Right in the middle of the Summer Game Fest Kickoff Live, CD Projekt Red took to Twitter to reveal just how severe the cyberattack was against their studio. Yeah, they actually did it when everyone was distracted elsewhere, perhaps in an effort to minimize the attention brought to it. I can't say that did them a whole lot of good though.

Despite their efforts, CDPR says that they were unable to contain the data breach.

Back in February, the hackers claimed to have stolen the source code for various CDPR projects. This includes the source code for The Witcher 3: Wild Hunt and Cyberpunk 2077. The stolen data was put up for sale at a $1 million starting price. CD Projekt Red said, at the time, that no personal data of customers was stolen.

Today, CDPR revealed that additional data was stolen beyond what was initially thought. This data includes data about current and former employees and contractors. The studio just stopped short of saying what all was stolen.

Today, we have learned new information regarding the breach, and now have reason to believe that internal data illegally obtained during the attack is currently being circulated on the Internet.

We are not able to confirm the exact contents of the data in question, though we believe it may include current/former employee and contractor details in addition to data related to our games. Furthermore, we cannot confirm whether or not the data involved may have been manipulated or tampered with following the breach.
CD Projekt Red says that they are still working with authorities on this data breach.
