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:

  1. Has anyone encountered this as a bug in MySQL workbench or ClearDB?

  2. How would an attacker create a schema when even my user account does not have permissions to do so?

  3. What are some safety precautions I should be taking to ensure my database is not compromised again?

No worries my friend! Your database was not compromised.

The systems administrator had this problem as well this week. We found out after he cursed across the room! After sending a call to our hosting provider, Heroku, it turned out that they were doing a test on a selected amount of machines (most likely on their Cedar stack) and created test schemas as a result.
