Excerpt

WebSocket Security Testing

Objective

Exploit WebSocket implementation flaws including cross-site WebSocket hijacking (CSWSH), message injection, and authentication bypass.

Testing Methodology

Phase 1: Identify WebSocket Endpoints

# Look for WebSocket upgrade
curl -s -D- https://TARGET/ -H "Upgrade: websocket" -H "Connection: Upgrade"

# Check common paths
for path in /ws /socket /websocket /api/ws /chat /live /realtime; do
  curl -s -D- "https://TARGET$path" \
    -H "Upgrade: websocket" \
    -H "Connection: Upgrade" \
    -H "Sec-WebSocket-Version: 13" \
    -H "Sec-WebSocket-Key: dGhlIHNhbXBsZSBub25jZQ==" 2>/dev/null | head -1
done
