AI Security Review
scanned 11d ago · by lpm-firewall-aiThe executable startup path automatically sends a license key to the publisher’s feed host when its cache is absent or stale. This is an unconsented credential transfer to a package-selected recipient, so the package is malicious.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
Running the CLI when a license key is configured and the saved rule feed is missing or stale.
Impact
The publisher’s host receives a license credential that is also used with the license validation service.
Mechanism
Startup calls the feed helper, which adds the key to a request to getreadystack.com.
Attack narrative
On CLI startup, the package requests its publisher’s rule feed. When a license key is configured and the feed cache is missing or stale, the request includes that key in its query to getreadystack.com. The key is also used for validation at api.polar.sh, so the feed request discloses the credential to a separate recipient without a recipient-specific consent gate.
AI rationale
The executable startup path automatically sends a license key to the publisher’s feed host when its cache is absent or stale. This is an unconsented credential transfer to a package-selected recipient, so the package is malicious.

Decision evidence
public snapshotAI called this Malicious at 98.0% confidence as Malware with low false-positive risk.
Evidence for block
- The package exposes cli.js as its executable entrypoint.
- The CLI requests the license rule feed at startup.
- The feed helper uses the environment or saved license key and sends it when the cache is absent or stale.
- The feed request places the license key in a query to getreadystack.com.
- License keys are also sent to api.polar.sh for validation, their intended service.
Evidence against
- The feed request requires a license key and skips transmission while its cached feed is fresh.
