mongodb数据库被黑客删除数据的表现

时间：2022-01-14 01:58:59

前些日子看阿里云便宜，买了一个，安装了一个mongodb，自己连着做调试。
好久没用了，今天突然惊喜的发现被黑客登录了。没想到居然还有人靠这么低级的漏洞混饭吃。
被黑的表现如下：

> show dis
HOW_TO_RESTORE_mydb1  0.078GB
HOW_TO_RESTORE_mydb2  0.078GB
README                0.078GB
local                 0.078GB
mydb1                 0.453GB
mydb2                 0.453GB

其中mydb1的数据和mydb2的数据都被清空了。
从mongodb的直连地址来自美国（当然也有可能是用的美国服务器做的代理，但是事发之后并不能ping通那个ip，应该对方水平也并不高，可能真是用的自己的PC）：

删除数据库的时间是：4:27
其中HOW_TO_RESTORE_mydb1、HOW_TO_RESTORE_mydb2、README存储的是勒索信息。勒索信息如下：

> use HOW_TO_RESTORE_mydb1
switched to db HOW_TO_RESTORE_mydb1

    "Solution" : "Your database has been downloaded and backed up on our secured servers. To recover your lost data: Send 0.1 BTC to our Bitcoin address and contact us by email with your MongoDB server IP address and proof of payment."
}

解决方法大家都应该知道，设置密码，改端口，新建用户跑mongodb，只监听127.0.0.1，设置防火墙等。就不多说了。
