Black Hat's in the books. Now the vibe shifts: DEF CON is where hacker culture takes over, and where theory meets practical exploitation. Today, 4:30 PM, Crypto & Privacy Village: Diptendu Kar on "Crypto Is Fine. The Code Is Not." Crypto failures rarely come from bad math, they come from the gap between cryptographic theory and secure implementation. This weekend, Bug Bounty Village, Saturday 2:30 PM: @insiderphd and @hackfidgetcube on "Slop Spotting." As AI reshapes how code gets written (and how bug reports get filed), the challenge shifts from finding bugs to finding the right ones. Their talk digs into using SAST rule generation to separate genuine risk from AI-generated noise. IoT Village, Saturday 3:15 PM: Katie's back solo with "Beyond Your Bookshelf: Hackable eReaders." Bring your Kindle. She might jailbreak it on the spot. See you in the villages.
