SSDT hooking is a classic technique that became significantly harder after the introduction of PatchGuard (Kernel Patch Protection, KPP) in 64-bit Windows. PatchGuard monitors the SSDT (among many other structures) and triggers a CRITICAL_STRUCTURE_CORRUPTION bug check (0x109) if it detects modification. As a result, SSDT hooking is essentially dead in 64-bit Windows. However, anti-cheats still verify SSDT integrity as a defense in depth measure.

The attacker finds a legitimate, signed driver with a vulnerability (typically a dangerous IOCTL handler that allows arbitrary kernel memory reads/writes, or that calls MmMapIoSpace with attacker-controlled parameters).The attacker loads this legitimate driver (which passes DSE because it has a valid signature).The attacker exploits the vulnerability in the legitimate driver to achieve arbitrary kernel code execution.Using that kernel execution, the attacker disables DSE or directly maps their unsigned cheat driver.Common BYOVD targets have included drivers from MSI, Gigabyte, ASUS, and various hardware vendors. These drivers often have IOCTL handlers that expose direct physical memory read/write capability, which is all an attacker needs.
