Hacked any thing means big loss of organization? And if our database hack then it will be serious consequences for an organization, including financial loss, damage to reputation, and loss of sensitive information.
MongoDB have big community so I think may be not possible to hack this but it's hack, In this article, we will discuss the very basic way in which a MongoDB database can be hacked, as well as how we can prevent this in simple way.
I have been using MongoDB in my application. First day I have create MongoDB database on my own server and added some testing data for testing purpose. Next day what I see there is no data available that was added yesterday. Just ignored because I think may be yesterday delete database by me or deleted data for testing purpose so added more testing data to database.
But Again next day again happen same thing NO DATA is available in my database.
I was not sure what exactly was going on. On initial research, I suspect that may be in background by mistake I have started some service and that is running and deleted my data from database so I have tried many thing like installing again MongoDB and starting and killing process of MongoDB, and again added some testing data. Because I think if background process is running it will be killed.
But that was not Solution.
What I can see in my database, The new database named READ_ME_TO_RECOVER_YOUR_DATA is there with this message:
All your data was backed up from your server. You need to email us at EmailName@email to recover your data. If you dont contact us we will reach the General Data Protection Regulation, GDPR,and notify them that you store user data in an open form that is not safe. Under the rules of the law, you face a heavy fine or arrest and your database dump will be deleted from our server forever!
I created the MongoDB server without authentication, and some hackers were able to steal/delete all of your data, and are probably now expecting you to pay some bitcoin to get it back.
I have uninstall the MongoDB and again installed with solid authentication.
