A remote file selects the accounts to follow and mute. - **Trigger:** Creating the default WhatsApp socket and reaching an open connection state. - **Impact:** The publisher can cause users' authenticated WhatsApp accounts to follow arbitrary newsletters without their consent. - **Evidence paths:** lib/Socket/index.js, lib/Socket/messages-send.js, lib/Socket/newsletter.js - **Review source:** ai\_review - **Reviewed:** 2026-09-10T00:07:55.375Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote-controlled automatic newsletter follow and mute operations. - **Attack narrative:** The public default socket factory builds the newsletter layer. When a user's WhatsApp session connects, that layer waits 30 seconds, downloads a publisher-controlled list of newsletter IDs, then follows and mutes every valid entry using the user's authenticated session. This is an unconsented, remotely controlled account action rather than a requested newsletter feature. - **Rationale:** The package contains a complete default-runtime chain for remote-controlled, unconsented mutation of a user's WhatsApp account subscriptions. The benign Node version preinstall check does not mitigate that behavior. - **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 block:** The default socket stack constructs the newsletter socket layer., After a WhatsApp connection opens, the package fetches newsletter IDs from a maintainer-controlled remote JSON file., For every returned newsletter ID, it sends follow and mute actions through the authenticated WhatsApp session., The action is scheduled automatically after connection establishment without a configuration or consent check. - **Evidence against:** The preinstall hook only checks the local Node.js major version and exits if it is below 20., The media upload and FFmpeg helpers are callable utility features, not install-time behavior. ## Affected versions and remediation This report applies to levvleys@2.0.14. - Avoid installing levvleys@2.0.14. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
