Hacked mongoDB on Ubuntu, scraping application
I am using Ubuntu 16.04 for scraping with python-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, it only downloads data and stores it. Any advice on how to recover the data, or how to protect from further attacks?
