Welcome to BC and sorry to hear about your infection.
You are dealing with a newer variant of
TeslaCrypt 3.0 ransomware which will have the
.xxx,
.ttt,
.micro or
.mp3 extension appended to the end of the filename as described in this
news article. More information about the
.mp3 variant is described
here.
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.
Currently, there is
no way of decrypting TeslaCrypt 3.0
.xxx, .ttt, .micro, or
.mp3 variants unless you pay the ransom 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, micro and .mp3 variants do not have a SharedSecret*PrivateKey so they are not supported by the current version of TeslaViewer. The tool can decrypt TeslaCrypt 3.0 files
only if you have the private key acquired from the malware developer after paying the ransom.
If infected with any of these extensions, backup all your encrypted files and wait for a possible solution.
There is an ongoing discussion in this topic where you can ask questions and seek further assistance but as noted above there is no solution to fix your encrypted files yet.
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.
Thanks
The BC Staff
