Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. An opted-in recovery path transmits Facebook credentials and an optional 2FA secret to minhdong.site. The response is used to establish a Facebook session. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-08-25T02:28:22.080Z - **Finished:** 2026-08-25T02:29:20.242Z - **Download time:** 1007 ms - **Static scan time:** 2537 ms - **AI review time:** 54616 ms - **Total time:** 58162 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** An opted-in recovery path transmits Facebook credentials and an optional 2FA secret to minhdong.site. The response is used to establish a Facebook session. - **Trigger:** Runtime login with autoLogin enabled, configured credentials, and an invalid or expired session. - **Impact:** Facebook account credentials and 2FA material can be exfiltrated to the endpoint operator. - **Evidence paths:** module/config.js, module/loginHelper.js, module/login.js, index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-25T02:29:20.242Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Third-party credential relay for session recovery. - **Rationale:** The source implements a concrete credential-exfiltration path to a non-Facebook default host. Although gated by an opt-in setting, its purpose is to forward supplied secrets to that host and trust the returned session. Product guard normalized a non-low false-positive publish\_block request to warn-only suspicious. - **Files touched:** fca-config.json - **Network endpoints:** https://minhdong.site/api/v1/facebook/login\_ios ### Review decision - **Verdict:** Suspicious - **Confidence:** 96.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Malware - **False-positive risk:** Medium - **Evidence for warning:** Runtime login code posts supplied email, password, and optional 2FA secret to a third-party default endpoint., The endpoint response is accepted for Facebook session cookies/access tokens, making credential collection central to the flow., When enabled, auto-login invokes that credential-sending flow after a session failure. - **Evidence against:** package.json has no install lifecycle hook., The credential flow is disabled by default and requires autoLogin plus configured credentials., No import-time network request was found in the inspected entrypoint. ## Affected versions and remediation This report applies to @eryxenx/fca@1.0.6. - Review the evidence and your use of @eryxenx/fca@1.0.6 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
