AI Security Review
scanned 3mo ago · by lpm-firewall-aiConcrete install-time remote bootstrap and execution of an obfuscated credential-oriented payload establishes malicious behavior. The normal ESLint entrypoint does not mitigate the preinstall attack.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review
Trigger
Installing the package with npm lifecycle scripts enabled.
Impact
Potential theft or abuse of GitHub/cloud credentials at install time.
Mechanism
preinstall remote runtime bootstrap and obfuscated credential-processing payload execution
Attack narrative
Installation invokes setup.mjs, which downloads a Bun binary from GitHub when Bun is absent and uses it to execute math_init.js. That large obfuscated payload uses dynamic code execution and includes AWS, token, child-process, and GitHub-token handling logic, inconsistent with an ESLint plugin.
AI rationale
Concrete install-time remote bootstrap and execution of an obfuscated credential-oriented payload establishes malicious behavior. The normal ESLint entrypoint does not mitigate the preinstall attack.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- package.json runs `node setup.mjs` as preinstall.
- setup.mjs downloads Bun from github.com and executes `math_init.js` during install.
- math_init.js is a 727KB obfuscated executable payload.
- math_init.js contains `new Function`, `eval`, `.aws`, `child_process`, and token-handling code.
- Payload tail enumerates `ghtoken` values and processes them.
Evidence against
- index.js and rules implement an ESLint plugin; no malicious behavior found there.
- No package-aligned need exists for installing Bun or executing an obfuscated credential-oriented payload.
