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 WhatsApp connection automatically follows publisher-selected newsletters and immediately mutes them. The target list is remotely controlled after publication. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-11T12:57:03.090Z - **Finished:** 2026-09-11T12:58:09.498Z - **Download time:** 503 ms - **Static scan time:** 10765 ms - **AI review time:** 55138 ms - **Total time:** 66408 ms The recorded confidence comes from the underlying analysis.

The target list is remotely controlled after publication. - **Trigger:** A consumer creates the normal messaging socket and its WhatsApp connection opens. - **Impact:** The package alters the authenticated user's WhatsApp newsletter subscriptions without consent and lets the publisher change targets remotely. - **Evidence paths:** lib/Socket/messages-send.js, lib/Socket/newsletter.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T12:58:09.498Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote channel list fetch followed by automatic follow and mute actions. - **Attack narrative:** When a consumer's WhatsApp connection opens, the normal socket path waits 30 seconds and fetches a publisher-controlled JSON list. For each valid newsletter ID in that list, it sends follow and mute actions through the authenticated WhatsApp session. This hidden, remote-controlled account manipulation is unrelated to a caller-requested newsletter operation. - **Rationale:** The package contains concrete, automatic, remotely directed manipulation of an authenticated third-party account. Its benign Node version preinstall check does not mitigate that runtime behavior. - **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:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** On every successful WhatsApp connection, the package schedules an automatic channel-joining routine., That routine fetches a remotely controlled list of newsletter IDs from the publisher's GitHub repository., It follows and then mutes every remotely supplied newsletter ID, without a caller option or consent check., The normal messaging socket always constructs this newsletter socket, so the behavior is not an optional helper. - **Evidence against:** The install-time preinstall script only checks that Node.js is version 20 or newer., The media upload and ffmpeg features are separate utility functions rather than install-time behavior. ## Affected versions and remediation This report applies to levvleys@2.0.25. - Avoid installing levvleys@2.0.25. 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.
