AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe install hook provides a concrete, unconsented execution chain into an obfuscated credential-focused payload with remote eval. This is malicious behavior, not package-aligned configuration tooling.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review
Trigger
npm install
Impact
Arbitrary code execution and compromise of developer credentials
Mechanism
preinstall downloader launches obfuscated credential-stealing remote-eval payload
Attack narrative
On installation, package.json runs setup.mjs. That script downloads or locates Bun and executes the bundled math_init.js. The obfuscated payload uses dynamic module loading, inspects credential sources including GitHub tokens, sends data over network requests, and evals fetched response content, enabling attacker-controlled execution during install.

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 and executes Bun to run math_init.js.
- math_init.js is heavily obfuscated and executes fetched content with eval.
- math_init.js enumerates credential sources and handles GitHub tokens.
Evidence against
- Normal workspace configuration helpers exist in index.js/index.mjs.
- Bun download targets github.com, but it launches the bundled payload.
