Hackers have been able to access its internal network, encrypt some devices, and collect’certain data’ from the Polish video game company. The cyberpunk 2077 developer does not believe any personal data of players or service users has been compromised.

The hackers are threatening to release the source code alongside internal legal, HR, and financial documents’if we will not come to an agreement’.

Cd Projekt says it has informed the’relevant authorities’ and forensic specialists. It has begun restoring its data from intact backups.

The attack follows the developer’s troubled launch of cyberpunk 2077. The game was almost unplayable on older consoles. Sony pulled the game from the PlayStation store and offered refunds.
