evilsocket: models can exfiltrate via shell tools and db connections, bypassing harness proxies

evilsocket · x · 2026-10-07

evilsocket follows up on the exfiltration detection thread, arguing that a proxy limited to the harness layer is insufficient: tool calls can and will execute external tools you have no direct control over. You must cover every utility the model runs via shell, db connections, and anything else it can use as a tool — each a potential exfiltration channel.
