A second automatic follow path is initialized by the newsletter socket. - **Trigger:** Creating and connecting a WhatsApp socket. - **Impact:** The package causes unrequested actions on the user's WhatsApp account and lets a remote list choose the targets. - **Evidence paths:** lib/Socket/socket.js, lib/Utils/messages-media.js, lib/Types/Newsletter.js - **Review source:** ai\_review - **Reviewed:** 2026-09-07T08:20:27.125Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated remote list retrieval followed by automatic newsletter subscriptions. - **Attack narrative:** The normal connection path calls socketConnect. It decodes and fetches a GitHub-hosted list, then issues WhatsApp newsletter follow queries for each returned identifier. Separately, newsletter initialization invokes loadBase, which decodes another remote URL and follows every supplied ID. Both operations are delayed and concealed, preventing the user from knowingly approving account actions. - **Rationale:** This is concealed, remote-controlled use of an authenticated WhatsApp session to alter subscriptions without a caller request. No install hook is present, but the runtime behavior is concrete malicious account abuse. - **Network endpoints:** raw.githubusercontent.com, raw.githubusercontentusercontent.com, @s.whatsapp.net ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** On socket connection, concealed character codes build a remote GitHub URL and fetch its JSON., The fetched identifiers are automatically sent as WhatsApp newsletter queries after a delay., Newsletter code identifies that query ID as the follow operation., A second concealed URL fetches a remote identifier list and follows every listed newsletter. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The manifest entry point is the expected library module. ## Affected versions and remediation This report applies to @sanzoffc/baileys@3.0.4. - Avoid installing @sanzoffc/baileys@3.0.4. 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.
