Type Name Severity Module Data source / event ATT&CK
Analytics BIOC A disabled user attempted to log in A disabled user attempted to log in. Informational Identity Analytics XDR Agent Initial Access
Analytics BIOC A rare local administrator login A rare local administrator login was observed. This may indicate an attempt to change sensitive settings on the host. Informational Identity Analytics XDR Agent Initial Access
Analytics A user authenticated with weak NTLM to multiple hosts A user account authenticated to multiple hosts via NTLMv1 or LM authentication for the first time in the past 30 days. Informational Identity Analytics XDR Agent Lateral Movement
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 A user logged on to multiple workstations via Schannel A user logged on to multiple workstations with a certificate via Schannel. This may be indicative of a compromised account. Informational Identity Analytics XDR Agent Persistence, Privilege Escalation, Credential Access
Analytics BIOC Abnormal User Login to Domain Controller A user account has successfully logged on to a Domain Controller (DC), generating a Windows Event Log. This may be a sign of DC and Active Directory (AD) compromise. Informational Identity Analytics XDR Agent Lateral Movement, Privilege Escalation
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 Interactive login by a machine account A machine account performed an interactive or remote interactive login. Informational Identity Analytics XDR Agent Initial Access
Analytics BIOC Interactive login from a shared user account A user account has been seen active on multiple hosts. Shared accounts are often considered 'bad practice' and may present multiple security risks to the organization. Informational Identity Analytics XDR Agent Initial 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 BIOC Linux local user account creation A user executed a process associated with user account creation. Informational Identity Analytics XDR Agent Persistence
Analytics BIOC Login by a dormant user A dormant user logged on after having been unused for a month or longer. This may indicate the account is misused by an attacker. Informational Identity Analytics XDR Agent Defense Evasion
Analytics Microsoft Configuration Manager device registration and policy request A user registered a device and requested a Microsoft Configuration Manager policy. Informational Identity Analytics XDR Agent Credential Access, Privilege Escalation
Analytics Multiple Rare Process Executions in Organization Multiple unusual processes were executed in the organization. This may be indicative of a compromised account. Informational Identity Analytics XDR Agent Execution
Analytics Multiple users authenticated with weak NTLM to a host Multiple user accounts authenticated to a host via NTLMv1 or LM authentication for the first time in the past 30 days. This may be a result of an NTLM downgrade attack A downgrade attack may force the client to authenticate with a weaker hash/protocol (such as NTLMv1 or even LM) instead of NTLMv2. Informational Identity Analytics XDR Agent Lateral Movement
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 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 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 TGT reuse from different hosts (pass the ticket) We observed two different hosts sending TGS using the same TGT. This may indicate a TGT was stolen and passed to another host. Informational Identity Analytics XDR Agent Lateral Movement
Analytics Potential NTLM Relay Attack Multiple NTLM authentications were made to the same workstation and user from different IPs. This might indicate a potential NTLM Relay attack. Informational Identity Analytics XDR Agent Credential Access, Lateral Movement
Analytics Potential NTLM Relay Attack against a Microsoft Configuration Manager Site Server Multiple NTLM authentications were made to the same Microsoft Configuration Manager site server and user from different IPs in a short period of time. This might indicate a potential NTLM Relay attack. Informational Identity Analytics XDR Agent Credential Access, Lateral Movement
Analytics BIOC Rare LOLBIN Process Execution by User A user executed a living-off-the-land binary (LOLBIN) process that is unusual for this user. This may be indicative of a compromised account. Informational Identity Analytics XDR Agent Execution
Analytics BIOC Rare NTLM Access By User To Host An unusual NTLM authentication attempt by a user to a host. This may indicate the use of stolen credentials or access tokens to access restricted hosts. Informational Identity Analytics Palo Alto Networks Firewall traffic Logs, XDR Agent Lateral Movement
Analytics BIOC Rare NTLM Usage by User Rare authentication by user account to host via NTLM. The user has not authenticated with NTLM in the past 30 days. This may be indicative of downgrade attacks from Kerberos to NTLM. Informational Identity Analytics Palo Alto Networks Firewall EAL Logs, XDR Agent Lateral Movement
Analytics BIOC Rare process execution by user An unusual process was executed by a user. This may be indicative of a compromised account. Informational Identity Analytics XDR Agent Execution
Analytics BIOC Rare process execution in organization An unusual process was executed in the organization. This may be indicative of a compromised account. Informational Identity Analytics XDR Agent Execution
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 External RDP Login An unusual successful RDP connection by a user from an external IP. This may be indicative of using stolen credentials or malicious activity. Informational Identity Analytics XDR Agent Initial Access
Analytics BIOC Suspicious NTLM authentication with machine account A suspicious NTLM authentication attempt was made by a machine account. Informational Identity Analytics Palo Alto Networks Firewall EAL Logs, XDR Agent Credential Access
Analytics BIOC Suspicious successful RDP connection to localhost An unusual process created a successful RDP connection to localhost. This may indicate the use of a tunnel to bypass a firewall. Informational Identity Analytics XDR Agent Initial Access
Analytics BIOC Unusual weak authentication by user A user account authenticated to a host via NTLMv1 or LM authentication for the first time in the past 30 days. This may be indicative of an NTLM downgrade attack A downgrade attack may force the client to authenticate with a weaker hash/protocol (such as NTLMv1 or even LM) instead of NTLMv2.
