## Verdict summary
**Blocked & quarantined** — Unauthorized changes to the connected WhatsApp account's newsletter subscriptions.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Malware
- **Selected version:** 2.0.21
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

Trusted malware advisory MAL-2026-17397 identifies this version as malicious. 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.

When a WhatsApp socket opens, the package obtains newsletter identifiers from a maintainer-controlled remote file and mutates the connected account to follow them. The subscriptions are then muted, reducing their visibility to the account owner.

## Security analysis

### Published attack-surface review

- **Summary:** When a WhatsApp socket opens, the package obtains newsletter identifiers from a maintainer-controlled remote file and mutates the connected account to follow them. The subscriptions are then muted, reducing their visibility to the account owner.

- **Trigger:** Opening a WhatsApp connection through the package.

- **Impact:** Unauthorized changes to the connected WhatsApp account's newsletter subscriptions.

- **Evidence paths:** lib/Socket/newsletter.js

- **Review source:** ai\_review

- **Reviewed:** 2026-09-11T10:50:40.113Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Remote-controlled automatic newsletter follows and mutes.

- **Attack narrative:** After a socket reports an open connection, the package waits 30 seconds and downloads a JSON list from a GitHub-controlled URL. It accepts newsletter IDs from that response, sends WhatsApp follow requests for each one, and then sends mute requests. Because the server-side list is fetched at runtime, the publisher can change the subscriptions imposed on connected accounts without publishing a new package version.

- **Rationale:** The package contains a concealed, remotely controlled account-mutation path that automatically follows and mutes newsletters after connection. This is concrete unauthorized behavior, not a package-aligned media or WhatsApp transport feature.

- **Files touched:** lib/Socket/newsletter.js

- **Network endpoints:** raw.githubusercontent.com, s.whatsapp.net

### Review decision

- **Verdict:** Malicious

- **Confidence:** 98.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** A socket connection automatically retrieves a remotely controlled list of newsletter IDs., For every listed ID, it follows and then mutes the newsletter without an application-user request., The remote list can be changed after publication, controlling future account mutations.

- **Evidence against:** The install hook only checks that Node.js is version 20 or newer., No install-time network, file-harvesting, or project-file mutation was found.

## Affected versions and remediation

This report applies to levvleys@2.0.21.

- Avoid installing levvleys@2.0.21. 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.
