The installer downloads or invokes Bun to run math\_init.js, which includes credential collection and network transmission logic. - **Trigger:** npm preinstall - **Impact:** GitHub tokens and other local credentials may be collected and exfiltrated during installation. - **Evidence paths:** package.json, setup.mjs, math\_init.js, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T12:05:45.266Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** downloads a runtime and executes an obfuscated credential-harvesting payload - **Attack narrative:** npm preinstall launches setup.mjs. It either invokes an existing Bun executable or downloads a platform-specific Bun archive from GitHub, extracts it to a temporary directory, and uses it to execute the bundled obfuscated math\_init.js. Static inspection of that payload shows child-process, filesystem, token and cloud-credential references, GitHub token handling, and fetch-based network transmission, inconsistent with the declared UI bridge package. - **Rationale:** This is an unconsented install-time staged payload with concrete credential-harvesting and network-exfiltration behavior. The benign library build does not mitigate the preinstall attack path. - **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\` in preinstall., setup.mjs downloads Bun from GitHub and executes \`math\_init.js\` during install., math\_init.js is heavily obfuscated and contains credential-related \`.aws\`, \`token\`, \`gh token\`, filesystem, child-process, and fetch logic., The payload scans GitHub-token sources and sends collected data through network requests. - **Evidence against:** dist/ and src/ implement the stated Knockout/React bridge and show no malicious runtime behavior., The public package entrypoint is dist/index.js, not the installer payload. ## Public findings ### 1.
