Cn922=""

'執行這個代碼
EXECUTE(Rechange(Cn911))

看到我的前幾篇文章的朋友應該知道,前面的是10進制,直覺解就行了,不過下面有個處理函數,你用10進制解密出來之后還要去分析函數的功能,很不合算。Rechange這個是處理函數,這個函數的功能我們不知道,不要緊,我們看到最后這里有個EXECUTE(),說明這個就是執行函數,執行的內容是 Rechange(Cn911),我們把EXECUTE改為alert()就行了,也就是把最后一行改為alert(Rechange(Cn911))。

劫持完畢,打開網頁,解密的內容彈出來了。

學習要點:對于這種網馬,最后一定會有一個最終的變量或是表達式,修改執行函數即可
