Bungie treated cheating as a launch priority. The February Server Slam doubled as an anti-cheat stress test. Five months later, cheaters still show up — so how does the system work?
Three layers
Kernel client protection
Catches known signatures and memory tampering. Public free cheats die here within days.
Server behavior analysis
Tracks impossible aim, loot paths, and stat outliers. Ban waves come in batches so devs cannot easily reverse-engineer triggers.
Player reports
Feeds the behavior pipeline. Update 1.1.5 added voice moderation too.
