AI Security Review
scanned 3mo ago · by lpm-firewall-aiConcrete preinstall execution, a downloaded runtime, obfuscated payload code, remote eval, and credential-related paths establish a malicious chain. The benign library entrypoint does not mitigate the install-time behavior.
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; previous stored version diff introduced dangerous source
Trigger
npm installation
Impact
Arbitrary code execution and potential npm/GitHub credential exfiltration.
Mechanism
preinstall downloader executes obfuscated remote-eval payload
Attack narrative
On npm install, package.json invokes setup.mjs. That script obtains Bun if absent and runs math_init.js. The latter is an obfuscated payload containing code that fetches response text and evaluates it, plus npm and GitHub token-related handling. This separates malicious installation behavior from the nominal React component and enables remotely controlled execution.
AI rationale
Concrete preinstall execution, a downloaded runtime, obfuscated payload code, remote eval, and credential-related paths establish a malicious chain. The benign library entrypoint does not mitigate the install-time behavior.

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` in preinstall.
- setup.mjs downloads Bun, then executes math_init.js during installation.
- math_init.js is heavily obfuscated and contains remote response eval.
- math_init.js includes npm and GitHub token-handling paths.
Evidence against
- src/confirm-navigation.tsx is a normal React navigation-confirmation component.
- dist/index.js only re-exports the component.
