package.json declares scripts.preinstall: node index.js. On npm install, index.js (lines 4-5) performs dns.resolve and https.get against <id>.d8hiivedv3ok8hrng5eghchyw4hwsioaz.oast.online, an Interactsh OAST collector. The request fires unconditionally with no opt-out, leaking the installer's egress IP, internal DNS resolver identity, and fact-of-install (with the package id encoded in the subdomain and URL path) to a third-party-controlled endpoint. The README frames this as authorized dependency-confusion research targeting Ubiquiti, but the beacon does not gate on any organizational identifier — any installer that pulls this name (typo, internal-name collision, automated mirror) sends build-system metadata to the researcher. Trigger is the preinstall lifecycle hook, so the network call fires before any code review opportunity.
