ShellExecute简单流程

【求助】钩住了ZwCreateProcessEx,拦不住ShellExecute？
XP下SSDT钩住了ZwCreateProcessEx (2K下ZwCreateProcess),
点击打开的进程可以监控
拦不住程序中ShellExecute创建的进程。
已解决, 是可以拦住ShellExecute, 挥泪感谢各位大侠的提点!!
看到这个帖子的回复,感觉很温暖,谢谢!
下边是ShellExecute简单流程：
ShellExecute->ShellExecuteEx->ShellExecuteExA->ShellExecuteExW->ShellExecuteNormal->SHELL32!CShellExecute::ExecuteNormal->SHELL32!CShellExecute::_TryInvokeApplication->SHELL32!CShellExecute::_DoExecCommand->SHELL32!_SHCreateProcess->SHELL32!_imp__CreateProcessW
ShellExecute:

你逆向看看ShellExecute就知道了
|
|
|
特地亲自测试了一下， 对于XP SP3下只须ZwCreateProcessEx足以， 绝对能够拦住ShellExecute创建的进程
就用下面的代码来测试的  .386
.model flat, stdcall
option casemap:none
include windows.inc
include kernel32.inc
include shell32.inc
includelib kernel32.lib
includelib shell32.lib
.data
szFileName db "C:\WINDOWS\NOTEPAD.exe",0
szCmdline db "c:\boot.ini",0
.code
start:
push SW_SHOWNORMAL
push 0
push offset szFileName
push offset szCmdline
push 0
push 0
call ShellExecute
ret
end start  |

先帮楼主解决问题，再提学习意见
 尊重，都是一点一滴过来的，真没必要BS人
