## Security analysis

### Published attack-surface review

- **Summary:** npm install automatically executes an obfuscated credential-harvesting payload. The payload can fetch and eval remote code, making behavior remotely changeable.

- **Trigger:** npm preinstall

- **Impact:** Credential theft and arbitrary code execution in the installer's environment.

- **Evidence paths:** package.json, setup.mjs, math\_init.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-04T11:53:20.915Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** installer-launched obfuscated payload with remote eval and credential collection

- **Attack narrative:** On npm install, the preinstall hook runs setup.mjs. It invokes Bun on math\_init.js or downloads a Bun release and executes it. The obfuscated payload dynamically loads system modules, collects credential material including GitHub-token data, contacts remote services, and evals decoded fetched content. This creates unconsented install-time credential-exfiltration and remote-code-execution capability.

- **Rationale:** The preinstall chain is unrelated to a React web SDK and deliberately launches an obfuscated payload. Source inspection confirms credential-oriented collection plus remote eval, which is concrete malicious behavior.

- **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 executes math\_init.js through Bun during install., setup.mjs downloads and executes a Bun binary if absent., math\_init.js is a 728KB obfuscated payload with dynamic module loading., math\_init.js fetches data and evals a decoded response., Payload contains credential-harvesting logic, including GitHub-token handling.

- **Evidence against:** dist/ contains a conventional Verdocs web SDK bundle., The only unobscured setup download is the Bun GitHub release URL.
