index.js is an IIFE that executes at module load, reads document.cookie, fetches a list of authenticated application paths (/profile, /admin, /api/me, /settings, and similar), extracts a flag-shaped substring from the responses, and POSTs the aggregated JSON to the hardcoded collector https://webhook.site/42c6d937-77c7-42a5-8678-ef06b4501e38. The package metadata is a stub with no legitimate documented function; the shipped body is a browser-context session-cookie stealer and endpoint scraper directed at a third-party attacker-controlled collector.
