CD Projekt Red was the target of a ransomware attack that encrypted devices on their network and led to the theft of unencrypted files. The attack was conducted by a ransomware group that goes by the name ‘HelloKitty,’ and yes, that’s the name the threat actors utilize. The HelloKitty operation has been active since November 2020 and has targeted other large companies, such as the Brazilian power company CEMIG last year. The ransom note is a Tor dark web URL that victims can visit to negotiate with the attackers.
