What is MAL-2026-17156?
MAL-2026-17156 is a malicious package in aliftech-ui, published on 24 Sep 2026.
Official description
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/<hostname>/<username>), 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.
What should I do about MAL-2026-17156?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
