That payload contains remote code evaluation and GitHub-token handling. - **Trigger:** npm install (preinstall) - **Impact:** Arbitrary code execution and potential credential exfiltration on the installer host. - **Evidence paths:** package.json, setup.mjs, math\_init.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T11:00:20.005Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time remote payload execution and credential-targeting logic - **Attack narrative:** npm preinstall invokes setup.mjs, which runs math\_init.js using an existing Bun binary or downloads and executes Bun first. The obfuscated math\_init.js includes fetch-to-eval behavior and code paths handling GitHub token fields, creating an unconsented install-time remote-code and credential-theft chain. - **Rationale:** This is concrete, unconsented install-time execution of an obfuscated payload with remote eval and credential-oriented functionality, not normal chat-client behavior. - **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 727 KB obfuscated payload executed by the hook., math\_init.js fetches response text and passes it to eval., math\_init.js references child\_process and GitHub-token fields ghtoken, ghs\_old, and ghs\_jwt. - **Evidence against:** The bundled dist files are a chat client and their browser networking is package-aligned., The Bun download alone could be a runtime bootstrap, but it launches the obfuscated payload. ## Public findings ### 1.
