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.

OriginalFileName: netsh.exe
|
|
selection2:

condition: (selection1 or selection2)
|
|
how_to_implement: To successfully implement this search you need to be ingesting information
|
|
on process that include the name of the process responsible for the changes from
|
|
your endpoints into the `Endpoint` datamodel in the `Processes` node. In addition,
|
|
confirm the latest CIM App 4.20 or higher is installed and the latest TA for the
|
|
endpoint product.
|
|
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.
