Download CSV| 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 |
