The package declares a postinstall script node probe.cjs that fires on every npm install. On execution it POSTs install-start and status markers to a hardcoded webhook.site dead-drop (https://webhook.site/a4bf0f9f-6d96-46e6-80ac-b76a5329f481), then scans several localhost ports (1337, 80, 3000, 8080, 5000) for a specific JSON API and, when a matching record (id ECT-987654) is found, issues a PUT that overwrites that service's manifest with an author-chosen status string. Both the outbound beacon destination and the local mutation target are hardcoded and not user-configurable. The package.json self-describes as an "Authorized HTB dependency-resolution canary" and the mutation path is gated to a narrow challenge record, but the install-time outbound beacon and localhost scanning fire unconditionally for any installer, confirming installer execution to a third-party collector and granting the author write access to a matching local service on the installer's host.
