Hi,

After I got infected with Teslacrypt, I rebooted my pc (it was much needed) and I put Linux (never got the time before infection-how I regret that).

 

I found several tutorials to decrypt my files (I saved them before reboot) but all are for windows (not a surprise there). The best one because I know very little and it is very extensive is https://up2sha.re/file?l=C5ag0MrQNqAb.pdf.

 

I used Blood Dolly's Tesla Decoder 1.0.1 (as suggested in the above tutorial) but when I got to the step I had to use Yafu I couldn't use it because I probably have the wrong commands.

 

Can anyone help?

I think (from what I can understand so far) that if I send (I will below) the keys I get from Tesla Viewer maybe someone (a much appreciated volunteer) can generate the key that I need, put it on Tesla Decoder and save me.

If that cannot be done please someone tell what commands I should use on Yafu (10-11p on tutorial) or suggest an equivalent program for Linux Mint 17.2 Cinnamon 32-bit (Cinnamon 2.6.13).

 

Thank you in advance.

 

 

What I get from Tesla Viewer:

Yafu works on Linux, I used to run it on there before setting it up on my i7. TeslaDecoder comes with specific instructions on how to run it already, the same directions apply to either OS since it is command-line.

 

Your PrivateKeyBC is a C138, will take awhile to factor if ECM doesn't uncover a factor. The PrivateKeyFile is a C96, NFS should uncover that in an hour on a decent system.

 

TeslaDecoder runs on Windows because, well, only Windows systems were affected, lol. TeslaCrack by Googulator is Python, so can run on Linux, but you need a different type of key (I think it ends up being the PrivateKeyFile, don't recall).

Support for TeslaCrypt 2.0 (and older versions) is provided in this topic where you can ask questions and seek further assistance..
Support for decryption requests is provided here:Decryption instructions for all victims of TeslaCrypt 3.0/4.x (.xxx, .ttt, .micro, .mp3) are provided by BloodDolly here.

Support for TeslaCrypt 3.0/4.0 is provided in this topic where you can ask questions and seek further assistance.Rather than have everyone with individual topics, it would be best (and more manageable for staff) if you posted any more questions, comments or requests for assistance in one of the above support topic discussions, particularly the last if dealing with one of the newer variants. To avoid unnecessary confusion, this topic is closed.

Thanks
