All the evidence leads me to believe that the great Sony Pictures hack of 2014 is far more likely to be the work of one disgruntled employee facing a pink slip.

I may be biased, but, as the director of security operations for DEF CON, the world’s largest hacker conference, and the principal security researcher for the world's leading mobile security company, Cloudflare, I think I am worth hearing out.
