Overview

nullsec-injector is a process memory injector and code execution tool written in Odin. Combines low-level memory access with a clean, modern syntax for reliable shellcode and DLL injection.

Features

💉 Shellcode Injection - Multiple injection techniques
📚 DLL Injection - Remote DLL loading
🧵 Thread Hijacking - Existing thread manipulation
🔄 Process Hollowing - Replace process memory
🎭 APC Injection - Asynchronous procedure calls
📋 Module Enumeration - List loaded modules

Requirements

Odin compiler (latest)
Linux or Windows
Root/Administrator privileges

Installation

# Clone repository
git clone https://github.com/bad-antics/nullsec-injector.git
cd nullsec-injector

# Build
odin build injector.odin -out:injector

# Or run directly
odin run injector.odin

Usage

# Shellcode injection
./injector inject -p 1234 -s shellcode.bin

# DLL injection
./injector dll -p 1234 -d payload.dll

# Thread hijacking
./injector hijack -p 1234 -s shellcode.bin

# Process hollowing
./injector hollow -t target.exe -s payload.exe

# Enumerate modules
./injector modules -p 1234

Options

Flag	Description
`-p, --pid`	Target process ID
`-s, --shellcode`	Shellcode file path
`-d, --dll`	DLL file path
`-t, --target`	Target executable
`--method`	Injection method
`-v, --verbose`	Verbose output

Injection Methods

Shellcode Injection

Classic VirtualAllocEx + CreateRemoteThread
NtCreateThreadEx (stealthier)
Thread context manipulation

DLL Injection

LoadLibrary via CreateRemoteThread
Manual mapping (no LoadLibrary)
Reflective DLL injection

Advanced Techniques

Process hollowing (RunPE)
APC injection (alertable threads)
Thread execution hijacking
