ESET releases new decryptor for TeslaCrypt ransomware

Have you been infected by one of the new variants (v3 or v4) of the notorious ransomware TeslaCrypt? If your encrypted files had the extensions .xxx, .ttt, .micro, .mp3 or were left unchanged, then ESET has good news for you: we have a decryptor for TeslaCrypt.

We have been covering this malware for a few months now, sometimes along with Locky or being spread by Nemucod. Recently, TeslaCrypt’s operators announced that they are wrapping up their malevolent activities:


On this occasion, one of ESET’s analysts contacted the group anonymously, using the official support channel offered to the ransomware victims by the TeslaCrypt’s operators, and requested the universal master decryption key.

Surprisingly, they made it public.

This allowed ESET to create a free decrypting tool promptly, which is able to unlock files affected by all variants between 3.0.0 and 4.2 of this ransomware. For instructions on how to use the decryptor, please visit the ESET Knowledgebase website.


We must stress that ransomware remains one of the most dangerous computer threats at this moment, and prevention is essential to keep users safe. Therefore, they should keep operating systems and software updated, use reliable security solutions with multiple layers of protection, and regularly back up all important and valuable data at an offline location (such as external storage).

We also advise all users to be very careful when clicking on links or files in their email or browsers. This is particularly true when messages are received from unknown sources or otherwise look suspicious.

      I don’t think it handles .ECC Files. From the article: “If your encrypted files had the extensions .xxx, .ttt, .micro, .mp3 or were left unchanged, then ESET has good news for you: we have a decryptor for TeslaCrypt.”

      • Badtastic

        The link to the ESET KB site contains another link that identifies the infection. “Your ESET product detects the infection Win32/Filecoder.TeslaCrypt.” If you check out the details of that infection on their threat encycolpedia, ESET writes:
        “…An additional “.ecc” extension is appended.”
        I know it doesn’t say in the article, but it does seem to be geared toward .ECC files as well.

    is their any solution from .locky file all filename is change randomly and extension is .locky

    • Sorry. If this is really a Locky attack, I’m not aware of a viable decrypter. There’s a thing called AutoLocky that might be decryptable, but it doesn’t sound as if that’s what you have.

      • Rohit Patel

          How much are you willing to pay a programmer?
          Or did you think you were owed something?

        • Unfortunately, it simply isn’t possible to provide a decryptor for all ransomware, at any rate not within a reasonable timeframe. The universal decryptor is a Hollywood invention, I’m afraid, not a practical solution to ransomware. At any rate with our present technology. (Sorry I haven’t responded before – I’ve only just seen your question.)
