kdmapper is a kernel driver mapper and loader designed to deploy unsigned binaries into privileged kernel memory. It functions as a manual mapper that resolves imports and relocations to execute unsigned code in a privileged environment.
The tool bypasses driver signature enforcement by leveraging vulnerable signed drivers to gain write access to protected kernel memory regions. It includes a kernel offset resolver that parses debug symbol files to identify correct memory addresses across different operating system builds.
To maintain stealth, the project implements driver trace obfuscation by scrubbing kernel memory tables and removing entries from system driver lists. It manages the allocation of non-paged kernel memory and parses portable executable structures to determine memory requirements and entry point locations.
