Bypassing Windows Kernel Mitigations: A Deep Dive into Violet Phosphorus
2024-12-13
This post delves into bypassing modern Windows 10 and 11 kernel mitigations like SMEP and VBS. The author details Violet Phosphorus, a universal VBS/SMEP bypass technique, providing PoC code and a ROP chain. It explains SMEP and VBS, demonstrating how to exploit a vulnerability in the HackSysExtremeVulnerableDriver to use ROP gadgets and the MiGetPteAddress function to modify page table entries for kernel code execution. The author also shows how to use Kristal-G's SYSRET shellcode to return to user mode. This is a valuable resource for kernel exploit development and security researchers, categorized as Development.
