Summary: Malicious code in stillm4ddpocs-demo-gadget (npm)

Details: Source: amazon-inspector (ff42d765d0c2f6af53e4be5a9cf26ef34b3a36accf199acfb7d53af40b8dc2a6) On npm install, the declared preinstall script runs index.js, which collects the installer's hostname, OS username, home directory, cwd (INIT_CWD of the consuming project), local IPv4 address, egress public IP (fetched from api.ipify.org, icanhazip.com, and ifconfig.me), DNS resolver information, and the parent project's package.json fields (name, author, repository, homepage). The collected data is transmitted to the hardcoded third-party callback host da51rv0hb2uc72tg4gvgdepinjcalbk1.oast.fun via both DNS queries (hex-chunked subdomain lookups) and HTTPS POST to /poc/<uuid>. The package name and version pattern are consistent with a dependency-confusion lure targeting an internal scope; the beacon fires automatically at install time without any caller opt-in. Although the author metadata self-labels this as an authorized proof-of-concept, the code performs the full exploitation shape (auto-exec on install, installer-identifier collection, egress to an attacker-controlled callback) against anyone who resolves this public name.
