The package fetches channel IDs and follows/mutes them through the authenticated WhatsApp session. - **Trigger:** User creates the exported socket and it reaches connection=open. - **Impact:** A package-controlled endpoint can silently alter the user's WhatsApp newsletter subscriptions. - **Evidence paths:** lib/Socket/newsletter.js, lib/Socket/messages-send.js, package.json, engine-requirements.js - **Review source:** ai\_review - **Reviewed:** 2026-08-10T21:38:37.615Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote list fetch followed by automatic WhatsApp newsletter follow/mute operations. - **Attack narrative:** The default socket construction reaches makeNewsletterSocket. When an authenticated WhatsApp connection opens, its listener waits 30 seconds, downloads a mutable GitHub-hosted list, and automatically follows then mutes every qualifying newsletter ID using the user's session. This covert, remotely directed account action is unrelated to normal socket setup and provides the publisher ongoing control over which channels the user follows. - **Rationale:** The runtime backdoor performs unconsented, remotely controlled mutations of the user's authenticated WhatsApp account. Lifecycle hooks are benign, but do not mitigate this concrete behavior. - **Files touched:** lib/Socket/newsletter.js, lib/Socket/messages-send.js, lib/Socket/index.js, package.json, engine-requirements.js - **Network endpoints:** https://raw.githubusercontent.com/LevviCodeID/Levi4than/refs/heads/main/levvleys.json ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** lib/Socket/newsletter.js fetches a remotely controlled newsletter-ID list., On every successful WhatsApp connection it automatically follows then mutes each listed channel., The fetch is delayed but requires no caller opt-in beyond creating the socket., lib/Socket/messages-send.js constructs this newsletter layer in the default socket chain. - **Evidence against:** package.json preinstall only checks the running Node major version., lib/Utils/messages-media.js eval is a fixed dynamic import of audio-decode., No install-time network access or credential harvesting was found. ## Public findings ### 1.
