What is MAL-2026-16314?
MAL-2026-16314 is a malicious package in test1hh235, published on 21 Sep 2026.
Official description
Package declares both preinstall and postinstall lifecycle hooks that execute index.js on
npm install. index.js issues an HTTP GET to the hardcoded bare IP 128.199.122.145 over plain HTTP, embedding the package name in the query string (http://128.199.122.145/?test1hh235). Manifest shape is consistent with a dependency-confusion reconnaissance probe: version 99.99.99 (implausibly high to win resolution against an internal package), empty description, and a typo-prone name. The beacon fires automatically during install and signals successful resolution/installation to an attacker-controlled host, confirming the target environment for follow-on attack.What should I do about MAL-2026-16314?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
