In February, CD Projekt suffered a ransomware attack that allowed threat actors to steal source code and business data before encrypting devices. In a new statement published today, the company said they have learned that this stolen data is now being circulated and may include employee and contractor details. The attack was conducted by a ransomware operation known as HelloKitty, who allegedly stole the complete source code of Cyberpunk 2077, the Witcher 3, Gwent, and an unreleased Witcher 3 version.
