This rule detects potential credential abuse of service principals or applications by identifying an unusual number of activities from a single service principal or application across multiple distinct IP addresses within a one-hour window. It specifically monitors sign-in logs for applications like 'Azure CLI', 'GitHub', or 'CustomApp' where the user type is 'ServicePrincipal' or 'Application'. A threshold of more than 10 activities and more than 2 distinct IP addresses within an hour triggers an alert.
