A new security vulnerability has been discovered in Grand Theft Auto Online. Spotted by Rockstar insider, evidence of the vulnerabilities have been revealed, which includes the ability for malicious users to execute code remotely in the game (via PC Gamer). The exploit currently only exists on the PC version of Grand Theft Auto Online.
The security vulnerability would essentially allow hackers to install malware on a player’s computer without their knowledge. According to Tez2, Rockstar is aware of these issues.
The exploit was first reported as giving a modder the ability to take away a player’s rank and in-game money, resetting their account in the process. An account could also be corrupted, essentially banning them from being able to play Grand Theft Auto Online.
Currently, the only real form of protection against these attacks seems to be the Guardian tool, which essentially warns a player when a modder is getting close to remote code execution. The creator of the tool, Speyedr, has warned players that Guardian may not be the best form of defense against these hacks.
