I found this article very interesting.
The suspected North Korea missile launch towards the United States this past 4th of July weekend may have come in the form of a computer virus. Starting July 4th and continuing throughout this Tuesday, various U.S. government websites were assaulted by a cyber attack.
But did North Korea really do it?
-The United States and South Korea were attacked; both countries are major enemies of North Korea.
-Internet addresses involved in the attack were traced back to North Korea.
-The assault was more sophisticated than assaults by individual internet hackers.
-Ironically, the cyber attacks began on Independence Day, the day North Korea was to have fired missiles at Hawaii.
A very interesting set of coincidences, I think.
