## Security analysis

### Published attack-surface review

- **Summary:** Automatically follows two hardcoded WhatsApp newsletters using the connected account.

- **Trigger:** A created socket receives a connection-open event.

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

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

- **Review source:** ai\_review

- **Reviewed:** 2026-11-05T07:11:59.587Z

### AI review details

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

- **Mechanism:** The callback decodes two hardcoded newsletter IDs and sends FOLLOW requests, delayed by 90 and 180 seconds.

- **Attack narrative:** When an application creates and connects the package’s socket, the newsletter layer automatically follows two hardcoded newsletter IDs (120363400505489366@newsletter and 120363430764800148@newsletter). It sends the follow requests through WhatsApp after 90 and 180 seconds, without an explicit user request. This uses the connected account to take publisher-chosen account actions.

- **Rationale:** The package automatically follows two hardcoded WhatsApp newsletters when its socket connects, without the user requesting those account actions. This is malicious account manipulation.

- **Network endpoints:** s.whatsapp.net

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** The exported socket builder reaches the message and newsletter socket layers, registering this behavior during ordinary socket creation., On connection open, the code schedules WhatsApp newsletter FOLLOW requests for two hardcoded, base64-encoded newsletter IDs, 90 seconds apart., The requests use the WhatsApp MEX endpoint and the package’s FOLLOW query operation.

## Affected versions and remediation

This report applies to xzvbailss@1.0.0.

- Avoid installing xzvbailss@1.0.0. 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.
