What it detects

This rule detects command line use of the GitHub code search API to enumerate Actions secret reference patterns across organization repositories which attackers use to discover secret names without admin permissions and without generating audit logs. Programmatic code search for the secrets template syntax indicates reconnaissance ahead of secret exfiltration.
