Similarly, the technique, while itself blocked by HVCI from writing to PspServiceDescriptorGroupTable , demonstrates how attackers continue developing novel approaches to kernel manipulation that force security researchers to evolve countermeasures.
: Users may seek to turn off HVCI to improve system performance or resolve compatibility issues with older drivers. Hvci Bypass
The question isn't whether HVCI can be bypassed—it's whether organizations are prepared to detect and respond when it is. Similarly, the technique, while itself blocked by HVCI
) protections. A memory page in the kernel can be writable, or it can be executable, but . ) protections
: Kernel Pack's latest version introduced DOG, a post-exploitation toolkit that achieves kernel-level access without loading custom drivers. This driverless approach bypasses modern kernel protections like PatchGuard, HVCI, and VBS by manipulating data rather than hijacking control flow.
Hypervisor-Protected Code Integrity has successfully raised the cost of kernel exploitation, forcing attackers to abandon simple driver loaders in favor of elaborate signed-driver abuse or configuration downgrades. The public research landscape from 2024 to 2026 demonstrates that while HVCI is far from perfect, breaking it requires either sophisticated physical memory primitives or logical flaws in Microsoft's update infrastructure.
