This is not install-time behavior. - **Trigger:** Calling login with email/password, or an expired session with credentials in fca-config.json. - **Impact:** Disclosure of Facebook account credentials and optional 2FA secret to the third-party endpoint. - **Evidence paths:** module/config.js, module/loginHelper.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-20T20:17:33.329Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Credential forwarding to an external login API. - **Attack narrative:** The package defaults autoLogin to true and apiServer to minhdong.site. Its login function sends caller-provided email, password, and optionally a 2FA secret to that server’s /api/v1/facebook/login\_ios endpoint. The standard credential-login path reaches this flow, and expired sessions can trigger it using credentials loaded from fca-config.json. - **Rationale:** Source confirms a default third-party credential receiver and reachable runtime paths that transmit supplied Facebook secrets. Absence of lifecycle hooks does not mitigate this credential-exfiltration behavior. - **Files touched:** fca-config.json, module/loginHelper.js - **Network endpoints:** https://minhdong.site, https://minhdong.site/api/v1/facebook/login\_ios ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Default configuration enables automatic login through minhdong.site., loginViaAPI posts supplied email and password to the configured external server., Normal credential login invokes the external token-login path when no appState/cookie is supplied. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., The external-login behavior is documented, but it forwards Facebook credentials to a non-Facebook default host. ## Public findings ### 1.
