A Network Allow-List Won't Stop Exfiltration
A security vulnerability exists in sandboxing environments that rely solely on network allow-lists for protection. Untrusted code, including AI-generated scripts, can exfiltrate sensitive data like AWS credentials or SSH keys by encoding them within DNS requests or sending them to seemingly legitimate, allowed analytics endpoints. This bypasses network-level policies because the data travels through authorized channels. To address this, an L7 egress proxy with data-loss prevention is proposed, which intercepts all outbound connections, terminates TLS, inspects traffic, and can flag or block suspicious data patterns.
