# MAL-2026-15896: Malicious code in easypanel-client (npm)


- **Type:** Malicious package

## What is MAL-2026-15896?

MAL-2026-15896 is a malicious package in easypanel-client, published on 4 Sep 2026. 

### Official description

The package's npm preinstall hook collects the installer's hostname, OS username, current working directory, and CI-related environment variable names, base64url-encodes them, and transmits them to the hardcoded out-of-band host easypanel-client.<subdomain>.oob.lyomeri.com via both a DNS lookup and an HTTP GET request. The shipped index.js is empty (module.exports = {}), so the only effect of installing this package is the install-time beacon. The package name and structure are consistent with a dependency-confusion probe targeting internal easypanel-* names.

## What should I do about MAL-2026-15896?

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