## Security analysis

### Published attack-surface review

- **Summary:** A runtime login path sends Facebook credentials and optional 2FA material to a hard-coded third-party service. It is activated by calling the package login API without a valid existing session.

- **Trigger:** User calls login with email/password, or configured auto-login recovers an expired session.

- **Impact:** Facebook credentials, optional 2FA secret, and returned session material are exposed to an unrelated host.

- **Evidence paths:** index.js, module/login.js, module/loginHelper.js, module/config.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-22T04:08:47.418Z

### AI review details

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

- **Mechanism:** Third-party credential relay

- **Attack narrative:** The package’s exported login flow passes caller credentials to loginHelper. Its default configuration selects minhdong.site, then constructs a request body containing email, password, and optional two-factor secret and POSTs it to that host. This is a concrete credential-exfiltration path disguised as Facebook login functionality.

- **Rationale:** The hard-coded third-party authentication endpoint receives raw user credentials at runtime, which is not required for a local Facebook API client. No install hook is needed for this concrete credential-exfiltration behavior.

- **Files touched:** index.js, module/login.js, module/loginHelper.js, module/config.js

- **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 configuration routes authentication to minhdong.site., Login POSTs supplied email, password, and optional 2FA secret to that external host., The exported login flow invokes this credential relay when no valid session is available.

- **Evidence against:** package.json has no install lifecycle hooks., Remote-control WebSocket support is disabled by default and requires a user URL.
