AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe benign title component is accompanied by an unrelated, obfuscated preinstall payload that downloads a runtime and supports remote eval and token access. This is concrete malicious 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 preinstall
Impact
Arbitrary code execution and potential GitHub credential exfiltration on the installing machine.
Mechanism
downloads a runtime and executes obfuscated payload with remote eval
Attack narrative
Installing the package runs setup.mjs. It executes math_init.js with Bun, downloading a Bun binary first when necessary. The large obfuscated payload dynamically accesses child_process, fetches remote content, evaluates a response body, and contains token-handling logic, creating an install-time arbitrary-code and credential-exfiltration chain unrelated to the advertised React component.
AI rationale

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 if absent, then executes `math_init.js` during install.
- math_init.js is heavily obfuscated and dynamically loads child_process.
- math_init.js contains remote-response `eval(...)` execution.
- Obfuscated payload includes GitHub-token handling and filesystem/process access.
Evidence against
- src/index.tsx and dist/index.js only implement React document.title management.
- The declared library entrypoint has no malicious runtime behavior.
