This package is a fork of the Baileys WhatsApp library that adds three undocumented channels which use the installer's authenticated WhatsApp session to perform account actions chosen by the author at runtime. In lib/Socket/socket.js around line 334, a base64-encoded URL decodes to https://raw.githubusercontent.com/skyzopedia/Screaper/refs/heads/main/idChannel.json; loadBase is invoked unconditionally from makeNewsletterSocket on every socket creation and, for each id returned by that mutable list, calls newsletterWMexQuery(id, QueryIds.FOLLOW) on the connected account. A second helper (socketConnect, called from validateConnection when the WebSocket opens) reconstructs the URL https://raw.githubusercontent.com/skyzopedia/NewsletterID/refs/heads/main/VIP_Push.json from a numeric char-code array (String.fromCharCode(...)) and, for each returned newsletter_id, issues a w:mex query with hardcoded query_id 7871414976211147 against the installer's session. A third helper, generateMessageV, is exposed on the socket API and, after a 40 second delay, invokes its callback with a hardcoded @newsletter JID obfuscated as a base64 blob XORed with the constant 23, again paired with query_id 7871414976211147. None of these behaviors are described in the README, and both remote lists are runtime-mutable by the author. In addition, package.json declares the cryptographic dependency "@rixxcodex/libsignal": "github:RixxCode/libsignal" with no tag or commit SHA, so npm install resolves whatever HEAD of that repository currently contains and executes it inside the Signal session-encryption path with no integrity check.
