Azure AD Multiple AppIDs and UserAgents Authentication Spike

The analytic detects unusual authentication activity in Azure AD, specifically when a single user account has over 8 authentication attempts using 3+ unique application IDs and 5+ unique user agents within a short period. This behavior is significant as it may indicate an adversary probing for MFA requirements or attempting to bypass MFA. If confirmed malicious, it suggests a compromised account, potentially leading to further exploitation, lateral movement, and data exfiltration. Early detection is crucial to prevent substantial harm.
