Activision is investigating game-breaking exploits in the recently released PlayStation 4 and PlayStation 5 ports of Call of Duty: Black Ops 1 and 2. According to reporting by IGN, modders are using outdated encryption from the original PS3 versions to manipulate save files, allowing players to bypass progression systems and rank up rapidly in online lobbies.
Legacy Encryption Vulnerabilities in PS4 and PS5 Ports
The current security breach stems from a failure to update file encryption during the porting process. A modder interviewed by YouTuber Tdawgsmitty explained that the save data for the new versions is identical to the PS3 version. This allows users to copy save files to a USB drive and use third-party websites to unencrypt the data.
According to the modder, the process requires a jailbroken PS4 or PS5 to decrypt the files. The source explicitly blamed Iron Galaxy and Activision for not changing the encryption on the files, stating that this oversight is the “only reason” the exploits are currently available.
Did you know? While stats and ranks are being manipulated, the modder told Tdawgsmitty that aimbots—which automate killing other players—are not currently present in these ports.
Activision Response and Lobby Stability
The influx of exploiters led some players to describe the game as “unplayable” shortly after launch. In response, Activision removed specific playlists to mitigate the impact of modded lobbies. The company confirmed to Tdawgsmitty that it is actively investigating the issues to find a resolution.
Beyond individual modding, a secondary market has emerged. The modder noted that individuals are now selling services to other players to artificially inflate their stats and modify their game profiles, further destabilizing the competitive integrity of the multiplayer experience.
Comparison: Port Features vs. Security
| Feature | Status in PS4/PS5 Port |
|---|---|
| Visual/Performance Upgrades | None significant |
| Encryption Security | Identical to PS3 (Vulnerable) |
| Progression System | Compromised via save-file editing |
