很久没有登陆的Mysql服务器被黑了

look

I have backed up all your databases. To recover them you must pay 0.01 BTC (Bitcoin) to this address: 13eWyQW4YB6ecJjZasXyVNH6eAns5ogjto . Backup List: xxx. After your payment email me at sqlrecover471@onionmail.org with your server IP (49.xx.xx.80) and transaction ID and you will get a download link to your backup. Emails without transaction ID and server IP will be ignored. 

:(

值得庆幸的是, 是测试数据，
