What it detects
This rule flags when an OpenCanary node records a login attempt against its MySQL service. Credential-access attempts against exposed services are a key step in unauthorized access workflows, even when originating from scanners or automated probes. The detection relies on OpenCanary application telemetry indicating the MySQL login attempt event type.
