Adversaries may abuse the Windows command shell for execution. The Windows command shell (cmd) is the primary command prompt on Windows systems. The Windows command prompt can be used to control almost any aspect of a system, with various permission levels required for different subsets of commands. The command prompt can be invoked remotely via Remote Services such as SSH.(Citation: SSH in Windows)
Batch files (ex: .bat or .cmd) also provide the shell with a list of sequential commands to run, as well as normal scripting operations such as conditionals and loops. Common uses of batch files include long or repetitive tasks, or the need to run the same set of commands on multiple systems.
Adversaries may leverage cmd to execute various commands and payloads. Common uses include cmd to execute a single command, or abusing cmd interactively with input and output forwarded over a command and control channel.

Comments
This control may detect suspicious usage of PowerShell and the Windows command line. These detections include usage of suspicious arguments, dynamic script construction, and shellcode on the commandline. The following alerts may be generated: "Detected anomalous mix of upper and lower case characters in command-line", "Detected encoded executable in command line data", "Detected obfuscated command line", "Detected suspicious combination of HTA and PowerShell", "Detected suspicious commandline arguments", "Detected suspicious commandline used to start all executables in a directory", "Detected suspicious credentials in commandline", "Dynamic PS script construction", "Suspicious PowerShell Activity Detected", "Suspicious PowerShell cmdlets executed", "Suspicious command execution".
