The Egregor ransomware operators have published archives containing data allegedly obtained from internal networks of the major gaming companies, Ubisoft and Crytek, in two unrelated attacks. Data supposedly stolen from the two companies was posted on the group’s leak site, with threats from the Egregor gang to leak more files in the coming days.

At a present, it is unknown how the ransomware gang has managed to steal the data. While there is no sufficient evidence the Ubisoft hack is legitimate, sources told BleepingComputer that Crytek was indeed hit by the Egregor ransomware that encrypted the company’s files adding the '.CRYTEK' extension to them.

Additionally, the Egregor gang claims they have stolen unencrypted files from Crytec and posted a 380MB archive on their dark web portal. The data contains files related to WarFace, Crytek's canceled Arena of Fate MOBA game, and their network operations.

The Egregor ransomware operators also claim they have compromised Ubisoft's network and obtained unencrypted data, including the source code for the upcoming Watch Dogs: Legion game. On the leak site the gang has shared a 20MB archive with game assets that are allegedly part of Ubisoft's Watch Dogs game.

Neither Ubisoft nor Crytek did not provide any statements regarding the incident.
