Yeah I did couple of things, freed the little girl from the exchange and killed the exchange boss (squidface, can't remember the name). But as far as I know the Red Eclipse attack on the Ebon Hawk only starts if your Rep with the exchange is high enough? I "healed" the plague guy in the refugee sector, I killed the gang in the refugee sector, serocco I think.
I'll have a look into it once I am back from work today.
Thanks.
