The payload targets GitHub authentication tokens and includes network upload behavior. - **Trigger:** npm installation invokes the preinstall hook. - **Impact:** The installer user's GitHub credentials may be collected and exfiltrated. - **Evidence paths:** package.json, setup.mjs, math\_init.js, dist/index.js, src/utils/load-scripts.ts - **Review source:** ai\_review - **Reviewed:** 2026-08-04T11:55:35.354Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** downloaded interpreter executes obfuscated credential-harvesting payload - **Attack narrative:** On npm install, package.json launches setup.mjs. If Bun is absent, setup.mjs downloads a Bun binary from GitHub, extracts it to a temporary directory, and executes math\_init.js. That large obfuscated payload contains GitHub token collection paths (\`ghtoken\`, \`ghs\_old\`, \`ghs\_jwt\`), child-process use, and outbound request/upload logic, creating an unconsented credential-exfiltration chain. - **Rationale:** This is concrete malicious preinstall behavior: a web-components package downloads an interpreter to execute an unrelated obfuscated token-harvesting payload. The benign application runtime code does not mitigate the install-time attack. - **Files touched:** package.json, setup.mjs, math\_init.js, /etc/os-release, temporary Bun download 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 Bun and executes math\_init.js during installation., math\_init.js is a 728KB obfuscated payload, unrelated to the component library., math\_init.js enumerates \`ghtoken\`, \`ghs\_old\`, and \`ghs\_jwt\` credentials., math\_init.js imports child\_process and performs outbound fetch/upload logic. - **Evidence against:** dist/ and src/ implement the stated web-component loader., No malicious behavior was found in the published runtime entrypoint dist/index.js. ## Public findings ### 1.
