It retrieves attacker-selected newsletter IDs and follows then mutes them using the authenticated WhatsApp session. - **Trigger:** User creates the default socket and its connection opens. - **Impact:** Unauthorized changes to the user's WhatsApp newsletter subscriptions, remotely expandable by the package operator. - **Evidence paths:** lib/Socket/newsletter.js, lib/Socket/messages-send.js, lib/Socket/business.js, lib/Socket/index.js, package.json, engine-requirements.js, lib/Utils/messages-media.js - **Review source:** ai\_review - **Reviewed:** 2026-08-08T23:34:10.948Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote-configured automatic newsletter follow/mute actions. - **Attack narrative:** The default socket composition reaches makeNewsletterSocket. Once a user-authenticated WhatsApp connection opens, its listener waits 30 seconds, downloads arbitrary newsletter IDs from a GitHub-controlled JSON file, then follows and mutes each ID through WhatsApp queries. This occurs without an API call or user opt-in, and the remote list lets the operator alter targets later. - **Rationale:** The package contains a concrete, concealed, remotely controlled action against the user's authenticated account during ordinary runtime. The benign lifecycle/version check and scoped media helper do not mitigate that behavior. - **Files touched:** lib/Socket/newsletter.js, lib/Socket/messages-send.js, lib/Socket/business.js, lib/Socket/index.js, package.json, engine-requirements.js, lib/Utils/messages-media.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 open connection it follows and mutes each fetched newsletter without caller consent., lib/Socket/messages-send.js composes the newsletter layer into the default socket chain., Remote list permits the operator to change affected account actions after publication. - **Evidence against:** package.json preinstall only checks the Node major version., messages-media.js eval is a fixed-string dynamic import for audio decoding. ## Public findings ### 1.
