Cyberpunk 2077 source code reportedly stolen
CD Projekt RED has announced that it has become the victim of a serious “targeted cyber attack,” with an unknown person or persons having stolen private data from the Polish developer’s servers.
CDPR has noted that it has full backups of all of the stolen data, which is believed to include the source code to the studio’s recent releaseCyberpunk 2077, code for an unreleased edition ofWitcher 3, as well as “documents relating to accounting, administration, legal, HR, investor relations and more.” CDPR has said that – to the best of its knowledge – no data involving players’ personal information is at risk.
In a surprising move, CDPR also released a copy of the “ransom note” it received from the hacker(s), requesting that CDPR contact the individual(s) responsible or face public release of the hacked documents, source code, and other data files. CDPR has said it will “not give in to the demands nor negotiate with the actor, being aware that this may eventually lead to the release of the compromised data.”
The studio is currently investigating the security breach with the help of its IT analysts, law enforcement officials, and the President of the Personal Data Protection Office.
