Analytics Excessive user account lockouts A high amount of user accounts were locked out from a single source host in a short time period. This may be the result of a brute-force or password spray attack. Low Identity Analytics Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) Credential Access
Analytics External Login Password Spray An abnormally high amount of user account login attempts were seen on a host within a short period of time. This may have resulted from a login password spray attack. Informational Identity Analytics XDR Agent Credential Access
Analytics BIOC First connection from a country in organization A user connected to an SSO service from an unusual country that no one from this organization has connected from before. This may indicate the account was compromised. Informational Identity Analytics AzureAD, Azure SignIn Log, Idira, Duo, Okta, OneLogin, PingOne Credential Access, Resource Development
Analytics BIOC First VPN access attempt from a country in organization A user attempted to connect from an unusual country that no one from this organization has connected from before. This may indicate the account was compromised. Informational Identity Analytics Palo Alto Networks Global Protect, Third-Party VPNs Credential Access, Resource Development
Analytics Impossible traveler - SSO User connected from several remote countries, at least one of which is not commonly used in the organization, within a short period of time. This may indicate the account is compromised. Low Identity Analytics AzureAD, Azure SignIn Log, Idira, Duo, Okta, OneLogin, PingOne Credential Access, Resource Development
Analytics Impossible traveler - VPN A user connected to a VPN service from multiple remote countries in a short period of time, which should normally be impossible. This may indicate the account is compromised. Low Identity Analytics Palo Alto Networks Global Protect, Third-Party VPNs Credential Access, Resource Development
Analytics Intense SSO failures An abnormally high amount of SSO authentication attempts were seen within a short period of time. This could be the outcome of a brute-force login attempt. Informational Identity Analytics AzureAD, Azure SignIn Log, Idira, Duo, Okta, OneLogin, PingOne Credential Access, Initial Access
Analytics Interactive local account enumeration Multiple non-existing accounts attempted interactive local logins to a host within a short period. This may indicate that an attacker has physical access to the host and is trying to enumerate accounts. Low Identity Analytics XDR Agent Discovery, Credential Access
Analytics Internal Login Password Spray An abnormally high amount of user account login attempts were seen from a host within a short period of time. This may have resulted from a login password spray attack. Informational Identity Analytics XDR Agent Credential Access
Analytics IP Rotation Pattern in SSO Spray A high volume of SSO authentication attempts was observed in a short time window. This behavior may indicate a password spray attack targeting multiple accounts. Informational Identity Analytics AzureAD, Azure SignIn Log, Idira, Duo, Okta, OneLogin, PingOne Credential Access, Resource Development
Analytics Multiple user accounts failed login due to account lockouts A high amount of user accounts were locked out from a single source host in a short time period. This may be the result of a brute-force or password spray attack. Low Identity Analytics XDR Agent Credential Access
