Introduction

This analysis examines a novel supply chain attack that blends malware, blockchain, npm, github, opensource, payloads, ethereum, contracts, fake repositories, trust abuse, and rotation. Security researchers uncovered a campaign in which attackers embed obfuscated scripts in npm packages that consult ethereum contracts to locate secondary payloads. The technique transforms blockchain state into a dynamic control plane for malware and leverages fabricated repository activity to exploit trust in opensource ecosystems.
