I generally use 'threat intelligence' when I'm talking about a product packaged and sold by a dedicated commercial entity and 'information sharing' as something that happens between security teams at trusted parties without renumeration.

A lot of the people who are hacking on behalf of governments are doing so on a contract basis. And they also do other things. They will hack on behalf of spammers, and will just be hired for a specific job.

I have spent my career building and improving secure, trustworthy systems, and I am very proud to be working on security at Yahoo.

I think... all of the best public cryptographers in the world would agree that you can't really build back doors in crypto. That it's like drilling a hole in the windshield.

I'm a huge gadget freak. I look on CNet literally every day to see what new gizmos are out there. I love technology. I'm constantly e-mailing. I've got the iPhone.

You're going to start seeing open-source, self-executing contracts gradually improve over time. What the Internet did to publishing, blockchain will do to about 160 different industries. It's crazy.

Frankly, it's never really been replicated in the history of the Internet what Yahoo has done in the areas it's done it.

What does 'work' mean in this 21st, ultra-wired century, with its exploding new industries, low barriers to entry and endless possibilities? Is technology making our lives more flexible - or our days more endless?
