Detectors
Every Cortex detection rule the toolbox knows about — analytics alerts, BIOCs and correlation rules — in one filterable set.
22 detectors match the current filters.
Download CSV| Type | Name | Severity | Module | Data source / event | ATT&CK |
|---|---|---|---|---|---|
| Analytics BIOC | A computer account was promoted to DC A computer account was promoted to a domain controller via a User Account Control (UAC) change. | Low | Identity Analytics | Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) | Persistence, Privilege Escalation |
| 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 BIOC | A user modified the CA audit policy A user modified the CA audit policy. This may indicate that an attacker is attempting to cover their tracks before an AD CS attack. | Low | Identity Analytics | Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) | Defense Evasion |
| 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 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 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 BIOC | Masquerading as a default local account A user created a new local account with the name of a default local account, such as Guest and DefaultAccount. An attacker may create a user with these known names to evade detection. | Low | Identity Analytics | Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) | Defense Evasion, Persistence |
| Analytics | Multiple suspicious user accounts were created A user was observed creating multiple rare user accounts. | Low | Identity Analytics | Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) | Persistence |
| 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 | Short-lived user account A user was created and deleted within a short period of time. | Low | Identity Analytics | Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) | Defense Evasion |
| Analytics BIOC | SPNs cleared from a machine account Service principal names were cleared from a machine account. | Low | Identity Analytics | Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) | Privilege Escalation, Persistence |
| Analytics BIOC | Suspicious access of the System Management Container A user accessed the System Management container, which may be an indication of a reconnaissance for site servers. | Low | Identity Analytics | Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) | Reconnaissance |
| Analytics BIOC | Suspicious account attribute modification that matches that of another account Suspicious account attribute modification that matches that of another account. | Low | Identity Analytics | Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) | Privilege Escalation, Persistence |
| 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 modification of the AdminSDHolder's ACL A user modified the AdminSDHolder ACL, which may be an indication of a privilege escalation attack. | Low | Identity Analytics | Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) | Persistence |
| 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 | Suspicious sAMAccountName change The name of a machine account was changed to a sAMAccountName with a missing trailing dollar sign. | Low | Identity Analytics | Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) | Privilege Escalation, Persistence |
| 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 |
| Analytics | User added to the SMS Admins local group A user was added to the SMS Admins local group. This may indicate a potential attack targeting the Microsoft Configuration Manager infrastructure. | Low | Identity Analytics | Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) | Persistence, Privilege Escalation |
| Analytics BIOC | User set insecure CA registry setting for global SANs A user enabled the EDITF_ATTRIBUTESUBJECTALTNAME2 registry flag, allowing custom Subject Alternative Names (SANs) to be specified on all certificate templates. This could enable attackers to bypass security controls by requesting certificates with user-defined SANs. | Low | Identity Analytics | XDR Agent with eXtended Threat Hunting (XTH) | Defense Evasion |
