## Verdict summary
**Blocked & quarantined** — Uses the user's account to follow channels without an explicit request; the remote list can choose the targets.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Malware
- **Selected version:** 1.0.0
- **Selected version is latest:** Yes
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

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

The package follows remotely selected WhatsApp newsletters using the user's authenticated account by default after socket setup. This is an unrequested account action, so the package is malicious.

The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs.

## Security analysis

### Published attack-surface review

- **Summary:** Automatically follows newsletter channels chosen by a remotely fetched list using the user's WhatsApp account.

- **Trigger:** Creating the socket and logging in; the action runs after a delay unless BAILEYS\_AUTO\_FOLLOW is set to "off".

- **Impact:** Uses the user's account to follow channels without an explicit request; the remote list can choose the targets.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-11-02T19:41:41.899Z

### AI review details

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

- **Mechanism:** Fetches newsletter IDs from a hard-coded FinzzCloud endpoint or an environment override, then sends a FOLLOW action for each valid ID through the authenticated WhatsApp socket.

- **Attack narrative:** When the newsletter socket is created and a WhatsApp account is logged in, the package fetches a list of channels from a FinzzCloud endpoint and follows each returned newsletter through that account. This unsolicited account action is enabled by default; the opt-out environment variable does not make it user-requested.

- **Rationale:** The package follows remotely selected WhatsApp newsletters using the user's authenticated account by default after socket setup. This is an unrequested account action, so the package is malicious.

- **Network endpoints:** https://ch-finzzcloud.vercel.app/lyyn

### Review decision

- **Verdict:** Malicious

- **Confidence:** 98.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** Newsletter socket setup calls loadBase automatically; auto-follow is enabled by default unless BAILEYS\_AUTO\_FOLLOW is set to "off"., loadBase fetches a newsletter list from https://ch-finzzcloud.vercel.app/lyyn, or from the BAILEYS\_CH\_LIST\_URL override., For each returned newsletter ID, loadBase calls the WhatsApp newsletter query with the FOLLOW action., The newsletter query sends through the socket's WhatsApp query function.

- **Evidence against:** The package describes itself as a WhatsApp WebSocket API, so its normal use involves authenticated WhatsApp connections., The newsletter-follow code waits for a logged-in account ID before acting.

## Affected versions and remediation
