Black Hat begins
The Black Hat USA 2007 Briefings got underway this morning at Caesar's Palace in Las Vegas. Founder Jeff Moss opened the proceedings with a few brief remarks and statistics about the show. Officially, there are more than 4,000 attendees from more than 50 countries, Moss said, and that number would have been higher if Halvar Flake been admitted to the country instead of returned to Germany by immigration officials.
