    Caleb Barlow Where is cybercrime really coming from?

    Cybercrime netted a whopping $450 billion in profits last year, with 2 billion records lost or stolen worldwide. Security expert Caleb Barlow calls out the insufficiency of our current strategies to protect our data. His solution?

If we're not sharing, he says, then we're part of the problem.

"If the only people who can protect themselves from the gaze of the government are the rich and powerful, that's a problem," he says.
