MARC ROGERS:

Again, you can't rule that out either.

If you look at the way the malware was distributed throughout the network, how many machines it took down, how they were able to set up the edge of Sony's network to distribute Sony's own private data later on, when they turned some of their edge servers into BitTorrent servers, a P2P file-sharing system, that required a certain level of access.

Now, that access could have come from attackers who had been sitting in that network for many, many months. But that access could also have just as easily — perhaps even easier — have come from somebody inside it.

And when Dmitri says that the one film that didn't get released was this one, we don't know that. We don't know how many films Sony is working on. So we don't actually know how many films didn't get released. And, also, with respect to the messages that North Korea makes, having spent four and a bit years living in South Korea myself, I'll tell you, North Korea makes these kinds of threats all the time.

They're telling us constantly that they're going to obliterate us. If you do this, we will obliterate you. I think the number of their threats that have actually come true is actually quite the lower percentage, rather than the higher percentage.

And that's not to dismiss some of the atrocities that they have committed, which are absolutely terrible.
