朋友發來一套盜用過來的DISCUZ模板，但打開網站會彈出提示框：Sorry！xxx.com，然后自動跳轉到原開發者網站，通過搜索N次也沒有找到代碼寫在何處。沒辦法了，誰讓小明哥這樣樂于助人呢，瞧瞧吧^_^。

本地安裝DISCUZ，接著將模板文件架構好。輸入：http://localhost/portal.php，沒有任何提示，好小子估計沒判斷?localhost。好吧，換成：http://127.0.0.1/portal.php?試試，有了…

當我們單擊確定的時候，將自動跳到開發者網站，悲痛呀！不過這樣做就顯然給我們留下入口，JS有多少種提示框彈出方式？試試最簡單的Alert吧。于是搜索?alert，所有文件中，僥幸找到一個。

彈出源碼：alert(_0xb200[10])，好吧，改成：alert('test')，刷新網頁，哈哈~預期彈出：test，看來是找對地方了。

于是刪除他的條件判斷：

1	;if(obj[_0xb200[7]](_0xb200[8])==0||obj[_0xb200[7]](_0xb200[9])==0){}else{alert(_0xb200[10]);window[_0xb200[2]][_0xb200[0]]=_0xb200[11];};

在刷新網頁，發現沒任何彈窗和任何跳轉了，這樣就解決了問題，但如果也想像作者一樣保護自己的“版權”，可以這樣：

其中_0xb200[7]這樣的形式，很顯然是數組，看看開發者如何申明遍歷的吧，本文件中搜索：_0xb200，找到了：

我去，加密了！解密還是比較簡單，讓瀏覽器去做。于是小明哥在桌面新創建了?test.html?文件，寫道：

1 2 3 4 5 6

<script type="text/javascript"> ????var?_0xb200=["\x6C\x6F\x63\x61\x74\x69\x6F\x6E","\x72\x65\x70\x6C\x61\x63\x65","\x74\x6F\x70","\x68\x72\x65\x66","\x74\x6F\x4C\x6F\x77\x65\x72\x43\x61\x73\x65","\x73\x75\x62\x73\x74\x72","\x77\x77\x77\x2E","\x69\x6E\x64\x65\x78\x4F\x66","\x6C\x6F\x63\x61\x6C\x68\x6F\x73\x74","\x35\x69\x32\x33\x2E\x63\x6F\x6D","\x53\x6F\x72\x72\x79\x21\x20\x53\x69\x6E\x67\x63\x65\x72\x65\x2E\x4E\x65\x74","\x20\x68\x74\x74\x70\x3A\x2F\x2F\x77\x77\x77\x2E\x73\x69\x6E\x67\x63\x65\x72\x65\x2E\x6E\x65\x74"]; ????for(var?i =0; i < _0xb200.length; i++){ ????????alert(i +': '+ _0xb200[i]); ????} </script>

運行?test.html?試試吧，結果輸出：

0:?location

1:?replace

2:?top

3:?href

4:?toLowerCase

5:?substr

6:?www.

7:?indexOf

8:?localhost

9:5i23.com

10:Sorry!Singcere.Net

11:??http://www.singcere.net

好小子，首先獲得頁面?URL，然后用?indexOf?截取判斷，最后彈出消息和跳到指定網站！于是小明哥把數組下標為9的5i23.com修改為自己的網站URL，然后數組下標為11的目標網頁修改自己成網站，將計就計，哈哈！

好吧，先找個轉換工具把我們新的URL用十六進制加密，然后將百分號（%）替換成：\x

實戰：caobug.com（數組?9）

工具：http://www.55la.cn/UrlCrypt/

加密后：%63%61%6F%62%75%67%2E%63%6F%6D

替換后：\x63\x61\x6F\x62\x75\x67\x2E\x63\x6F\x6D

彈出信息也替換了（數組?10）：

侵權后跳轉到（數組?11）：

加密后：%77%77%77%2E%63%61%6F%62%75%67%2E%63%6F%6D（www.caobug.com）

替換后：\x20\x68\x74\x74\x70\x3A\x2F\x2F\x77\x77\x77\x2E\x63\x61\x6F\x62\x75\x67\x2E\x63\x6F\x6D（http://www.caobug.com）

其中，\x20\x68\x74\x74\x70\x3A\x2F\x2F?表示：http://，有的工具無法轉換，我們就自己添加上。

最終結果：

我們粘貼到?test.html，看下能否正常輸出我們加密的字符串。

哇塞，一次成功。我們到此就可以替換開發者提供的文件啦~

替換成：

var?_0xb200=["\x6C\x6F\x63\x61\x74\x69\x6F\x6E","\x72\x65\x70\x6C\x61\x63\x65","\x74\x6F\x70","\x68\x72\x65\x66","\x74\x6F\x4C\x6F\x77\x65\x72\x43\x61\x73\x65","\x73\x75\x62\x73\x74\x72","\x77\x77\x77\x2E","\x69\x6E\x64\x65\x78\x4F\x66","\x6C\x6F\x63\x61\x6C\x68\x6F\x73\x74","\x63\x61\x6F\x62\x75\x67\x2E\x63\x6F\x6D","\x53\x6F\x72\x72\x79\x21\x20\x43\x61\x6F\x62\x75\x67\x2E\x63\x6F\x6D","\x20\x68\x74\x74\x70\x3A\x2F\x2F\x77\x77\x77\x2E\x63\x61\x6F\x62\x75\x67\x2E\x63\x6F\x6D"];

最后成功了，我們使用?127.0.0.1?等其它域名訪問都會彈出提示框，然后跳到?caobug.com?網站。

到這里，問題就解決了，也實現了我們的想法。假期結束了，還沒睡夠呢~
