Two days ago, I had connected to my ClearDB test server with MySQL workbench. I had left this workbench open and when I had checked it today, there were two new schemas named "test_justin" and "test_vishnu". I promptly reset my connection and sure enough, they were gone.
I have since reset the username and password for my database (which should have been secure enough in the first place). My questions are:
Has anyone encountered this as a bug in MySQL workbench or ClearDB?
How would an attacker create a schema when even my user account does not have permissions to do so?
What are some safety precautions I should be taking to ensure my database is not compromised again?
