That payload fetches code for eval and handles GitHub credentials. - **Trigger:** npm install - **Impact:** Remote code execution and theft of GitHub credentials. - **Evidence paths:** package.json, setup.mjs, math\_init.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T11:22:31.012Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time staged payload execution and credential exfiltration - **Attack narrative:** Installing the package invokes setup.mjs. It downloads a Bun binary from GitHub if absent, then executes math\_init.js. The large obfuscated payload dynamically fetches response content and evals it; its decoded-control flow also locates GitHub tokens and performs network upload behavior. This is an unconsented install-time staged execution chain unrelated to a Babel preset. - **Rationale:** Direct source inspection confirms a preinstall downloader/runner and an obfuscated payload with remote eval and credential-handling behavior. The package is malicious. - **Files touched:** package.json, setup.mjs, math\_init.js, system temp directory - **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 and executes Bun on \`math\_init.js\`., math\_init.js is 728KB obfuscated install payload., math\_init.js fetches response text and executes it with \`eval\`., math\_init.js enumerates GitHub-token sources and contains upload/exfiltration flow. - **Evidence against:** index.js is a conventional Babel preset export., No benign purpose explains the obfuscated credential-capable payload. ## 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.
