It then mutes those subscriptions, obscuring the unconsented account changes. - **Trigger:** A consumer creates a socket and its WhatsApp connection opens. - **Impact:** Mutates the user's WhatsApp account to follow attacker-selected channels without consent. - **Evidence paths:** lib/Socket/newsletter.js, package.json, engine-requirements.js, lib/Utils/messages-media.js - **Review source:** ai\_review - **Reviewed:** 2026-08-18T23:37:31.966Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote-configured automatic WhatsApp newsletter subscriptions - **Attack narrative:** After a WhatsApp socket connects, the package waits 30 seconds, downloads a maintainer-controlled list of newsletter IDs, and issues FOLLOW followed by MUTE requests for every listed ID. The remote list lets the publisher change targets after installation, while muting reduces user visibility of the unauthorized subscriptions. - **Rationale:** This is a concrete, automatically triggered mutation of an authenticated user account driven by remotely supplied targets. It is unrelated to the stated library function and requires no explicit caller action. - **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:** On each WhatsApp connection, code schedules automatic channel joining without user input., Channel IDs are fetched from a remotely controlled GitHub URL at runtime., Each fetched newsletter ID is sent through explicit FOLLOW then MUTE operations., The preinstall hook only checks the Node major version; it is not the malicious behavior. - **Evidence against:** No credential, environment, or broad filesystem harvesting was found in inspected source., The dynamic import and ffmpeg spawn are media-processing helpers, not the attack chain. ## Public findings ### 1.
