Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The runtime sends configured Facebook credentials to a hard-coded non-Facebook server during automatic relogin. The server response can include cookies that the package uses to restore the Facebook session. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-20T00:09:28.957Z - **Finished:** 2026-09-20T00:10:48.898Z - **Download time:** 2025 ms - **Static scan time:** 2145 ms - **AI review time:** 75770 ms - **Total time:** 79941 ms The recorded confidence comes from the underlying analysis.

The server response can include cookies that the package uses to restore the Facebook session. - **Trigger:** MQTT authentication repeatedly fails while fca-config.json contains login credentials and automatic login remains enabled. - **Impact:** The external server receives Facebook login credentials and optional two-factor secret, enabling account compromise. - **Evidence paths:** module/config.js, module/loginHelper.js, src/api/socket/core/getSeqID.js - **Review source:** ai\_review - **Reviewed:** 2026-09-20T00:10:48.898Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic credential forwarding to a hard-coded external login API. - **Attack narrative:** The package defaults to an external API server and automatic login. On repeated MQTT authentication failure, it loads credentials from fca-config.json, builds a request containing email, password, and optional two-factor secret, and POSTs it to that server. This is an unrestricted, package-selected destination rather than Facebook's authentication service. - **Rationale:** A hard-coded external endpoint receives account credentials through an automatic recovery path. The absence of an install hook does not mitigate this concrete runtime credential-exfiltration behavior. - **Files touched:** fca-config.json - **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 block:** The default configuration enables automatic login and sets an unrelated external API server., The login helper constructs a request body containing the supplied email, password, and optional two-factor secret for that server., The helper sends that credential body with an HTTP POST request., After repeated authentication failures, the MQTT path reads project configuration and invokes the automatic login routine. - **Evidence against:** The manifest contains no preinstall, install, or postinstall lifecycle hook., Remote-control WebSocket support is disabled by default. ## Affected versions and remediation This report applies to @eryxenx/fca@1.0.5. - Avoid installing @eryxenx/fca@1.0.5. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
