我正在使用winappdbg调试,创建一个事件处理程序,该程序在连接到调试器的进程上挂钩了createfile函数。我不能使用“循环”功能,因为这种方式调试器是无法停用的,所以我使用其他功能。在看看有多少createfile调用发生后,我试图获得cpu precent的进程,并且它们自动进行到0.我认为它是因为调试器,但不知道为什么winappdbg debug + api hooking + cpu precent

while True: hooked = [ ]

eventhandelerobject = hooking4.EventReciever() 
    debugger = Debug(eventhandelerobject,False)

    for procid in psutil.pids(): 
     if not whitelist5.inlist(procid): 
      print procid 
      try: 
       debugger.attach(procid) 
       hooked.append(procid) 
       print "Initialized!"+str(procid) 

       errorfile.write("Initialized!"+str(procid)) 

      except Exception as ex: 
       print ex 
       errorfile.write(str(ex)+str(procid))

我不太清楚,因为我从来没有试图让调试的进程的CPU使用率,但我怀疑这是因为当你尝试和衡量,已调试的进程暂停。通常当你的调试器接受控制时,被调试的过程就会被冻结,因此你总会看到0%的使用率。

如果是这样的话,解决方案相当复杂。你必须写两个脚本(或者一个脚本,但是要运行两次)。一个调试目标,收集所有进程ID和正在打开的文件。另一个并行测量CPU使用率。
