Source: amazon-inspector (15e9740e7be22c3d68a1784e48d3e87414347b5e5697397ef0d8ab2295619962)

On npm install, the package runs a postinstall lifecycle script (node probe.cjs) that issues an HTTPS POST to a hardcoded webhook.site collector URL (https://webhook.site/a4bf0f9f-6d96-46e6-80ac-b76a5329f481) with the marker string CURSE_DEPENDENT_REMOTE_INSTALL_PROBE. The beacon fires unconditionally at install time with no configuration or opt-out, signaling to a third-party collector that the package resolved and executed inside the installer's environment. This is the canonical dependency-confusion / reconnaissance canary shape: the attacker learns that a given name resolves on the target's internal build infrastructure, enabling follow-on targeted attacks against environments where the name was expected to resolve privately.
