A free master decryptor for the REvil ransomware operation has been released, allowing all victims encrypted before the gang disappeared to recover their files for free.
The REvil master decryptor was created by cybersecurity firm Bitdefender in collaboration with a trusted law enforcement partner.
While Bitdefender could not share details about how they obtained the master decryption key or the law enforcement agency involved, they told BleepingComputer that it works for all REvil victims encrypted before July 13th.
"As per our blog post, we received the keys from a trusted law enforcement partner, and unfortunately, this is the only information we are at liberty to disclose right now," Bitdefender's Bogdan Botezatu, Director of Threat Research and Reporting, told BleepingComputer.
"Once the investigation progresses and will come to an end, further details will be offered upon approval."
REvil ransomware victims can
download the master decryptor from Bitdefender (
instructions) and decrypt entire computers at once or specify specific folders to decrypt.
