# Analyzing Websocket Security

## Overview

Analyze WebSocket security including origin validation, authentication on upgrade, message injection, cross-site WebSocket hijacking (CSWSH), and data exposure risks.

## Prerequisites

| Tool / Requirement | Details |
|---|---|
| `burpsuite` | Security tooling |
| `wscat` | Security tooling |
| `zap` | Security tooling |
| Burp Suite with WebSocket support, wscat, target WebSocket endpoint | Environment requirement |

## Quick Reference

```bash
# Quick start commands
node scripts/agent.js --help
wscat -c ws://target.com/ws -H 'Origin: https://evil.com'
```

## Workflow

### Step 1: Intercept WS Handshake

```bash
wscat -c ws://target.com/ws -H 'Origin: https://evil.com'
```

### Step 2: Test CSWSH

```bash
node scripts/agent.js test --url ws://target.com/ws --vector cswsh
```

### Step 3: Analyze Message Format

```bash
node scripts/agent.js analyze --url ws://target.com/ws
```

## Detection

```yaml

**Detection Opportunities**

| Indicator | Source | Detection Logic |
|---|---|---|
| Websocket Security Detection | windows/proxy | Sigma rule (medium) |
| ATT&CK Coverage | MITRE ATT&CK | T1071.001 |

## Verification

- **Verify WS analysis**: `node scripts/agent.js analyze --url ws://target.com/ws`
- **Confirm CSWSH finding**: `node scripts/agent.js test --url ws://target.com/ws --vector cswsh`
