# ASLR Bypass Simulator

An interactive educational web application for learning ASLR (Address Space Layout Randomization) bypass techniques. This simulator provides a safe, client-side environment to understand memory exploitation concepts used in offensive security.

## Features

- **5 Progressive Levels**: From basic format string leaks to complete ROP chain exploitation
- **Interactive Visualizations**: Real-time memory layout, stack, and heap visualizations
- **100% Client-Side**: No backend required, all simulations run in the browser
- **Safe by Design**: No real code execution, pure JavaScript simulation

## Levels

1. **Format String Info Leak** - Learn to leak memory addresses using printf vulnerabilities
2. **Partial Overwrite** - Exploit page-aligned addresses to bypass ASLR with minimal writes
3. **Brute Force (32-bit)** - Understand why 32-bit ASLR is vulnerable to brute forcing
4. **Heap Spray** - Fill memory with payloads to increase exploitation probability
5. **GOT/PLT Leak + ROP** - Complete exploitation chain with GOT leaks and ROP chains

## Tech Stack

- React 18 + TypeScript
- Vite for fast development and builds
- Tailwind CSS for styling
- No external runtime dependencies

## Getting Started

```bash
# Install dependencies
npm install

# Start development server
npm run dev

# Build for production
npm run build

# Preview production build
npm run preview
```

## Security

This application is designed with security as a priority:

### What This Simulator Does NOT Do
- No real memory manipulation
- No actual code execution
- No network requests for exploitation
- No eval() or Function() usage
- No dangerouslySetInnerHTML without sanitization

### Recommended CSP Headers for Deployment

```
Content-Security-Policy:
  default-src 'self';
  script-src 'self';
  style-src 'self' 'unsafe-inline' https://fonts.googleapis.com;
  font-src 'self' https://fonts.gstatic.com;
  img-src 'self' data:;
  connect-src 'self';
  frame-ancestors 'none';
  base-uri 'self';
  form-action 'self';
```

### Input Sanitization

All user inputs are sanitized:
- Format strings are validated and dangerous specifiers (%n) are blocked
- Hex inputs are validated for format
- Length limits prevent DoS
- HTML entities are escaped for display

## Educational Purpose

This simulator is intended for:
- Security researchers learning exploitation techniques
- CTF players practicing pwn challenges
- Developers understanding vulnerabilities to write secure code
- Students studying computer security

**All techniques demonstrated are for educational and defensive purposes only.**
