Because sometimes desk jockeys within the IT world put on their blue collar, settle for a mediocre salary, grow 4-6 pant sizes, and think "this is good enough"

Up until new blood walks up, points out a flaw, and fucks shit up because the "senior" desk jockey can barely squirm out of his $1000 computer chair to reach his keyboard.

That's just my take on it, if Lizard Squad states that it has taken them minimal effort to setup these attacks; then what's stopping a larger organization from doing such things?
