## Verdict summary
**Blocked & quarantined** — Changes the user's account by following channels they did not choose.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Block by default
- **Public report status:** Published
- **Threat category:** Malware
- **Selected version:** 5.5.0
- **Selected version is latest:** Yes
- **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 performs unsolicited WhatsApp account actions: socket creation schedules follows of four publisher-chosen newsletters, and connection startup follows another hard-coded channel by default. This is malicious under the account-action rule, even though following channels is otherwise a normal library capability.

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 publisher-selected WhatsApp channels using the user's account.

- **Trigger:** Default socket construction schedules newsletter follows; opening the connection triggers another follow.

- **Impact:** Changes the user's account by following channels they did not choose.

- **Evidence paths:** lib/Socket/index.js, lib/Socket/newsletter.js, lib/Socket/username.js, lib/Defaults/index.js

- **Review source:** ai\_review

- **Reviewed:** 2026-11-05T07:10:25.300Z

### AI review details

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

- **Mechanism:** The socket uses FOLLOW queries for hard-coded newsletter IDs. The main channel follow runs unless autoFollow is explicitly set to false; newsletter socket construction also schedules four delayed follows.

- **Attack narrative:** When the package creates its socket, it schedules four newsletter FOLLOW requests for hard-coded IDs. Once connected, it also follows a hard-coded update channel by default; users must opt out with autoFollow: false. These actions use the user's WhatsApp account without a request to follow those channels.

- **Rationale:** The package performs unsolicited WhatsApp account actions: socket creation schedules follows of four publisher-chosen newsletters, and connection startup follows another hard-coded channel by default. This is malicious under the account-action rule, even though following channels is otherwise a normal library capability.

- **Files touched:** lib/Socket/index.js, lib/Socket/newsletter.js, lib/Socket/username.js, lib/Defaults/index.js

- **Network endpoints:** WhatsApp newsletter service, wss://web.whatsapp.com/ws/chat

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** Socket creation defaults autoFollow to true and, after the WhatsApp connection opens, follows a hard-coded channel; the code documents only an opt-out., Creating the newsletter socket schedules four more hard-coded newsletter follows, decoding their IDs and issuing FOLLOW queries after delays., The newsletterFollow method sends the requested newsletter ID through the WhatsApp newsletter FOLLOW operation.

- **Evidence against:** The preinstall hook only checks the Node.js major version and exits on versions below 20., The package describes itself as a WhatsApp Web interaction library, so its normal socket and newsletter operations fit its stated purpose.

## Affected versions and remediation

This report applies to @zyrennofficiall/baileys@5.5.0.

- Avoid installing @zyrennofficiall/baileys@5.5.0. 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.
