The payload includes remote-response eval and token-related logic. - **Trigger:** npm preinstall - **Impact:** Arbitrary install-time code execution and potential credential theft. - **Evidence paths:** package.json, setup.mjs, math\_init.js, index.js, degraded-support.js, full-support.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T11:39:15.506Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** downloads/executes Bun to run obfuscated code with remote eval - **Attack narrative:** On npm preinstall, setup.mjs obtains Bun if absent, then runs math\_init.js. That large obfuscated payload includes an evaluated remote response and GitHub token handling, creating an install-time arbitrary-code and credential-risk chain unrelated to a browserslist configuration package. - **Rationale:** Direct source inspection confirms an unconsented preinstall bootstrap into an obfuscated payload with remote eval. This is concrete malicious behavior, not a package-aligned dependency setup. - **Files touched:** 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 preinstall runs setup.mjs., setup.mjs downloads Bun and executes math\_init.js during install., math\_init.js is a 728KB obfuscated payload., math\_init.js fetches response content and evals it., math\_init.js contains GitHub-token handling paths (ghtoken, ghs\_old, ghs\_jwt). - **Evidence against:** Normal entrypoints only export static browserslist arrays., No benign package function requires an install-time runtime bootstrap or opaque payload. ## Public findings ### 1.
