That payload dynamically evaluates fetched code. - **Trigger:** npm install, before the package is imported - **Impact:** Arbitrary code execution in the installing user's environment, enabling follow-on credential theft or persistence. - **Evidence paths:** package.json, setup.mjs, math\_init.js, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T12:00:55.795Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time remote binary execution and fetched-code eval - **Attack narrative:** The preinstall hook runs setup.mjs, which downloads and executes Bun if absent, then uses it to run the obfuscated math\_init.js. The payload contains a network response-to-eval path, allowing remotely supplied code to execute during installation. - **Rationale:** The lifecycle hook is unrelated to an API client and creates a concrete install-time remote-code-execution chain. The generated client in dist does not justify this payload. - **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 runs \`node setup.mjs\` in preinstall., setup.mjs downloads and executes a Bun binary during installation., setup.mjs executes obfuscated math\_init.js., math\_init.js fetches a response body and passes decoded content to eval()., math\_init.js imports child\_process, fs, crypto, http, and https. - **Evidence against:** dist/ is a conventional generated MoneyOut API client., No malicious behavior appears in the dist entrypoint. ## Public findings ### 1.
