Adversaries may check for Internet connectivity on compromised systems. This may be performed during automated discovery and can be accomplished in numerous ways such as using Ping, <code>tracert</code>, and GET requests to websites, or performing initial speed testing to confirm bandwidth.
Adversaries may use the results and responses from these requests to determine if the system is capable of communicating with their C2 servers before attempting to connect to them. The results may also be used to identify routes, redirectors, and proxy servers.

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.
