After two successful events in China, we've been looking for more places to share our hacker spirit with the world. First up we will be dipping our cyber toe in Bahrain by taking part in the Arab International Cybersecurity Conference (AICS) and Exhibition November 5 and 6, 2025. We'll be bringing a sampling of our villages, workshops and contests so there's something for everyone. The conference is held in the cutting-edge Exhibition World Bahrain facility and everyone attending the AICS can take part in all of the DEF CON offerings for free. Bonus: in an international first, we’ll also be offering exclusive DEF CON 2-day Training classes on November 3-4. Sharpen your skills with some hands-on, world-class instruction and maximize your DEF CON experience. More info on the trainings at training.defcon.org. We're excited to share the DEF CON experience with a brand new audience, so please save the dates. We'll have more information soon - watch for the updates! image

If you’re an avid docket watcher, you may have noticed that we filed a motion for summary judgement in Chris Hadnagy’s defamation suit against DEF CON . Summary judgement was granted with prejudice May 11, seemingly closing the case. To our surprise, Hadnagy filed an appeal in June. Then, less than 2 weeks later, he filed for a dismissal of that appeal. We accepted it. It’s time for an update! The complete dismissal of his defamation case was yet another moment where Chris was pursued by an opportunity for personal growth. Again, Chris was too fast. Instead, he filed an appeal. We may never know exactly why he thought this might be a winning strategy, but he did release a confusing LinkedIn video where he blamed his lawyers. He was never going to win. After a dismissal like this you can’t introduce new facts or arguments, only argue that the law was misapplied. The mistakes were made by Chris, not his lawyers. Every time, and by his own sworn testimony. There were many points in this saga where Chris could have chosen a different adventure, but did not. Now it is game over for him, and we are excited to return our full attention to moving on. See you soon in Las Vegas! #defcon #defcon33 #defconlegalupdate image
