Type Name Severity Module Data source / event ATT&CK
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 Possible AS-REP Roasting Attack A user enumerated all accounts that don't require pre-authentication in the organization and specifically requested tickets for those accounts. This is typically a sign of an AS-REP Roasting attack. Medium Identity Analytics XDR Agent, XDR Agent with eXtended Threat Hunting (XTH) Credential Access
Analytics Possible Kerberoasting attack A user enumerated all service principals in the organization and specifically requested weak and deprecated encryption in a ticket request. This is typically a sign of a Kerberoasting attack. Medium Identity Analytics XDR Agent, XDR Agent with eXtended Threat Hunting (XTH) 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 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
