Overview
- Activision released backend updates this week to improve match security and to review accounts showing incorrect Prestige levels after the PS4/PS5 ports launched in July.
- Hackers have been able to force players into non‑existent Prestige levels, reset ranks, lock features, crash sessions and in some cases 'brick' accounts by manipulating lobby data.
- The publisher warned players that a temporary 'account banned' notice may appear when systems apply updated account data and said reconnecting means the account was processed successfully.
- Players report mixed results from the rollout and Activision has not committed to automatically restoring accounts that were unfairly flagged or suspended after encountering hackers.
- The problem traces to legacy server and account systems used by older Call of Duty titles and involves Activision, Treyarch and port developer Iron Galaxy as the parties working on further fixes, which could require more patches to stop repeat attacks.
