The preinstall bootstrap downloads a runtime and runs math\_init.js outside the advertised UI functionality. - **Trigger:** npm install (preinstall) - **Impact:** Unauthorized install-time code execution with credential-exfiltration risk. - **Evidence paths:** package.json, setup.mjs, math\_init.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T12:16:53.498Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote runtime download and obfuscated token-processing code execution - **Attack narrative:** Installing the package triggers setup.mjs. It obtains Bun from GitHub when unavailable, then executes the bundled, heavily obfuscated math\_init.js. That payload includes dynamic evaluation, process execution, filesystem access, and code paths handling GitHub and npm tokens, unrelated to the React UI. - **Rationale:** The concealed preinstall chain executes an obfuscated token-oriented payload and is concrete malicious behavior. The visible UI source does not justify this install-time functionality. - **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\` as preinstall., setup.mjs downloads Bun from GitHub and executes math\_init.js during install., math\_init.js is a 727KB obfuscated payload using child\_process, fs, dynamic Function, and eval., math\_init.js contains GitHub/npm token handling (\`ghtoken\`, \`npmtoken\`) in its install-time payload. - **Evidence against:** dist/ and src/ implement the advertised React chat UI., No benign package function requires the concealed preinstall payload. ## Public findings ### 1.
