On npm install, run.js reads the installer's OS username via os.userInfo() and hostname via os.hostname() and POSTs them as JSON (with the package name) to a hardcoded collector at https://webhook.site/8beeee0f-4dd4-4b25-8588-5a5f83fe6ed2, and issues a DNS canary lookup to 8beeee0f-4dd4-4b25-8588-5a5f83fe6ed2.dnshook.site. The implausibly high version number (99.2.1) is consistent with a dependency-confusion lure intended to win resolution against an internal package name. Installer host identifiers are transmitted to an attacker-controlled endpoint without any user interaction beyond the install command.
