## Verdict summary
**Blocked & quarantined** — The connected WhatsApp account is subscribed to that newsletter.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Malware
- **Selected version:** 7.2.0
- **Selected version is latest:** No
- **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.

Source confirms an automatic, publisher-selected account action whenever the socket connects. This is concrete attack behavior and supports blocking the package.

## Security analysis

### Published attack-surface review

- **Summary:** The socket implementation automatically follows a publisher-selected WhatsApp newsletter after connection. This changes the connected account’s subscriptions without a request from the caller.

- **Trigger:** A consumer creates a socket and its connection opens.

- **Impact:** The connected WhatsApp account is subscribed to that newsletter.

- **Evidence paths:** package.json, lib/Socket/index.js, lib/Socket/newsletter.js

- **Review source:** ai\_review

- **Reviewed:** 2026-10-17T16:40:26.505Z

### AI review details

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

- **Mechanism:** A connection event handler calls newsletterFollow with a hard-coded newsletter ID.

- **Attack narrative:** On connection, the library follows a fixed newsletter on the user’s WhatsApp account. The caller does not choose that newsletter or enable the action. The newsletter API sends the join request, making this an automatic account change through the normal socket entrypoint.

- **Rationale:** Source confirms an automatic, publisher-selected account action whenever the socket connects. This is concrete attack behavior and supports blocking the package.

- **Files touched:** package.json, lib/Socket/index.js, lib/Socket/newsletter.js

### Review decision

- **Verdict:** Malicious

- **Confidence:** 98.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for block:** The package entrypoint is lib/index.js, which exposes the socket implementation., When a socket connection opens, the library automatically follows a hard-coded newsletter once, without a caller-selected target or opt-in., newsletterFollow sends a join request for the supplied newsletter ID.

## Affected versions and remediation

This report applies to @hanzofc/baileys@7.2.0.

- Avoid installing @hanzofc/baileys@7.2.0. 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.
