Type Name Severity Module Data source / event ATT&CK
Analytics BIOC A process queried the ADFS database decryption key via LDAP A process queried the ADFS database decryption key (DKM key) via LDAP. Low Identity Analytics XDR Agent with eXtended Threat Hunting (XTH) Credential Access
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 A user sent multiple TGT requests to irregular service A user sent multiple TGT requests to services other than KRBTGT and KADMIN. This is typically a sign of a Kerberoasting attack. Low Identity Analytics Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) Credential Access
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 BIOC Discovery of accounts with pre-authentication disabled via LDAP A possible discovery of accounts without pre-authentication required via LDAP was performed. Such enumeration may be used during attacks against the organization. Low Identity Analytics XDR Agent with eXtended Threat Hunting (XTH) Discovery, 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 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 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 BIOC LDAP AD CS Enumeration via Attack Tool A user sent a suspicious AD CS enumeration query via LDAP. The query is associated with an AD CS LDAP enumeration tool that may be used during attacks against the organization. Low Identity Analytics XDR Agent with eXtended Threat Hunting (XTH) Discovery, 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 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 Possible external RDP Brute-Force Multiple failed remote logins originated from an external IP with at least one successful login. This may indicate a successful brute-force attack. Low Identity Analytics XDR Agent Credential Access
Analytics Potential extraction of NAA Account Credentials in Microsoft Configuration Manager Possible user attempt to deobfuscate Network Access Account (NAA) credentials in Microsoft Configuration Manager. This may indicate a compromised account. Low Identity Analytics AzureAD Audit Log, Microsoft Graph Logs, Office 365 Audit, Okta, Palo Alto Networks Global Protect, Third-Party VPNs, XDR Agent, XDR Agent with eXtended Threat Hunting (XTH) Credential Access, Defense Evasion
Analytics Suspicious Kerberos Pre-Auth Failures by Host An endpoint failed unusual number of Kerberos pre-authentications (TGT requests) which may indicate a password-spraying attack. Low Identity Analytics XDR Agent with eXtended Threat Hunting (XTH) Credential Access
Analytics BIOC Suspicious Print System Remote Protocol usage by a process A host which is trusted for unconstrained delegation initiated an SMB connection to a DC using the Print System Remote Protocol. An attacker can abuse such sessions for relay attacks. Low Identity Analytics XDR Agent with eXtended Threat Hunting (XTH) Credential Access
Analytics BIOC Unusual CertLog Remote File Write A remote host wrote to a certificate log file via RPC over SMB, which may indicate the use of an AD CS attack tool like Certipy. This behavior is commonly associated with certificate-based authentication attacks. Low Identity Analytics XDR Agent with eXtended Threat Hunting (XTH) Credential Access
Analytics BIOC Unusual Encrypting File System Remote call (EFSRPC) to domain controller An unusual Encrypting File System Remote call (EFSRPC) was made to a domain controller. Low Identity Analytics XDR Agent with eXtended Threat Hunting (XTH) Credential Access
