Call of Duty: Black Ops 2’s PlayStation versions have reportedly been compromised by a hacker who can disrupt matches and damage players’ accounts. The issue matters because it affects an older but still active online game, leaving players vulnerable to unwanted account changes and potentially discouraging them from using its multiplayer modes.

Reports say the hacker can alter players’ statistics and unlocks, including resetting progress or applying high levels and prestige ranks without permission. The problem is said to affect the PlayStation 3 and PlayStation 4-compatible versions, while there is no confirmed fix or response from publisher Activision in the article.
