Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 21 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:** 10.8.0 - **Selected version is latest:** Yes - **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. Required high-severity paths are Facebook-aligned Messenger API code, and package.json has no install lifecycle. Scanner malware-similarity and cookie-exfil labels are noisy leftovers from this FCA fork’s product surface, not a live attack chain. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 84.0% - **Started:** 2026-09-18T15:18:45.002Z - **Finished:** 2026-09-18T15:23:48.578Z - **Download time:** 508 ms - **Static scan time:** 1378 ms - **AI review time:** 301689 ms - **Total time:** 303576 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:** This is an unofficial Facebook Messenger client. Network calls go to Facebook and Messenger hosts, install scripts do not run extra code, and optional third-party login or remote control stay off unless the operator configures them. No confirmed covert harvest or exfil path remains in this release. - **Trigger:** A consumer calls login() or other documented API methods after install. - **Impact:** No confirmed malicious impact in this package snapshot. - **Review source:** ai\_review - **Reviewed:** 2026-09-18T15:23:48.578Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Unofficial Messenger session and GraphQL client - **Rationale:** Required high-severity paths are Facebook-aligned Messenger API code, and package.json has no install lifecycle. Scanner malware-similarity and cookie-exfil labels are noisy leftovers from this FCA fork’s product surface, not a live attack chain. ### Review decision - **Verdict:** Clean - **Confidence:** 84.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for AI clean decision:** package.json has no preinstall, install, or postinstall hooks; only test and lint scripts., e2ee/vendor/fb-e2ee.cjs sends session cookies to Facebook E2EE registration at reg-e2ee.facebook.com, not a package-controlled receiver., src/api/messaging/story.js posts story replies to Facebook GraphQL., src/api/action/getAccess.js reads access tokens from business.facebook.com after two-factor reauth., src/api/messaging/notes.js creates and reads Messenger notes through Facebook GraphQL., src/api/threads/getThreadInfo.js and src/api/messaging/uploadAttachment.js call Facebook graphqlbatch and mercury upload endpoints. - **Evidence against:** Scanner similarity hits match ordinary unofficial Messenger API methods, not a remaining steal/exfil payload., loginViaAPI can POST email and password only when the operator sets apiServer; the default is empty and the code refuses a silent third-party sink., Remote control is off by default with an empty URL; auto-update is a no-op stub., User-callable httpGet/httpPost use a domain-scoped cookie jar rather than copying Facebook cookies onto arbitrary hosts. ## Affected versions and remediation This report applies to shadowx-fca@10.8.0. - Review the evidence and your use of shadowx-fca@10.8.0 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.
