Arbitrary achievement unlocked! "Filling 2 pinboards with badges!"😄 Achieved after this year's @defcon.bsky.social, but I'm hoping that in the future I can also track this achievement via the accomplishments gamification mechanism at #OST2 with all these conferences sponsoring it!🤞🤝😊

This #AI talk by #BruceSchneier at @defcon.bsky.social was superb! The usage of LLMs to find loopholes in the tax code, our political institutions etc. was quite eye-opening. Our institutions have to adapt fast. I am a little concerned about that… www.youtube.com/watch?v=eEBv...

dnssecuritytxt census, Sep 7: 216 domains publish a security contact in DNS, net +20. New: one.com + 19 more group.one brands (incl. WP Rocket, Imagify), @defcon.bsky.social's defcon.social, Concordia Univ. of Edmonton, Skatteverket, Steno (legal tech). One TXT record: dnssecuritytxt.org

My @rfhackers.bsky.social talk at @defcon.bsky.social #DC34 about the WiFi Shuriken just got uploaded! If you missed it, you can watch it at youtu.be/PQaiwDhtJvc?...

One of the best technical talks I have ever seen—period. Cliff Stoll is killing it in “Stalking the Wily Hacker: 40 Years Later” at #DefCon34 @defcon.bsky.social. It totally made my day! www.youtube.com/watch?v=6560...

Clifford Stoll's @defcon.bsky.social 34 (2026) talk (titled: "Stalking the Wily Hacker - 40 years later") was awesome >> highly recommend >> easily in my Top Ten of all time (this was my 17th DEF CON) www.youtube.com/watch?v=6560... #so_happy_I_got_a_seat

Friendly Reminder: While supplies last, you can get the Baochip-enabled #DEFCON34 badge in the DC store. It's our best badge yet - a fully inspectable open source platform you can use as a security token long after you've played through the conference goodies. Shop.defcon.org.

More early release goodies for you! The live music, pictures, short videos and a bunch more content from DC34 are up on media.defcon.org. And in that spirit, here’s another talk - Bruce Schneier’s presentation ‘Hacking AI’. youtu.be/eEBv0STiYhI Enjoy, and pass it on. #defcon #defcon34

For your information: The fine folks of DCG Easton (PA) are running a live presentation RIGHT NOW called 'What we did on our hacker summer vacation' which will include their debrief of #defcon34. If you've got the time, show them some love. www.youtube.com/watch?v=MleD... #defcongroups #defcon

A fun (and accurate) snippet from DC34 Coverage at Japan's Asahi.com: www.asahi.com/articles/ASV... "..casual light clothes such as T-shirts and shorts, but there are also people who wear dinosaur costumes and clothes full of personality that look like handmade devices all over their bodies."

Come and relive my @defcon.bsky.social Main Stage set over on my Mixcloud! www.mixcloud.com/daemonchadea...

Let’s start the week with an early release talk from DEF CON 34 - this time it’s ‘ESP32 as a counter-surveillance platform’. The humble, reasonably-priced microcontroller and an emerging group of applications, are helping democratize counter-surveillance. youtu.be/PcK-TDmzshc #defcon #defcon34

The DC34 early release talks roll on with Bill Swearingen’s presentation on defeating facial recognition with a little strategically applied style. Confound the panopticon and keep the look crispy. Wins all around. youtu.be/WyPmt8CE5L4 #defcon34 #defcon #facialrecognition

My friends and I won a CTF! 🥳🥇 Had so much fun hanging out with the Lonely Hackers Club at @defcon.bsky.social Definitely coming back next year!

dropped a CD of my album at the @defcon.bsky.social sticker wall. finders keepers 🤘

Went to defcon, and the merch line was nuts! 😆 @defcon.bsky.social Met Jeff M. , Paul N. And Ada Wong what an event! Looking forward to next year.

As DEF CON came to an end I had the chance to talk about DCNextGen at closing ceremonies. If you have kids ages 8-18 bring them to our program next year! 💫💜 @defconnextgen.bsky.social @defcon.bsky.social #defcon #hacker #cybersecurity

Thank you again to our contestants and to @defcon.bsky.social for making it a great con all around! A new scenario is already being cooked up!

Wore my epic raccoon onesie to the DCNextGen party and was twinning with one of our volunteers 🦝 @defconnextgen.bsky.social @defcon.bsky.social #defcon #cybersecurity #hacker

New: In a major expansion of its work, @projectfranklin.bsky.social will pay cybersecurity firms to provide free monitoring and protection services to rural water utilities. I talked to organizer Jake Braun all about it at @defcon.bsky.social: www.cybersecuritydive.com/news/water-c...

The post @defcon.bsky.social blues don’t get a whole lot easier year to year. Especially when you’re dumb like me and rip yourself out to take the red eye home. Something something be happy it happened at all…

It’s not quite over- there is an afterparty. And it’s at the Liv in the extremely swanked out Fontainebleau. Your badge gets you admission and a free drink. Doors open at 10:30. See you there. #defcon #defcon34 #afterparty

DEF CON 34 is wrapping up, and it’s been another amazing year. Deep thanks to the peerless #defcon community, the staff and Goons who make this thing run, and to the creators who share their passions. We’re already thinking of ways to top this year. See you soon, everyone. #defcon #defcon34

Thanks @defcon.bsky.social ! See you next year! (Unless it's cancelled) 😇

I did not make it to @defcon.bsky.social this year but the badge is not just a gadget but it can encrypt data securely and Bunnie the designer claimed that it COULD possibly with the code efficient enough be on the edge of running a unix-based OS to: @wired.com www.wired.com/story/defcon...
