Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Source inspection found no lifecycle execution, credential harvesting, exfiltration endpoint, payload execution, or destructive behavior. Static signals stem from Messenger/E2EE functionality and vendored protocol code; the optional remote channel is off by default and only emits received events. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-08-22T06:35:36.593Z - **Finished:** 2026-08-22T06:37:53.035Z - **Download time:** 503 ms - **Static scan time:** 3898 ms - **AI review time:** 132040 ms - **Total time:** 136442 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** No confirmed malicious attack surface. Networking and local session storage are activated through the Messenger API or explicit configuration. - **Trigger:** Caller invokes login/E2EE APIs or explicitly enables remoteControl in fca-config.json. - **Impact:** Expected Messenger session and messaging operations; no unconsented install-time behavior found. - **Evidence paths:** package.json, module/config.js, module/loginHelper.js, src/remote/remoteClient.js, src/api/socket/e2ee/store.js - **Review source:** ai\_review - **Reviewed:** 2026-08-22T06:37:53.035Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Facebook Messenger API client with optional operator-configured WebSocket events. - **Rationale:** Source inspection found no lifecycle execution, credential harvesting, exfiltration endpoint, payload execution, or destructive behavior. Static signals stem from Messenger/E2EE functionality and vendored protocol code; the optional remote channel is off by default and only emits received events. - **Files touched:** fca-config.json, fcanx\_e2ee\_\.json - **Network endpoints:** https://www.facebook.com/ ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** No install lifecycle hook is declared., Remote control is disabled by default and requires operator configuration., Configured remote messages are emitted as events; no command execution is present. - **Evidence against:** Entrypoint exposes a Messenger login API and performs user-invoked Facebook networking., E2EE code persists local encrypted session material when its API is used. ## Affected versions and remediation This report applies to fca-nx@1.9.0. - Review the evidence and your use of fca-nx@1.9.0 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
