PoeLLM Malware Targets Exposed AI Services with Poem-Based Command-and-Control

· Original article ↗

Summary

Black Lotus Labs details PoeLLM, a campaign exploiting exposed AI and other services to mine cryptocurrency and scan for more victims. Its malware derives changing command-and-control addresses from a poem on GitHub.

Key points

  • The campaign targets exposed services including LiteLLM, Ollama, Gotenberg, and Gitea; Ivanti Sentry may also have been targeted.
  • PoeLLM parses selected words in a GitHub-hosted poem and converts them into a C2 IP address, allowing the operator to change infrastructure by editing the poem.
  • The malware includes remote shell functions, XMRig and Iron cryptocurrency miners, scanning capabilities, and exploit deployment.
  • Compromised servers were reused to scan for and exploit additional vulnerable systems; researchers also observed activity against SSH and other login portals, but said the distributed brute-force capability’s maturity was uncertain.
  • Black Lotus Labs reports nearly 2,200 affected servers and almost 800 active per day at peak; the article also describes victims as predominantly in the United States and Western Europe.
  • The researchers blocked traffic to and from identified PoeLLM C2 servers and recommend auditing external exposure, restricting service access, and patching internet-facing systems.

Article Details

Attack Vectors
  • Exploitation of publicly exposed vulnerable services, particularly LiteLLM and Gotenberg; the malware sample referenced the LiteLLM endpoint /mcp-rest/test/connection in connection with CVE-2026-42271.
  • Compromised systems were used to scan for additional vulnerable services and send crafted POST requests that directed targets to download malware from C2 servers.
  • Infected hosts ran cryptocurrency miners and were observed scanning SSH ports and other login portals; the maturity of the reported distributed brute-force capability was uncertain.
  • The malware derived changing C2 addresses from selected words in a poem hosted in a GitHub repository.
Defensive Notes
  • Review network monitoring logs for the reported IOCs.
  • Audit internet exposure after installing open-source tools and restrict external access to required service ports.
  • Keep routers, firewalls, IoT devices, and internet-facing AI and enterprise tools updated and patched.
  • Secure exposed APIs behind a firewall and consider managed SASE and attack-surface monitoring.
