win10 1909逆向----通過全局句柄PspCidTable,枚舉所有進程【目前只考慮句柄表爲兩層結構的解析，因爲懶】。

先看效果圖：

再放代碼：

#include <ntddk.h>
#include "Handle.h"

VOID Unload(PDRIVER_OBJECT pDriverObject)
{
	KdPrint(("end\n"));
}

NTSTATUS DriverEntry(PDRIVER_OBJECT pDriverObject, PUNICODE_STRING pRegPath)
{
	NTSTATUS status = STATUS_SUCCESS;
	KdPrint(("start\n"));
	pDriverObject->DriverUnload = Unload;
	HANDLE hThread;
	PUCHAR System = (PUCHAR)PsInitialSystemProcess;
	//第一步得到全局句柄表
	PHANDLE_TABLE PspCidTable=0;
	PUCHAR  var = (PUCHAR)PsLookupThreadByThreadId;
	for (int i = 0; i < 100; i++)
	{

		if (*var == 0xf7 && *(var + 1) == 0xc1)
		{
			PspCidTable = *(PLONG32)(var - 4) & 0xFFFFFFFF;
			PspCidTable = *(PUINT64)(var + (LONG32)PspCidTable);
		}
		var++;
	}
	//第二步，得到進程的INDEX
	 pObjectType = ObGetObjectType(PsInitialSystemProcess);
	 TypeIndex = pObjectType->Index;
	//第二步解析
	AnalyticHandle(PspCidTable);

	return status;
}

PVOID NTAPI AnalyticHandle(IN PHANDLE_TABLE HandleTable)
{
	
	INT64 TableBase = 0;
	INT64 TableLevel = 0;
	PUINT64 varTableEntry = 0;
	PHANDLE_TABLE varHandleTable = HandleTable;
	TableBase = varHandleTable->TableCode;
	TableLevel = TableBase & 3;
	TableBase = TableBase & 0xFFFFFFFFFFFFFFFC;
	int var_i = 0;
	int var_j = 0;
    PUCHAR Object = 0;
	UCHAR Index = 0;
	if (TableLevel == 1)
	{
		for (; *(PUINT64)TableBase && ((var_i++)<0x200); TableBase += 8)
		{
		    varTableEntry = *(PUINT64)TableBase;
			//因爲第一個和最後一個不用
			varTableEntry += 2;
			var_j = 0;
			while((var_j++) < 0xFF)
			{
				if (*varTableEntry)
				{
					//全局句柄表得到的是Object 內核句柄表得到的是Object_Header	
					Object=(((INT64)*varTableEntry) >> 0x10) & 0xFFFFFFFFFFFFFFF0;
			        //解析Index
					pObjectType = ObGetObjectType(Object);
					if (pObjectType->Index == TypeIndex)
					{
						KdPrint(("%s\n", PsGetProcessImageFileName(Object)));
					}
					
					//不讓系統卡死
					KSleep(10);
									
				}
				varTableEntry += 2;
				
			}
			
		
		}
		
	}
	return 0;

}
VOID KSleep(LONG MilliSecond)

{

	LARGE_INTEGER Interval = { 0 };

	Interval.QuadPart = DELAY_ONE_MILLISECOND;

	Interval.QuadPart *= MilliSecond;

	KeDelayExecutionThread(KernelMode, 0, &Interval);

}

 

再放頭文件：

#include <ntddk.h>
#define DELAY_ONE_MICROSECOND   (-10)
#define DELAY_ONE_MILLISECOND   (DELAY_ONE_MICROSECOND*1000)

}HANDLE_TABLE, *PHANDLE_TABLE;

	ULONG HighWaterNumberOfHandles;
    //後面暫時用不到，省略
}OBJECT_TYPE, *POBJECT_TYPE;
