Type Name Severity Module Data source / event ATT&CK
Analytics BIOC A user logged in from an abnormal country or ASN A user logged in from an unusual country or ASN. This may indicate that the account was compromised. Informational Identity Analytics XDR Agent Credential Access, Resource Development
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 Brute-force attempt on a local account A local user account failed to log in multiple times in a short time period. This may indicate a brute-force attack. Informational Identity Analytics XDR Agent Credential Access
Analytics External Login Password Spray An abnormally high amount of user account login attempts were seen on a host within a short period of time. This may have resulted from a login password spray attack. Informational Identity Analytics XDR Agent Credential Access
Analytics BIOC Hydra Password Brute-Force Tool Execution Attackers may use brute-force techniques to gain access to accounts when usernames and/or passwords are unknown. High Platform Analytics XDR Agent Credential Access
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 Internal Login Password Spray An abnormally high amount of user account login attempts were seen from a host within a short period of time. This may have resulted from a login password spray attack. Informational Identity Analytics XDR Agent Credential Access
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 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 A user account attempted to authenticate to a target using NTLM an excessive number of times in a short period. This may indicate an NTLM brute force attack. Informational 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 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 Possible brute force on sudo user A user executed an unusual amount of sudo commands in a short time period. This may indicate an attempt to guess the sudo password. Informational Platform Analytics XDR Agent Credential Access
Analytics Possible brute force or configuration change attempt on cytool An unusual amount of cytool commands were executed in a short period from a user who doesn't usually run these commands. This may indicate an attempt to guess the Administrator password. High Platform Analytics XDR Agent Credential Access
Analytics Possible Brute-Force attempt A user account attempted to authenticate to a target an excessive number of times in a short period. This may indicate a brute-force attack. Informational Identity Analytics XDR Agent Credential Access, Lateral Movement
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 Remote account enumeration Multiple non-existing accounts failed to remotely log in to a host in a short period of time. This may indicate an attacker is trying to remotely enumerate accounts. Informational Identity Analytics XDR Agent Discovery, Credential Access
Analytics SSH authentication brute force attempts A user attempted to authenticate via SSH an excessive number of times in a short period. This may indicate a brute force attack. Informational Identity Analytics XDR Agent Credential Access
Analytics BIOC Suspicious sshpass command execution The sshpass command was executed, This could be an attempt to check for credential stuffing. Low Platform Analytics XDR Agent Credential Access
