# Exploiting Type Confusion Bugs

## Overview

Exploit type confusion vulnerabilities where objects are accessed through incompatible types, enabling arbitrary read/write and code execution in compiled applications.

## Prerequisites

| Tool / Requirement | Details |
|---|---|
| `gdb` | Security tooling |
| `ghidra` | Security tooling |
| `pwntools` | Security tooling |
| GDB, Ghidra for reverse engineering, understanding of C++ vtables | Environment requirement |

## Quick Reference

```bash
# Quick start commands
node scripts/agent.js --help
node scripts/agent.js analyze --binary ./target --check type-confusion
```

## Workflow

### Step 1: Identify Type Confusion

```bash
node scripts/agent.js analyze --binary ./target --check type-confusion
```

### Step 2: Map Object Layouts

```bash
node scripts/agent.js map --binary ./target --class TargetClass
```

### Step 3: Exploit Confused Type

```bash
node scripts/agent.js exploit --binary ./target --fake-obj layout.json
```

**Detection Opportunities**

| Indicator | Source | Detection Logic |
|---|---|---|
| Exploiting Type Confusion Bugs Detection | windows/process_creation | Sigma rule (critical) |
| ATT&CK Coverage | MITRE ATT&CK | T1203 |

## Verification

- **Verify type confusion**: `node scripts/agent.js analyze --binary ./target --check type-confusion`
- **Confirm exploitation**: `node scripts/agent.js exploit --binary ./target --fake-obj layout.json`
