Wyvern Kernel Driver

Wyvern is a kernel driver designed to facilitate the transmission and reception of memory from any process via the computer's kernel.

Features

• Direct Memory Access: Transmit and receive memory from any process.

Installation

To install the Wyvern kernel driver, follow these steps:

1. Clone the Repository:

   git clone https://github.com/snyakocode/wyvernkernel.git
   cd wyvern

2. Build the Project in x64 Version + Run VS as Administrator : Ensure you have the necessary development tools and dependencies for building the project in x64.

3. Drag kernel.sys into KDMAPPER.exe: Use kdmapper to map the driver into memory. Simply drag and drop the kernel.sys file into KDMAPPER.exe.

4. Start CS2: Launch CS2 before starting Wyvern.

5. Start wyvern.exe: Run the wyvern.exe executable to begin using the driver.

Usage

After installation, you can use Wyvern to access process memory directly through provided interfaces. Refer to the documentation for detailed usage instructions.

Exmaple of working with memory data

This example is based on memory handling in CS2

HANDLE driver = driver_utills::open_driver_handle();

DWORD procid = driver_utills::find_proccess_id(L"cs2.exe"): 
const std::uintptr_t client = driver_utills::module_base(procid, L"client.dll"); 

driver::attach_to_process(driver, procid)

driver::write_memory<int>(driver_handle, memory_address(client + offset), value);
driver::read_memory<int>(driver_handle, memory_address(client + offset));

Troubleshooting

Failed to create driver handle

Make sure that driver is installed(drag kernel.sys into kdmapper.exe).

Wyvern.exe deleting by windows defender

Disable windows defender, try to build application again.

Your vulnerable driver list is enabled and have blocked the driver loading, you must disable vulnerable driver list to use kdmapper with intel driver

Disable antivirus, check if there's no enabled AC(faceit, valorant etc.). Try to find your error in kdmapper issues.

Cant build project

Make sure that VS runned as administrator and you already download WindowsDriverKit. Download the individual components with the Spectre add-ons. (Step 1 when installing the driver kit)
