Since HVCI enforces integrity exclusively on (executable pages) and not on data , attackers shift their focus toward Direct Kernel Object Manipulation (DKOM).
While HVCI prevents code patching, "data-only" attacks remain a threat. The "Hell's Hollow" technique utilizes the undocumented Alternate System Call handler to hook the System Service Dispatch Table (SSDT) by manipulating the KTRAP_FRAME rather than overwriting code. However, it is critical to note that while Hell's Hollow resists PatchGuard and HyperGuard, HVCI specifically blocks writing to the PspServiceDescriptorGroupTable structure , leaving this vector mitigated. Researchers are actively exploring "pure data" SSDT Hijack primitives that hijack execution flow without touching code integrity checks. Hvci Bypass
HVCI operates by creating a virtualization-based security environment. Here’s a simplified overview of its operation: However, it is critical to note that while
In the context of technical discussions and gaming, an "HVCI Bypass" typically refers to one of two things: Here’s a simplified overview of its operation: In
