I take full responsibility for my lack of efforts for securing my server. I took no precautions to secure my Database. But still I wanted to make everyone aware that my Postgres DB on Ubuntu 16.04 was Hacked. and hacker asked 0.15 Bitcoins be deposited in his account in order to restore the DB. Fortunately my application is still not in production and nothing Essential was lost.
But it does raise few important concerns in my mind and i want to know what kind of strategies and precautions I must take in order to protect my Postgres DB on Ubuntu 16.04 ?
So that such a thing does not happen when my app goes into production.

My expertise is not in database security, but I would start with this article: https://www.digitalocean.com/community/tutorials/how-to-secure-postgresql-on-an-ubuntu-vps
I am using Ubuntu 16.04 for scraping with scrapy, storing the data in MongoDB. Today I logged in and found this hack message.
I don’t understand how could this have hapenned. I log to DO through SSH on my personal computer and my application has no other way to interact with the Internet. Any advice on how to recover the data, or how to protect from further attacks?
