当我今天做一些Web维护时,我发现一个名为“dbboon”的根级别的GoDaddy主机帐户上有一个奇怪的新文件夹,里面有一个名为proxy.PHP的单个文件.它的代码如下所示,似乎是某种代理功能.
原文链接:https://www.f2er.com/php/131198.html我有点困扰,因为我没有把它放在那里.我google了所有这一切了解更多,但没有找到任何东西,除了代理文件也存储在pastebin.com:http://pastebin.com/PQsSPbCr
我打电话给GoDaddy,他们确认它属于他们,说它是由他们的高级主机组放在测试目的,但没有更多的信息.
我以为这真的很奇怪:为什么他们会把东西放在我的文件夹中,而不给我一个单挑,为什么他们需要这样做?
有人知道吗
