HVCI has fundamentally changed the landscape of Windows security. It has moved the goalposts from simple code execution to complex, data-oriented programming and hardware-level exploitation. While no system is unhackable, the barrier to entry for an is now so high that it is largely the domain of advanced persistent threats (APTs) and high-level security experts.
Hypervisor-Protected Code Integrity (HVCI), or , is a hardware-enforced security boundary that prevents unauthorized code from running in the Windows kernel. Bypassing it is a complex task that targets the "Secure World" created by Virtualization-Based Security (VBS). The Architecture: Why HVCI is Hard to Kill Hvci Bypass
Modern CPUs use hardware-based shadow stacks to prevent ROP attacks. HVCI has fundamentally changed the landscape of Windows
