German programmer Tobias Frömel (aka “battleck”) has “hacked back” the perpetrators of the Muhstik ransomware who forced him to pay 0.09 Bitcoin (BTC) to recover access to his files.
In a Bleeping Computer forum post on Oct. 7, Frömel revealed that he had hacked the attackers’ database, sharing almost 3,000 decryption keys and a free decryptor with fellow victims.
