Informational Identity Analytics XDR Agent 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 New Administrative Behavior The endpoint performed new administrative actions, relative to its previously profiled behavior. It is possible that an endpoint will infrequently be used for administrative activities, so analytics is performed using logs collected over a long period of time, also comparing the activity to that of other endpoints. That is, if many endpoints are contacting the same destination with the same administrative activity, then this network activity is less likely to result in this alert. An attacker may be operating on the host, probing other computers and moving laterally inside the network using a trusted computer and credentials. Attackers typically exhibit administrative behaviors when performing reconnaissance and lateral movement.

Medium Email Security Box Audit Log, DropBox, Google Workspace Audit Logs, Microsoft 365 Emails, Office 365 Audit, Okta Audit Log Initial Access
Analytics Random-Looking Domain Names The endpoint performed DNS lookups to an excessively large number of apparently random root domain names. This alert might be symptomatic of malware that is trying to connect to its command and control (C2) servers. The attacker's C2 server runs on one or more domains that can eventually be identified and blacklisted. To avoid this, malware will sometimes use Domain Generation Algorithms (DGA) that produce many unique, random-looking domain names every day. Because only a few of these domains are ever registered, the installed malware must blindly try to access each generated domain name in an effort to locate an active one, which may also trigger the Failed DNS alert. Medium Platform Analytics Palo Alto Networks Firewall EAL Logs, XDR Agent Command and Control
Analytics Rare access to known advertising domains The endpoint performed many connections to unpopular advertising domains. This could indicate the presence of adware on the endpoint. Informational Platform Analytics Palo Alto Networks Firewall EAL Logs, XDR Agent Command and Control, Persistence

Informational Identity Analytics Windows Event Collector, XDR Agent with eXtended Threat Hunting (XTH) Credential Access
Analytics Spam Bot Traffic The endpoint connected to an excessive number of external SMTP servers. A spambot may be trying to send spam email using multiple SMTP servers. Spambots can cause your domain to be blacklisted, and can contain other malicious functionality. The same mechanism can also be used for exfiltration. Some VPN clients can also tunnel data over SMTP. Note: This detection model looks for SMTP connections to external servers, but the volume of traffic is not considered. A count is performed based on the number of domains being contacted, as well as the number of unresolved IP addresses.

This anomaly could suggest that someone is attempting to enumerate subdomains or uncover additional virtual hosts associated with the domain, possibly as part of a reconnaissance effort to identify vulnerable or less-secured entry points into the network. Low Platform Analytics Palo Alto Networks Firewall EAL Logs, XDR Agent Reconnaissance
Analytics Sudden spike in outbound email volume Unusual amount of emails sent by an internal sender to one or more external recipients within a short timeframe. Informational Email Security Microsoft 365 Emails Execution, Credential Access
