## Verdict summary
**Blocked & quarantined** — Uses the user’s WhatsApp account to follow a target the package publisher selected without a user request.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Block by default
- **Public report status:** Published
- **Threat category:** Malware
- **Selected version:** 8.0.5
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

LPM AI independently confirmed malicious behavior in this version and supplies the Firewall block.

AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy.

The package automatically uses the connected WhatsApp account to follow a publisher-selected newsletter whenever the message socket is created. This is an unauthorized account action and warrants blocking publication.

## Security analysis

### Published attack-surface review

- **Summary:** A socket created through the normal client path automatically follows a publisher-chosen WhatsApp newsletter.

- **Trigger:** Creating the message socket; the follow is attempted after a 90-second timer.

- **Impact:** Uses the user’s WhatsApp account to follow a target the package publisher selected without a user request.

- **Evidence paths:** lib/Socket/newsletter.js, lib/Socket/messages-send.js, lib/Socket/index.js

- **Review source:** ai\_review

- **Reviewed:** 2026-11-05T06:53:49.555Z

### AI review details

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

- **Mechanism:** A timer calls the newsletter query with a hard-coded newsletter ID and the FOLLOW action.

- **Attack narrative:** When the normal socket construction path creates a message socket, it also creates the newsletter socket. That socket schedules a follow after 90 seconds and sends a FOLLOW query for the hard-coded newsletter 120363400780200098@newsletter, using the user’s WhatsApp connection without an explicit request.

- **Rationale:** The package automatically uses the connected WhatsApp account to follow a publisher-selected newsletter whenever the message socket is created. This is an unauthorized account action and warrants blocking publication.

- **Network endpoints:** WhatsApp service (WABinary.S\_WHATSAPP\_NET)

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** Creating the message socket also creates the newsletter socket., The newsletter socket starts a timer that follows the hard-coded newsletter 120363400780200098@newsletter after 90 seconds., That follow action is sent as a WhatsApp newsletter query to the WhatsApp service.

- **Evidence against:** The preinstall script only checks the Node.js major version and exits if it is below 20., WhatsApp client and newsletter features are within the package’s stated purpose.

## Affected versions and remediation
