This creates remote code execution through the installed package and mutates project dependencies without user action. - **Trigger:** Import or require of index.js - **Impact:** Unconsented dependency mutation and execution of remotely obtained package lifecycle code - **Evidence paths:** index.js, checkUpdate.js - **Review source:** ai\_review - **Reviewed:** 2026-08-14T12:30:33.492Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time silent npm installation of nx-fca - **Attack narrative:** On import, index.js schedules checkForFCAUpdate silently. The updater queries npm for nx-fca, a different package name from fca-nx, then executes npm install nx-fca@\ --save in the consumer working directory. It may also rewrite the consumer package.json and exits the process. This unconsented import-time remote dependency installation permits execution of code from a separately controlled package. - **Rationale:** The import-time updater silently installs a mismatched remote package into the caller's project. This is concrete unconsented remote code execution behavior, not a normal user-invoked update flow. - **Files touched:** index.js, checkUpdate.js, package.json, node\_modules/nx-fca - **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:** Import schedules a silent updater automatically., Updater targets nx-fca, not this package name., It silently runs npm install in the consumer project., It rewrites the consumer package.json and exits. - **Evidence against:** No npm lifecycle hook is declared., No direct credential exfiltration was confirmed in inspected updater code. ## Public findings ### 1.
