The FBI is all over this, I was coordinating between the agency and several of those first attacked, for a while, and am still in touch with the agency. There is also a private group of the C-level folks of those orgs that have been attacked, who are talking and sharing amongst themselves.
For anybody here who has been targeted, contact me offlist (firstname.lastname@example.org) if you would a) like to be put in touch with the agency contact who is dealing with this (which I highly recommend) and b) if you'd like an invitation to the private group.
I'm on digest, so won't see replies to the list very quickly.
