在写驱动搜索内核模块内存时,你是不是也经常会遇到BSOD?
原因是内核模块INIT节调用完成后就取消了映射。
解决这个问题鄙人的方法是,
自己来映射该内核模块文件内存进行内存操作。
我们使用ZwQuerySystemInformation遍历枚举模块,
得到模块名后使用ZwMapViewOfSection映射内存。
代码:
#define SEC_IMAGE 0x01000000
void* MapFileBaseAddress = NULL;
HANDLE hFile = NULL;
HANDLE hSection = NULL; /** 内存映射文件,返回基址:
*/
void* CreateMapFileAndGetBaseAddr(
PUNICODE_STRING pDriverName
) {
//HANDLE hFile;
//HANDLE hSection;
NTSTATUS status;
SIZE_T size = 0;
IO_STATUS_BLOCK io_status = {0};
OBJECT_ATTRIBUTES oa = {0}; InitializeObjectAttributes(
&oa,
pDriverName,
OBJ_CASE_INSENSITIVE,
0,
0
); status = ZwOpenFile(&hFile,
FILE_EXECUTE | SYNCHRONIZE,
&oa,
&io_status,
FILE_SHARE_READ,
FILE_SYNCHRONOUS_IO_NONALERT);
if(!NT_SUCCESS(status))
{
DbgPrint("ZwOpenFile failed\n");
return NULL;
}
oa.ObjectName = 0; status = ZwCreateSection(&hSection,
SECTION_ALL_ACCESS,
&oa,
0,
PAGE_EXECUTE,
SEC_IMAGE,
hFile);
if(!NT_SUCCESS(status))
{
DbgPrint("ZwCreateSection failed\n");
hFile = NULL;
ZwClose(hFile);
return NULL;
} status = ZwMapViewOfSection(hSection,
PsGetCurrentProcessId(),
&MapFileBaseAddress,
0,
1024,
0,
&size,
ViewShare,
MEM_TOP_DOWN,
PAGE_READWRITE);
if(!NT_SUCCESS(status))
{
DbgPrint("ZwMapViewOfSection failed\n");
hSection = NULL;
ZwClose(hSection);
hFile = NULL;
ZwClose(hFile);
return NULL;
}
return MapFileBaseAddress;
} 调用方法映射文件返回映射后基址, 代码: PVOID BaseAddress = NULL;
UNICODE_STRING driverName;
...... RtlInitUnicodeString( &driverName, L"\\??\\C:\\Documents and Settings\\Administrator\\桌面\\111.sys" );
BaseAddress = CreateMapFileAndGetBaseAddr(&driverName);
DbgPrint( "MapFile Return Address:%X\r\n", BaseAddress ); 释放清理: if( NULL != hFile )
ZwClose(hFile);
if( NULL != hSection )
ZwClose(hSection);
代码仅供参考!
PsGetCurrentProcessId()
也可以用NtCurrentProcess()代替。
以上代码在XPSP3 DDK下测试通过!*转载请注明来自看雪论坛@PEdiy.com
