Others

The following functionalities are not "features", they are basically techniques that may be of interest to you to explore, understand and apply in the development of your driver.

• Searching for a "Zw" api not exported from ntoskrnl.exe at runtime.
• Reflective Loading.
• Support for mapping the driver in memory.

Installation

• Install Rust from here.
• Then follow the instructions provided by microsoft

Supported Platforms

• ✅ Windows 10 / 11 (x64)

Build Instructions

To build the project, ensure you have the Rust toolchain installed.

Driver

To build the driver, first go to the driver folder and then run the following command (When you do the first build you have to be as administrator, but after that you won't need to):

cargo make default --release

This driver can be mapped using kdmapper among other exploit tools, for example, to put mapping support, use the command:

cargo make default --release --features mapper

Client

To build the client, first go into the client folder, then run the following command:

cargo build --release

Since some features of the rootkit are not supported due to the controller mapping, use the following command to build the client with only the commands that can be executed with the mapping:

cargo build --release --features mapper

Setup Instructions

Enable Test Mode or Test Signing Mode

bcdedit /set testsigning on

[Optional] Debug via Windbg

bcdedit /debug on
bcdedit /dbgsettings net hostip:<IP> port:<PORT>

Create / Start Service

You can use Service Control Manager or OSR Driver Loader to load your driver.
