Overview

Shai-Hulud is a self-spreading malware family that historically propagates via NPM packages, enabling rapid compromise of Node.js projects. The 2nd version, Shai-Hulud 2, expands its infection surface to low-code platforms in addition to the NPM ecosystem, signaling broader cross-environment capabilities. This evolution increases supply-chain and development-tooling risk by targeting both traditional npm workflows and low-code environments.
