Win7 CreateRemoteThread 另类使用方法

同样的代码,在XP下面随便你怎么整,WIN7的话是相当纠结的,具体哪些错误就不解释了 ~~

 

gg点了二十多页,在韩国某大牛的博客上总算找到一点思路(虽然看不懂韩文,但代码还算勉强看得懂吧)

 

原来是要用动态调用ntdll.dll >>  NtCreateRemoteThreadEx ,于是over~~

 

说明:

1、InjectDll.exe   是注入DLL的EXE

2、dummy.dll       是一个普通DLL,加载后弹出MessageBox

 

下面是一个XP中远程线程注入DLL的代码,在WIN7 + OD调试的例子:

 

 

看看错误信息:

杯具了,接着看! 重新运行OD调试,bp CreateRemoteThread

 

 

看看CreateRemoteThread 中的几个参数:

 

 

上图重要标记的几个参数:

(1) svchost.exe (PID: 3184) 句柄

(2) kernel32.dll ! LoadLibarayA

(3) 在svchost中为C://Work//dummy.dll字符串所分配的首地址

 

进入CreateRemoteThread

我们发现,实际上是调用kernelbase >>  CreateRemoteThreadEx 函数。

 

(GG了这个DLL,原来是它是继VISTA/WIN7之后额外的DLL,负责协助Kernel32.dll的调用!)

 

那我们看看这个函数调用栈中的参数吧:

 

 

 

发现与kernel32.dll >>  CreateRemoteThread 参数一模一样!

 

OK ! 我们再继续跟进kernelbase.dll >>  CreateRemoteThreadEx

 

 

那我们看看这个函数调用栈中的参数吧:

OK,这算到底儿了,因为ntdll.dll >>  ZwCreateThreadEx 已经运行到了内核代码,我们的OD没办法再调试了!

 

于是请google sysenter吧!

 

特别说明,kernelbase.dll >> CreateRemoteThreadEx  是对 ntdll.dll >> ZwCreateThreadEx  的补充扩展!

 

那我们都得到这样的结果 :

 

 

ntdll.dll >>  ZwCreateThreadEx  是未公开的API,MSDN、GG也很难找到相关资料!

 

下面是看看这个结构体伪代码:

 

typedef DWORD (WINAPI *PFNTCREATETHREADEX)
( 
    PHANDLE                 ThreadHandle,	
    ACCESS_MASK             DesiredAccess,	
    LPVOID                  ObjectAttributes,	
    HANDLE                  ProcessHandle,	
    LPTHREAD_START_ROUTINE  lpStartAddress,	
    LPVOID                  lpParameter,	
    BOOL	                CreateSuspended,	
    DWORD                   dwStackSize,	
    DWORD                   dw1, 
    DWORD                   dw2, 
    LPVOID                  Unknown 
); 


 

 

OK ,那剩下的我们只需要重写CreateThreadEx 函数即可!

 

为了保证XP的兼容,所以需要判断一下OS版本,下面是完整的测试代码:
