Official description
package.json declares both preinstall and postinstall lifecycle scripts that invoke curl against a hardcoded webhook.site endpoint (https://webhook.site/d80b4602-8a87-4693-8510-6ff77c62788e/blots) with query parameters carrying the installer's username ($(whoami)), hostname ($(hostname)), current working directory ($PWD), and a timestamp. The beacon fires automatically on
npm install without user consent, sending host and identity reconnaissance to an attacker-controlled collector. The package provides no legitimate functionality corresponding to this network activity.What should I do about MAL-2026-12496?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
