最近空间攻击活动有点恶化趋势，首先是一个客户被一个声称是俄罗斯黑客攻击勒索，通过一些黑客软件让服务器瘫痪，以下是空间商发来的部分邮件内容：

很杯具的是，这个客户域名被瞄上了，网站放去哪个空间，哪个空间就遭殃。或许大家会问这些所谓的黑客是怎么搞的呢？其实这些黑客攻击有很多种，例如他使用一些简单的软件，将你的首页在一秒钟内刷新个一万几千次，这样就足以把服务器搞崩溃。当然，除非你被人盯上，一般来说不会有这种情况出现。这个客户被那个所谓的俄罗斯黑客勒索5000美元。有什么办法吗？木有。屏蔽他的IP？人家IP一直在换。结果只能换域名。

但是一般来说，空间商在攻击这方面都是会做一定的防备措施的。踏踏实实搞网站做优化还是不会有什么问题的。最近发现GODADDY的空间还是比较安全。毕竟是全球最大型的空间商。但是最近有不止一两个咨询客户反映，服务器被攻击挂掉了，啥资料都没有，都是香港的。怎么办？没有怎么办，就是如果你自己没有备份，所有网站资料，邮件，订单全部消失掉。真是回到原点了。这就是售后服务。看来便宜小公司还是有风险的。

另外，在这里也提醒大家，不要盲目使用搜集器搜集邮箱地址乱发广告。不是所有人都只会当垃圾邮件删除掉就完事，会有机会惹到黑客把你网站黑掉（当然你可能觉得这机会低得可以去买个六合彩，但是现在这些黑客软件淘宝大把卖呀亲），更重要的是，被人向空间商投诉，是会直接封空间的！空间商可不管你是谁，封了再说。
