Exploiting Websocket Vulnerabilities

Overview

Cybersecurity skill for exploiting websocket vulnerabilities. Follows industry best practices and security standards.

When to Use

Trigger phrases:

• "exploiting websocket vulnerabilities"

• "Testing WebSocket implementations for authentication bypass, cross-site hijackin"

• During authorized penetration tests when the application uses WebSocket connections for real-time features

• When assessing chat applications, live notifications, trading platforms, or collaborative editing tools

• For testing WebSocket API endpoints for authentication and authorization flaws

• When evaluating real-time data streams for injection vulnerabilities

• During security assessments of applications using Socket.IO, SignalR, or native WebSocket APIs

When NOT to Use

• When you lack proper authorization for testing
• For production systems without change management
• When the task requires legal or compliance expertise beyond technical scope

Prerequisites

• Authorization: Written penetration testing agreement covering WebSocket testing
• Burp Suite Professional: With WebSocket interception capability
• Browser DevTools: Network tab for WebSocket frame inspection
• websocat: Command-line WebSocket client (cargo install websocat)
• wscat: Node.js WebSocket client (npm install -g wscat)
• Python websockets: For scripting custom WebSocket attacks (pip install websockets)

Workflow

# Example: IOC detection
import re

IOC_PATTERNS = {
    "ip": r"\b(?:\d{1,3}\.){3}\d{1,3}\b",
    "domain": r"\b[a-z0-9-]+\.[a-z]{2,}\b",
    "hash_md5": r"\b[a-f0-9]{32}\b",
    "hash_sha256": r"\b[a-f0-9]{64}\b",
}

def extract_iocs() -> :
     {k: re.findall(v, text)  k, v  IOC_PATTERNS.items()}
