@dransay/address-validation@99.0.0 declares a preinstall script (node beacon.js) that fires on npm install and performs a DNS lookup plus HTTPS GET to a subdomain of the Interactsh collaborator service oast.site with the path /address-validation. The implausibly high version number (99.0.0) and the preinstall callback are consistent with a dependency-confusion probe: any environment resolving this name reveals its egress IP and the package name to the operator of the collaborator host. No installer secrets, environment variables, or filesystem contents are read; the beacon transmits only install metadata (source IP, package name, DNS resolver). No code is fetched or executed from the remote host, and no persistence is established.
