DEF CON 27, Recon Village - Seyfullah KILIÇ's 'OSINT Approach In Big Data' →
Thanks to Def Con 27 Volunteers, Videographers and Presenters for publishing their superlative conference videos via their YouTube Channel for all to see, enjoy and learn. A last minute substitution on stage (due to the unfortunate inability of the scheduled speaker to appear) proved to be a great change of pace during the conference; with a Q&A taking the place of a single speaker.
