## Verdict summary
**Blocked & quarantined** — A remote package operator can cause connected accounts to follow arbitrary newsletters and conceal them by muting them.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Malware
- **Selected version:** 2.0.11
- **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 silently follows and mutes newsletters chosen by a remotely fetched list. This changes the connected user's WhatsApp account state without a user action.

## Security analysis

### Published attack-surface review

- **Summary:** When a WhatsApp socket opens, the package silently follows and mutes newsletters chosen by a remotely fetched list. This changes the connected user's WhatsApp account state without a user action.

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

- **Impact:** A remote package operator can cause connected accounts to follow arbitrary newsletters and conceal them by muting them.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-09-09T23:59:43.960Z

### AI review details

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

- **Mechanism:** Remote list retrieval followed by automatic WhatsApp newsletter subscription mutations.

- **Attack narrative:** After a connection opens, the package waits 30 seconds and fetches a JSON list from a GitHub-controlled URL. For every valid newsletter ID in that list, it sends WhatsApp follow and mute operations through the authenticated socket. The remote list can change the targets without a package update, and the behavior is not exposed as an explicit user command.

- **Rationale:** The package contains a concealed, remotely directed mutation of the authenticated user's WhatsApp newsletter subscriptions. Its harmless Node-version preinstall check does not mitigate this runtime behavior.

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

- **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:** On every successful WhatsApp connection, the package schedules hidden channel automation., It downloads a remotely controlled list of newsletter IDs from GitHub., It follows each remotely supplied newsletter and then mutes it using the connected user's WhatsApp session.

- **Evidence against:** The preinstall hook only rejects Node.js versions below 20., No credential harvesting or local secret exfiltration was found in the inspected attack path.

## Affected versions and remediation

This report applies to levvleys@2.0.11.

- Avoid installing levvleys@2.0.11. 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.
