PDFs? From BlackHat? (Score: 1) by email@example.com on 2015-08-12 22:04 (#H7CB) Um, and I the only one who doesn't want to open any of these? Re: PDFs? From BlackHat? (Score: 1) by firstname.lastname@example.org on 2015-08-13 09:40 (#H8PH) Not sure what your concern is? It's a widely advertised and public conference held in a big, Las Vegas hotel. These are PDFs. You're afraid that if you open one the NSA will beat your door down? These PDFs don't show you how to hack the White House, they discuss the state of security systems. Likely the NSA attended the conference. Happy reading.
