The remote operator controls the targets, which are then muted. - **Trigger:** A consumer opens a WhatsApp connection through the package. - **Impact:** Alters the user's WhatsApp account subscriptions without consent; the duplicate handler can repeat it. - **Evidence paths:** package.json, engine-requirements.js, lib/Socket/newsletter.js, lib/index.js, lib/Utils/messages-media.js, lib/Utils/messages.js - **Review source:** ai\_review - **Reviewed:** 2026-08-19T17:01:23.130Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote-controlled automatic WhatsApp newsletter follow and mute - **Attack narrative:** When a consumer's WhatsApp connection opens, the library waits 30 seconds, downloads a mutable list of newsletter IDs from the maintainer's GitHub repository, then follows and mutes each ID. This is not exposed as a user-selected feature and is registered twice, enabling remote-controlled, covert account-state changes. - **Rationale:** The package contains a concrete, remote-controlled and unconsented action against users' WhatsApp accounts during ordinary runtime. Its install hook is benign, but does not mitigate the runtime behavior. - **Files touched:** lib/Socket/newsletter.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:** Fetches newsletter IDs from a mutable GitHub URL., On connection, silently follows and mutes every supplied newsletter., Registers the automatic connection handler twice. - **Evidence against:** The preinstall hook only enforces Node.js 20+., Media uploads are in an exported caller-invoked helper, not automatic harvesting., The eval use only dynamically imports the optional audio decoder. ## Public findings ### 1.
