AI Security Review
scanned 2d ago · by lpm-firewall-aiThe flagged install hook only prints a welcome banner. The remote installer is part of the agent setup flow, and audit data sharing is presented to the user with a separate choice for sending code extracts to the judge.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
The postinstall hook runs during installation; audit uploads and agent installation are reached through CLI workflows.
Impact
No malicious behavior was found. Audit data sharing is disclosed, and the install hook performs no network action.
Mechanism
The hook prints a welcome banner. Audit sharing is presented to the user, while agent setup fetches an installer from Kerno’s agent-runtimes repository.
AI rationale
The flagged install hook only prints a welcome banner. The remote installer is part of the agent setup flow, and audit data sharing is presented to the user with a separate choice for sending code extracts to the judge.

Decision evidence
public snapshotAI called this Clean at 92.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest exposes cli.js as the kerno command-line entry point.
- The postinstall hook prints a banner to /dev/tty or stderr.
- The CLI asks whether to send the finished audit run to Kerno and says the choice can be changed later.
- The CLI separately asks permission for the judge to read code extracts.
- Audit usage events are sent only when the saved sharing choice enables uploads.
- The agent installer fetches its install script from Kerno’s agent-runtimes repository.
