由于我一般使用的虚拟内存, 有时我们需要获取到物理内存中的数据(也就是内存条中的真实数据), 按理说是很简单,打开物理内存,读取就可以了.但似乎没这么简单:
[cpp]
#include "windows.h"
//定义相应的变量类型，见ntddk.h
typedef LONG NTSTATUS;
#define NT_SUCCESS(Status)((NTSTATUS)(Status) >= 0)
#define STATUS_ACCESS_DENIED ((NTSTATUS)0xC0000022L)
typedef struct _UNICODE_STRING
{
USHORT Length;
USHORT MaximumLength;
PWSTR Buffer;
} UNICODE_STRING, *PUNICODE_STRING;
typedef enum _SECTION_INHERIT
{
ViewShare = 1,
ViewUnmap = 2
} SECTION_INHERIT, *PSECTION_INHERIT;
typedef struct _OBJECT_ATTRIBUTES
{
ULONG Length;
HANDLE RootDirectory;
PUNICODE_STRING ObjectName;
ULONG Attributes;
PVOID SecurityDescriptor;
PVOID SecurityQualityOfService;
} OBJECT_ATTRIBUTES, *POBJECT_ATTRIBUTES;
// Interesting functions in NTDLL
typedef NTSTATUS (WINAPI *ZwOpenSectionProc)
(
PHANDLE SectionHandle,
DWORD DesiredAccess,
POBJECT_ATTRIBUTES ObjectAttributes
);
typedef NTSTATUS (WINAPI *ZwMapViewOfSectionProc)
(
HANDLE SectionHandle,
HANDLE ProcessHandle,
PVOID *BaseAddress,
ULONG ZeroBits,
ULONG CommitSize,
PLARGE_INTEGER SectionOffset,
PULONG ViewSize,
SECTION_INHERIT InheritDisposition,
ULONG AllocationType,
ULONG Protect
);
typedef NTSTATUS (WINAPI *ZwUnmapViewOfSectionProc)
(
HANDLE ProcessHandle,
PVOID BaseAddress
);
typedef VOID (WINAPI *RtlInitUnicodeStringProc)
(
IN OUT PUNICODE_STRING DestinationString,
IN PCWSTR SourceString
);
class PhysicalMemory
{
public:
PhysicalMemory(DWORD dwDesiredAccess = SECTION_MAP_READ);
~PhysicalMemory();
HANDLE OpenPhysicalMemory(DWORD dwDesiredAccess = SECTION_MAP_READ);
