There is a bit of a nasty mess brewing in Empire Space, so if you head over there, then check the Galnet News feed you will get hints at which systems something is going down in. I know it's a bit of a trek, but it may be worth it in the coming weeks.
If you want to fight now, then you only have pirates to combat. Buy yourself a ton of gold or palladium and head over to your nearest mining extraction point. You will soon rack up 100k for a couple of hours.
