This grants remotely published package code execution in the consumer project and changes its dependency manifest. - **Trigger:** Consumer calls the exported login function. - **Impact:** Unpinned remote package replacement, consumer package.json mutation, and process termination. - **Evidence paths:** package.json, index.js, checkUpdate.js, lib/index.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-23T09:19:34.995Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Silent registry-driven npm self-update via child process. - **Rationale:** No install-time hook or unrelated credential-exfiltration chain was confirmed, but ordinary login silently enables remote self-replacement and consumer-project mutation. This is a dangerous runtime capability that should warn rather than block. - **Files touched:** checkUpdate.js, index.js, package.json, lib/index.mjs, 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 ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** Calling the exported login function silently starts an update check., A newer registry version triggers npm install in the consumer project., The updater rewrites the consumer package.json dependency before exiting., The package ships a native E2EE binary loaded through koffi when E2EE is enabled. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., Update behavior is documented, and inspected endpoints are npm/GitHub/Facebook-aligned., No inspected source showed credential exfiltration to an unrelated endpoint. ## Public findings ### 1.
