System Network Configuration Discovery
Adversaries may look for details about the network configuration and settings 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 use the information from System Network Configuration Discovery during automated discovery to shape follow-on behaviors, including whether or not the adversary fully infects the target and/or attempts specific actions.
Agent.btz collects the network adapter’s IP and MAC address as well as IP addresses of the network adapter’s default gateway, primary/secondary WINS, DHCP, and DNS servers, and saves them into a log file.
Arp can be used to display ARP configuration information on the host.
ifconfig can be used to display adapter configuration on Unix systems, including information for TCP/IP, DNS, and DHCP.
ipconfig can be used to display adapter configuration on Windows systems, including information for TCP/IP, DNS, and DHCP.
Kwampirs collects network adapter and interface information by using the commands
Lazarus Group malware IndiaIndia obtains and sends to its C2 server information about the first network interface card’s configuration, including IP address, gateways, subnet mask, DHCP information, and whether WINS is available.
nbtstat can be used to discover local NetBIOS domain names.
route can be used to discover routing configuration information.
Turla surveys a system upon check-in to discover network configuration details using the
This type of attack technique cannot be easily mitigated with preventive controls since it is based on the abuse of system features.
System and network discovery techniques normally occur throughout an operation as an adversary learns the environment. Data and events should not be viewed in isolation, but as part of a chain of behavior that could lead to other activities, such as Lateral Movement, based on the information obtained.
Monitor processes and command-line arguments for actions that could be taken to gather system and network information. Remote access tools with built-in features may interact directly with the Windows API to gather information. Information may also be acquired through Windows system management tools such as Windows Management Instrumentation and PowerShell.
