5.2 Dynamic and behavioral detection

: Avoid. If unavoidable, wrap in a robust kernel driver with extensive error handling and test across all target Windows versions.

Defending against injection using Share public link kernel dll injector

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.

: Queues a user-mode APC to an alertable thread in the target process to execute LoadLibrary .

Once attached, the injector must allocate memory inside the target process to host the DLL or shellcode. Instead of relying on user-mode equivalents, the driver calls: Disclaimer: This information is for educational and security

Conversely, many legitimate security products use kernel-level monitoring and injection to protect the system. By injecting their own code into processes, they can monitor for malicious activity and enforce security policies.

Kernel mode can bypass process access restrictions, such as Protected Process Light (PPL), allowing injection into system processes that user-mode applications cannot touch.

| | Kernel-Mode Injection | User-Mode Injection | | :--- | :--- | :--- | | Execution Level | Ring 0 (Kernel Space) | Ring 3 (User Space) | | Privileges | Highest (Full system access) | Limited to process privileges | | Primary Technique | Kernel driver operations, APC, direct syscalls | LoadLibrary , CreateRemoteThread | | Visibility & Detectability | Highly stealthy, bypasses many user-mode hooks | More visible to EDRs and monitoring tools | | Stability Risk | High (System instability potential) | Moderate | | Common Legitimate Use | Advanced game anti-cheat, system-level debugging | Application extension, functional testing |

to shift the driver's virtual memory context into the target process. Allocate Memory: ZwAllocateVirtualMemory

Microsoft maintaining a centralized driver blocklist stops attackers from leveraging known vulnerable, signed third-party drivers (a technique known as BYOVD - Bring Your Own Vulnerable Driver) to execute kernel injection. Bypassing Detection
