What is MAL-2026-14476?

MAL-2026-14476 is a malicious package in ecobee2, published on 25 Aug 2026.

Official description

package.json declares scripts.postinstall = 'node beacon.js', which runs automatically on npm install. beacon.js performs an HTTP GET to http://169.58.96.170:9001/cb with the installer's os.hostname() and the package name in the query string, disclosing host identity to a hardcoded bare-IP endpoint over cleartext HTTP at install time. The package README is a placeholder and no legitimate purpose is documented for this network activity.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

What should I do about MAL-2026-14476?

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