原本想写个监控所有进程的注册表添加的程序,但是在进行到快结束的时候,发现在我们平时的操作中注册表操作太多了,过多的报警,反而觉得不好.最终是列出所有进程列表,从控制台接受用户输入进程id来实现对进程及其子进程的注册表修改以及进程创建的监控.
该程序在用户层下Hook了ZwCreateProcessEx和ZwSetValueKey两个API,具体原理就不多说了,目标进程申请内存、代码释放、修改api入口、跳转实现hook.感兴趣的就看看吧..
原先想实现的自动监控的功能没有实现,不过大模块已经完成了,原理很简单,写起代码起来却是很烦躁,动一发牵全身,实在有点痛苦,不愿意再去改这改那了,或许交给希望了解的人去测试,效果会好些^_^,最后请原谅代码中出现的一些写得非常糟糕的地方,我真的是不敢再去看自己的代码了
测试方法:程序运行后,输入你想要监视的进程ID,这时该进程,以及该进程所创建的任何进程都将被监视,并且在其修改注册表的时候弹出对话框询问是否允许进行该次注册表修改操作,点'y'允许操作,否则拒绝操作. (刚刚修改了一下,可以查看进程id和名称,同时从控制台接受进程id的输入,从而对指定的进程监控)
