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 standard WhatsApp socket connection triggers a remote fetch and changes the connected account's newsletter subscriptions. Remote data selects which newsletters are followed and muted. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-11T09:15:26.357Z - **Finished:** 2026-09-11T09:17:40.056Z - **Download time:** 509 ms - **Static scan time:** 9548 ms - **AI review time:** 123640 ms - **Total time:** 133699 ms The recorded confidence comes from the underlying analysis.

Remote data selects which newsletters are followed and muted. - **Trigger:** A consumer creates a package socket and it reaches the open connection state. - **Impact:** The connected WhatsApp account is silently subscribed to channels chosen by the package author. - **Evidence paths:** lib/Socket/messages-send.js, lib/Socket/newsletter.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T09:17:40.056Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote-controlled automatic newsletter follow and mute actions. - **Attack narrative:** The normal socket hierarchy constructs the newsletter layer. Thirty seconds after a WhatsApp connection opens, that layer downloads an array of newsletter IDs from a GitHub-controlled URL. For each valid ID, it sends follow and mute actions through the authenticated WhatsApp session. This is an unconsented account mutation controlled by remote content, not a user-requested newsletter operation. - **Rationale:** The package embeds a remote-controlled, automatic account-subscription action in its standard runtime connection path. Its benign lifecycle version check does not mitigate that concrete behavior. - **Network endpoints:** raw.githubusercontent.com ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The normal message-socket construction path includes the newsletter socket layer., On connection, the newsletter layer fetches attacker-controlled channel identifiers from GitHub., It automatically follows and then mutes every remotely supplied newsletter identifier without user consent. - **Evidence against:** The install hook only checks the Node.js major version and exits on unsupported versions., The media upload and dynamic-import code is callable utility functionality, not the decisive behavior. ## Affected versions and remediation This report applies to levvleys@2.0.18. - Avoid installing levvleys@2.0.18. 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.
