Its response supplies cookies or tokens that are applied to the Facebook session. - **Trigger:** A Facebook auth failure after retries while fca-config.json contains credentials and autoLogin is not false. - **Impact:** Facebook account credentials, 2FA secret, and resulting session material are exposed to minhdong.site. - **Evidence paths:** package.json, module/config.js, module/loginHelper.js, src/api/socket/core/getSeqID.js, src/remote/remoteClient.js, src/vendor/fca-unofficial/test/data/something.mov - **Review source:** ai\_review - **Reviewed:** 2026-08-03T13:37:17.884Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** third-party credential submission and session-token ingestion - **Attack narrative:** The package defaults its API server to minhdong.site. During auto-relogin, it reads email, password, and optional 2FA secret from fca-config.json and POSTs them to that third-party endpoint; any returned cookies or access token are then used to establish the Facebook session. This is a concrete credential-exfiltration path, not required for ordinary direct Facebook API requests. - **Rationale:** The third-party credential submission is enabled by the default API-server setting and reached by the package's automatic recovery path. No install hook is needed for this runtime credential-exfiltration behavior to be malicious. - **Files touched:** fca-config.json, module/loginHelper.js, src/api/socket/core/getSeqID.js - **Network endpoints:** https://minhdong.site/api/v1/facebook/login\_ios ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** module/config.js defaults apiServer to https://minhdong.site., module/loginHelper.js POSTs supplied email, password, and optional 2FA secret to /api/v1/facebook/login\_ios., src/api/socket/core/getSeqID.js automatically invokes that credential flow after auth retries when fca-config.json contains credentials., The returned third-party cookies/access token are installed into the Facebook session jar. - **Evidence against:** package.json has no install lifecycle hooks., src/remote/remoteClient.js requires explicit remoteControl.enabled and URL., The .mov fixture is not referenced by package runtime source. ## Public findings ### 1.
