Yesterday I was at a civilian settlement scanning the satellites for goodies. Been there before a few times, for ages and never a problem. Yesterday I had scanned and re-logged several times when suddenly after one of the scans, several ships became hostile and opened fire on me. I was very lucky to escape as firstly I was far from alert not expecting it', and secondly I was in a D rated AspX, so not very fast.
I did notice however that the last scan reviled a 'Open Symmetric's Keys' was this the reason?
