GhostHook is a new attack technique which allows hackers to bypass kernel protections of Windows 10 PatchGuard and plant rootkits within systems. PatchGuard is a software tool that has been designed to forbid the kernel of 64-bit versions of Windows operating systems from being patched, preventing attackers from executing malicious code or running rootkits at the kernel level. According to the researchers at CyberArk, GhostHook is neither an elevation nor an exploitation technique but a post-exploitation attack where the attacker has control over the compromised system. It provides the hacker with the ability to hook almost any piece of code running on the system.
