Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 18 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 10.5.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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. The scanner signals map to normal Messenger/E2EE functionality, fixed local loading, and opt-in features. Source inspection found no lifecycle execution, command execution, stealth persistence, or concrete data exfiltration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 92.0% - **Started:** 2026-08-26T07:46:36.574Z - **Finished:** 2026-08-26T07:48:09.572Z - **Download time:** 506 ms - **Static scan time:** 3649 ms - **AI review time:** 88842 ms - **Total time:** 92998 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 was established. User-invoked login connects to Facebook; optional external-login and remote-control paths require explicit configuration. - **Trigger:** Application imports and calls login with user-supplied credentials or session state. - **Impact:** Expected Messenger session/network operations; no unconsented install-time action or exfiltration endpoint found. - **Evidence paths:** package.json, module/config.js, module/loginHelper.js, src/utils/versionCheck.js, src/api/socket/e2ee/index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-26T07:48:09.572Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Facebook API client with opt-in external endpoint and E2EE session storage. - **Rationale:** The scanner signals map to normal Messenger/E2EE functionality, fixed local loading, and opt-in features. Source inspection found no lifecycle execution, command execution, stealth persistence, or concrete data exfiltration. - **Files touched:** src/api/socket/e2ee/index.js, .shadowx/e2ee\_device.json - **Network endpoints:** https://www.facebook.com, https://registry.npmjs.org/shadowx-fca/latest ### Review decision - **Verdict:** Clean - **Confidence:** 92.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** No npm lifecycle hook is declared., External credential submission requires a configured apiServer., Remote WebSocket control is disabled by default., Runtime network calls target Facebook and npm registry endpoints. - **Evidence against:** No child-process, shell, payload-download, or broad file-harvesting code found., The dynamic import targets a fixed package-local lib path., E2EE state persistence is package-specific session storage after user login. ## Affected versions and remediation This report applies to shadowx-fca@10.5.0. - Review the evidence and your use of shadowx-fca@10.5.0 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.
