You are most likely dealing with a newer variant of TeslaCrypt which is for the most part the same as Alpha Crypt.

Any files that are encrypted with TeslaCrypt will have the .ecc extension appended to the end of the filename.
Any files that are encrypted with Alpha Crypt (TeslaCrypt renamed) will have the .ezz extension appended to the end of the filename.
Any files that are encrypted with the newer unnamed variant will have the .exx, .xyz, .zzz or .aaa extension appended to the end of the filename.

A repository of all current knowledge regarding TeslaCrypt and Alpha Crypt 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 Alpha Crypt & TeslaCrypt ransomware can be found in this topic:
TeslaDecoder released to decrypt .EXX, .EZZ, .ECC files encrypted by TeslaCrypt

There are ongoing discussions in these topic:

• Alpha Crypt (TeslaCrypt renamed) Ransomware Support & Discussion
• TeslaCrypt Ransomware Support & Discussion
• New TeslaCrypt version that uses the .EXX extension

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. 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
