Call of Duty has temporarily taken its PC games offline due to reports of remote code execution (RCE) attacks that have compromised players' computers. The developers are investigating the issue. Players have shared videos of their systems being hacked during gameplay, with incidents including game freezes and unauthorized command executions. The vulnerability is linked to the shift from dedicated servers to peer-to-peer networking, which has made older games more susceptible to attacks. MalwareBytes has noted that this issue has become well-known in the community, leading many to avoid these titles. Previous vulnerabilities allowing RCE through the Steam platform were identified six years ago. The official Call of Duty X account has not provided updates on the investigation or the status of the games.
