further 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...this topic is closed.
