Enabling E2EE loads opaque native code, and explicit update helpers can modify the caller project. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 87.0% - **Started:** 2026-08-26T19:47:57.966Z - **Finished:** 2026-08-26T19:50:15.446Z - **Download time:** 514 ms - **Static scan time:** 1268 ms - **AI review time:** 135696 ms - **Total time:** 137480 ms ## Security analysis ### Published attack-surface review - **Summary:** No confirmed malicious chain was found in the reviewed JavaScript. Enabling E2EE loads opaque native code, and explicit update helpers can modify the caller project. - **Trigger:** Importing the package performs a remote update check; enabling E2EE loads the native library; calling updateNpmPackage or updateUserPackageJson modifies the caller project. - **Impact:** The opaque native library has unverified behavior, while an application that passes untrusted input to the update helper could invoke a shell command or rewrite its package.json. - **Evidence paths:** package.json, index.js, checkUpdate.js, lib/index.mjs, e2ee.js - **Review source:** ai\_review - **Reviewed:** 2026-08-26T19:50:15.446Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Background update metadata fetch, optional native-library loading, and explicit project update helpers. - **Rationale:** The source does not show install-time execution, credential exfiltration to an unrelated endpoint, or automatic project mutation. The bundled native libraries and shell-based update helper leave a real unresolved security risk. - **Files touched:** build/messagix.so, build/messagix.dll, package.json - **Network endpoints:** https://registry.npmjs.org/hridoy-fca/latest, https://raw.githubusercontent.com/hridoy-dev/HRIDOY-FCA/main/CHANGELOG.md, https://www.facebook.com/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** The main entry point starts an update check when the package is imported., The exported update helper runs npm through a shell and can rewrite the caller's package.json., Optional E2EE support loads bundled opaque native libraries through koffi. - **Evidence against:** package.json has no install or lifecycle hook., The automatic update check only fetches version and changelog data, then prints an install command., The native library is reached only when E2EE is enabled., Reviewed JavaScript sends authentication data to Facebook-related service endpoints for its stated chat-client purpose; no separate exfiltration endpoint was found. ## Public findings ### 1.
