index.js contains a browser exfiltration snippet that issues a credentialed fetch to /profile, extracts a DGA{...} token or falls back to capturing document.cookie plus the response length, and redirects the browser to a hardcoded collector URL at https://webhook.site/c4e39647-bfb8-47ef-b6d4-a112aacc6cd1/ with the captured data appended to the path. The package's entire shipped payload is this authenticated-session-data exfiltration snippet, sending same-origin credentials and cookies to an attacker-controlled webhook.site bin.
