Since generating new executable code is restricted, advanced exploits rely on stitching together existing, signed code snippets (gadgets) already residing in the kernel.

The discovery and exploitation of HVCI bypasses is not new; it is a long-standing trend that has intensified in recent years. The journey of these vulnerabilities highlights the ongoing cat-and-mouse game between Microsoft's security team and the security research community. The journey of these vulnerabilities highlights the ongoing

While bypasses exist, organizations and security researchers are not defenseless. Understanding attack vectors allows for hardening beyond default Microsoft configurations.

While HVCI provides strong protection, it is not infallible. Several techniques exist to circumvent its protections, mostly focusing on exploiting weaknesses in the driver signing chain or finding gaps in the memory verification process.
