No install lifecycle hook is present. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 88.0% - **Started:** 2026-08-23T08:52:48.452Z - **Finished:** 2026-08-23T08:54:45.697Z - **Download time:** 764 ms - **Static scan time:** 1359 ms - **AI review time:** 115120 ms - **Total time:** 117245 ms ## Security analysis ### Published attack-surface review - **Summary:** A successful login silently checks for updates and, if newer, installs hridoy-fca into the caller's project and rewrites its manifest. No install lifecycle hook is present. - **Trigger:** Application calls the exported login function. - **Impact:** Changes the consuming project's dependency state and executes npm during application runtime. - **Evidence paths:** package.json, index.js, checkUpdate.js, lib/index.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-23T08:54:45.697Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** runtime self-update via npm install and package.json rewrite - **Rationale:** Source confirms a package-aligned but silent runtime self-updater that mutates the consumer project, plus native-code loading. There is no confirmed credential exfiltration, unrelated endpoint, or install-time malicious chain. - **Files touched:** package.json, checkUpdate.js, index.js, lib/index.mjs, 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:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** Calling login triggers an update check that can run npm install in the host project., The updater rewrites the host project's package.json dependency version., E2EE code loads a shipped native library through koffi. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., Update endpoints target this package's npm registry record and its GitHub changelog., The import-time update check is gated by HRIDOY\_FCA\_AUTO\_UPDATE\_CHECK=1. ## Public findings ### 1.
