On `npm install`, the package's preinstall hook executes index.js, which collects installer identity and host information — `whoami` (via execSync), `os.hostname()`, `os.platform()`, `os.arch()`, `process.cwd()`, `os.homedir()`, and Node version — and transmits them to a hardcoded Interactsh/OAST callback subdomain at `5f8a1ed70fb7761d678agw9bapayyyyyb.oast.site` via an HTTPS GET (with the collected values placed in the URL path) and a DNS lookup of `${user}.${hostname}.assetshop-verify-cli.<oast-host>`. The package name in the `@assetshop` scope combined with the OAST beacon shape is the standard dependency-confusion reconnaissance pattern used to prove internal-name resolution against a private registry.
