Chris Buffa (Modojo): Sony, Nintendo, Bethesda, Codemasters and Sega have one thing in common, aside from publishing video games.
They were all hacked.
Turns out, the skilled hackers that crippled Sony's PlayStation Network inadvertently (perhaps intentionally) started a movement within the community, the desire to break into and therefore embarrass (perhaps financially damage) other companies. Some do it for kicks. Others, to obtain information illegally.
