North Korean Cyber Footnote

The House Permanent Select Committee on Intelligence had hearings on the 10th of September about cyber threats to the U.S. [see http://intelligence.house.gov/hearing/world-wide-cyber-threats]  During the questions section, Admiral Rogers was responding to the issue of deterrence of North Korea from doing more attacks like Sony in the U.S.  The DNI had replied that they knew of no other incidents since that time, but the Director of NSA added that he knew of nothing in the U.S., but that he had observed North Korea doing other things in countries other than the U.S.  This was an open hearing and there were no follow-up questions or inquiries into what those other things and other countries might be.   At the very least, it shows they are keeping an eye on North Korea and keeping track of what they are doing in cyber attacks.
