寻找PspCidTable：
SIZE_T FindCidTable()
{
SIZE_T CidTableAddr = 0;
UNICODE_STRING ustPsFuncName;
RtlInitUnicodeString(&ustPsFuncName, L"PsLookupProcessByProcessId");
PUCHAR startAddr = (PUCHAR)MmGetSystemRoutineAddress(&ustPsFuncName);
//DbgPrint("startAddr:0x%02X,startAddr+1:0x%02X\n", *startAddr, *(startAddr+1));
for (ULONG64 i = 0; i < 100; i++)
{
if (*(startAddr + i) == 0x48 &&
*(startAddr + i + 1) == 0x8b &&
*(startAddr + i + 2) == 0x0d)
{
CidTableAddr = (SIZE_T)(*(PULONG)(startAddr + i + 3) + (startAddr + i + 3 + 4)) & 0xFFFFFFFEFFFFFFFF;
DbgPrint("CidTableAddr:%p\n", CidTableAddr);
break;
}
}
return CidTableAddr;
}相关结构：
原32位结构：
typedef struct _HANDLE_TABLE
{
ULONG TableCode;
PEPROCESS QuotaProcess;
PVOID UniqueProcessId;
EX_PUSH_LOCK HandleLock;
LIST_ENTRY HandleTableList;
EX_PUSH_LOCK HandleContentionEvent;
PHANDLE_TRACE_DEBUG_INFO DebugInfo;
LONG ExtraInfoPages;
ULONG Flags;
ULONG StrictFIFO: 1;
LONG FirstFreeHandle;
PHANDLE_TABLE_ENTRY LastFreeHandleEntry;
LONG HandleCount;
ULONG NextHandleNeedingPool;
} HANDLE_TABLE, *PHANDLE_TABLE;
现在x64结构：
typedef struct _HANDLE_TABLE
{
ULONG64 TableCode;
PEPROCESS QuotaProcess;
PVOID UniqueProcessId;
EX_PUSH_LOCK HandleLock;
LIST_ENTRY HandleTableList;
EX_PUSH_LOCK HandleContentionEvent;
PHANDLE_TRACE_DEBUG_INFO DebugInfo;
LONG ExtraInfoPages;
ULONG Flags;
//ULONG StrictFIFO : 1;
LONG64 FirstFreeHandle;
PHANDLE_TABLE_ENTRY LastFreeHandleEntry;
LONG HandleCount;
ULONG NextHandleNeedingPool;
} HANDLE_TABLE, *PHANDLE_TABLE;
32位和64位结构体有点差别，注意LONG64 FirstFreeHandle;
