I've seen some previous posts on this topic, but haven't come across a solution just yet.
In our 3.1.0 instance I was able to create an object called "Kill Chain" (edited the "create_object_types.py" to add a new object), then ran manage.py create_object_types to add it. With that we've been able to assign a kill chain phase (if known) to indicators.
Looking at the stable_4 instance I'm building I haven't seen anything that I could map this current information to. Has anyone else come across this challenge and, if so, what did you do to solve this?
Thanks!
