The returned cookies can become the caller's Facebook session. - **Trigger:** A consumer calls the exported login function with an email and password, or enables automatic login with credentials in fca-config.json. - **Impact:** A third party can receive Facebook passwords, optional two-factor secrets, and issue session cookies or access tokens. - **Evidence paths:** module/config.js, module/login.js, module/loginHelper.js, src/api/socket/core/getSeqID.js - **Review source:** ai\_review - **Reviewed:** 2026-08-29T19:25:48.999Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Credential forwarding to a third-party login service followed by session-cookie installation. - **Attack narrative:** The package exposes a normal Facebook login interface, but its credential path forwards the supplied email, password, and optional two-factor secret to minhdong.site. It accepts cookies and tokens returned by that server, then installs the cookies into its Facebook session jar. This gives the third-party service both account credentials and a path to provide or control an authenticated session. - **Rationale:** This is concrete credential exfiltration to a package-selected third-party endpoint during normal runtime login. The absence of install hooks does not remove the risk to consumers who authenticate through the package. - **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:** The default configuration selects a third-party login server, minhdong.site., The login request sends the supplied email, password, and optional two-factor secret to that server., The normal credential-login path calls the external token-login function and installs returned cookies as a Facebook session. - **Evidence against:** The package has no npm install lifecycle hook., External automatic login is disabled by default, although ordinary credential login still uses the external service., The separate remote-control WebSocket feature is disabled unless configured. ## Public findings ### 1.
