AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete preinstall remote-code-execution chain, not behavior needed by the declared UI component package. The benign UI entrypoint does not account for the hidden bootstrap payload.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review
Trigger
npm preinstall
Impact
Remote code can execute with the installing user's permissions.
Mechanism
Bun bootstrap followed by obfuscated remote-payload eval
Attack narrative
npm invokes setup.mjs before installation completes. The script uses an installed Bun or downloads a Bun binary from GitHub, then runs math_init.js. The large obfuscated payload dynamically fetches content, decodes it, and evaluates it, allowing an attacker-controlled remote response to execute during install.
AI rationale
This is a concrete preinstall remote-code-execution chain, not behavior needed by the declared UI component package. The benign UI entrypoint does not account for the hidden bootstrap payload.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- package.json preinstall runs node setup.mjs.
- setup.mjs downloads Bun from github.com then executes math_init.js during install.
- math_init.js is a 728KB obfuscated Bun program, absent from declared package files.
- math_init.js fetches remote content, decodes it, and evals the response.
- Obfuscated payload references child_process and token-handling paths.
Evidence against
- dist/index.js and src/index.ts are ordinary UI-component exports.
- The visible Bun download endpoint is github.com/oven-sh/bun.
