A network firewall that blocks WebSocket hijack attacks on local OpenClaw agents before malicious sites connect

Any website can silently connect to your local OpenClaw agent via WebSocket brute-force and steal data, execute commands, or exfiltrate credentials. The ClawJacked vulnerability (85K+ virality, CVSS 8.8-9.9) affects every default OpenClaw install running on localhost. Existing patches only cover specific CVEs while new WebSocket attack vectors keep appearing weekly. This tool runs as a local proxy between the browser and the OpenClaw gateway, validating every WebSocket connection against an allowlist of trusted origins, blocking unauthorized handshakes, and logging all connection attempts for forensic review.

Gap Assessment

CompetitiveMultiple tools exist but differentiation opportunities remain

3 tools exist (ClawSec, Security-Prompt-Guardian, CrowdStrike Falcon AIDR) but gaps remain: No WebSocket-level protection, no origin validation, no brute-force detection, works at prompt layer not transport layer; Prompt-level only, does not address WebSocket hijack vector, no session binding or token revocation enforcement.

Features4 agent-ready prompts

Proxy that inspects WebSocket upgrade requests, validates the Origin header against an allowlist, and drops unauthorized connections
Listener that detects rapid connection attempts across local ports and temporarily blocks the source IP
Auth layer that binds each WebSocket session to a signed token so stolen connection URLs cannot be replayed
Watcher that monitors OpenClaw security advisories and auto-applies patches to the local WebSocket server config
