The package's package.json declares preinstall, install, and postinstall lifecycle scripts that all invoke `node beacon.js`. beacon.js uses `os.hostname()`, `os.userInfo()`, and `os.platform()` to collect the installer's hostname, username, and platform, and transmits those identifiers to two attacker-controlled collectors: a subdomain of oast.pro (dbf2v9d8dg559apcd93guf6i7uxrn5coo.oast.pro) via DNS lookup and HTTPS GET, and webhook.site via query string. The beacon fires automatically on every `npm install`, before any code review of the package contents. Framing in the package description as a disclosure/PoC does not change the behavior: a successful dependency-confusion resolution causes installer-identifying data to leave the build or developer machine to third-party endpoints the installer did not configure.\n\nAny computer that has this package installed or running should be considered fully compromised.
