T1016 System Network Configuration Discovery
High-Level Description
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. show ip route, show ip interface). On ESXi, adversaries may leverage esxcli to gather network configuration information. For example, the command esxcli network nic list will retrieve the MAC address, while esxcli network ip interface ipv4 get will retrieve the local IPv4 address.
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.

What to Check
How to Test
Atomic Red Team Tests
The following tests are from Atomic Red Team and provide actionable ways to test this technique:
Atomic Test 1: System Network Configuration Discovery on Windows
Identify network configuration information
Upon successful execution, cmd.exe will spawn multiple commands to list network configuration settings. Output will be via stdout.
Supported Platforms: windows
ipconfig /all
netsh interface show interface
arp -a
nbtstat -n
net config
