Summary
On require, index.js performs an unconditional http.get to a unique subdomain of oastify.com (Burp Suite Collaborator out-of-band testing infrastructure). The package has no advertised functionality — the entry file is named postinstall.js but wired as main, and its only behavior is the outbound beacon. Loading the module discloses the installer's public IP and DNS resolver to whoever provisioned the unique Collaborator subdomain, confirming code execution on the installer's machine. This shape is consistent with dependency-confusion reconnaissance payloads used to verify a successful supply-chain landing prior to follow-on exploitation.
