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.
