description: This search looks for processes launching netsh.exe. Netsh 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 and
|
|
executing commands via the command line.
|
|
how_to_implement: To successfully implement this search, you must be ingesting data
|
|
that records process activity from your hosts to populate the endpoint data model

known_false_positives: Some VPN applications are known to launch netsh.exe. Outside

|
of these instances, it is unusual for an executable to launch netsh.exe and run
|
|
commands.
