Activision released another set of backend updates for Call of Duty: Black Ops II on PS4 and PS5 as it works to protect multiplayer matches from a hacker who altered player accounts.
Players had reported finding manipulated accounts in their lobbies, including profiles pushed to Prestige levels that do not exist in the game. Some affected players also encountered crashes that stopped them from returning to multiplayer.
In a post from the Call of Duty Updates account, Activision said the changes were intended to “improve match security” while it reviews accounts with incorrect Prestige levels.
📢 Call of Duty: #BlackOps2 on PS4/PS5
We've released backend updates to improve match security as we review accounts with incorrect Prestige levels.
While this work is underway, some players may briefly see an account ban notice when they're removed from a match or session so…

Temporary ban notices may appear
Activision warned that some players could see a ban notice when the system removes them from a match or session. According to the warning, that message may only appear while older systems process updated account data.
Players who can reconnect after seeing the notice should have had their accounts processed without further action. Those who cannot reconnect may have been flagged for enforcement because of unauthorized Prestige levels or other violations involving account manipulation.
The clarification separates players who were affected by someone else’s actions from those who intentionally obtained altered progression. Activision said the account review is still in progress.
Reports from affected players suggest the fix has not resolved every case. Some said their account changes remained in place, while others said they had already reset their statistics themselves and were unable to restore the progress they had before the manipulation. Players can still matchmake across the PS4 and PS5 versions, as Activision previously confirmed in its clarification about the two PlayStation ports.
Other player reactions also questioned whether the backend work addressed the person or exploit responsible for the attacks. One response said the situation had not inspired confidence that the underlying problem was fixed, while another reported that an affected account had not changed after the update.
For now, players who encounter a suspicious lobby or a temporary ban notice should avoid assuming that their account has been permanently banned. The message may disappear after reconnecting, but accounts identified for intentional manipulation can still face enforcement.
