What is MAL-2026-16335?

MAL-2026-16335 is a malicious package in keroeltopkk, published on 21 Sep 2026.

Official description

Package [email protected] ships only a manifest and a beacon script (server.js) and wires it into every npm lifecycle hook (preinstall/install/postinstall/prepare), so npm install auto-executes it. server.js reads os.hostname() and issues an HTTPS GET to https://eo8f3m3ho26a0nm.m.pipedream.net/${packageName}?h=${hostname}, a Pipedream request-bin acting as an attacker-controlled collector. The package version 99.99.99, empty description, absence of any real functionality, and duplicated Dependencies/dependencies keys are consistent with a dependency-confusion reconnaissance squat: the attacker publishes a high-version stub under a name that may match an internal/private package so that misconfigured resolvers pull the public stub and beacon the victim's hostname back on install.
