it is unusual for netsh.exe to have any child processes in most environments. it makes sense to investigate the child process and verify whether the process spawned is legitimate. we explicitely exclude \"c:\program files\rempl\sedlauncher.exe\" process path since it is a legitimate process by mircosoft.

Description

This search looks for processes launching netsh.exe to execute various commands via the netsh command-line utility. Netsh.exe is a command-line scripting utility that allows you to, either locally or remotely, display or modify the network configuration of a computer that is currently running. Netsh can be used as a persistence proxy technique to execute a helper .dll when netsh.exe is executed. In this search, we are looking for processes spawned by netsh.exe that are executing commands via the command line. Deprecated because we have another detection of the same type.
