This project demonstrates the concept of BYOVD, "Bring Your Own Vulnerable Driver," a technique utilized by researchers and security practitioners to study the exploitation of driver vulnerabilities and the manipulation of kernel-mode privileges on Windows systems. The focus is on the utilization of a specific IOCTL (Input/Output Control) code, 0x82730030, in conjunction with the viragt64 driver, which is known for its exploitable characteristics.
The viragt64 driver, listed under the ID 7edb5602-239f-460a-89d6-363ff1059765, is a well-documented example of a driver that exposes several operational risks due to improper handling of IOCTL requests. These vulnerabilities allow for various operations, such as reading and writing to arbitrary memory locations, thereby providing a pathway to elevate privileges or compromise system integrity.
The core component of this project is a C++ application that interfaces with the viragt64 driver using the WinAPI. The application is responsible for:
- Loading the driver using standard service control manager APIs.
- Sending custom commands to the driver via the IOCTL interface.
- Handling responses and errors from the driver to mimic realistic interaction scenarios.
This project is intended for educational and research purposes only. The demonstration of the BYOVD technique and interactions with the viragt64 driver should be conducted in a controlled environment, such as a virtual machine not connected to live networks. Users are advised to exercise caution and understand the implications of interacting with kernel-mode drivers.
To run the project, compile the provided C++ code and execute the binary with administrative privileges on a system where the viragt64 driver is installed and loaded. Ensure that the environment is secure and isolated from production networks to prevent unintended security risks.
