编程技术- 驱动开发：判断自身是否加载成功

推荐 原创

文章分类 游戏逆向 游戏开发 编程技术 加壳脱壳 阅读数 : 425 阅读时长 : 9分钟

在驱动开发中我们有时需要得到驱动自身是否被加载成功的状态，这个功能看似没啥用实际上在某些特殊场景中还是需要的，如下代码实现了判断当前驱动是否加载成功，如果加载成功, 则输出该驱动的详细路径信息。

 

该功能实现的核心函数是NtQuerySystemInformation这是一个微软未公开的函数，也没有文档化，不过我们仍然可以通过动态指针的方式调用到它，该函数可以查询到很多系统信息状态，首先需要定义一个指针。

typedef NTSTATUS( * NTQUERYSYSTEMINFORMATION)(
IN ULONG SystemInformationClass,
OUT PVOID   SystemInformation,
IN ULONG_PTR    SystemInformationLength,
OUT PULONG_PTR  ReturnLength OPTIONAL);

其次还需要一个SYSTEM_MODULE_INFORMATION该结构内可以得到模块入口信息模块名称等，调用NtQuerySystemInformation数据会被格式化为SYSTEM_MODULE_INFORMATION方便调用。

typedef struct _SYSTEM_MODULE_INFORMATION {
     HANDLE Section;
     PVOID MappedBase;
     PVOID Base;
     ULONG Size;
     ULONG Flags;
     USHORT LoadOrderIndex;
     USHORT InitOrderIndex;
     USHORT LoadCount;
     USHORT PathLength;
     CHAR ImageName[ 256 ];
} SYSTEM_MODULE_INFORMATION, * PSYSTEM_MODULE_INFORMATION;

最后是SYSTEM_INFORMATION_CLASS该结构同样是一个未文档化的结构体，本此代码中需要用到的枚举类型是SystemModuleInformation其他类型也放这里后期做参考用。

  • 1.通过MmGetSystemRoutineAddress得到动态的地址。
  • 2.动态调用m_NtQuerySystemInformation得到参数。
  • 3.判断自身是否被加载，如果是输出路径。
