An unknown hacker named Vizor banned hundreds of Call of Duty players by exploiting a weakness in the Ricochet anti-cheat system.
Vizor discovered that Ricochet anti-cheat system was scanning players' devices for specific strings to detect cheaters, leading to false positives.
The hacker was able to send private messages containing these strings, triggering bans for the targeted players.
Activision claimed to have resolved the flaw in the anti-cheat system and restored all banned accounts, but some players remain frustrated and disappointed.
