Graduation rationale

Matches explicit transfer of sensitive credential files to remote network or cloud-storage destinations in executable hook lines.

Deterministic signal basis

HookSignals command-line analysis over non-comment hook lines for sensitive file paths such as `.env`, `.aws/credentials`, `.ssh/id_rsa`, or `.kube/config` combined with transfer commands like `scp`, `sftp`, `rsync`, `curl`, `aws s3 cp`, `gsutil cp`, or `rclone copy`.

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 ​

Shared hooks should not export local credential files such as SSH keys, cloud credentials, or .env files to remote systems or buckets.

What Triggers ​

SEC683 matches executable hook lines that pair sensitive file paths like .env, ~/.aws/credentials, ~/.ssh/id_rsa, or ~/.kube/config with transfer commands such as scp, rsync, curl --upload-file, aws s3 cp, or gsutil cp.

False Positives ​

Some setup scripts move local files between trusted systems, but committed shared hooks should not silently transfer credential-bearing files as part of normal execution.

Remediation ​

Remove the remote transfer of sensitive credential files from the hook and keep credential material local to the trusted system that owns it.
