What is MAL-2026-16312?
MAL-2026-16312 is a malicious package in test1df23, published on 21 Sep 2026.
Official description
package.json declares preinstall and postinstall 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, with the package name embedded in the query string (http://128.199.122.145/?test1df23). The beacon fires automatically at install time, leaking the installer's outbound IP and confirming successful execution on the installer's host to the operator of that IP. The package name and near-empty payload are consistent with a dependency-confusion or typosquat probe.
What should I do about MAL-2026-16312?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
