| OS | Windows 10 / Windows 11 (x64 only). |
| Vulnerable Driver | The target system must have a loaded vulnerable driver. Kdmapper checks for gdrv.sys by default. If missing, it fails. |
| Secure Boot | Usually must be OFF. |
| HVCI (Memory Integrity) | Must be OFF. |
| Antivirus | Will immediately flag and delete kdmapper.exe (detected as HackTool:Win64/Kdmapper or similar). Add exclusion at your own risk. |
For production drivers, purchase an EV code signing certificate (cost ~$300-500/year) and submit your driver to the Windows Hardware Quality Labs (WHQL). This is the only legal way to distribute kernel drivers widely.
Kdmapper (Kernel Driver Mapper) is a tool utilized to manually map kernel drivers (.sys files) into the Windows kernel space. Kdmapper.exe Download
Typically, to load a kernel driver on Windows, one must use the Windows API or install the driver via the Service Control Manager. This process leaves a digital footprint in the Windows Registry and often requires the driver to be digitally signed (a requirement enforced by Windows since Vista x64).
Kdmapper bypasses these standard mechanisms. It exploits a vulnerability in the Intel IQVM64 driver to gain write access to kernel memory. Once it has this access, it manually allocates memory for the target driver, resolves its dependencies (import address table), and executes it—all without creating a file on the disk or a registry entry. | Item | Requirement | | :--- |
Kdmapper leverages a known vulnerability in the Windows kernel (specifically, the NtQuerySystemInformation call and the Ci!g_CiOptions global flag). The tool:
The result? Any unsigned code can run with Ring 0 (highest) privileges. The result
Because Kdmapper is often flagged as a "HackTool" or "Trojan" by security vendors, finding a clean copy requires caution. Downloading random executables from forums or file-sharing sites is highly dangerous.
