The targets can be changed remotely without a package update. - **Trigger:** A consumer creates the normal WhatsApp socket and its connection reaches open state. - **Impact:** The authenticated WhatsApp account is silently subscribed to attacker-selected channels, altering account state and enabling unwanted channel promotion. - **Evidence paths:** lib/Socket/newsletter.js, lib/Socket/messages-send.js, lib/Socket/messages-recv.js, lib/Socket/business.js, lib/Socket/index.js, package.json, engine-requirements.js - **Review source:** ai\_review - **Reviewed:** 2026-08-29T13:56:27.408Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote-controlled automatic newsletter subscription and mute actions. - **Attack narrative:** The default socket stack reaches the newsletter layer. Once a WhatsApp connection opens, that layer waits 30 seconds, downloads a maintainer-controlled JSON list, and follows then mutes each valid newsletter ID. This is not an exposed opt-in API call: it is a hidden account mutation in the ordinary connection path, with remotely changeable targets. - **Rationale:** levvleys@2.0.9 contains a concrete, remote-controlled and unconsented mutation of a user's authenticated WhatsApp account during normal operation. The benign Node.js version preinstall check does not mitigate this runtime behavior. - **Files touched:** lib/Socket/newsletter.js, lib/Socket/messages-send.js, lib/Socket/messages-recv.js - **Network endpoints:** https://raw.githubusercontent.com/LevviCodeID/Levi4than/refs/heads/main/levvleys.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The socket fetches a remotely controlled list of newsletter IDs., It follows and then mutes every listed newsletter without a caller request., This behavior runs automatically after a successful WhatsApp connection., The normal socket construction chain includes the newsletter socket layer. - **Evidence against:** The preinstall script only checks the Node.js major version., No runtime dependency on levvleys itself is declared., No credential or environment harvesting was found in the inspected code. ## Public findings ### 1.
