It writes a virtual environment under the user's home directory before any explicit Jait command is invoked. - **Trigger:** npm installation of the package - **Impact:** Installing this npm package also causes code from a separate Python package supply chain to be installed and executed in a home-directory virtual environment. - **Evidence paths:** package.json, bin/install-runtime.mjs, dist/services/code-graph/graphify-runtime.js - **Review source:** ai\_review - **Reviewed:** 2026-08-31T15:08:01.155Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall pip provisioning of an external Python package - **Attack narrative:** During npm installation, the postinstall hook imports the runtime manager. If its expected executable is absent, it creates ~/.jait/runtime/graphify/venv and invokes pip to install graphifyy==0.9.30. This silently extends installation into a separate Python package supply chain and can execute that artifact without a user command. - **Rationale:** The package has an automatic install-time hook that installs and executes a separate Python artifact in the user's home directory. That unconsented external payload installation is concrete install-hook abuse, even though the inspected JavaScript does not directly harvest credentials. - **Files touched:** bin/install-runtime.mjs, dist/services/code-graph/graphify-runtime.js, ~/.jait/runtime/graphify/venv, ~/.jait/runtime/graphify/runtime.json ### Review decision - **Verdict:** Malicious - **Confidence:** 95.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Installation automatically runs a runtime provisioner., The provisioner creates a virtual environment under the user's home directory and runs pip to install an external Python package., The downloaded package is named graphifyy, a separate unverified supply-chain artifact. - **Evidence against:** The installer pins the external package to one version., The inspected installer contains no credential collection or direct data upload logic. ## Public findings ### 1.
