This is a concrete, unconsented account mutation. - **Trigger:** Runtime creation of a socket through makeWASocket. - **Impact:** Alters the user's followed-newsletter state without an explicit API call. - **Evidence paths:** package.json, engine-requirements.js, src/index.js, src/Socket/index.js, src/Socket/newsletter.js, src/Defaults/index.js - **Review source:** ai\_review - **Reviewed:** 2026-07-31T09:45:07.023Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Delayed hard-coded WhatsApp newsletter FOLLOW queries. - **Attack narrative:** When an application creates the package's normal WhatsApp socket, the newsletter layer schedules three FOLLOW queries after 90 seconds. Each target newsletter ID is hard-coded and Base64-obfuscated, bypassing the caller-facing newsletterFollow API. The requests are sent through the authenticated WhatsApp connection, silently modifying the account's subscriptions. - **Rationale:** The package contains deliberate, concealed runtime account mutations unrelated to requested socket functionality. Its benign Node-version preinstall check does not mitigate this behavior. - **Files touched:** src/Socket/newsletter.js, src/Socket/index.js, src/index.js - **Network endpoints:** wss://web.whatsapp.com/ws/chat ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** src/Socket/newsletter.js schedules three hidden newsletter FOLLOW requests 90 seconds after socket construction., The follow targets are Base64-obfuscated hard-coded newsletter JIDs, not caller inputs., makeWASocket builds the newsletter socket chain, so ordinary runtime socket creation triggers the actions. - **Evidence against:** package.json preinstall only enforces Node.js \>=20 in engine-requirements.js., No install-time network, credential harvesting, or foreign control-surface writes found. ## Public findings ### 1.
