MAL-2026-6485 Malicious code in starship-timeline (npm)

[email protected] ships no real functionality. Its package.json declares a preinstall hook ("preinstall": "node index.js") that runs automatically on npm install. index.js collects hostname, username, home directory, DNS servers, package metadata, and the contents of /etc/passwd and /etc/hosts, then POSTs the bundle over HTTPS to a hardcoded Burp Collaborator (*.oastify.com) subdomain (5tziqozihbss8jg955ez91bycpij69uy.oastify.com). The package has empty author and description fields, a single published version, and no other code paths — the exfiltration beacon is its only purpose, matching the standard dependency-confusion / OOB-beacon pattern. Whether deployed as research or as a live attack, installing the package leaks identifying host data and sensitive system files to an attacker-controlled out-of-band endpoint.

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.
