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 normal connection opening causes unrequested account actions. The package retrieves remotely selected WhatsApp newsletter IDs and follows and mutes them with the consumer's authenticated session. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-11T10:49:48.942Z - **Finished:** 2026-09-11T10:50:44.837Z - **Download time:** 505 ms - **Static scan time:** 9915 ms - **AI review time:** 45474 ms - **Total time:** 55895 ms The recorded confidence comes from the underlying analysis.

The package retrieves remotely selected WhatsApp newsletter IDs and follows and mutes them with the consumer's authenticated session. - **Trigger:** A consumer creates a socket and its WhatsApp connection reaches the open state. - **Impact:** The package operator can enroll a consumer account in arbitrary newsletters without user consent and alter its notification state. - **Evidence paths:** lib/Socket/newsletter.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T10:50:44.837Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote-controlled automatic newsletter follows using the authenticated WhatsApp session. - **Attack narrative:** After a socket connects, the package waits 30 seconds, downloads a mutable list from the publisher's GitHub repository, and follows every listed newsletter through the consumer's authenticated WhatsApp session. It then mutes each channel and suppresses failures. This is concealed, remotely controlled account manipulation unrelated to an explicit caller request. - **Rationale:** The connection-triggered, remotely controlled use of a consumer's authenticated account to follow and mute arbitrary newsletters is concrete unauthorized behavior. The lifecycle hook is benign but does not mitigate the runtime attack. - **Files touched:** lib/Socket/newsletter.js, package.json, engine-requirements.js - **Network endpoints:** raw.githubusercontent.com, web.whatsapp.com ### 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 library waits 30 seconds then starts an automatic channel-joining routine., The routine downloads a maintainer-controlled list of newsletter IDs, follows each ID using the authenticated session, then mutes it; errors are silently ignored., The manifest also runs a preinstall script, although that script only checks the Node.js major version. - **Evidence against:** The inspected preinstall code only rejects Node.js versions below 20 and performs no network or file mutation., The flagged media helper's network and process use supports caller-requested media upload/conversion, not the connection-triggered follow behavior. ## Affected versions and remediation This report applies to levvleys@2.0.22. - Avoid installing levvleys@2.0.22. 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.
