@thorinklosowski.comReposted by @defcon.bsky.sociallast year we did a little made up holiday called Opt Out October that was all about taking control of your data across platforms. This year we decided to talk about how many excellent alternatives to the products made by big tech are out there www.eff.org/pages/welcom...

@xenokovah.bsky.socialReposted by @defcon.bsky.socialArbitrary 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!🤞🤝😊

@hillert.bsky.socialReposted by @defcon.bsky.socialThis #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…

@hillert.bsky.socialReposted by @defcon.bsky.socialOne 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!
@sdholden.bsky.socialReposted by @defcon.bsky.socialClifford 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
@defcon.bsky.socialFriendly 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.
@defcon.bsky.socialMore 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’.
Enjoy, and pass it on.
@defcon.bsky.socialFor 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.
