🧪 NtQueueApcThreadEx NTDLL Gadget Injection Introduction This novel way of using NtQueueApcThreadEx by abusing the ApcRoutine and SystemArgument0-3 parameters by passing a random pop r32; ret gadget can be used for stealthy code injection. Within this PoC, the gadget in this case is picked random...

NyxInvoke
NyxInvoke NyxInvoke is a versatile Rust-based tool designed for executing .NET assemblies, PowerShell commands/scripts, Beacon Object Files BOFs and PE files with built-in Ntdll Unhooking, patchless AMSI and ETW bypass capabilities. It can be compiled as either a standalone executable or a DLL...
NTDLL-Unhook
NTDLL Unhook proper ntdll .text section unhooking via native api. x86/x64/wow64 supported. How It Works The program walks the PEB to locate ntdll.dll base address and manually parses the PE export table to resolve NT API functions without touching the Import Address Table. It then uses NtOpenFile...

NTDLL-reconstruction
NTDLL-reconstruction A userland EDR bypass technique that allows you to flip between unhooked and hooked ntdll.dll at will. How I built this can be found here. Usage You can just drag and drop the .h and .c file into your project make sure you edit the header file definition for CRT functions tha...
HallWatch
HallWatch Copyright C 2026 Adam Zypherion — licensed under GPL-3.0. Indirect syscalls are simple once you have seen one. The loader walks ntdll, reads the SSN out of Nt prologue, finds the 0F 05 two bytes further in, sets r10/rax/rdx/r8/r9 itself, and jmps straight at those two bytes. The syscall...
RefleXXion
Introduction RefleXXion is a utility designed to aid in bypassing user-mode hooks utilised by AV/EPP/EDR etc. In order to bypass the user-mode hooks, it first collects the syscall numbers of the NtOpenFile, NtCreateSection, NtOpenSection and NtMapViewOfSection found in the LdrpThunkSignature arra...
stealth_call
What is this? Header-only library for Windows x64 that lets you invoke any NT syscall without touching ntdll imports, without leaving strings in your binary, and without the usual red flags that make EDRs lose their minds. No CRT. No STL. No IAT. The whole thing compiles down to 19KB with literal...

CallstackSpoofingPOC
Callstack spoofing + Indirect Syscalls POC This project consists of a simple C++ self-Injecting dropper focused on EDR evasion POC. To implement it, I have combined the use of Windows Thread Pooling to hide the call stack and the use of indirect syscalls to avoid hooking in the NTDLL...
