Detectors
Every Cortex detection rule the toolbox knows about — analytics alerts, BIOCs and correlation rules — in one filterable set.
10 detectors match the current filters. tactic: TA0006 ✕
Download CSV| Type | Name | Severity | Module | Data source / event | ATT&CK |
|---|---|---|---|---|---|
| Analytics | Kerberos Pre-Auth Failures by Host The endpoint failed an unusual number of Kerberos pre-authentications (TGT requests) from at least three users when compared to its baseline. This can indicate a password-spraying attack. | Low | Platform Analytics | Palo Alto Networks Firewall traffic Logs, XDR Agent | Credential Access |
| Analytics | Kerberos Pre-Auth Failures by User and Host The user account on this host failed Kerberos pre-authentications (TGT requests) an unusual number of times. This can indicate a Kerberos brute-force attack. | Informational | Platform Analytics | Palo Alto Networks Firewall traffic Logs, XDR Agent | Credential Access |
| Analytics | Machine Account NTLM Relay An NTLM NTProofStr was seen from more than one source. This indicates that machine account NTLM authentication data has been relayed. | Low | Platform Analytics | Palo Alto Networks Firewall traffic Logs, XDR Agent | 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 | NTLM Hash Harvesting An unusual number of users has sent NTLM to a target in the last hour. This may be indicative of poisoning and NTLM hash harvesting. | Medium | Identity Analytics | Palo Alto Networks Firewall traffic Logs, XDR Agent | Credential Access |
| Analytics | NTLM Password Spray A single host tried to perform an unusual amount of login attempts using NTLM in a short period of time. This may be indicative of a NTLM password spray attack. | Informational | Identity Analytics | Palo Alto Networks Firewall traffic Logs, XDR Agent | Credential Access |
| Analytics | NTLM Relay An NTLM NTProofStr was seen from more than one source. This indicates that NTLM authentication data has been relayed. | Informational | Platform Analytics | Palo Alto Networks Firewall traffic Logs, XDR Agent | Credential Access, Lateral Movement |
| Analytics BIOC | Possible DCSync from a non domain controller Attackers may pose a compromised host as a DC to replicate data to it (DCSync). | Low | Platform Analytics | Palo Alto Networks Firewall traffic Logs, XDR Agent with eXtended Threat Hunting (XTH) | Credential Access, Defense Evasion |
| 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 | 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 |
