In January 2023, Riot Games confirmed that its development environment was compromised in a social engineering attack. While the attackers exfiltrated the source code for League of Legends , Teamfight Tactics , and a legacy anti-cheat platform, Riot explicitly stated that in this specific breach.

: The code defines the "Authoritative Server" model, where the server validates every player action (shooting, moving, ability usage) to prevent speed hacks or teleportation cheats. The Impact on the Community
For cheat developers, the internal source code is a roadmap to vulnerabilities [3, 11]. Having access allows them to:
Code runs as a separate process and reads the game's memory from the outside. While generally harder for some anti-cheats to detect, it is often slower and less precise. 2. The Barrier: Vanguard Anti-Cheat
