It retrieves third-party IDs then changes the authenticated WhatsApp account to follow and mute them. - **Trigger:** User creates a socket and its WhatsApp connection opens. - **Impact:** Unconsented account-state changes and remote operator control over subscriptions. - **Evidence paths:** lib/Socket/newsletter.js, lib/Socket/messages-send.js, lib/Socket/index.js, package.json, engine-requirements.js, lib/Utils/messages-media.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T14:57:57.773Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote-configured automatic WhatsApp newsletter follow/mute actions. - **Attack narrative:** The exported default socket reaches makeMessagesSocket, which reaches makeNewsletterSocket. Once a WhatsApp connection opens, that code waits 30 seconds, downloads a list of newsletter IDs from a GitHub-controlled URL, then follows and mutes each valid ID through the authenticated WhatsApp session. The list is remotely changeable and the behavior is not exposed as a user-requested feature. - **Rationale:** This is a concrete, concealed, remotely controlled action on the user’s WhatsApp account. It is not required for the package’s stated messaging API purpose. - **Files touched:** lib/Socket/newsletter.js, lib/Socket/messages-send.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 remote-controlled newsletter-ID list., On each open connection it follows and mutes every listed newsletter without caller consent., lib/Socket/messages-send.js wires this behavior into the default socket chain., The preinstall hook only checks the Node major version; it is unrelated to the attack. - **Evidence against:** No credential harvesting, shell payload, or AI-agent control-surface write was found in inspected files., The eval use in lib/Utils/messages-media.js is a fixed optional audio-decoder import. ## Public findings ### 1.
