Summary
Malicious code in aliftech-ui (npm)
Details

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (e61479316af4cfc0884dfe88744a0ed14fa64e052471cc216667c80502689860)

postinstall.js runs automatically on npm install and reads os.hostname() and os.userInfo().username, then issues an https.get to a hardcoded webhook.site collector URL (https://webhook.site/539f8bb9-497a-4104-92f7-f95a77204cc2//), embedding the installer identifiers in the URL path. The package name mimics an organization prefix and is published at version 99.9.9, a shape consistent with dependency-confusion targeting of an internal package name; installing it causes any resolving build (including CI) to beacon identifying host and account data to an anonymous third-party collector.
