DEF CON 24 Hacking Conference



The following collective of awesome individuals helped us review CFP's for DEF CON 24. Some below worked strictly on the CFP review board for talks, and others on workshops, some on both. From March to June these volunteers spent hundreds of hours of their time to pick the best content for DEF CON. They deserve a great many thanks, a cold one, and loads of recognition for the hard work. Thank you for all the help, and we hope you enjoy the rest of your summer!

LosT enjoys learning as much as he can about as much as he can. He can usually be found around CON in the 1o57 room, mostly encouraging and sometimes distracting a ragged band of sleep-deprived attendees who are racing to complete the challenge.

While no one relishes the job of rejecting submissions, Nikita strives to make the experience more positive with personal feedback and alternative speaking opportunities.

Beyond the CFP, Nikita also works full-time on various behind-the-scenes administration and project management for DEF CON.
