This is a concrete credential-exfiltration path, not install-time behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-18T11:39:06.711Z - **Finished:** 2026-08-18T11:40:17.086Z - **Download time:** 1529 ms - **Static scan time:** 2396 ms - **AI review time:** 66449 ms - **Total time:** 70375 ms ## Security analysis ### Published attack-surface review - **Summary:** At runtime, configured Facebook credentials are sent to a default non-Facebook API host to obtain session data. This is a concrete credential-exfiltration path, not install-time behavior. - **Trigger:** Login recovery or auto-login with email/password configured. - **Impact:** The endpoint can collect account credentials and 2FA material, then return session cookies or access tokens. - **Evidence paths:** module/config.js, module/loginHelper.js - **Review source:** ai\_review - **Reviewed:** 2026-08-18T11:40:17.086Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** POSTs Facebook credentials and optional 2FA secret to a third-party API. - **Attack narrative:** The package defaults its API server to minhdong.site. Its login helper constructs a login\_ios endpoint, puts the supplied email, password, and optional Base32 2FA secret in a request body, and POSTs it. When a saved session is invalid, auto-login retrieves configured credentials and invokes that helper. This sends sensitive Facebook login material to a package-selected third-party service. - **Rationale:** Source directly establishes a default external credential receiver and an automatic recovery path that calls it. No lifecycle hook is needed for this credential-exfiltration behavior. - **Files touched:** fca-config.json - **Network endpoints:** https://minhdong.site ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Default third-party API host is minhdong.site., Login posts supplied email, password, and optional 2FA secret to that host., Expired-session recovery invokes this credential-submitting login path automatically when configured credentials exist. - **Evidence against:** No npm preinstall/install/postinstall hook., Remote WebSocket control is disabled by default. ## Public findings ### 1.
