> Most likely, months after ponying up $10 million to a sophisticated international hacking group, Caesars Entertainment probably doesn't want to invite some of the world's best hackers to stay and meet at its flagship resort.

Most Def con visitors would be white hats so that would be a bit disingenious. I would expect most attendees to behave (reporting issues after finding one)

Especially considering they just got hacked, a few pentests would be good for their business.
