For anti-cheat developers (VAC, SMAC, or third-party clients), the CS:S source code is a treasure map. Cheaters search for the source code to find "offsets"—specific memory addresses that store player positions, health values, or view angles.
The most prominent event regarding the search term "Counter-Strike source code" occurred in April 2020. The gaming community was rocked when a significant portion of the source code for Counter-Strike: Global Offensive and Team Fortress 2 was leaked online.
Valve quickly issued a statement attempting to calm the storm. They clarified that the code leaked was an older build from roughly 2017/2018. While they advised players to play on official servers (which were secure), they downplayed the immediate RCE threat.
The constant arms race revolves around Valve security patching the specific vulnerable functions inside the CS:S source base.
