Dr. Richard Browne:

The initial access was via the single device. Once the individual device was affected, that could have been caught, not that it necessarily would have been. In and of itself, that is not the end of the world. However, it should have been caught and the PwC report from December of last year makes the migration of the actor across the network very clear. There were multiple signals that should have been caught. People did find these signals so it was known that there was activity but not action was taken. That is the fundamental challenge.
