No source-confirmed third-party exfiltration or install-time execution was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 84.0% - **Started:** 2026-08-14T05:07:58.158Z - **Finished:** 2026-08-14T05:10:08.764Z - **Download time:** 760 ms - **Static scan time:** 1354 ms - **AI review time:** 128491 ms - **Total time:** 130606 ms ## Security analysis ### Published attack-surface review - **Summary:** When E2EE is enabled and connected, the package loads an opaque native library with Facebook session cookies. No source-confirmed third-party exfiltration or install-time execution was found. - **Trigger:** Consumer enables E2EE and calls connectE2EE. - **Impact:** Unverifiable native code could access authenticated Messenger session data. - **Evidence paths:** package.json, index.js, e2ee.js, lib/index.mjs, build/messagix.so - **Review source:** ai\_review - **Reviewed:** 2026-08-14T05:10:08.764Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Native E2EE client loading with authenticated cookies. - **Rationale:** No concrete malicious chain is proven, but an opaque native component receives high-value session cookies and performs networked messaging operations. This is an unresolved dangerous capability warranting a warning. - **Files touched:** build/messagix.so, lib/index.mjs, e2ee.js - **Network endpoints:** https://b-graph.facebook.com/graphql ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** Loads bundled native binary through koffi., E2EE bridge passes Facebook session cookies to native client., Native binary is opaque and has broad messaging/E2EE capability. - **Evidence against:** No preinstall, install, or postinstall hook., Main entry exports a login function; it does not auto-run., Reviewed JS network calls are Facebook or user-configured image hosts; no confirmed exfiltration endpoint. ## Public findings ### 1.
