Walk-through of Xyrem's reversing.info analysis of Valorant’s Vanguard Guarded Regions: how Vanguard hides game state behind a private "shadow" PML4 entry that’s only swapped in when one of its own whitelisted threads is on the CPU, the SwapContext hook that drives the swap, and how a cheat can rebuild the same primitive with its own kernel driver to expose hidden game memory after thread whitelisting. core-jmp.org/2026/06/reverse… #AntiCheat #AntiCheatArchitecture #CheatDevelopment #CR3 #GuardedRegions #KernelAntiCheat #KernelDriver #KernelDriverReverseEngineering #KernelExploitation #Paging #PML4 #ReverseEngineering #RiotVanguard #ShadowMemory #SwapContextHook #Valorant #WinDBG #WindowsKernel #WindowsReverseEngineering
