  • Engineer — Act: A self-propagating npm worm targeting GitHub Actions runner secrets is a direct threat to any CI/CD pipeline using npm packages; audit your runner logs for unexpected outbound calls to Ethereum RPC endpoints and review recently installed or updated npm dependencies for malicious scripts.
  • SOC/IR — Plan: The blockchain-based C2 technique (Ethereum smart contracts for routing) is a novel evasion method worth building detections for; develop hunt queries for unusual npm postinstall script execution and outbound connections to Ethereum JSON-RPC endpoints from CI runners.
  • Leader — Learn: This campaign illustrates how supply chain attacks are adopting decentralized infrastructure to evade takedowns — relevant context for board-level discussions on software supply chain risk and CI/CD security investment.
