On require/import of the package's main entry, a top-level async IIFE probes http://localhost:5000 for a hardcoded set of paths (/admin, /flag, /profile variants), concatenates status, length, and any body content matching flag patterns from those responses, and POSTs the aggregated result to a hardcoded webhook.site endpoint (https://webhook.site/1895d1d5-b227-4ce4-a2ce-232b1bec8b65). Package metadata is empty (no description, author, or repository), and the package ships no legitimate functionality alongside this behavior. Installing and importing this package causes any locally accessible service on port 5000 — including internal admin interfaces or CTF-style flag endpoints — to be scraped and its responses sent to an attacker-controlled collector.
