E2EE activation also loads an opaque native binary. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 86.0% - **Started:** 2026-08-23T09:01:02.074Z - **Finished:** 2026-08-23T09:02:02.153Z - **Download time:** 765 ms - **Static scan time:** 1372 ms - **AI review time:** 57940 ms - **Total time:** 60079 ms ## Security analysis ### Published attack-surface review - **Summary:** When an operator sets the auto-update environment flag, importing the library can fetch registry metadata and execute npm install in the current project. E2EE activation also loads an opaque native binary. - **Trigger:** Import with HRIDOY\_FCA\_AUTO\_UPDATE\_CHECK=1; E2EE client use for native loading. - **Impact:** A registry-controlled version string or compromised future package release could cause dependency mutation and package-manager execution in the consumer project. - **Evidence paths:** package.json, index.js, checkUpdate.js, lib/index.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-23T09:02:02.153Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Opt-in self-update plus native binary loading. - **Rationale:** No install hook or confirmed exfiltration proves malicious intent, but the opt-in remote self-updater mutates consumer projects and executes npm, while a shipped native binary remains opaque to source review. - **Files touched:** package.json, node\_modules/hridoy-fca/package.json, build/messagix.so, build/messagix.dll - **Network endpoints:** https://registry.npmjs.org/hridoy-fca/latest, https://raw.githubusercontent.com/hridoy-dev/HRIDOY-FCA/main/CHANGELOG.md ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** Opt-in import-time updater fetches registry metadata, then runs npm install in the consumer project., The updater rewrites the consumer project's package.json dependency version., E2EE code dynamically loads a package-shipped native library through koffi; its binary behavior is not source-auditable here. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., Updater activation requires HRIDOY\_FCA\_AUTO\_UPDATE\_CHECK=1., No source-confirmed credential exfiltration or unrelated remote endpoint was found; Facebook calls implement the stated chat API. ## Public findings ### 1.
