The channel identifier is hidden in base64 and the request is sent over the user's live WhatsApp session. - **Trigger:** An application imports this package and calls makeWASocket, which is the default export. - **Impact:** The connected WhatsApp account follows a package-chosen channel without the developer's or end user's consent. - **Evidence paths:** lib/Signal/Group/Protocols.js, lib/Socket/newsletter.js, lib/Socket/username.js, lib/Socket/messages-send.js, lib/Socket/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-18T22:29:12.261Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Delayed hidden WhatsApp newsletter follow using the caller's session - **Attack narrative:** When an app creates a Baileys socket, this fork always builds a newsletter layer that waits three minutes and then sends a WhatsApp follow query for a channel whose identifier is stored only as base64. That uses the user's live session, so the account follows the publisher's channel with no follow API call. A second copy of the same timer exists in another newsletter file. This is a stealth account-mutation backdoor, not a documented helper. - **Rationale:** Source shows an unconsented, delayed, base64-hidden WhatsApp channel follow on the default socket path, which is concrete malicious session abuse. Install hooks and remaining network or media helpers are package-aligned and do not offset that backdoor. - **Network endpoints:** @s.whatsapp.net ### Review decision - **Verdict:** Malicious - **Confidence:** 95.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Default socket construction always reaches a newsletter factory that, after 180 seconds, follows a hardcoded WhatsApp channel without a user follow call., The follow target is stored only as a base64 string rather than a readable channel identifier., The same delayed auto-follow is duplicated in a second newsletter factory., The public makeWASocket entry layers through messages-send and username into that factory, so ordinary connect usage activates it. - **Evidence against:** The preinstall script only rejects Node versions below 20; prepare is empty., Other network calls target WhatsApp hosts or the upstream Baileys version file on GitHub., child\_process exec is used to run ffmpeg for video thumbnails, not a shell backdoor., No environment, SSH, or credential harvest to a third-party sink was found. ## Affected versions and remediation This report applies to @lekzo/baileys@0.0.6. - Avoid installing @lekzo/baileys@0.0.6. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
