我要实现的目的，就是写入一段字节集数据到目标内存地址,但是这段代码蓝屏，就算不蓝屏也没法写入字节集。
HMODULE
Address
= 0x00000000; // 被写入的内存地址（一个跨进程模块地址）
BYTE
Buffer
[] = { 255,200,163,0,0,0,0,0,0,0,0,144,144,144 }; // 需要写入到内存的字节集数据（10进制）
WriteProcessByte(
Address
, Buffer
, sizeof(
Buffer
));
---------------------------方便大神观看的函数分割线---------------------------
NTSTATUS WriteProcessByte(PVOID Address, PVOID Buffer, ULONG BufferSize)
{
PAGED_CODE();
NTSTATUS Status = 0;
KIRQL irql = WPOFFx64();
PVOID HookCode = ExAllocatePool(NonPagedPool, 0x200);
RtlFillMemory(HookCode, 0x200, 0x90);
_try
{
RtlMoveMemory(HookCode, Buffer, BufferSize);
RtlMoveMemory(Address, HookCode, BufferSize);
}
_except(EXCEPTION_EXECUTE_HANDLER)
{
Status = GetExceptionCode();
}
if(Status != 0){
_try
{
RtlMoveMemory(HookCode, Buffer, BufferSize);
SafeCopyMemory(Address, HookCode, BufferSize);
}
_except(EXCEPTION_EXECUTE_HANDLER)
{
Status = GetExceptionCode();
}
}
WPONx64(irql);
return STATUS_SUCCESS;
}
---------------------------方便大神观看的函数分割线---------------------------
KIRQL WPOFFx64() {
KIRQL irql = KeRaiseIrqlToDpcLevel();
UINT64 cr0 = __readcr0();
cr0 &= 0xfffffffffffeffff;
__writecr0(cr0);
_disable();
return irql;
}
---------------------------方便大神观看的函数分割线---------------------------
void WPONx64(KIRQL irql) {
UINT64 cr0 = __readcr0();
cr0 |= 0x10000;
_enable();
__writecr0(cr0);
KeLowerIrql(irql);
}
