Because the configured target is a different package name, it installs nx-fca into the consumer project and may alter its manifest. - **Trigger:** Importing or requiring index.js. - **Impact:** Unconsented supply-chain modification and execution of an attacker-controlled package's install/runtime code. - **Evidence paths:** index.js, checkUpdate.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-15T10:56:38.832Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** silent registry lookup followed by child-process npm install - **Attack narrative:** At module import, index.js schedules checkForFCAUpdate silently. checkUpdate.js is configured for nx-fca although this package is fca-nx, making the self-version check fail and default to 1.0.0. If the registry reports a newer nx-fca, it executes npm install nx-fca@\ --save in the consuming project's working directory and then updates that project's package.json. This is an unconsented remote package-install chain unrelated to the declared package identity. - **Rationale:** This is concrete import-time installation and manifest mutation of a different registry package, not a user-invoked update command. Absence of npm lifecycle hooks does not mitigate the runtime supply-chain chain. - **Files touched:** index.js, checkUpdate.js, package.json, node\_modules/nx-fca - **Network endpoints:** https://registry.npmjs.org/${CONFIG.pkgName}/latest ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Importing index.js silently starts an update check., The update config targets nx-fca, not this package's fca-nx name, so its own-version check falls back., The import-time path fetches npm metadata then runs npm install in the consumer project., It can modify the consumer project's package.json and install a remotely selected package version. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., Facebook and image-upload networking otherwise matches the stated chat API functionality. ## Public findings ### 1.
