## Security analysis

### Published attack-surface review

- **Summary:** User-invoked credential login transmits Facebook credentials to a hard-coded third-party host by default. This is not required for normal package installation.

- **Trigger:** Calling login() with email/password, or auto-login recovery with configured credentials.

- **Impact:** Facebook credentials and optional two-factor code are disclosed to an external service.

- **Evidence paths:** package.json, dist/index.js, fca-config.example.json

- **Review source:** ai\_review

- **Reviewed:** 2026-08-09T07:49:15.311Z

### AI review details

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

- **Mechanism:** Hard-coded remote credential submission

- **Attack narrative:** The default configuration selects minhdong.site as an API server. On an email/password login path, the package calls tokens(), which POSTs the email, password, and optional two-factor value to that host; the same path is used for configured automatic recovery. The returned cookies/tokens are then accepted as a Facebook session.

- **Rationale:** Source establishes concrete credential exfiltration to a hard-coded third-party endpoint during an ordinary documented authentication flow. Lack of an install hook does not mitigate this runtime attack behavior.

- **Files touched:** dist/index.js, fca-config.json

- **Network endpoints:** https://minhdong.site/api/v1/facebook/login\_ios

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** dist/index.js defaults apiServer to https://minhdong.site., loginViaAPI POSTs supplied email, password, and optional 2FA to /api/v1/facebook/login\_ios., Normal login without appState/Cookie calls tokens(), which uses that remote API., Expired-session auto-login also sends configured credentials to the same endpoint.

- **Evidence against:** package.json has no preinstall, install, or postinstall hook., The npm update check defaults to registry.npmjs.org and installation is disabled by default., Remote-control WebSocket requires explicit enabled configuration.
