Call of Duty: Black Ops 1 and 2 were released this month for PlayStation 4 and PlayStation 5, but players have reported that multiplayer lobbies are being disrupted by hackers exploiting vulnerabilities in the games' anti‑cheat systems. The re‑release utilizes updated servers, yet the underlying anti‑cheat software has not been upgraded, allowing longstanding exploits such as aimlock, ESP wallhacks and tools that modify experience points to be used across the new platforms. Some users said they have received negative XP, which prevents progression to level 1, and others have observed accounts being boosted to maximum level without their consent. The issues, which have existed on earlier console and PC versions, were expected according to multiple player reports. Activision has not confirmed plans to update the anti‑cheat system. In the meantime, players are advised to avoid online matches with high‑level opponents and to leave lobbies that show signs of cheating, such as frequent grenade suicides or rapid player turnover. The problem may affect the viability of the multiplayer experience until the anti‑cheat is improved.
