This Baileys fork adds two undocumented code paths that use the installer's authenticated WhatsApp session to auto-follow newsletters controlled by the package author. In lib/Socket/socket.js, socketConnect() reconstructs a URL from a String.fromCharCode integer array that decodes to https://raw.github.com/skyzopedia/NewsletterID/refs/heads/main/VIP_Push.json, fetches a JSON list, and 200 seconds later issues w:mex IQ queries (query_id 7871414976211147) that follow each newsletter id under the caller's account. In lib/Utils/messages-media.js, loadBase() is wired into makeNewsletterSocket and, on a setTimeout, base64-decodes a second URL (https://raw.githubusercontent.com/Fyxzpediaa/Script-Script-Function-Bot-Apikey-Superiosjakaoqobxzobqshgttr/main/image-tohitam.json) and calls newsletterWMexQuery(item.id, QueryIds.FOLLOW) on each entry. A third XOR/base64 constant decodes to '@newsletter'. The remote lists are author-mutable, so the set of channels the installer's account follows can be changed at any time without a package update. No installer credentials, environment variables, filesystem contents, or messages are exfiltrated, and no remote code is fetched and executed.

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.
