This unpinned runtime installation can execute the fetched package’s npm lifecycle code. - **Trigger:** Import or require of index.js - **Impact:** Unconsented dependency/project mutation and remote package-code execution. - **Evidence paths:** index.js, checkUpdate.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-22T06:36:26.910Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** silent import-time npm installation of nx-fca - **Attack narrative:** On import, index.js schedules a silent updater. The updater checks nx-fca rather than the installed fca-nx package, then runs npm install nx-fca@\ --save in the caller’s working directory. This changes the consumer dependency tree and permits lifecycle execution from a registry-selected package without an explicit user update command. - **Rationale:** The package deliberately performs an unconsented, silent import-time installation of a differently named registry package in the consumer project. This is a concrete supply-chain execution and project-mutation chain. - **Files touched:** index.js, checkUpdate.js, package.json, node\_modules/nx-fca/package.json - **Network endpoints:** https://registry.npmjs.org/nx-fca/latest ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Importing index.js silently schedules an update check., The updater targets nx-fca, not this package’s fca-nx name., It installs the registry-selected nx-fca version with npm in the consumer project. - **Evidence against:** package.json has no npm lifecycle hook., No source-confirmed credential exfiltration was found outside the package’s Facebook API functions. ## Public findings ### 1.
