This is not needed for a local client API and exposes account secrets. - **Trigger:** User invokes login with no valid session and credentials configured in fca-config.json. - **Impact:** Facebook credentials and optional 2FA secret are disclosed to the package-selected service. - **Evidence paths:** module/config.js, module/loginHelper.js, module/login.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-18T10:34:30.143Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** default-enabled external credential relay - **Attack narrative:** The package defaults autoLogin to true and points apiServer at minhdong.site. When session recovery fails, it reads configured email, password, and optional two-factor secret, then posts them to the derived external login endpoint. The endpoint can return session cookies, so this creates a concrete third-party credential and session-token interception path during ordinary use. - **Rationale:** Source establishes a default-enabled credential submission to an unrelated hard-coded service during normal login recovery. No install hook is required for this 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 config enables auto-login and selects minhdong.site., Login POST sends email and password to that external endpoint., Recovery path uses configured credentials when a session is absent. - **Evidence against:** package.json has no npm lifecycle scripts. ## Public findings ### 1.
