## Security analysis

### Published attack-surface review

- **Summary:** Installing the package unconditionally executes an obfuscated payload. The payload harvests credentials, communicates remotely, and supports fetched-code evaluation.

- **Trigger:** npm preinstall

- **Impact:** Credential exfiltration and arbitrary code execution during dependency installation.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-04T20:08:30.394Z

### AI review details

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

- **Mechanism:** installer-launched credential-harvesting remote-code payload

- **Attack narrative:** The preinstall hook launches setup.mjs, which executes the bundled obfuscated math\_init.js through Bun, downloading Bun when needed. The payload includes credential-source discovery, GitHub-token handling, outbound request construction, and eval of fetched content, creating an unconsented install-time exfiltration and remote-code-execution chain.

- **Rationale:** This behavior is unrelated to a Babel preset and is activated automatically at install time. The clear launcher-to-obfuscated-payload chain establishes concrete malicious behavior.

- **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\` at preinstall., setup.mjs executes math\_init.js with Bun, downloading Bun from GitHub if absent., math\_init.js is a 728 KB obfuscated payload with an immediate async entrypoint., math\_init.js discovers credential sources including GitHub tokens., math\_init.js sends collected data and dynamically evals remotely fetched content.

- **Evidence against:** index.js is a conventional Babel preset wrapper., The Bun download endpoint in setup.mjs is GitHub's official oven-sh release URL.
