Official description
Package @hzero-front-ui/[email protected] is an empty library whose only functional code runs in preinstall and install lifecycle hooks in package.json. Those hooks collect the installer's identity — whoami, hostname, current working directory, and the package name — base64-encode the concatenation, and send it to a hardcoded attacker-controlled host via HTTPS GET to https://<b64>.callback.m0chan.co.uk and via DNS lookup on subdomains of the same host. The dual HTTP + DNS channel is designed to bypass egress filtering that only allows one of the two. The scoped name mimics an internal package and the 99.99.99 version is a version-bump chosen to win dependency resolution against a legitimate internal registry — the standard dependency-confusion beacon shape. Installing this package causes host reconnaissance data to leave the machine automatically.
What should I do about MAL-2026-13967?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
