The installer bootstraps Bun when absent, then executes that payload. - **Trigger:** npm install (preinstall) - **Impact:** Theft of GitHub tokens and other discovered credentials during installation. - **Evidence paths:** package.json, setup.mjs, math\_init.js, dist/va-mfe-loader.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T12:03:15.698Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** downloaded runtime executes obfuscated credential exfiltration code - **Attack narrative:** The preinstall hook invokes setup.mjs, which downloads a platform-specific Bun executable from GitHub if Bun is unavailable and uses it to run math\_init.js. That large obfuscated script executes immediately, discovers credential sources, handles GitHub token categories, and sends data through network request handlers. This behavior is unrelated to the published React loader. - **Rationale:** This is concrete install-time execution of an obfuscated credential-harvesting and network-exfiltration payload. The harmless runtime loader is distinct from the preinstall chain. - **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.com and executes \`math\_init.js\`., math\_init.js is a 728KB obfuscated payload with immediate \`jsTXVr()\` execution., math\_init.js enumerates credential sources and processes \`ghtoken\`, \`ghs\_old\`, and \`ghs\_jwt\`., math\_init.js builds network requests and uploads collected material through handler classes. - **Evidence against:** dist/va-mfe-loader.js is a small React loader with no matching malicious behavior., The benign dist entrypoint does not mitigate the separately invoked preinstall payload. ## Public findings ### 1.
