Uniqkey - Excessive credential access

Description

Detects an actor reading an abnormally large number of credentials from Uniqkey within a single hour (default threshold: more than 50 access events). Bulk credential reads are rarely part of normal daily work and can indicate a compromised session harvesting secrets, or an insider collecting credentials ahead of departure. Tune the threshold to your organization's baseline, and consider a lower threshold for actors of type scim or system that normally never read credentials interactively.
