Kernel Dll Injector ✯

User-mode uses VirtualAllocEx. Kernel-mode uses ZwAllocateVirtualMemory (which is actually a system service that transitions to the kernel). Inside a driver, the injector calls this with the target process’s EPROCESS pointer. Because the call originates in Ring 0, access checks are minimal.

The most sophisticated method for this is often called Manual Mapping. Here is how a ghost enters the machine: kernel dll injector

Instead of politely asking the OS to load the DLL via LoadLibrary, the attacker manually reconstructs the DLL inside the target's memory. User-mode uses VirtualAllocEx

To the User-Mode system, this DLL does not exist. It is not in the list of loaded modules. It is a ghost writing on the walls of memory. To the User-Mode system, this DLL does not exist

EDRs use PsSetCreateProcessNotifyRoutineEx and ObRegisterCallbacks to monitor process creation and handle opening. A good kernel injector will unregister these callbacks or elevate its own priority.

Drivers operate in system context. You can inject into any process, regardless of session ID (e.g., Session 0 isolation isn’t a barrier).
