As Windows security hardens, traditional "Easy Mode" exploits (like simply loading a malicious driver) no longer work. An HVCI bypass is the "Holy Grail" for several groups: Hvci Bypass

HVCI is a Windows feature that utilizes the Windows Hypervisor, also known as the Windows Subsystem for Hyper-V, to create a secure execution environment. This environment ensures the integrity of kernel-mode code, making it difficult for attackers to inject malicious code into the Windows kernel. This environment ensures the integrity of kernel-mode code,

Whoever wrote this wasn't a thief. They were a cartographer, mapping the last unmapped territory: the hypervisor’s blind spot. And now they knew the way. And now they knew the way
