Download CSV| Type | Name | Severity | Module | Data source / event | ATT&CK |
|---|---|---|---|---|---|
| BIOC | Kerberos service ticket request in PowerShell command Asking for a specific Kerberos service ticket can indicate an attacker's attempt to "Kerberoast" or use the ticket directly. | High | Platform Analytics | Process execution | Credential Access, Lateral Movement |
| Analytics | Multiple Weakly-Encrypted Kerberos Tickets Received A user accessed a number of services associated with user accounts in the 10 minutes leading to the alert, generating a number of weakly encrypted Kerberos TGS (ticket granting service) tickets that is significantly larger than the number of weakly encrypted TGS tickets received by that user in the 30 days leading to the alert. Services associated with user accounts are a common target for Kerberoasting due to default weak encryption. | Low | Platform Analytics | Palo Alto Networks Firewall traffic Logs, XDR Agent | Credential Access |
| Analytics BIOC | Possible Kerberoasting without SPNs A user specifically requested weak and deprecated encryption in a Kerberos TGS request. This provides easy-to-crack hashes, and is typically a sign of a Kerberoasting attack. The requested service was specified by using a suspicious SPN type, which is often used by Kerberoasting tools to request by SAN instead of SPN. | Low | Platform Analytics | Palo Alto Networks Firewall traffic Logs, XDR Agent | Credential Access |
| Analytics | Suspicious LDAP queries followed by shared folder access The user executed suspicious LDAP queries shortly before accessing a shared folder. This behavior may be indicative of Rubeus activity involving Kerberos ticket forgery, such as Golden Ticket or Silver Ticket attacks. | Low | Platform Analytics | XDR Agent with eXtended Threat Hunting (XTH) | Credential Access |
| Analytics BIOC | Suspicious setspn.exe execution A Service Principal Name (SPN) is a unique identifier for a service, mapped to a specific account. Setspn.exe can be used to retrieve SPN information, which may indicate an attacker's attempt to "Kerberoast". | Low | Platform Analytics | XDR Agent | Credential Access |
| Analytics BIOC | Weakly-Encrypted Kerberos Ticket Requested A user specifically requested weak and deprecated encryption in a Kerberos TGS request. This provides easy-to-crack hashes and is typically a sign of a Kerberoasting attack. | Low | Platform Analytics | Palo Alto Networks Firewall traffic Logs, XDR Agent | Credential Access |
