You are dealing with the newest variant of TeslaCrypt ransomware...TeslaCrypt 3.0 will have the
.xxx, .ttt, .micro or
.mp3 extension appended to the end of the filename as described in this news article. TeslaCrypt 3.0 will leave .html, .txt files (ransom notes) with names like recovery_file_[random].txt, recover_file_[random].txt, Howto_Restore_FILES.TXT, help_recover_instructions+[random].txt and _H_e_l_p_RECOVER_INSTRUCTIONS+[3-characters].txt.
Currently, there is no way of decrypting TeslaCrypt 3.0
.xxx, .ttt, .micro, or .mp3 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, micro and .mp3 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 but as noted above there is no solution to fix your 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.
... all the files on the laptop now converted to media files with .MP3 extensions.
No, your files are not converted to media files; they are just encrypted. Please do not try to remove/delete the appended .MP3 extension so as to avoid further corruption which might risk your recovery probabilities by any possible (actual or future) means.
- What's your Operating System (OS)/Windows version?
- What's your anti-virus (AV)/real-time protection (RTP) program installed?
- Any detection (name of detected malware) logged (most likely 'after-the-fact'
[data encryption], unfortunately) in History?
- Where (location) was this threat ('if' it was) detected? And what action was taken?
- Are there any 'ransom notes' files? => Search for files names like:
These ransom notes (.txt files) may be located in every folder where files have been encrypted, and they only contain the information for the
'ransom payment' - action which is, of course, NOT recommended! You should also see an
.html file with same or similar name and characteristics and containing same info.
Can you please post here a screenshot of your ransom note?
TeslaCrypt 3.0 was first released on January 12, 2016. Their newer and latest variant that was released by the crooks on or around February 11, 2016 is currently using this
.mp3 extension to add more confusion to victims.
Unlike data that was encrypted by prior versions (Tesla's V2.2 and below) which victims have been able to decrypt using
BloodDolly's TeslaDecoder, unfortunately - at this time - there is
no way of decryptingTeslaCrypt V3.0(.xxx, .ttt, .micro and/or
.mp3 extension-variants) since they use a different protection/key exchange algorithm, a different method of key storage, and the key for them cannot (yet) be recovered using the TeslaDecoder tool. These variants do not have a SharedSecret*PrivateKey
so they are not supported by the current version of TeslaViewer included with the TeslaDecoder tool.
BloodDolly, the author of the TeslaDecoder tool, and other experts and volunteers at bleepingcomputer.com, are certainly working on this already to find a solution.
If infected by the new TeslaCrypt v3.0, victims should backup all their encrypted files and wait for a future solution.
Restoring from backups is your only choice at this point, unless you get lucky with recovery software such as
PhotoRec - always at least worth a try. If these
methods fail, it is recommended to backup the encrypted files and save them on an external media in hopes of a solution in the future. Currently, there is no way of really marking how possible it is or how long it may take,
but the 'good guys at BC' are certainly trying hard.
Since all of the public keys and other encryption-related info are stored in the header of every encrypted file (Tesla leaves nothing else of use behind), once you have the encrypted files backed up by whatever means, you are free to reload the OS if you
wish. If there are any break-throughs, the backup of the encrypted files is all that is necessary for decryption when/if the expected free solution is released.
Please also note that, usually, main executables responsible for the encryption should have been deleted after the encryption completed. When TeslaCrypt is done encrypting files on a system, it deletes itself and leave only the ransom notes behind (and may
make them open on system startup). Any remnants 'should' have been cleaned off by your resident AV program or other removal tools of your preference.
Wish we had better news for you, but please keep us posted on any update to this thread. Your feedback is important to our Community.
-Tip: Please AVOID searching the Web for malware removal and decrypting tools for this (or any other) crypto-malware infection. You will only find 'scammers' and 'untrustworthy sites' offering 'fake
or dubious' tools that will only grant you an additional headache (or worse).
