The payload includes dynamic remote-code evaluation and Git credential/token handling. - **Trigger:** npm package installation (preinstall) - **Impact:** Remote code execution and probable credential exfiltration during install. - **Evidence paths:** package.json, setup.mjs, math\_init.js, jest-preset.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-04T20:08:24.308Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Bun bootstrap followed by obfuscated dynamic payload execution - **Attack narrative:** Installing the package invokes setup.mjs before user code. It uses an existing Bun binary or downloads a platform-specific Bun release, then runs the obfuscated math\_init.js. That payload contains fetched-content eval and Git credential/token collection and upload behavior, which is unrelated to the declared deprecated Jest preset. - **Rationale:** Direct inspection confirms an install-time bootstrapper executing an obfuscated credential-oriented remote payload. This is concrete malicious supply-chain behavior, not a legitimate configuration-package function. - **Files touched:** package.json, setup.mjs, math\_init.js, /etc/os-release - **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\` at preinstall., setup.mjs downloads Bun from GitHub and executes \`math\_init.js\`., math\_init.js is heavily obfuscated and dynamically evaluates fetched content., math\_init.js contains Git-token handling and network-upload logic unrelated to a deprecated Jest preset., The public entrypoint only throws a deprecation error, inconsistent with install-time downloader/payload. - **Evidence against:** README and jest-preset.js describe a deprecated Jest configuration package. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts.
