今天学会了如何察看SSDT里面的东西、修改里面的地址

简简单单，虽然不懂它的道理，就算会用了吧

哎，内核级的东西调着也费事

因为一个 extern 没写，我可怜的虚拟机，连续蓝屏了4次。

typedef struct _ServiceDescriptorTable {
 PVOID ServiceTableBase; 
 PVOID ServiceCounterTable;
 unsigned int NumberOfServices;  
 PVOID ParamTableBase; 
}*PServiceDescriptorTable;

extern PServiceDescriptorTable KeServiceDescriptorTable;

ULONG GetFunAddInSSDTNow(ULONG offset )
{
 ULONG funAdd;

funAdd = (unsigned int)KeServiceDescriptorTable->ServiceTableBase;
 funAdd = funAdd + offset;
 funAdd = *(int *)funAdd;

return funAdd;
}
