AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe install hook executes a concealed, unrelated payload with remote dynamic evaluation and credential-handling primitives. This is concrete malicious install-time behavior, not package-aligned functionality.
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 installation invokes the preinstall hook.
Impact
Arbitrary code execution and potential credential/data exfiltration during install.
Mechanism
downloaded runtime executes obfuscated payload with remote eval
Attack narrative
On installation, package.json invokes setup.mjs. It either runs a local Bun binary or downloads Bun from GitHub, then executes the obfuscated math_init.js. The payload includes an eval of HTTP response text and credential-oriented GitHub/token logic alongside filesystem and process access, creating an install-time remote-code-execution and exfiltration path unrelated to a commitlint config.

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 728KB heavily obfuscated payload, unrelated to commitlint configuration.
- math_init.js dynamically evaluates HTTP response text with `eval`.
- Obfuscated payload references child_process, filesystem, GitHub tokens, and outbound fetch flows.
Evidence against
- index.js is a small conventional commitlint rules export.
- README describes only commitlint configuration.
