Anyone digging into current kernel-mode persistence lately? The landscape is getting progressively tighter with HVCI and KPP (PatchGuard) constantly evolving.
I am weighing the trade-offs between legacy manual DSE bypasses—specifically patching g_cioptions—and the more recent reliance on BYOVD (Bring Your Own Vulnerable Driver) patterns for mapping unsigned modules.
From my testing, manual patching remains a cat-and-mouse game against PatchGuard's integrity checks. Every time you touch CI structures or attempt to drop a kernel-mode hook, the heartbeat checks eventually trigger an exception if not properly handled via hypervisor stealth or callback manipulation.
BYOVD feels cleaner on the surface, but the recent telemetry updates on common vulnerable drivers have turned the attack surface into a minefield. You are essentially broadcasting your intentions to any modern anti-cheat monitor as soon as a known vulnerable handle is opened.
Have you guys found a more reliable way to maintain persistence without tripping these modern integrity gates? Curious if anyone is successfully leveraging hypervisor-level hooks to bypass the CI constraints entirely without a manual DSE patch.

- Manual DSE Patching: Requires stable kernel primitives and constant monitoring of PatchGuard's DPC routines to prevent BSODs.
- BYOVD: High risk of detection due to driver signature blacklists and enhanced behavior monitoring of MmMapIoSpace.
- HVCI Compatibility: Most legacy exploits fall apart the moment Hypervisor Protected Code Integrity kicks in, restricting the execution of unsigned code entirely.
