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 Advice in the post: do not publish Docker’s API without auth; rotate AI keys like bank credentials.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.
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.
