About

A machine learning job has detected a user accessing an uncommon group name for privileged operations, indicating potential privileged access activity. This indicates that a user has accessed a group name that is unusual for their typical operations, particularly for actions requiring elevated privileges. This could point to an attempt to manipulate group memberships or escalate privileges on a system.
