AI Security Review
scanned 5d ago · by lpm-firewall-aiThe package sends undisclosed, limited runtime usage telemetry to its vendor, which warrants a warning under the telemetry rules. The credential and network indicators otherwise correspond to advertised license validation and fetching paid rules.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
A free CLI run in an interactive terminal sends a use event. An absent or invalid license can also send a paywall event in an interactive terminal or MCP session.
Impact
The vendor learns that the package was used and whether a free run or license prompt occurred. The observed payload does not include project data or credentials.
Mechanism
HTTPS POST sends the package slug, source, and event reason to the vendor analytics endpoint. Environment variables can disable the pings.
AI rationale
The package sends undisclosed, limited runtime usage telemetry to its vendor, which warrants a warning under the telemetry rules. The credential and network indicators otherwise correspond to advertised license validation and fetching paid rules.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- An ordinary free CLI run sends `{ t: 'use', slug, src: 'cli', why: 'free' }` to `getreadystack.com/api/ev`; it skips CI and supports telemetry opt-outs.
- The CLI calls this ping after a free run, so it is runtime telemetry rather than install-time activity.
- When a license is absent or invalid, the package can send a similar slug/source/reason ping, with the same opt-outs.
- The license-key validation and paid rules feed support the package’s advertised licensed scanning features.
Evidence against
- The telemetry payload contains package and usage labels, not file contents, credentials, hostnames, or usernames.
- Telemetry is limited to interactive terminal or MCP use for the paywall ping; the general use ping requires a TTY.
- `DO_NOT_TRACK=1`, `READYSTACK_NO_TELEMETRY`, and `CI` suppress the telemetry.
- The README describes the paid scanning features and license flow; there are no lifecycle scripts in the manifest.
