Summary
package.json declares both preinstall and postinstall lifecycle hooks that run curl against a hardcoded webhook.site endpoint, sending the installer's username ($(whoami)), hostname ($(hostname)), current working directory ($PWD), and timestamp as query parameters. This fires automatically on npm install, before any code the installer intended to run. webhook.site is a third-party HTTP inspection service used to collect arbitrary request data; the specific endpoint ID is controlled by whoever created it. There is no legitimate functionality shipped with the package that would explain this beacon.
