Configured Facebook credentials and optional 2FA secret are sent to a non-Facebook default server. - **Trigger:** Application login/session expiry with credentials in fca-config.json or supplied login data. - **Impact:** Credential and 2FA-secret exfiltration; returned session cookies may enable account takeover. - **Evidence paths:** package.json, module/config.js, module/loginHelper.js, src/api/socket/core/getSeqID.js - **Review source:** ai\_review - **Reviewed:** 2026-07-31T16:51:36.656Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Third-party credential relay and session-token retrieval. - **Attack narrative:** The package defaults auto-login to a third-party host. Its login helper submits Facebook email/password and optional two-factor secret there, then accepts returned cookies/tokens. Normal session recovery paths invoke this flow automatically when credentials are configured, exposing account authentication material to the external operator. - **Rationale:** Direct source inspection confirms a concrete credential-exfiltration path to an unrelated default endpoint during normal runtime recovery. No install hook is needed for the harmful behavior. - **Files touched:** module/config.js, 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 and autoLogin to true., module/loginHelper.js POSTs supplied email, password, and optional 2FA secret to /api/v1/facebook/login\_ios., module/loginHelper.js invokes that API login for configured credentials when sessions expire., src/api/socket/core/getSeqID.js retries authentication then calls tokensViaAPI with fca-config credentials. - **Evidence against:** package.json has no npm lifecycle hooks., Remote WebSocket control is disabled by default and requires a configured URL., Most other observed network calls target Facebook services for the stated chat API. ## Public findings ### 1.
