"Shai-Hulud" Worm Compromises npm Ecosystem in Supply Chain Attack (Updated November 26)

A self-replicating worm named 'Shai-Hulud' has compromised hundreds of software packages in a supply chain attack specifically targeting the npm ecosystem. This represents a significant threat to the JavaScript/Node.js development community as npm is one of the largest package repositories. The worm's self-replicating nature allows it to spread automatically across the ecosystem, potentially affecting countless downstream applications and developers. The attack demonstrates the vulnerability of open-source package managers to malicious actors. Given the scale of compromise involving hundreds of packages, this poses a critical risk to software supply chain security.
