Graduation rationale

Checks committed Claude settings command hooks for secret-bearing exfil over insecure HTTP.

Deterministic signal basis

ClaudeSettingsSignals command-hook string analysis over committed hook entries with type == command for `http://` endpoints gated by concurrent secret markers in a network-capable command path.

Canonical note

Structural stable rule positioned as an explicit threat-review control: high-signal malicious, credential-bearing, or spyware-like behavior that stays opt-in rather than shaping the quiet default.

Why It Matters ​

Plain HTTP secret exfiltration compounds two risks at once: unauthorized secret export and transport without confidentiality guarantees.

What Triggers ​

SEC678 matches committed Claude command hooks where a secret-bearing network send targets an explicit http:// endpoint.

False Positives ​

Shared committed hooks should not emit real secret values over plain HTTP. Test-only examples should stay out of production-facing committed settings.

Remediation ​

Remove the insecure secret-bearing HTTP request or redesign the hook so secrets never leave the trusted boundary.
