Counter Strike' Bug Allows Hackers To Take Over a PC With a Steam Invite

Hackers could take control of victims' computers just by tricking them into clicking on a Steam invite to play Counter Strike: Global Offensive, Motherboard reports, citing a bug filing review. From a report: A bug in the game engine used in Counter Strike: Global Offensive could be exploited by hackers to take full control of a target's machine. A security researcher alerted Valve about the bug in June of 2019. Valve is the maker of Source Engine, which is used by CS:GO, Team Fortress 2, and several other games. The researcher, who goes by the name Florian, said that while that the bug has been fixed in some games that use the Source engine, it is still present in CS:GO, and he demonstrated it in a call with Motherboard. Florian's correspondence with Valve occurred on HackerOne, the bug bounty platform used by the company to get reports about vulnerabilities. Valve admitted that it was being slow to respond, even though it classified the bug as "critical" in the thread with the researchers, which Motherboard reviewed. "I am honestly very disappointed because they straight up ignored me most of the time," Florian said in an online chat.
