This is credential exfiltration, not a required Facebook API request. - **Trigger:** Consumer calls the exported login API with email/password or enables configured auto-login. - **Impact:** Third party can capture account credentials and 2FA material, enabling account takeover. - **Evidence paths:** module/config.js, module/login.js, module/loginHelper.js, src/api/socket/core/getSeqID.js - **Review source:** ai\_review - **Reviewed:** 2026-08-23T12:10:47.132Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** POSTs supplied Facebook credentials and optional 2FA secret to a package-default external API. - **Attack narrative:** The exported login flow passes consumer-supplied credentials into loginHelper. Its default configuration selects minhdong.site, constructs a request body with email, password, and optional twoFactor, then POSTs it to that host. The response is used to establish Facebook cookies, so the external service is positioned to receive reusable account credentials during ordinary package use. - **Rationale:** Source directly establishes a default third-party credential collection endpoint in the normal login path. No install hook is needed for the concrete runtime credential-exfiltration behavior. - **Files touched:** 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 configuration routes API login to minhdong.site., Login code builds a body containing email, password, and optional twoFactor., That body is POSTed to the configured external endpoint during login. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., External remote-control WebSocket is disabled by default. ## Public findings ### 1.
