A decryptor for the Tortilla variant of the Babuk ransomware has been  released  by Cisco Talos, allowing victims targeted by the malware to regain access to their files. The cybersecurity firm said the threat intelligence it shared with Dutch law enforcement authorities made it possible to arrest the threat actor behind the operations. The encryption key has also been shared with Avast, which had previously  released a decryptor  for Babuk ransomware after its  source code was leaked  in September 2021.

This has raised the possibility that the Black Basta developers either cut out affiliates from the chain a...
