Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Installing the package automatically modifies the consumer project's AI-agent MCP configuration. The same lifecycle hook overwrites installed dependency files and can run another dependency's installer. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-13T22:20:19.576Z - **Finished:** 2026-09-13T22:21:30.863Z - **Download time:** 761 ms - **Static scan time:** 7494 ms - **AI review time:** 63031 ms - **Total time:** 71287 ms The recorded confidence comes from the underlying analysis.

The same lifecycle hook overwrites installed dependency files and can run another dependency's installer. - **Trigger:** npm installation of basinfy as a project dependency - **Impact:** AI-agent behavior in the project can be changed without an explicit setup command; dependency code can be replaced and a nested installer runs with the install environment. - **Evidence paths:** package.json, scripts/postinstall.js, bin/native-resolve.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T22:21:30.863Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall MCP registration, dependency replacement, and nested installer execution - **Attack narrative:** On npm install, the lifecycle hook selects the invoking project, detects agents, and silently installs Basinfy MCP configuration. It also deletes and recreates dependency directories, patches a transformer dependency, and invokes the onnxruntime installer if a native binding is absent. These automatic mutations and nested execution occur before the user runs an explicit Basinfy setup command. - **Rationale:** The automatic postinstall hook mutates a foreign AI-agent control surface and installed dependencies, then can execute another install script with inherited environment variables. This is concrete install-hook abuse rather than user-invoked configuration. - **Files touched:** scripts/postinstall.js, bin/native-resolve.js, node\_modules/sharp/, node\_modules/onnxruntime-web/, node\_modules/onnxruntime-node/script/install.js, consumer-project AI-agent MCP configuration ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package runs a postinstall script automatically., Postinstall silently configures MCP for detected agents in the consumer project., Postinstall replaces dependency directories and files., It executes a dependency install script with inherited environment variables. - **Evidence against:** Global installs exit before MCP configuration., The MCP setup can be disabled with environment variables. ## Affected versions and remediation This report applies to basinfy@1.1.0. - Avoid installing basinfy@1.1.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
