CD Projekt Red released a statement on Twitter today noting that the company has been the victim of a cyber attack. The ransom note was released to the public alongside the announcement, and it claims that the hackers have "dumped full copies of the source codes" for Cyberpunk 2077, Witcher 3, Gwent and "the unreleased version of Witcher 3," presumably the next-gen edition coming later this year.

According to CD Projekt, devices on its network have been encrypted, but they have begun restoring their IT infrastructure and data through backups. "We 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 company's Twitter statement reads. CD Projekt Red says that to the best of its knowledge, "the compromised systems did not contain any personal data of our players or users of our services."
