After Two Years, Valve Has Finally Fixed A Major Exploit Within Counter-Strike: Global Offensive

It's been out for nearly a decade, but even now, Counter-Strike: Global Offensive still receives regular updates from Valve. Having cultivated a successful eSports scene, it turns out that CS:GO was also home to a worrying PC exploit.


First discovered by a non-profit reverse-engineering group, The Secret Club, this involved a remote code execution flaw, making it possible for hackers to take over their target's PC by getting them to accept a CS:GO Steam invite.

After Two Years, Valve Has Finally Fixed A Major Exploit Within Counter-Strike: Global Offensive

The Secret Club claims they made Valve aware of this two years ago, crediting group member Florian for discovering it, but no action was taken until they went public. Reportedly, this exploit can affect any Source Engine games, though only CS:GO and Team Fortress 2 are have known issues, with the latter still awaiting a fix.

Frustrations were evidently high after two years, and when speaking through Vice's Motherboard, Florian told us: "Valve's response has been a complete disappointment right from the start. Our experience has always been slow response times, with little to no patches being pushed to production. They truly don't care about the security and integrity of their games."

Since that initial tweet, they've since confirmed that Valve has finally fixed this exploit, meaning players can put their minds at ease. Florian's now working on a full technical write up about it, and we can expect that soon.
