Overview

TitanHide is a driver intended to hide debuggers from certain processes. The driver hooks various Nt* kernel functions (using SSDT table hooks) and modifies the return values of the original functions. To hide a process, you must pass a simple structure with a ProcessID and the hiding option(s) to enable, to the driver. The internal API is designed to add hooks with little effort, which means adding features is really easy.

Features

  • ProcessDebugFlags (NtQueryInformationProcess)
  • ProcessDebugPort (NtQueryInformationProcess)
  • ProcessDebugObjectHandle (NtQueryInformationProcess)
  • DebugObject (NtQueryObject)
  • SystemKernelDebuggerInformation (NtQuerySystemInformation)
  • SystemDebugControl (NtSystemDebugControl)
  • NtClose (STATUS_INVALID_HANDLE exception)
  • ThreadHideFromDebugger (NtSetInformationThread)
  • Protect DRx (HW BPs) (NtSetContextThread)

Test environments

  • Windows 8.1 x64 & x86
  • Windows 7 x64 & x86 (SP1)
  • Windows XP x86 (SP3)
  • Windows XP x64 (SP1)

There is partial Windows 10 support. Hooking works, but finding the SSDT will currently fail. If you must run TitanHide on Windows 10, a workaround is to find the RVA of KeServiceDescriptorTable in ntoskrnl.exe and hardcode it in SSDTFind().

Compiling

  1. Install Visual Studio 2013 (Express Edition untested).
  2. Install the WDK.
  3. Open TitanHide.sln and hit compile!

Installation Method 1

  1. Copy TitanHide.sys to %systemroot%\system32\drivers.
  2. Run the command sc create TitanHide binPath= %systemroot%\system32\drivers\TitanHide.sys type= kernel to create the TitanHide service.
  3. Run the command sc start TitanHide to start the TitanHide service.
  4. Run the command sc query TitanHide to check if TitanHide is running.

Installation Method 2

  1. Copy TitanHide.sys to %systemroot%\system32\drivers.
  2. Start ServiceManager.exe (available on the download page).
  3. Delete the old service (when present).
  4. Install a new service (specify the full path to TitanHide.sys).
  5. Start the service you just created.
  6. Use TitanHideGUI.exe to set hide options for a PID.

Testsigning & PatchGuard

To enable testsigning run the following command:

bcdedit /set testsigning on

To disable PatchGuard, find a tool like KPP Destroyer to disable it (Google is your friend). To check if TitanHide is working correctly, use DebugPrint or check C:\TitanHide.log

Remarks

  • When using x64dbg, you can use the TitanHide plugin (available on the download page).
  • When using EsetNod32 AV, disable "Realtime File Protection", to prevent a BSOD when starting TitanHide. You can re-enable it right afterwards
