## Security analysis

### Published attack-surface review

- **Summary:** npm installation executes an obfuscated second-stage payload. The payload includes remote-code evaluation and GitHub credential-token handling.

- **Trigger:** npm preinstall

- **Impact:** Arbitrary code execution and potential credential theft during installation.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-04T11:53:21.370Z

### AI review details

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

- **Mechanism:** downloads Bun, executes obfuscated payload, fetches and evals remote content

- **Attack narrative:** The preinstall hook invokes setup.mjs, which downloads or locates Bun and executes math\_init.js. That opaque payload contains child-process use, GitHub token-related handling, and evaluates text returned from a network request, enabling a remotely controlled malicious stage during dependency installation.

- **Rationale:** This is concrete unconsented install-time remote payload execution, not functionality aligned with a React SDK.

- **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\` at preinstall., setup.mjs downloads Bun from github.com then executes \`math\_init.js\`., math\_init.js is a 728KB obfuscated Bun payload., math\_init.js fetches response text and passes it to \`eval\`., math\_init.js references child\_process and GitHub token fields ghtoken/ghs\_old/ghs\_jwt.

- **Evidence against:** Published React entrypoint dist/index.js only re-exports components., No benign package function requires an obfuscated install-time Bun payload.
