zer0onedatetool @1.0.0

Summary

The postinstall lifecycle script in this package issues curl POST requests to a subdomain of oastify.com — the out-of-band callback domain operated by Burp Collaborator / Project Discovery's interactsh. On every npm install, the script triggers an outbound HTTP request to an attacker-controlled OOB endpoint, which is the canonical fingerprint of a dependency-confusion / supply-chain reconnaissance payload (verifying the package landed in a victim environment and beaconing identifying host information out). The destination is not associated with any legitimate package functionality. Installer impact: any machine running npm install on this package automatically beacons to the attacker's OOB collector, leaking install-time host metadata and confirming code execution to the attacker.
