AI Security Review
scanned 13d ago · by lpm-firewall-aiThe postinstall hook installs and invokes an opaque native binary, leaving its behavior unresolved in this source snapshot. The inspected JavaScript uses a manifest digest for verification, so this supports a warning rather than a confirmed attack or block.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
Package installation runs the postinstall hook.
Impact
The binary can perform behavior unavailable for inspection in this package snapshot; no concrete malicious action was established from the inspected source.
Mechanism
The hook downloads a manifest-selected binary, verifies its SHA-256 digest, installs it, and invokes its skill refresh command.
AI rationale
The postinstall hook installs and invokes an opaque native binary, leaving its behavior unresolved in this source snapshot. The inspected JavaScript uses a manifest digest for verification, so this supports a warning rather than a confirmed attack or block.

Decision evidence
public snapshotAI called this Suspicious at 84.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- The package runs scripts/postinstall.js automatically during installation.
- The postinstall downloads a platform binary using a digest from the manifest.
- The installer invokes the downloaded binary to refresh skills; its behavior is not inspectable in this source snapshot.
Evidence against
- The manifest pins a SHA-256 digest for the downloaded binary.
- The installer restricts downloads to HTTPS and checks the binary against that digest.
