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.
