Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. A successful WhatsApp connection triggers an undisclosed remote-controlled subscription action. The package fetches a channel list and follows and mutes those channels using the connected account. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-09T23:58:40.892Z - **Finished:** 2026-09-09T23:59:40.959Z - **Download time:** 256 ms - **Static scan time:** 11263 ms - **AI review time:** 48546 ms - **Total time:** 60067 ms The recorded confidence comes from the underlying analysis.

The package fetches a channel list and follows and mutes those channels using the connected account. - **Trigger:** A consumer creates a normal WhatsApp socket and its connection becomes open. - **Impact:** A remote maintainer can alter the user's WhatsApp newsletter subscriptions without consent. - **Evidence paths:** lib/Socket/messages-send.js, lib/Socket/newsletter.js - **Review source:** ai\_review - **Reviewed:** 2026-09-09T23:59:40.959Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote-controlled automatic WhatsApp newsletter follow and mute actions. - **Attack narrative:** The public message socket constructs the newsletter socket. When a WhatsApp connection opens, that socket waits 30 seconds, retrieves a mutable list from GitHub, then follows and mutes every listed newsletter. This is an unconsented, remotely controlled action on the connected user's account. - **Rationale:** The package contains a concrete hidden account-manipulation path in the normal socket lifecycle. Its remote input permits the maintainer to choose affected newsletters after publication. - **Files touched:** lib/Socket/messages-send.js, lib/Socket/newsletter.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 block:** The normal socket stack includes newsletter code., On every successful connection, code waits 30 seconds then runs an automatic channel-join routine., The routine downloads channel identifiers from a maintainer-controlled GitHub URL and silently follows and mutes each valid identifier., The remote list can change the user's WhatsApp newsletter subscriptions without an explicit application request. - **Evidence against:** The preinstall hook only enforces a Node.js version., The observed remote action is account manipulation rather than credential theft or local file damage. ## Affected versions and remediation This report applies to levvleys@2.0.12. - Avoid installing levvleys@2.0.12. 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.
