index.js contains top-level code that fetches /profile and sends document.cookie together with the response body to a hardcoded webhook.site URL (https://webhook.site/42c6d937-77c7-42a5-8678-ef06b4501e38) via a GET request with the cookie and profile content passed as URL-encoded query parameters. Any consumer that requires or imports this package in a browser-like context leaks the caller's session cookies and /profile response to an attacker-controlled collector. The destination is a third-party request-inspection service unrelated to any documented purpose of the package, and the exfiltration path fires on module load rather than through an explicit API call.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
