Hi! 
My mother's desktop pc just got infected. 
I'm sorry I'm not in the mood to introduce myself, just because I'm panicking for the reason above.
 
trying to be "zen wise" I can just tell that we live in such a cruel world where a small distraction can lead you to panic, but where panic can lead you to awareness.
 
I just mean I got into this forum that looks like a great community and despite what happened I'm very happy.

(still wondering why this sh*t is happening mainly in Italy..)
 
Ciao

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. TeslaCrypt 3.0 .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, Howto_Restore_FILES.TXT and help_recover_instructions+[random].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 in this BC News article: TeslaCrypt Decrypted: Flaw in TeslaCrypt allows recovery of encrypted files. Instructions on how to recover the key for decryption are also included in TeslaDecoder.zip.

Currently, there 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 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.

Thanks
