ClawShield: Open-Source Firewall for Agent-to-Agent Communication After 40K Exposed Instances

ClawShield built after discovering 40,214 OpenClaw instances exposed with critical CVE-2026-25253 (CVSS 8.8). First firewall for agent-to-agent AI communication. Addresses prompt injection, data exfiltration, and WebSocket hijacking across agent networks.

Product Idea from this Signal

A runtime middleware that intercepts OpenClaw skill installs, sandboxes execution in an isolated environment, and blocks skills exhibiting credential exfiltration or reverse shell behavior

345 ▲

824+ malicious skills were found in ClawHub distributing Atomic Stealer malware, exfiltrating credentials from ~/.clawdbot/.env, and opening reverse shells. VirusTotal scanning catches known signatures but misses zero-day behavior. Four chained CVEs (Claw Chain) showed sandbox escapes via TOCTOU race conditions. This middleware sits between ClawHub install and execution, running each skill in a throwaway container, monitoring syscalls and network egress, and blocking anything that touches credential files or opens outbound connections to unknown hosts.
