This is a concrete credential-exfiltration path, not required for ordinary package installation. - **Trigger:** A consumer enables autoLogin, configures credentials, and an existing Facebook session is expired or invalid. - **Impact:** The third party can receive account passwords and two-factor authentication seeds, enabling account compromise. - **Evidence paths:** module/config.js, module/loginHelper.js, module/login.js, src/api/socket/core/getSeqID.js - **Review source:** ai\_review - **Reviewed:** 2026-08-29T12:22:26.060Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Posts configured login credentials to an external credential-broker endpoint. - **Attack narrative:** The package defines a default external login service at minhdong.site. When auto-login is enabled after a session failure, it reads configured Facebook credentials, including an optional TOTP seed, and posts them to that service. The server response may provide cookies or an access token that the package then uses as the Facebook session. Although this behavior is guarded by configuration, a package-owned default third-party credential broker creates a direct account-credential exfiltration path. - **Rationale:** Source inspection confirms a runtime path that transmits passwords and optional TOTP seeds to a hard-coded third-party host. The opt-in guard reduces accidental activation but does not remove the concrete credential-exfiltration capability. - **Files touched:** fca-config.json - **Network endpoints:** https://minhdong.site/api/v1/facebook/login\_ios ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The login helper posts the supplied Facebook email and password to a hard-coded third-party host., It also sends a supplied TOTP seed to that host., The credential transfer runs when configured auto-login handles an expired session. - **Evidence against:** There are no npm install lifecycle hooks., The credential-relogin path requires autoLogin to be enabled and credentials to be configured., Remote WebSocket control is disabled unless separately configured. ## Public findings ### 1.
