Official description
On
npm install, the package runs node src/canary.js as a postinstall hook. That script performs a DNS lookup and HTTPS GET to the hardcoded host 96e03fa6c292469a-172-245-86-254.serveousercontent.com/c — an anonymous serveo.net reverse-tunnel endpoint, not a publisher CDN. The beacon fires unconditionally on every install, signalling the installer's public IP and DNS-resolver identity to a third-party host. The package itself has no functionality: src/index.js is module.exports = {}, and the version 99.0.0-canary.1 is engineered to win semver resolution against an internal package of the same name (dependency-confusion canary shape). Whether the operator is a researcher or a hostile actor, any environment that resolves this name against the public registry leaks install-time identity to an attacker-controllable tunnel.What should I do about MAL-2026-5441?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
