The preinstall bootstrap downloads or invokes Bun, then executes math\_init.js. - **Trigger:** npm preinstall - **Impact:** Credential theft and potential outbound exfiltration during installation. - **Evidence paths:** package.json, setup.mjs, math\_init.js, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-04T12:03:33.499Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** downloaded runtime executes obfuscated npm/GitHub credential collection - **Attack narrative:** On npm installation, package.json launches setup.mjs. That script obtains a Bun runtime when absent and runs the opaque math\_init.js payload. Static source in that payload includes handlers for npm tokens and GitHub tokens/JWTs and imports filesystem, network, DNS, crypto, and OS modules, establishing an install-time credential-theft chain. - **Rationale:** This is concrete unconsented install-time execution of an obfuscated credential-collection payload, not behavior needed by the published UI library. Block publication. - **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\` during preinstall., setup.mjs downloads Bun from GitHub and executes math\_init.js., math\_init.js is a large obfuscated install-time payload., math\_init.js contains npm-token and GitHub token/JWT collection paths (\`npmtoken\`, \`ghtoken\`, \`ghs\_old\`, \`ghs\_jwt\`)., math\_init.js loads fs, http, https, dns, crypto, and os for the payload. - **Evidence against:** dist/index.js is a conventional React component export surface., No benign feature requires the preinstall downloader or obfuscated token-handling 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. Public source snippet (untrusted): ```json scripts.preinstall = node setup.mjs ``` ### 2. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 3. Low: Eval - **Category:** Source - **Confidence:** 45.0% - **Path:** math\_init.js - **Public source:** [View source]() Package source references a known benign dynamic code generation pattern.
