I had a few from drops. I was fighting a Klingon ship in a space battle when I was told that I had just used both of them. I did not have them selected or my inventory box open. Not sure what they are good for.
These are used for one of the new events that is coming. They will normally only drop from the enemy's in the events, however they are doping unintentionally at the moment. This is already corrected. so they should be gone in the next patch to the Beta server.
Don't worry about holding on to them they wont stay in your inventory for long, as they degrade over time.
