April 22, 2020 Valve has responded to the leaks, and says it has “not found any reason for players to be alarmed or avoid the current builds.”
Today, source code for both Team Fortress 2 and Counter-Strike: Global Offensive has leaked to the public. Players have been afraid it will lead to a rash of new cheats and exploits – including serious security risks like remote code execution – but Valve says there’s no need to be worried.
“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,” a Valve representative tells us. “From this review, we have not found any reason for players to be alarmed or avoid the current builds (as always, playing on the official servers is recommended for greatest security). We will continue to investigate the situation and will update news outlets and players if we find anything to prove otherwise.
“In the meantime, if anyone has more information about the leak, the Valve security page describes how best to report that information.”
Popular TF2 community servers like Creators.TF and Red Sun suspended their operations earlier today pending details on the scope of the leaks. Some players have reported that malicious code is already live on TF2 servers, but none of those reports have yet been confirmed.
