This is activated by normal email/password login or configured auto-login. - **Trigger:** Consumer calls login with email/password, or recovery invokes configured auto-login. - **Impact:** Third party can receive account credentials and return session cookies or access tokens. - **Evidence paths:** package.json, module/config.js, module/login.js, module/loginHelper.js, src/remote/remoteClient.js - **Review source:** ai\_review - **Reviewed:** 2026-08-21T18:53:49.219Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** POSTs credentials and optional 2FA secret to a package-default external login API. - **Attack narrative:** The package defaults its login server to minhdong.site. Its login helper builds a body containing the caller's email and password, optionally adds the 2FA secret, and POSTs it to that server. The standard email/password login flow invokes this helper, so the transfer is not limited to an explicit opt-in integration. The server response is then used to establish Facebook cookies and an access token. - **Rationale:** Source inspection confirms a runtime credential-exfiltration path to a hard-coded third-party endpoint during ordinary login. No install hook is needed for this concrete malicious behavior. - **Files touched:** module/config.js, module/login.js, module/loginHelper.js - **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:** Default config selects a third-party API server and stores login credentials., The API-login routine POSTs supplied email, password, and optional 2FA secret to that server., The normal email/password login path calls this API-login routine. - **Evidence against:** package.json contains no preinstall, install, or postinstall hook., Remote-control WebSocket behavior is disabled by default and requires a configured URL. ## Public findings ### 1.
