# Exploiting Race Conditions In Binaries

## Overview

Exploit TOCTOU and race condition vulnerabilities in binaries to bypass security checks, escalate privileges, and corrupt shared state through concurrent access.

## Prerequisites

| Tool / Requirement | Details |
|---|---|
| `gdb` | Security tooling |
| `strace` | Security tooling |
| `pwntools` | Security tooling |
| GDB, strace, multi-threaded debugging capability, target binary | Environment requirement |

## Quick Reference

```bash
# Quick start commands
node scripts/agent.js --help
strace -f -e trace=open,access,stat ./target
```

## Workflow

### Step 1: Identify Race Windows

```bash
strace -f -e trace=open,access,stat ./target
```

### Step 2: Exploit TOCTOU Gap

```bash
node scripts/agent.js exploit --binary ./target --race-type toctou
```

### Step 3: Verify Privilege Escalation

```bash
node scripts/agent.js verify --binary ./target
```

**Detection Opportunities**

| Indicator | Source | Detection Logic |
|---|---|---|
| Exploiting Race Conditions In Binaries Detection | windows/process_creation | Sigma rule (critical) |
| ATT&CK Coverage | MITRE ATT&CK | T1068 |

## Verification

- **Verify race window**: `node scripts/agent.js analyze --binary ./target`
- **Confirm exploitation**: `node scripts/agent.js exploit --binary ./target --race-type toctou`
