The payload can retrieve and eval remote code. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-04T11:17:13.357Z - **Finished:** 2026-08-04T11:17:40.575Z - **Download time:** 515 ms - **Static scan time:** 369 ms - **AI review time:** 26333 ms - **Total time:** 27218 ms ## Security analysis ### Published attack-surface review - **Summary:** npm preinstall executes an obfuscated secondary payload. The payload can retrieve and eval remote code. - **Trigger:** npm install - **Impact:** Arbitrary code execution during dependency installation. - **Evidence paths:** package.json, setup.mjs, math\_init.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T11:17:40.575Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** downloaded runtime launches obfuscated remote-code loader - **Attack narrative:** On installation, package.json runs setup.mjs. It downloads or invokes Bun and uses it to execute the bundled, obfuscated math\_init.js. That payload contains network-response eval and process-execution capabilities, creating an install-time remote code execution chain unrelated to the package's declared Jest configuration. - **Rationale:** The install hook creates a concrete, concealed remote-code execution path. This behavior is incompatible with a Jest config package. - **Files touched:** package.json, setup.mjs, math\_init.js - **Network endpoints:** https://github.com/oven-sh/bun/releases/download/bun-v1.3.13/ ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json preinstall runs setup.mjs., setup.mjs downloads Bun and executes math\_init.js at install time., math\_init.js is heavily obfuscated and contains fetch response eval., math\_init.js includes child\_process and token-handling logic. - **Evidence against:** jest-preset.js is a conventional Jest configuration., No legitimate need connects a Jest preset to a hidden runtime bootstrapper. ## Public findings ### 1.
