AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe explicit preinstall chain executes an obfuscated payload that evaluates remotely fetched content. This is concrete malicious install-time behavior, not package-aligned component 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 install / preinstall
Impact
Arbitrary attacker-supplied code can execute with the installing user's privileges; credential/token theft is indicated.
Mechanism
remote payload retrieval and eval during install
Attack narrative
Installing the package invokes setup.mjs. It uses an installed Bun binary or downloads one, then executes the obfuscated math_init.js file. That payload contains runtime fetches whose response text is passed to eval, plus GitHub-token-related logic and child-process access, creating an install-time remote-code-execution and likely credential-exfiltration chain.
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 setup.mjs via preinstall.
- setup.mjs downloads and executes Bun on math_init.js.
- math_init.js is heavily obfuscated and executes at install time.
- math_init.js fetches response text and passes it to eval.
- math_init.js contains GitHub-token handling and child-process use.
Evidence against
- setup.mjs downloads Bun from the explicit official GitHub release URL.
- No legitimate component implementation or index.js is present.
