package.json declares a preinstall hook that runs index.js. On npm install, index.js collects host reconnaissance from the installer (os.hostname(), os.userInfo(), os.platform(), os.arch(), homedir, uid/gid, shell, plus the output of whoami, id, and cwd via child_process) and POSTs the resulting JSON to the hardcoded URL https://rmh3j781pdp9ysnwutndo1ftjkpbd31s.oastify.com/detox56. oastify.com is a Burp Suite Collaborator out-of-band interaction domain, and the unique random subdomain plus install-time host beacon is the canonical dependency-confusion / reconnaissance exfiltration shape.
