Re: "Remove all external access?"

I believe this was a co-ordinated attack from the inside, an inside job. Look at who was not attacked as well as who was. I don't believe this worm tunneled in through the firewall, it was already on the LAN. If the LAN was segmented then the worm would need seeding on each segment. It would need seeding at each hospital.

If this worm came from the Internet then members of the public would have been hit. Although I have seen this sort of worm before, we're not seeing this one on home computers and small businesses.
