This bug, known since 2019 and reported to Valve, is one of the new finds of hackers to take possession of your computer.
This is actually a flaw in the Source game engine developed by Valve. Many games rely on this graphics engine, but they no longer seem to be affected by it, unlike Counter-Strike: Global Offensive.

Well-meaning hackers
To exploit this flaw, hackers use Steam's invitation system. By clicking on the invitation to play the game, the victim can have private information taken from them and see their hard drive infected. This intrusion can also affect other members present in the CS:GO lobby.
Discovered by The Secret Club, a well-meaning group of hackers, this flaw was reported to Valve in 2019, but continues to plague.
It was via the HackerOne platform that Florian, one of the members of the group behind the report, contacted Valve about this flaw. Finally stamped as "critical" by the development studio, Florian reveals that, during its exchanges with the company, Valve said it was aware of the slowness it had shown in processing the report.
A flaw that is all the more worrying because Valve has not yet announced a patch while CS:GO, which went free-to-play in 2018, remains just as popular on Steam.
