## Security analysis

### Published attack-surface review

- **Summary:** A runtime login without an existing AppState or cookie sends the caller-provided Facebook email and password to a default third-party host. This is credential exfiltration, not needed for importing the package.

- **Trigger:** Caller invokes login with email/password and no AppState or Cookie.

- **Impact:** Third party can capture credentials and return an account session.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-14T13:06:56.839Z

### AI review details

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

- **Mechanism:** POSTs supplied Facebook credentials to a hardcoded external login API.

- **Attack narrative:** The package defaults apiServer to minhdong.site. Its credential-login flow constructs a body containing the supplied email and password, then POSTs it to /api/v1/facebook/login\_ios. The ordinary login path reaches this flow when the caller supplies credentials instead of an existing AppState or Cookie. The response is accepted as cookies/access tokens, making the third-party endpoint able to capture credentials and supply a session.

- **Rationale:** Source confirms a default third-party credential receiver in the standard runtime login path. Absence of install hooks does not mitigate this concrete credential-exfiltration behavior.

- **Files touched:** module/config.js, module/login.js, module/loginHelper.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 selects third-party minhdong.site as the login API., The API-login routine builds a body containing the supplied email and password., It POSTs that credential body to the third-party login endpoint., Normal credential login invokes the tokens API when no AppState or cookie is supplied.

- **Evidence against:** package.json has no preinstall, install, or postinstall hook., The package entrypoint only exports APIs; no network request occurs on import., Remote WebSocket control is disabled unless explicitly configured.
