AI Security Review
scanned 3mo ago · by lpm-firewall-aiConcrete preinstall execution, downloader behavior, obfuscation, and runtime eval establish malicious install-time remote code execution.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review
Trigger
npm preinstall
Impact
Arbitrary code execution in the installing user's environment.
Mechanism
install-time remote payload retrieval and eval
Attack narrative
The preinstall hook runs setup.mjs, which executes math_init.js directly or first downloads and executes Bun to run it. The unusually large obfuscated math_init.js imports host and network capabilities, retrieves response text, and evaluates it. This provides an install-time remote code-execution chain unrelated to the advertised OAuth plugin.
AI rationale
Concrete preinstall execution, downloader behavior, obfuscation, and runtime eval establish malicious install-time remote code execution.

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 as preinstall.
- setup.mjs executes math_init.js during installation.
- setup.mjs downloads and executes Bun from GitHub if unavailable.
- math_init.js is a 727KB heavily obfuscated executable payload.
- math_init.js imports fs, network, DNS, crypto, OS, and child_process.
- math_init.js fetches response text and passes it to eval().
Evidence against
- src/ and dist/ implement plausible Verdaccio/Okta OAuth flows.
- No benign source path justifies the obfuscated install-time payload.
