If the registry reports a newer version, the package invokes npm install in the consumer project without confirmation; the E2EE component also loads shipped native binaries. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-08-23T09:11:55.587Z - **Finished:** 2026-08-23T09:13:31.458Z - **Download time:** 511 ms - **Static scan time:** 1355 ms - **AI review time:** 94003 ms - **Total time:** 95871 ms ## Security analysis ### Published attack-surface review - **Summary:** A normal login triggers an automatic self-update check. If the registry reports a newer version, the package invokes npm install in the consumer project without confirmation; the E2EE component also loads shipped native binaries. - **Trigger:** Consumer calls the exported login API. - **Impact:** A compromised or malicious newer registry release can execute through npm in the consumer project and alter its dependency manifest. - **Evidence paths:** index.js, checkUpdate.js, lib/index.mjs, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-23T09:13:31.458Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Unprompted registry-driven npm self-update and native-library loading. - **Rationale:** The package has no install lifecycle hook or confirmed exfiltration, so source does not establish malicious intent. Its unprompted runtime self-update and opaque native execution are concrete supply-chain risks that warrant a warning. - **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:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Medium - **Evidence for:** login() automatically starts the updater once per process., Updater fetches the registry latest version, then runs npm install in the consumer project., E2EE path loads shipped stripped native libraries through koffi. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., Updater is fixed to hridoy-fca and its documented purpose is self-updating., Readable network use is primarily Facebook API/Messenger functionality; no credential exfiltration endpoint was found. ## Public findings ### 1.
