Adversaries may look for details about the network configuration and settings, such as IP and/or MAC addresses, of systems they access or through information discovery of remote systems. Several operating system administration utilities exist that can be used to gather this information. Examples include Arp, ipconfig/ifconfig, nbtstat, and route.
Adversaries may also leverage a Network Device CLI on network devices to gather information about configurations and settings, such as IP addresses of configured interfaces and static/dynamic routes (e.g. <code>show ip route</code>, <code>show ip interface</code>).(Citation: US-CERT-TA18-106A)(Citation: Mandiant APT41 Global Intrusion )
Adversaries may use the information from System Network Configuration Discovery during automated discovery to shape follow-on behaviors, including determining certain access within the target network and what actions to do next.

Comments
The Microsoft Sentinel Analytics "Powershell Empire cmdlets seen in command line" query can detect the use of Empire, which can acquire network configuration information including DNS servers and network proxies used by a host, but does not address other procedures.

Comments
Google Security Ops is able to trigger an alert based off processes and command-line arguments that may indicate adversary reconnaissance and information discovery techniques for network configuration settings (e.g., "net config", "ipconfig.exe", "nbtstat.exe).
This technique was scored as minimal based on low or uncertain detection coverage factor.
