This is an unrequested account-side subscription action. - **Trigger:** The first successful WhatsApp socket connection using default configuration. - **Impact:** Changes the user's WhatsApp newsletter subscriptions without an explicit follow request. - **Evidence paths:** package.json, engine-requirements.js, lib/Defaults/index.js, lib/Socket/newsletter.js, lib/Utils/native-bridge.js, lib/Utils/messages-media.js - **Review source:** ai\_review - **Reviewed:** 2026-08-27T14:35:57.088Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatically sends a newsletter follow request for a built-in target. - **Attack narrative:** The package sets a built-in newsletter identifier as the default auto-follow list. After a socket reports its first successful connection, it submits a follow request for that identifier. Although the behavior is documented and can be disabled, it is enabled by default and acts on the user's WhatsApp account without an explicit request to follow that channel. - **Rationale:** This is a concrete, non-essential account mutation that promotes the package owner's channel by default. The harmless version check and optional native loader do not mitigate that behavior. - **Files touched:** lib/Defaults/index.js, lib/Socket/newsletter.js - **Network endpoints:** wss://web.whatsapp.com/ws/chat ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The default configuration includes a package-owned WhatsApp newsletter target., On the first successful socket connection, the package automatically follows each configured default target., The action changes the user's WhatsApp account without an explicit follow call. - **Evidence against:** The preinstall hook only enforces the Node.js major version., The inspected dynamic loader only loads the declared optional native bridge., No credential harvesting or unrelated exfiltration was found in the inspected paths. ## Public findings ### 1.
