Overview

nullsec-memcorrupt is a memory corruption exploitation toolkit written in Zig. Leverages Zig's comptime features and memory safety controls for precise exploit development with zero runtime overhead.

Features

• 🔴 Heap Exploitation - Use-after-free, double-free, heap overflow
• 📚 Stack Attacks - Buffer overflow, ROP chain builder
• 🎯 Format Strings - Automated format string exploitation
• 🔧 Gadget Finder - ROP/JOP gadget discovery
• 💉 Shellcode Gen - Position-independent code generation
• 🛡️ Bypass Tools - ASLR, NX, canary, RELRO defeat

Requirements

• Zig 0.11+
• Linux x86_64 (primary target)
• GDB/LLDB (for debugging)

Installation

git clone https://github.com/bad-antics/nullsec-memcorrupt.git
cd nullsec-memcorrupt
zig build -Drelease-fast

Usage

# Find ROP gadgets
./memcorrupt gadgets -f ./vulnerable_binary

# Generate exploit template
./memcorrupt template -t stack_bof -o exploit.zig

# Analyze binary protections
./memcorrupt checksec -f ./binary

# Build ROP chain
./memcorrupt rop -f ./binary --goal execve

# Format string calculator
./memcorrupt fmtstr -offset 6 -target 0x404040 -value 0xdeadbeef
