## Verdict summary
**Blocked & quarantined** — Unexpected install-time network access and functionality suited to evading WhatsApp anti-spam controls.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Malware
- **Selected version:** 1.0.4
- **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: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

Installation automatically imports package code and connects to WhatsApp. At runtime, the package enables an aggressive anti-ban layer that changes sending behavior and can vary message content.

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:** Installation automatically imports package code and connects to WhatsApp. At runtime, the package enables an aggressive anti-ban layer that changes sending behavior and can vary message content.

- **Trigger:** npm installation, then creating a WhatsApp socket without setting antiban to false.

- **Impact:** Unexpected install-time network access and functionality suited to evading WhatsApp anti-spam controls.

- **Evidence paths:** package.json, scripts/self-test.js, lib/Socket/index.js, lib/antiban.js, README.md

- **Review source:** ai\_review

- **Reviewed:** 2026-09-30T10:35:08.617Z

### AI review details

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

- **Mechanism:** Automatic network self-test and default anti-ban message evasion controls.

- **Rationale:** This package contains real, automatically activated anti-detection capability and an unconsented install-time network probe. The source does not establish credential theft, destructive behavior, or a complete malicious lifecycle chain, so a warning is more proportionate than a block.

- **Files touched:** scripts/self-test.js, lib/index.js, lib/Socket/index.js, lib/antiban.js

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

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 91.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for block:** Install automatically runs a self-test that imports the package and opens a WebSocket to WhatsApp., The runtime enables an aggressive anti-ban wrapper unless the user explicitly disables it., The anti-ban module alters message text with zero-width characters and punctuation variation., README claims AntiBan is opt-in, but the runtime code enables it by default.

- **Evidence against:** The install hook targets WhatsApp rather than an unrelated collection endpoint., Webhook and Telegram alert delivery require caller-supplied configuration., No source evidence of credential harvesting, shell execution, or foreign project mutation was found.

## Affected versions and remediation

This report applies to my-baileys@1.0.4.

- Avoid installing my-baileys@1.0.4. 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.
