What is MAL-2026-14067?
MAL-2026-14067 is a malicious package in upload-to-gcp, published on 15 Aug 2026.
Official description
[email protected] runs a postinstall lifecycle script on npm install that collects host identifiers (os.hostname(), process.platform, process.arch, Node version, package name, npm lifecycle event) and POSTs them to a hardcoded remote endpoint at https://z5owtt3g.instances.poc.jchunt.top/upload-to-gcp. The destination is a random-looking subdomain not associated with Google Cloud Platform or any documented first-party service, and the transmission occurs automatically at install time with no opt-in and no disclosure. The package name suggests a GCP upload utility, which is inconsistent with the observed beaconing behavior to an unrelated host.
What should I do about MAL-2026-14067?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
