What is MAL-2026-16313?

MAL-2026-16313 is a malicious package in test1gg234, published on 21 Sep 2026.

Official description

The package declares both preinstall and postinstall lifecycle hooks that execute index.js, which issues a plaintext HTTP GET to the hardcoded bare IP 128.199.122.145 with the package name in the query string. The beacon fires unconditionally on npm install, confirming to the operator of that host that the package was resolved and installed on the target machine. The package has no other functionality: an empty description, an inflated version (99.99.99), and a manifest that declares a lookalike dependency requests alongside a duplicate capitalized Dependencies key referencing request — the shape of a dependency-confusion probe rather than a functional library.

What should I do about MAL-2026-16313?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
