## Verdict summary
**Blocked & quarantined** — Causes an unrequested outbound connection at install time and mutates the user's WhatsApp channel subscriptions at runtime.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Malware
- **Selected version:** 1.0.2
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

Trusted malware advisory MAL-2026-17400 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.

Installation automatically contacts WhatsApp. Creating a socket with default options automatically follows the maintainer-controlled newsletter on the user's WhatsApp account.

## Security analysis

### Published attack-surface review

- **Summary:** Installation automatically contacts WhatsApp. Creating a socket with default options automatically follows the maintainer-controlled newsletter on the user's WhatsApp account.

- **Trigger:** npm installation, then the first successful WhatsApp socket connection.

- **Impact:** Causes an unrequested outbound connection at install time and mutates the user's WhatsApp channel subscriptions at runtime.

- **Evidence paths:** package.json, scripts/self-test.js, lib/Defaults/index.js, lib/Socket/newsletter.js

- **Review source:** ai\_review

- **Reviewed:** 2026-09-09T12:05:56.695Z

### AI review details

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

- **Mechanism:** Postinstall network probe and default hard-coded newsletter follow.

- **Attack narrative:** The package runs a postinstall script that contacts WhatsApp. Separately, its default socket configuration contains a hard-coded newsletter identifier; when a user connects, the code sends a follow request for that channel. The package then allowlists that same channel while denying other follow requests. Source comments attempt to distinguish this behavior from a hidden version, but the operation remains a default, unrequested change to the user's external account.

- **Rationale:** This package performs unrequested network activity during installation and automatically changes a user's WhatsApp channel subscriptions through a hard-coded maintainer channel. The opt-out setting does not establish prior consent for a default external-account mutation.

- **Files touched:** package.json, scripts/self-test.js, lib/Defaults/index.js, lib/Socket/newsletter.js

- **Network endpoints:** wss://web.whatsapp.com/ws/chat

### Review decision

- **Verdict:** Malicious

- **Confidence:** 94.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** The postinstall hook executes a package script automatically., That script imports package code and opens a WebSocket to WhatsApp during installation., A hard-coded WhatsApp newsletter is enabled as the default configuration., On the first successful socket connection, the library follows that newsletter on the user's account., The channel-follow guard permanently allowlists the maintainer's channel while blocking other channels., Comments portray the automatic follow as acceptable by contrasting it with an alleged hidden implementation.

- **Evidence against:** No credential harvesting or secret exfiltration was found in the inspected lifecycle code., The installation connectivity check has a documented environment-variable skip and exits successfully.

## Affected versions and remediation

This report applies to my-baileys@1.0.2.

- Avoid installing my-baileys@1.0.2. 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.
