Type Name Severity Module Data source / event ATT&CK
Analytics Abnormal connections to a dormant host from a newly seen endpoint The endpoint has performed multiple connections to an endpoint that is relatively inactive on the network. Informational Platform Analytics Palo Alto Networks Firewall traffic Logs, XDR Agent Discovery
Analytics Abnormal ICMP echo (PING) to multiple hosts An endpoint performed an abnormal ICMP echo (PING) to multiple hosts on the network. Low Platform Analytics XDR Agent Discovery
Analytics An internal Cloud resource performed port scan on external networks An internal cloud resource attempted to connect to the same destination port of multiple external IP addresses. This may be a result of the cloud resource being hijacked by an attacker. Attackers perform port scans on a specific destination port for reconnaissance purposes, to detect known vulnerable services that accept connections in the specific port, and perform targeted attacks against them. Medium Cortex Cloud XDR Agent Discovery, Impact
Analytics BIOC Cached credentials discovery with cmdkey Cmdkey is a built-in Windows tool that can cache domain user credentials for use on specific target machines, Attackers can access cached user credentials using cmdkey /list. Low Platform Analytics XDR Agent Credential Access, Discovery
Analytics BIOC Discovery of host users via WMIC Attackers may use wmic.exe to list the users of a host, and potentially its owner. Informational Platform Analytics XDR Agent Discovery
Analytics Failed Connections The endpoint has failed connections to other endpoints that have been inactive for more than 24 hours, or that Cortex XDR Analytics has never seen on the network. The endpoint has made an abnormally large number of these failed connections and/or is attempting to connect to an abnormal mixture of missing or inactive endpoints. Your network might contain legitimate scanners that could cause a false positive for this alert. Cortex XDR Analytics attempts to filter these out by checking if a scanner has been active for a long consecutive period of time. Consequently, if this alert is seen, it represents new activity on your network. An attacker may be trying to move laterally, or to scan different parts of the network to look for other endpoints that expose a specific service. Worms also perform a similar activity to automatically infect additional hosts in the network. Low Platform Analytics Palo Alto Networks Firewall traffic Logs, XDR Agent, Third-Party Firewalls Discovery

Analytics BIOC Kubernetes API server communication from within a pod The Kubernetes API server was accessed from within a pod. Informational Platform Analytics XDR Agent Discovery
Analytics Kubernetes environment enumeration activity Multiple resources within a Kubernetes cluster were enumerated. This may indicate an adversary attempting to map the Kubernetes environment and discover resources that may assist to perform additional attacks within the environment. Informational Platform Analytics XDR Agent Discovery
Analytics BIOC Kubernetes version disclosure The Kubernetes API server was inquired about the Kubernetes version by a process from within a pod. Informational Platform Analytics XDR Agent Discovery
Analytics BIOC Kubernetes vulnerability scanner activity A Kubernetes cluster was scanned by a known vulnerability scanner. Medium Platform Analytics XDR Agent Execution, Discovery
Analytics BIOC LDAP traffic from non-standard process LDAP traffic is usually performed by a standard set of processes. The endpoint had a non-standard process communicating over ports normally used by LDAP. This may be indicative of Active Directory domain enumeration, which may be used during attacks against the organization. Informational Platform Analytics XDR Agent Discovery
Analytics BIOC Linux network share discovery An adversary might use known tools to discover SMB shares within the compromised network. Informational Platform Analytics XDR Agent Discovery
Analytics BIOC Local account discovery One of several local account discovery commands were executed. Informational Platform Analytics XDR Agent Discovery
Analytics Multiple discovery commands The alerted causality performed multiple discovery commands in a short timeframe. Low Platform Analytics XDR Agent Discovery
Analytics Multiple discovery commands on a Linux host by the same process The alerted process performed multiple consecutive discovery commands in a short timeframe. Informational Platform Analytics XDR Agent Discovery
Analytics Multiple discovery commands on a Windows host by the same process The alerted process performed multiple discovery commands in a short timeframe. Low Platform Analytics XDR Agent Discovery
Analytics Multiple discovery-like commands The alerted process performed multiple consecutive discovery commands in a short time frame. Informational Platform Analytics XDR Agent Discovery
Analytics BIOC Permission Groups discovery commands Permission group discovery command execution. Informational Platform Analytics XDR Agent Discovery
Analytics Port Sweep The endpoint connected, or attempted to connect, to multiple hosts using privileged ports that serve a well-defined function. Attackers perform port sweep for reconnaissance purposes, to find computers or servers that accept connections on these ports, and to find vulnerable services that can be exploited. Coverage for port sweeps using data arriving solely from Cortex agents is incomplete. Informational Platform Analytics Palo Alto Networks Firewall traffic Logs, XDR Agent, Third-Party Firewalls Discovery
Analytics BIOC Possible network service discovery via command-line tool An attacker may use command-line utilities to discover open ports and services on a remote host. Low Platform Analytics XDR Agent Discovery
Analytics BIOC Possible network sniffing attempt via tcpdump or tshark Attackers may monitor network traffic for cleartext credentials or to learn the network's configuration. Low Platform Analytics XDR Agent Credential Access, Discovery

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 BIOC SMB Traffic from Non-Standard Process SMB traffic is usually performed by a standard set of privileged processes through designated ports. The endpoint had a non-standard process communicating over ports normally used by SMB. An attacker might be moving laterally by using tools that implement a custom version of the SMB protocol.
