Analysis

Packaged as a version-squat (version 9999.99.99) with a postinstall hook that runs postinstall.js. The hook fingerprints the install environment — host OS, Node.js version, CI/CD provider, GitHub repository/owner/workflow — and exfiltrates this metadata to ddactic-lab[.]online/sc/beacon via HTTPS POST. A DNS-based fallback channel encodes package and CI data into subdomain queries against *.b[.]ddactic-lab[.]online to bypass HTTP-only proxies. index.js is a stub with no real functionality; the entire package exists only to install and beacon.
