果然，要币，而且要的真特么人性化啊
1、告诉你，你被黑了
2、付币，恢复文件，不付，月末删除文件，，FBI那个下面再说
3、付完后联系方式
4、没有币，没关系，还给你提供几个购买币的渠道
其中有一条是让看一下FBI提供的建议，，
我建议大家遇到这种情况不要支付，据不完全可靠消息说：攻击者并没有留存受害者的文件，只是骗受害者去付钱，详细信息见下链接：
当然如果你的文件比较重要的话可以Try一下
当然如果你非常Rich的话也可以Try一下
当然FBI的建议下面的还是可以听取的
备份很重要
最差也要定期备、按时备，最好就是实时备份
这个云机器上主要的服务有MySQL、NGINX、ES和Redis且服务的端口全部是开放的
在上面的链接中也可以看到这是是
Redis引起的安全事故
下面链接是对此进行的详细说明：
可以看到，最好不要把Redis发布到公网上去
因为这样可以使攻击者通过Redis获取到服务器的最高权限
处理方法
建议重置系统，然后设置严谨的端口发布规则，建立完整备份体系
