Cybersecurity firm Tesorion has released a free decryptor for the ThunderX ransomware that allows victims to recover their files.

ThunderX is ransomware that appeared in the threat landscape recently, infections were discovered at the end of August 2020. 

Researchers developed a decryptor for the ransomware after they have discovered a bug in the encryption process implemented by the threat.

This decryptor can recover for free files encrypted by the current version of the ThunderX ransomware that appends the .tx_locked extension to the filename of the decrypted files.

In order to recover the files, victims have to upload a copy of the readme.txt ransom note and an encrypted file to receive a decryption key.


The decryptor can be downloaded from the website of the NoMoreRansom project that already has helped victims of multiple ransomware to save more than one hundred million of ransom.

When the decryption process is completed, the decryptor will show a summary of the files successfully and those once for which the recovery failed.
