The world has gotten a glimpse of hacker warfare this month, with the now-infamous breach of Sony’s security having sparked legitimate international tension. Many assume North Korea was behind the “Sony Hack,” due to the nation’s threats against the company’s action/comedy film The Interview. And, in recent weeks, North Korea has begun to experience its own problems with Internet connectivity. This, of course, appears to be some manner of retaliation, though no details or confirmation of this assumption have been made public. But while all of this has been going on, there was a second Sony hack that raises an issue closer to home for the general public: both Sony’s Playstation Network and Microsoft’s Xbox Live were attacked over the holidays, apparently by known hacker group Lizard Squad, who claimed responsibility.
