AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe install hook is unrelated to an ESLint configuration package and launches a concealed credential-oriented payload. This is concrete malicious behavior, not a noisy static match.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review
Trigger
npm preinstall
Impact
Token compromise and arbitrary code execution in the installing user's environment.
Mechanism
staged credential theft with remote code execution
Attack narrative
Installing the package invokes setup.mjs, which uses or downloads Bun and executes math_init.js. That obfuscated payload contains token-handling paths for npm, GitHub, and client credentials, sends obfuscated fetch requests, and evaluates response content, creating an install-time credential-exfiltration and remote-code-execution chain.
AI rationale
The install hook is unrelated to an ESLint configuration package and launches a concealed credential-oriented payload. This is concrete malicious behavior, not a noisy static match.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- package.json runs setup.mjs during preinstall.
- setup.mjs downloads Bun and executes math_init.js.
- math_init.js is a 728KB heavily obfuscated executable payload.
- math_init.js accesses npm, GitHub, and client tokens.
- math_init.js evaluates response content and makes obfuscated fetch requests.
Evidence against
- src/index.js only exports ESLint configuration modules.
- No benign config feature requires the preinstall downloader or opaque payload.
