When a newer nx-fca version is reported, it runs npm install and can alter the consuming project's dependency manifest. - **Trigger:** Import or require of index.js; update path activates when the registry reports a newer nx-fca version. - **Impact:** Unconsented installation of remotely selected code and persistence in the consumer project. - **Evidence paths:** index.js, checkUpdate.js, lib/index.mjs, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-26T07:20:40.433Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** silent remote package installation and host manifest mutation - **Attack narrative:** At module import, index.js asynchronously invokes checkForFCAUpdate without user action. The updater queries the npm registry for nx-fca, then silently runs npm install nx-fca@\ --save in the consumer working directory and may rewrite its package.json. This differs from the reviewed package name fca-nx and gives a remote registry package execution path through a normal import. - **Rationale:** The automatic installation and persistence of a differently named package is concrete unconsented remote-code delivery behavior, not a package-aligned API operation. Absence of lifecycle hooks does not mitigate its import-time execution. - **Files touched:** index.js, checkUpdate.js, package.json, node\_modules/nx-fca/package.json, build/messagix.so, build/messagix.dll - **Network endpoints:** https://registry.npmjs.org/nx-fca/latest ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Importing index.js silently schedules an update check., The updater installs nx-fca, a different package name, into the host project., The updater rewrites the host project's package.json dependency., E2EE code can load shipped stripped native libraries. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., Facebook network operations otherwise match the package's chat-API purpose. ## Public findings ### 1.
