"What you see superficially about the coder scene is just the tip of the iceberg," says Supex0. Through dispute, Flame and stronger competitive thinking in the scene, many coders have withdrawn and exchange only in small groups. Above all, these are coders who are looking for a cheat challenge and do not want to earn as much money as possible. "Many coders in the core scene do it all for fun and spend weeks looking for gaps in the game, which they sometimes use more or less creatively for their cheats, their cheats they pass on only in the small circle of acquaintances," explains one Cheat coders. These types of cheats are called private cheats or k01n hacks and are especially attractive for professional players.
Wallhacks in competitive gaming
Professional Counter-Strike players know exactly how to use their cheats so that they do not attract the attention of the audience. They cheat - as it is called in the scene - legit: Aids (Aimbot and Aimlock) are set very weak and only reach when the crosshairs are actually in the vicinity of the opponent. So it seems as if the player just has a good day. So-called visuals are not used at all. This would include, for example, Wallhacks, where players or their outlines are colorful behind walls. They are just way too obvious.
Since even experts on the basis of game scenes can not detect whether cheats are used, remain alone anti-cheat programs to expose fraudsters. "Anti-cheat applications basically work like anti-virus programs," explains Marcel Menge from Turtle Entertainment in an interview with Golem.de. He is working on the anti-cheat program of the ESL.
Also Valve itself has an anti-cheat system for Counter-Strike Global Offensive: the VAC-Detection. "VAC is mainly based on a blacklist and a few other detection mechanisms," Ko1n explains. The manufacturers do not like to talk about anti-cheat applications because they do not want to explain the mechanisms in order not to create new attack possibilities. So mainly known cheats are detected. For normal matchmaking, the system is sufficient, as the cheats of the major providers are banned in regular waves. Unknown, private cheats remain largely undetected.
