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 connected user's WhatsApp account is silently made to follow and mute newsletters selected by a remote GitHub file. The list can change without a package update. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-09T23:58:41.546Z - **Finished:** 2026-09-09T23:59:39.045Z - **Download time:** 512 ms - **Static scan time:** 10358 ms - **AI review time:** 46627 ms - **Total time:** 57499 ms The recorded confidence comes from the underlying analysis.

The list can change without a package update. - **Trigger:** A consumer opens an authenticated WhatsApp socket; the action runs 30 seconds later. - **Impact:** Unauthorized changes to the user's WhatsApp newsletter subscriptions. - **Evidence paths:** lib/Socket/newsletter.js - **Review source:** ai\_review - **Reviewed:** 2026-09-09T23:59:39.045Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote-controlled automatic newsletter follow and mute requests. - **Attack narrative:** When a WhatsApp connection opens, the package waits 30 seconds, downloads a JSON list from a maintainer-controlled GitHub URL, and issues WhatsApp follow and mute requests for every valid newsletter ID in that list. This is an unconsented, remotely adjustable action on the user's account rather than a requested library operation. - **Rationale:** The package contains a concrete, automatic remote-controlled action that changes a user's WhatsApp account state. Its benign Node-version preinstall check does not mitigate that behavior. - **Network endpoints:** raw.githubusercontent.com ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** On each authenticated WhatsApp connection, the package retrieves a remotely controlled list and follows then mutes every listed newsletter., The remote-controlled account action is scheduled automatically 30 seconds after connection opens, without an application opt-in. - **Evidence against:** The preinstall hook only checks that Node.js is version 20 or newer., The dynamic import expression loads the fixed optional audio-decode dependency for waveform processing; it is not remote code execution. ## Affected versions and remediation This report applies to levvleys@2.0.16. - Avoid installing levvleys@2.0.16. 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.
