CTF in DEFCON 21 2013
DEFCON21 – one of the world-largest conferences of hackers – was held in Las Vegas from 2nd-4th August. About 15,000 attendees joined the event from different countries in the world seeking a place to present their research, get the latest information, and exchange their opinions.
DEFCON21 offers not only briefings, but also a variety of other opportunities such as hands-on experience of lock picking tools, sales of event items and spy tools, as well as events like the badge contest. Among all of these, the final of CTF (Capture The Flag) is probably the most prominent one.
