About

A machine learning job has detected an unusually high number of active concurrent sessions initiated by a user, indicating potential privileged access activity. A sudden surge in concurrent active sessions by a user may indicate an attempt to abuse valid credentials for privilege escalation or maintain persistence. Adversaries might be leveraging multiple sessions to execute privileged operations, evade detection, or perform unauthorized actions across different systems.
