Activision did not specify the reason for the game being removed, but social media is flooded with accounts of players experiencing hacks on their PCs after playing. A streamer named Wrioh shared a clip showing the hack in progress, with the game freezing, command line and text box windows appearing, and the desktop wallpaper changing. The text box indicated that Wrioh had been “RCEd,” hinting at remote code execution vulnerabilities exploited by hackers to install malware and take control of devices.
Call of Duty: WWII was introduced to Game Pass and the Microsoft Store in June, potentially leading to the issue at hand. According to TechCrunch, different versions of the game were added to Microsoft’s platforms, including one with an old flaw that had been fixed in other versions. As of now, the game has not been reinstated.
