本菜鸟想想自己 做个进程管理工具,
ZwQuerySystemInformation 按网上一些教程 编译出来可以正常运行,
但是写成 dll文件 用其他程序调用就出问题
这是原始代码
#include <stdio.h>
#include <Windows.h>
typedef NTSTATUS (*ZWQUERYSYSTEMINFORMATION)
(
IN ULONG SystemInformationClass,
OUT PVOID SystemInformation,
IN ULONG Length,
OUT PULONG ReturnLength
);
typedef unsigned long DWORD;
typedef struct _SYSTEM_MODULE_INFORMATION_ENTRY
{
ULONG Unknow1;
ULONG Unknow2;
ULONG Unknow3;
ULONG Unknow4;
PVOID Base;
ULONG Size;
ULONG Flags;
USHORT Index;
USHORT NameLength;
USHORT LoadCount;
USHORT ModuleNameOffset;
char ImageName[256];
} SYSTEM_MODULE_INFORMATION_ENTRY, *PSYSTEM_MODULE_INFORMATION_ENTRY;
typedef struct _SYSTEM_MODULE_INFORMATION
{
ULONG Count;//内核中以加载的模块的个数
SYSTEM_MODULE_INFORMATION_ENTRY Module[1];
} SYSTEM_MODULE_INFORMATION, *PSYSTEM_MODULE_INFORMATION;
ZWQUERYSYSTEMINFORMATION ZwQuerySystemInformation;
BOOLEAN EnumKM(char *HighlightDrvName)
{
ULONG NeedSize, i, ModuleCount, HLed=0, BufferSize = 0x5000;
PVOID pBuffer = NULL;
PCHAR pDrvName = NULL;
NTSTATUS Result;
PSYSTEM_MODULE_INFORMATION pSystemModuleInformation;
do
{
//分配内存
pBuffer = malloc( BufferSize );
if( pBuffer == NULL )
return 0;
//查询模块信息
Result = ZwQuerySystemInformation( 11, pBuffer, BufferSize, &NeedSize );
if( Result == 0xC0000004L )
{
free( pBuffer );
BufferSize *= 2;
}
else if( Result<0 )
{
//查询失败则退出
free( pBuffer );
return 0;
}
}
while( Result == 0xC0000004L );
pSystemModuleInformation = (PSYSTEM_MODULE_INFORMATION)pBuffer;
//获得模块的总数量
ModuleCount = pSystemModuleInformation->Count;
//遍历所有的模块
for( i = 0; i < ModuleCount; i++ )
{
if((ULONG64)(pSystemModuleInformation->Module[i].Base) > (ULONG64)0x8000000000000000)
{
pDrvName = pSystemModuleInformation->Module[i].ImageName+pSystemModuleInformation->Module[i].ModuleNameOffset;
printf("0x%llx\t%s",(ULONG64)pSystemModuleInformation->Module[i].Base,pDrvName);
if( _stricmp(pDrvName,HighlightDrvName)==0 )
{
printf("\t\t<--------------------");
HLed=1;
}
printf("\n");
}
}
if(HLed==0)
printf("\n[%s] NOT FOUND!",HighlightDrvName);
free(pBuffer);
return 1;
}
int main()
{
ZwQuerySystemInformation=(ZWQUERYSYSTEMINFORMATION)GetProcAddress(LoadLibraryW(L"ntdll.dll"),"ZwQuerySystemInformation");
EnumKM("disk.sys");
getchar();
return 0;
}
这是导出 后的dll
#include <stdio.h>
#include <Windows.h>
#include <stdlib.h>
extern "C" __declspec(dllexport) BOOLEAN EnumKM(char *HighlightDrvName);//这句有问题 吗?
typedef NTSTATUS (*ZWQUERYSYSTEMINFORMATION)
(
IN ULONG SystemInformationClass,
OUT PVOID SystemInformation,
IN ULONG Length,
OUT PULONG ReturnLength
);
typedef unsigned long DWORD;
typedef struct _SYSTEM_MODULE_INFORMATION_ENTRY
{
ULONG Unknow1;
ULONG Unknow2;
ULONG Unknow3;
ULONG Unknow4;
PVOID Base;
ULONG Size;
ULONG Flags;
USHORT Index;
USHORT NameLength;
USHORT LoadCount;
USHORT ModuleNameOffset;
char ImageName[256];
} SYSTEM_MODULE_INFORMATION_ENTRY, *PSYSTEM_MODULE_INFORMATION_ENTRY;
typedef struct _SYSTEM_MODULE_INFORMATION
{
ULONG Count;//内核中以加载的模块的个数
SYSTEM_MODULE_INFORMATION_ENTRY Module[1];
} SYSTEM_MODULE_INFORMATION, *PSYSTEM_MODULE_INFORMATION;
ZWQUERYSYSTEMINFORMATION ZwQuerySystemInformation;
BOOLEAN EnumKM(char *HighlightDrvName)
{
ULONG NeedSize, i, ModuleCount, HLed=0, BufferSize = 0x5000;
PVOID pBuffer = NULL;
PCHAR pDrvName = NULL;
NTSTATUS Result;
PSYSTEM_MODULE_INFORMATION pSystemModuleInformation;
ZwQuerySystemInformation=(ZWQUERYSYSTEMINFORMATION)GetProcAddress(LoadLibraryW(L"ntdll.dll"),"ZwQuerySystemInformation");
do
{
//分配内存
pBuffer = malloc( BufferSize );
if( pBuffer == NULL )
return 0;
//查询模块信息
Result = ZwQuerySystemInformation( 11, pBuffer, BufferSize, &NeedSize );
if( Result == 0xC0000004L )
{
free( pBuffer );
BufferSize *= 2;
}
else if( Result<0 )
{
//查询失败则退出
free( pBuffer );
return 0;
}
}
while( Result == 0xC0000004L );
pSystemModuleInformation = (PSYSTEM_MODULE_INFORMATION)pBuffer;
//获得模块的总数量
ModuleCount = pSystemModuleInformation->Count;
//遍历所有的模块
for( i = 0; i < ModuleCount; i++ )
{
if((ULONG64)(pSystemModuleInformation->Module[i].Base) > (ULONG64)0x8000000000000000)
{
pDrvName = pSystemModuleInformation->Module[i].ImageName+pSystemModuleInformation->Module[i].ModuleNameOffset;
printf("0x%llx\t%s",(ULONG64)pSystemModuleInformation->Module[i].Base,pDrvName);
if( _stricmp(pDrvName,HighlightDrvName)==0 )
{
printf("\t\t<--------------------");
HLed=1;
}
printf("\n");
}
}
if(HLed==0)
printf("\n[%s] NOT FOUND!",HighlightDrvName);
free(pBuffer);
return 1;
}
这是调用 Dll 的 EXE
#include <stdio.h>
#include <Windows.h>
int main()
{
typedef BOOLEAN EKM(char*);
HMODULE hdll=LoadLibrary(L"testdll.dll");
if(hdll==NULL)
{
printf("载入模块失败\n");
}
EKM* EnumKM=(EKM*)GetProcAddress(hdll,"EnumKM");
if(EnumKM==NULL)
{
printf("定位符合失败\n");
}
EnumKM("disk.sys\n");
}
