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
