A few days ago, the source code for Counter Strike: Global Offensive and Team Fortress 2 was posted on several major torrent trackers. The source of the leak is believed to be someone in the entourage of Tyler McVicker, a well-known insider. This can be seen from the fact that his correspondence with several people who work at Valve was posted along with the game builds.
There is a risk that leaked source code will complicate the fight against cheaters, as malicious players may have the opportunity to study the game code in detail and find ways to bypass security mechanisms or gain access to the computers of those who play online.
At the same time, Valve has issued a statement that the leak does not pose a threat to player safety, as the archive posted online contains game data that was current as of 2017 and already appeared online in 2018. The company emphasizes that there should be no problems with the current builds of the game , but draws the attention of players to the fact that it is safest to play on official servers.
Tyler McVicker himself said that he has already found out which of his employees caused the leak and is going to pass this data to Valve. It is possible that the leak will accelerate the game's transition to the Source 2 engine – . The developers have already mentioned such intentions earlier, but did not name specific dates.
