Carbonato Botnet Deploys AI Agents on Exposed Docker Hosts
The Carbonato botnet infects servers with unauthenticated Docker daemons on port 2375, installs the Hermes Agent AI framework, and uses Telegram to exfiltrate AI API keys. Defenders should audit Docker exposure, harden daemon security, monitor for Hermes Agent activity, and revoke compromised keys.
What Happened
ThreatDown researchers uncovered the Carbonato botnet, which targets Docker daemons exposed on port 2375 without authentication. The malware drops the open‑source Hermes Agent AI framework onto the host, then uses a Telegram bot to issue commands and exfiltrate stolen AI API keys.
Impact
Compromised hosts become command‑and‑control nodes that can spread to other reachable Docker services. The botnet harvests credentials for AI services, potentially enabling attackers to generate content, bypass rate limits, or incur charges.
What to Do
- Audit all Docker daemons for unauthenticated access on port 2375 and close the port or enable TLS authentication.
- Check for the Hermes Agent binary or related process names and remove any unauthorized instances.
- Block outbound traffic to Telegram’s API endpoints or enforce strict egress policies for container hosts.
- Revoke any AI API keys that may have been exfiltrated and rotate credentials.
- Apply the latest Docker security patches and follow Docker hardening guidelines.
