| 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 | Platform Analytics | Palo Alto Networks Firewall traffic Logs, XDR Agent, Third-Party Firewalls | Lateral Movement |

| 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 BIOC | RDP Connection to localhost An RDP connection to localhost can be used for privilege escalation by leveraging Windows accessibility features. | Medium | Platform Analytics | XDR Agent | Lateral Movement |

| Analytics BIOC | Windows LOLBIN executable connected to a rare external host Scripts connecting to external IP addresses may be sanctioned IT scripts. However, when those external IP addresses are only receiving connections from a few specific endpoints in the organization, these scripts may be an indicator of more suspicious activity.
