获取句柄的类型以及对应的ID序号
遍历所有进程下的所有句柄,以及对应句柄类型.
一丶简介
在有的时候.我们会需要对应句柄名字.以及句柄类型的名称. 以及它所对应的的ID. 因为每个系统不一样.所以每次都是不一样的. 有的时候我们就需要借助Pchunter等类似的 Ark工具查看句柄名字. 以及对应的类型.
二丶原理讲解
想要获取 指定进程下的所有句柄,以及句柄名字. 句柄类型.我们只需要几步即可.
1.使用未导出API ZwQuerySystemInformation 获取系统所有进程信息.
2.根据PID打开进程句柄.(可以跳过自己)
3.挂起进程(目的进程)
4.使用未导出函数 ZwQueryInfromationProcess获取目的进程句柄的总个数
5.使用句柄拷贝函数 将目的进程中的所有句柄拷贝到本进程中来.
6.使用未导出函数 NtQueryObject 的2号功能.获取句柄信息. (包括句柄名,句柄的序号);
原理其实不难.就是调用API的事情.这里记录一下.
三丶实战
1.获取导出函数以及变量赋值.
导出函数声明为函数指针
ZwSystemInformation
typedef NTSTATUS(WINAPI * PfnZwQuerySystemInformation)(
IN ULONG SysInfoClass,
IN OUT PVOID SystemInfroMation,
IN ULONG SystemInforMationLength,
OUT PULONG RetLen);
NtQueryObject
typedef enum _OBJECT_INFORMATION_CLASS {
ObjectBasicInformation = 0, //如果为1表示获取名字信息
ObjectTypeInformation = 2 //表示获取类型信息
} OBJECT_INFORMATION_CLASS;
//单独对象获取打开句柄的信息
typedef NTSTATUS(WINAPI * PfnZwQueryObject)(
_In_opt_ HANDLE Handle, //句柄
_In_ OBJECT_INFORMATION_CLASS ObjectInformationClass, //要获取的类型信息
PVOID ObjectInformation, //缓冲区 用户模式下使用 NtQueryObject
_In_ ULONG ObjectInformationLength, _Out_opt_ //缓冲区大小
PULONG ReturnLength);
根据类型,Buffer信息为以下结构
类型为2:
typedef struct _PUBLIC_OBJECT_TYPE_INFORMATION {
UNICODE_STRING TypeName;
ULONG TotalNumberOfHandles;
ULONG TotalNumberOfObjects;
WCHAR Unused1[8];
ULONG HighWaterNumberOfHandles;
ULONG HighWaterNumberOfObjects;
WCHAR Unused2[8];
ACCESS_MASK InvalidAttributes;
GENERIC_MAPPING GenericMapping;
ACCESS_MASK ValidAttributes;
BOOLEAN SecurityRequired;
BOOLEAN MaintainHandleCount;
USHORT MaintainTypeList;
POOL_TYPE PoolType;
ULONG DefaultPagedPoolCharge;
ULONG DefaultNonPagedPoolCharge;
BYTE Unknown2[16];
} PUBLIC_OBJECT_TYPE_INFORMATION, *PPUBLIC_OBJECT_TYPE_INFORMATION;
类型为0:
typedef struct _PUBLIC_OBJECT_BASIC_INFORMATION {
ULONG Attributes;
ACCESS_MASK GrantedAccess;
ULONG HandleCount;
ULONG PointerCount;
ULONG Reserved[10];
} PUBLIC_OBJECT_BASIC_INFORMATION, *PPUBLIC_OBJECT_BASIC_INFORMATION;
关于类型为2,主要注意这个结构体.这里面的成员 MaintainTypeList记录的就是句柄对应的需要. TypeName记录的就是句柄类型名称
ZwQueryInformationProcess
typedef NTSTATUS (WINAPI* PfnZwQueryInformationProcess)(
_In_ HANDLE ProcessHandle,
_In_ PROCESSINFOCLASS ProcessInformationClass, //根据类型信息获取不同的信息
_Out_ PVOID ProcessInformation,
_In_ ULONG ProcessInformationLength,
_Out_opt_ PULONG ReturnLength
);
获取未导出函数
PfnZwQueryInformationProcess ZwQueryInformationProcess = reinterpret_cast<PfnZwQueryInformationProcess>(g_PsOpt.MmGetAddress(TEXT("ntdll.dll"), "ZwQueryInformationProcess"));
//根据进程句柄获取名字信息.
PfnZwQueryObject g_NtQueryObject = reinterpret_cast<PfnZwQueryObject>(g_PsOpt.MmGetAddress(TEXT("ntdll.dll"), "NtQueryObject"));
PfnZwQuerySystemInformation ZwQuerySystemInformation = reinterpret_cast<PfnZwQuerySystemInformation>(g_PsOpt.MmGetAddress(TEXT("ntdll.dll"),"ZwQuerySystemInformation"));
//根据句柄获取文件名路径.
PfnNtQueryInformationFile ZwQueryInformationFile = reinterpret_cast<PfnNtQueryInformationFile>(g_PsOpt.MmGetAddress(TEXT("ntdll.dll"), "ZwQueryInformationFile"));
其中我是封装了一个类,类里面的提供了个方法叫做MmGetAddress.其实就是对loadlibrary + GetProAddress的封装. 因为导出函数都是在Ntdll中.
2.编程实战
根据上方所定义则可以进行遍历操作了.但是要说的一点就是.上方你看做伪代码即可. 因为成员需要用到的结构很多. 网上一搜一大堆. 我这里会把这些结构放到最下面. 现在只需要知道会用到即可.
伪核心代码:
hProcess = PsOpt.PsGetProcess(dwPid); // 根据PROCESS 读取.
PsOpt.PsSusPendProcess(dwPid);//挂起
ZwQueryInformationProcess(hProcess, ProcessHandleCount, &handlecount, sizeof(handlecount), NULL); //hc == 句柄个数
HANDLE hTarHandle;
for (DWORD64 i = 0; i < 400000; i+=4)
{
if (1 == DuplicateHandle(hProcess, (HANDLE)i, GetCurrentProcess(), &hTarHandle, 0, 0, DUPLICATE_SAME_ACCESS))
{
//使用NtQueryObject遍历这个句柄信息
ULONG uRetLength = 0;
char * Buffer = new char[0x100]();
OBJECT_INFORMATION_CLASS ob = ObjectTypeInformation;
g_NtQueryObject(hTarHandle, ob, Buffer, 0x100, &uRetLength);
PPUBLIC_OBJECT_TYPE_INFORMATION pBuffer = reinterpret_cast<PPUBLIC_OBJECT_TYPE_INFORMATION>(Buffer); //查询类型信息
printf("句柄名字为: %ws \t 句柄类型为: %d \t \r\n", pBuffer->TypeName.Buffer, pBuffer->MaintainTypeList);
}
代码讲解
1.根据PID获取hProcess(自己封装的)
2.根据PID挂起这个进程
3.ZwQueryInfromationProcess 传入类型为ProcessHandleCount (20) 遍历这个进程的所有句柄个数.其中传入的HandleCount就是句柄个数.
关于ProcessHandleCount是ZwQueryInformationProcess用的结构.会放到下面.
4.因为知道句柄个数.但是不知道哪个句柄有效.所有直接遍历.通过DupLicateHandle进行拷贝.拷贝成功的就是有效句柄.
5.拷贝成功的句柄使用NtQueryObject进行遍历.使用第二号功能.传出的结构是上方定义的 PUBLIC_OBJECT_TYPE_INFORMATION 然后转化依稀.
6.输出结构的句柄号.以及句柄名称.
ps: 因为是控制台可能有些没显示或者覆盖了.大概看看对不对即可.
pchunter查看.
可以看到.File类型的类型确实也是 36. 因为每个系统不一样.所以我们有时候特别需要这个序号.
而使用ZwQuerySystemInformation的时候是可以遍历全局句柄表的.并且得出它的EPROCESS以及 句柄类型. 那个没有写.自己调试看过.现在把这个记录一下.
3.用到的结构
用到的结构如下:
为了方便拷贝.不放.h文件了.直接将里面结构拷贝出来.改改即可.
这是用到所以临时写的.所以拷贝出来的结构很多用不到.可以删除.懒得删了.
