神祕的dbboon文件夾與我的godaddy帳戶上的proxy.php文件

Question

今天做一些網絡維護時，我注意到我的GoDaddy託管帳戶在名爲「dbboon」的根級別上有一個奇怪的新文件夾，裏面有一個文件，稱爲代理.PHP。它的代碼如下所示，似乎是某種代理功能。

我有點困擾，因爲我沒有把它放在那裏。我GOOGLE了所有這些瞭解更多，但沒有找到任何東西，除了代理文件碰巧也存儲在pastebin.com：http://pastebin.com/PQsSPbCr

我打電話給GoDaddy，他們證實它屬於他們，說這是由他們的高級主持小組出於測試目的，但沒有任何更多的信息。 我覺得這一切都很奇怪：爲什麼他們會在我的文件夾中放一些東西而沒有給我提醒，爲什麼他們需要做這樣的事情？

有人對此有所瞭解嗎？

Answer 1

它看起來像代碼測試到dbexternalsubscriber.secureserver.net的連接，並返回結果在某種類型的JSON輸出。它可以用作某種類型的連接測試儀。我聽說過關於GoDaddy託管的一些不如人意的事情，但除了聲譽之外，如果可以的話，我會刪除它。另外，請檢查您的.htaccess文件，以瞭解可能反映此代碼的任何更改。
