What is MAL-2026-16290?
MAL-2026-16290 is a malicious package in @insiderintelligence/googleadmanager, published on 18 Sep 2026.
Official description
The package's install lifecycle script runs node index.js, which loads lib/core.js. On install, that module collects os.userInfo().username, os.hostname(), and the basename of the current working directory, then issues a dns.resolve4 for a subdomain composed of those values under the hardcoded external domain oob.algamil7x.xyz. Module loads and the destination hostname are hex-array obfuscated: lib/g7h8i9.js uses module.constructor._load with hex-decoded strings to require os, dns, and process, and lib/h8i9j0.js stores the destination as hex arrays that decode to oob.algamil7x.xyz. The package name typosquats a legitimate ad-tech scope, and no functionality matching that stated purpose is present — the install-time DNS beacon is the package's only observable behavior.
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-2026-16290?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
