Earlier today, it was reported that the source code for both Counter-Strike: Global Offensive and Team Fortress 2 has been leaked online. Some claimed that this leak could lead to malware finding their way on players’ systems, however, that’s not the case. Valve has confirmed that both CS:GO and TF2 are safe, provided you play on official servers.
Valve claims that this leak is from an engine code depot that was available to partners in late 2017. Not only that, but this source code was originally leaked in 2018, so this isn’t a new leak.
As Valve stated via the official Twitter accounts for both Counter-Strike: Global Offensive and Team Fortress 2.
We have reviewed the leaked code and believe it to be a reposting of a limited CS:GO engine code depot released to partners in late 2017, and originally leaked in 2018. From this review, we have not found any reason for players to be alarmed or avoid the current builds.

From our review, we have not found any reason for TF2 players to be alarmed or avoid the current builds (as always, playing on the official servers is recommended for greatest security).

So there you have it everyone, straight from the horse’s mouth. If you are playing on official servers, you won’t get any malware.

even more reason to update CSGO to source2 all ready!
I’m more concerned as to how people are still playing these two disgustingly outdated piles of garbage.
CSGO is still better (mechanically) than anything else on the market, there is no truer gun vs gun game, and its not about graphics.
For me any FPS that doesn’t include iron sights mechanic for all weapons, isn’t a true FPS. I respect CS and it’s history, but you still would want to aim through these irl.
Why would you need iron sights for all weapons in games like Doom or Serious Sam?
trash opinion
What a narrow view for a FPS player…what’s next? you play FPS with a gamepad? that’s why you need iron sights? to mask the auto aim?
Quake and UT games.
Insurgency Sandstorm
cuz CSGO is still better then any other game
this happened because of a transeexual sjw who got a guy fired.
Rip valve.
wow seriously ??
yup
Well that’s stunning and brave… I don’t play Valve MP games anymore, but i feel bad for the people playing them…
last time someone said don’t worry it was my girlfriend then a day after that i saw her with my best friend, just saying.
*Epic Bruh Moment*
Well, it’s time to port CSGO and TF2 to Source 2, they were going to do it one day or another so here’s a reason to do it now
“no reason to worry”
Wrong !! If you play these games online, you should stop ASAP
port your game already the optimization its horrible for newer CPU’s
Good thing i waste my time with other games…i’m still waiting for the Source 2 CS…
