ABSTRACT
~~~~~~~~
Sample driver demonstrating how to implement a simple, kernel-only process and command line
monitoring driver for Microsoft Windows.
The driver registers a callback routine to be called whenever a process is
created or deleted. This driver can be used for process creation monitoring. You
can easily expand the driver to also block process creation attempts for specific
parents invoking new processes. This might help to mitigate against typical
attacks origination from office, browser and media playing tools. E.g. ask yourself
"why should my text editor, pdf viewer or browser start cmd.exe or powershell.exe"?
Please note, there exist techniques to bypass such process monitoring (in-memory
attempts, reflective code loading). Hence, such a driver can only be _one_ part
of a monitoring and mitigation strategy. There is no claim to be bullet-proof!
How to install and use
~~~~~~~~~~~~~~~~~~~~~~
To install the driver, just go into the binaries path regarding your architecture of Windows.
Then right-select the .inf and hit "install". You can use one of the cmd-scripts to start,
stop, restart and uninstall the driver. The scripts are located in the project's root folder.
Logging
~~~~~~~
The driver logs events to %windir%\CreateProcessNotifyEx.log
