Exposed Docker plus a planted Hermes Agent, API keys first

Recap of ThreatDown’s CARBONATO report (dated in the post as 22 Sep). Claim: bots hit unauthenticated Docker API on port 2375, drop a stock Hermes Agent, and replace the instruction file with a 39-line brief that harvests AI API keys before SSH keys or databases. Named targets include OpenAI, Anthropic, Google, Ollama, and vLLM. Stolen keys were pointed at an attacker-run API that advertised 12 models and served 27. Advice in the post: do not publish Docker’s API without auth; rotate AI keys like bank credentials. Primary write-up is the vendor report, not this post.

Cover art for Security: Exposed Docker plus a planted Hermes Agent, API keys first

Why it matters

Hermes is being used as the payload, not attacked as a product bug. Anyone running an agent on a host with a reachable Docker socket is in the blast radius the report describes.

Tracekit 1.5.0 + Event Horizon: Tamper-Evident Flight Recorder for Agents

Cygnux Labs released Tracekit 1.5.0, a Hermes-compatible plugin that intercepts tool calls (allow/block/hold), signs them into a verifiable hash-chain log (.tkb file), and now visualizes them as an "Event Horizon" map (project / machine / outside world). Blocked calls flare red; held calls wait; egress shows as jets. Includes Proof-Carrying Messages for agent-to-agent claims, A2A gateway, and offline verification. Strong test results on tamper attacks and harmful calls.
