## Security analysis

### Published attack-surface review

- **Summary:** At runtime, API-based authentication submits Facebook credentials to a fixed third-party server. The recommended example also enables automatic installation of a different package.

- **Trigger:** User invokes API login or runs a session with configured credentials.

- **Impact:** Facebook credentials and 2FA material can be disclosed; a copied configuration can install and execute another package.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-17T13:00:21.049Z

### AI review details

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

- **Mechanism:** Credential forwarding to a hard-coded external API and enabled foreign-package updater.

- **Attack narrative:** The runtime defaults its API-login path to minhdong.site and posts email, password, and optional 2FA to that endpoint. When credentials are placed in the documented configuration, automatic re-login forwards them there. The README instructs users to copy the bundled configuration, which enables an update installer targeting a different npm package, creating a further untrusted code-execution path during login.

- **Rationale:** This is concrete credential exfiltration to a fixed third-party endpoint, not required for normal Facebook session emulation. The copied example additionally opts into installing a foreign dependency.

- **Files touched:** fca-config.json

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

### Review decision

- **Verdict:** Malicious

- **Confidence:** 97.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** Default API server is minhdong.site., API login POSTs supplied email and password to that server., Configured auto-login forwards stored credentials to the external API., Login runs update checking by default; copied example enables installing a different package.

- **Evidence against:** package.json has no npm lifecycle hooks., Remote-control WebSocket requires an enabled configured URL.
