Loading and Unloading the Driver

Loading and unloading the driver is easy. For starters, just download the InstDrv tool from rootkit.com.^[6]

^[6] The InstDrv tool was not written by members of rootkit.com; it is hosted there as a convenience.

Rootkit.com

You can find a copy of the InstDrv tool at: www.rootkit.com/vault/hoglund/InstDvr.zip.

This utility will allow you to register and start/stop your driver. Figure 2-1 shows a screenshot of this utility.

When it comes to real-world use, you will certainly need a better method for loading your driver. However, this utility works very well while your rootkit is in development. We cover a real-world deployment program under the section Loading the Rootkit later in this chapter.
