It installs nx-fca into the consuming project and can alter that project's dependency manifest. - **Trigger:** Runtime import/require of index.js. - **Impact:** Unconsented installation of a different remote package; its install scripts and code enter the caller project. - **Evidence paths:** index.js, checkUpdate.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-26T07:17:58.767Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time registry lookup followed by child-process npm install and manifest rewrite. - **Attack narrative:** When a consumer imports fca-nx, index.js silently invokes checkForFCAUpdate. The checker queries the npm registry for nx-fca, a different package name, then executes npm install nx-fca@\ --save in the consumer's working directory and may rewrite that project's package.json. This is an unconsented remote dependency installation chain activated by import. - **Rationale:** The package performs a concealed import-time installation of a differently named package into the consuming project, controlled by a remote registry response. No lifecycle hook is needed for this concrete supply-chain attack surface. - **Files touched:** index.js, checkUpdate.js, package.json, node\_modules/nx-fca/package.json, process.cwd()/package.json - **Network endpoints:** https://registry.npmjs.org/nx-fca/latest ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Importing index.js automatically starts an update check., Updater targets foreign package nx-fca although this package is fca-nx., Remote version result drives npm install in the caller's working directory., Updater rewrites the caller project's package.json dependency. - **Evidence against:** package.json has no npm lifecycle hook., Facebook and image-upload requests otherwise match advertised chat API features. ## Public findings ### 1.
