No install-time hook or credential-exfiltration endpoint was confirmed. - **Trigger:** Calling the exported login API - **Impact:** Modifies the consuming project and may execute lifecycle code from the newly installed dependency graph. - **Evidence paths:** index.js, checkUpdate.js, package.json, e2ee.js, lib/index.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-23T09:20:28.972Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic self-update through execSync npm install - **Rationale:** The automatic package-manager invocation and consumer-manifest mutation are concrete risky behavior, but they are limited to hridoy-fca's own registry package and occur at runtime rather than installation. This supports a warning rather than a malicious block. - **Files touched:** package.json - **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:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** login automatically starts update checking, newer registry version is installed via shell npm command, consumer package.json is rewritten after update - **Evidence against:** no npm lifecycle hook is declared, update targets this package's npm registry entry, E2EE native loading is gated by enableE2EE ## Public findings ### 1.
