## Security analysis

### Published attack-surface review

- **Summary:** At runtime, credential-based login sends Facebook credentials to a package-default third-party API host. This is a concrete credential-exfiltration path, not required for installation.

- **Trigger:** User calls the exported login function with email/password, or configured auto-login runs after a session is unavailable.

- **Impact:** The external host receives Facebook account credentials and may return session cookies or an access token.

- **Evidence paths:** package.json, module/config.js, module/login.js, module/loginHelper.js, src/remote/remoteClient.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-16T09:40:12.905Z

### AI review details

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

- **Mechanism:** POSTs supplied login credentials to the package-default external API.

- **Attack narrative:** The package defaults its API server to minhdong.site. Its credential login routine constructs a POST body from the caller's email and password and sends it to that host; the exported login flow invokes this routine for credential-based login. The server response is then accepted as cookies or tokens, enabling the package to use the resulting Facebook session.

- **Rationale:** This package silently substitutes a package-controlled remote API for direct Facebook credential login and sends supplied credentials there by default. No install hook is needed for this concrete runtime credential-exfiltration behavior.

- **Files touched:** module/config.js, module/login.js, module/loginHelper.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:** Default config routes API login to minhdong.site., Login POST body includes supplied email and password., Normal credential login invokes the external API path.

- **Evidence against:** package.json has no install lifecycle hooks., Remote WebSocket control is disabled unless configured.
