一台裸奔在云服务器上的MongoDB
前几天在自己个人的一台腾讯云服务器上安装了MongoDB，当时着急用，就用的默认配置，端口是默认端口，也没设置密码，还把bind_ip 设置成 0.0.0.0（允许所有ip远程连接）😅，后来就把这事抛到脑后了，也因为经常用无线网卡上网，ip经常是动态的，云服务器的安全组就放开了所有的ip。
完全就是一台裸奔在云上的数据库 😭 😭 😭
被攻击
下午忙完工作，为了方便学习，把MongoDB里的几条主要数据（json）都备份成.json文件了，然后就去吃饭。吃饭回来MongoDB客户端连接失效，重连了一下MongoDB，建的库不见了，留下了一个新库：READ_ME_TO_RECOVER_YOUR_DATA，里面只有一张表：README：
不会被勒索了吧？还真是！数据库全部内容如下：

看MongoDB日志，有个日本东京的IP【18.179.34.199】刚好在我吃饭这几分钟连接了数据库：

就吃顿饭的功夫~ 呵呵呵呵呵~ 😓 😓 😓 幸亏劳资备份了，让黑客兄弟又少赚一千块。
网上一看，中招的还有不少，留言的模板还都是一毛一样的，被勒索的比特币从0.005到1个以上的都有。
在群里吐槽也被运维兄弟喷了😭
安全事故猛于虎
幸亏这次丢失的数据不多，也只是自己个人的测试数据，如果是公司的商用数据库数据，那被勒索多少BTC也得给啊 😁
这里给再次给自己也给大家提个醒，安全事故猛于虎，安全责任重于山。
一定不要为了图方便，就忽略某些安全配置，平时做什么都要有安全意识。
重要数据及时备份。
服务器设置IP黑白名单，关闭一切可以关闭的端口
如果跟我似的，访问服务的ip经常变，可以考虑修改一些服务的默认端口，增加被扫到的概率
一定要设置密码，为了防止被爆，最好是无规则的强密码
