If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

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.

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.
