Type Name Severity Module Data source / event ATT&CK
Analytics A user rejected an SSO request from an unusual country A user rejected an SSO authentication request from an abnormal country. Low Identity Analytics Okta, OneLogin Credential Access, Resource Development
Analytics Account probing A user failed to log in to multiple hosts it never accessed before in a short amount of time. This may indicate the account is compromised and an attacker is probing for a host it can access with those credentials. Low Identity Analytics XDR Agent Initial Access, Credential Access
Analytics Brute-force attempt on a local account A local user account failed to log in multiple times in a short time period. This may indicate a brute-force attack. Informational Identity Analytics XDR Agent Credential Access
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 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 Kerberos Pre-Auth Failures by Host The endpoint failed an unusual number of Kerberos pre-authentications (TGT requests) from at least three users when compared to its baseline. This can indicate a password-spraying attack. Low Platform Analytics Palo Alto Networks Firewall traffic Logs, XDR Agent Credential Access
Analytics Kerberos Pre-Auth Failures by User and Host The user account on this host failed Kerberos pre-authentications (TGT requests) an unusual number of times. This can indicate a Kerberos brute-force attack. Informational Platform Analytics Palo Alto Networks Firewall traffic Logs, XDR Agent Credential Access
Analytics Multiple Suspicious FTP Login Attempts Multiple suspicious FTP sessions were detected, which may indicate a brute-force attempt. Low Platform Analytics Palo Alto Networks Firewall EAL Logs Initial Access, Credential Access
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
Analytics NTLM Brute Force A user account attempted to authenticate to a target using NTLM an excessive number of times in a short period. This may indicate an NTLM brute force attack. Informational Identity Analytics XDR Agent Credential Access
Analytics NTLM Brute Force on a Service Account A service account attempted to authenticate to a target using NTLM an excessive number of times in a short period. This may indicate a NTLM brute-force attack. Low Identity Analytics XDR Agent Credential Access
Analytics NTLM Brute Force on an Administrator Account An administrator account attempted to authenticate using NTLM to a target an excessive number of times in a short period. This may indicate an NTLM brute-force attack. Low Identity Analytics XDR Agent Credential Access
Analytics NTLM Password Spray A single host tried to perform an unusual amount of login attempts using NTLM in a short period of time. This may be indicative of a NTLM password spray attack. Informational Identity Analytics Palo Alto Networks Firewall traffic Logs, XDR Agent Credential Access
Analytics Possible Brute Force in universal authentication An abnormally high amount of authentication attempts via universal authentication were seen within a short period of time. This may indicate a brute-force attack. Informational Identity Analytics Credential Access, Resource Development
