AI Security Review
scanned 13d ago · by lpm-firewall-aiThe inspected JavaScript shows package-aligned binary installation and dispatch, with no concrete attack established in those files. The selected native executable is unavailable for inspection, so its behavior remains unresolved and requires review.
Static reason
One or more suspicious static signals were detected.
Trigger
Package installation when the optional platform binary is missing, followed by running the droid command.
Impact
If the native binary contains harmful behavior, it could run with the user's privileges; the inspected source does not establish whether it does.
Mechanism
The installer retrieves a package tarball from the npm registry, extracts its executable into the package's bin directory, and the command shim runs the selected platform binary.
AI rationale
The inspected JavaScript shows package-aligned binary installation and dispatch, with no concrete attack established in those files. The selected native executable is unavailable for inspection, so its behavior remains unresolved and requires review.

Decision evidence
public snapshotAI called this Manual Review at 78.0% confidence as Unknown with medium false-positive risk.
AI review observations
- The manifest runs install.js after installation and declares version-matched platform binary packages.
- When an optional binary is missing, the installer fetches a package from the npm registry and writes its executable into the package's bin directory.
- The droid command resolves a platform binary and runs it with the user's command-line arguments; its implementation is not included in this snapshot.
Evidence against
- The inspected installer source shows package-local binary setup and replaces the package's own command shim with that binary.

Install Time Lifecycle Scripts

Install-time code downloads an unverified remote native executable, stages it locally, activates an executable path, and exposes it to process execution.

Unverified Remote Native Payload Install
