The @x33fcon conference was once again a complete success! I wanted to share the slides and demo videos from the "Downgrading FIDO MFA With AI Slop" talk I gave on the second day (the next day after the pirate ship party... ugh). 😵‍💫 Slides: github.com/kgretzky/talks/tr… Feel free to reuse the images and demo videos from the talk in your own presentations. Extremely happy to have had a chance to hang out with old friends and meet new faces from the Evilginx community. See you most definitely next year in Gdynia! 💗 Doxing people from the pirate ship photo: Front: @bongoalex @BigM1ke_oNe @thenopcode Back: @Jean_Maes_1994 @TimMedin

/me sighs I said we were declining more giveaways, but I've made an exception and I've accepted 1 more. After this addition, NO MORE GIVEAWAYS will be accepted. Okay? New giveaway added to queue (this isn't the official giveaway yet, please don't spam the comment section) Our friends at @vulnlab_eu hooked us up with a 10 90 day vouchers to all of their Red Team labs. This includes (Full Lab access for 90 days (x10)) - Standalone machines (specific vulnerabilities) - Active Directory Chains (practice chaining stuff) - Advanced Red Team scenarios with 4 different difficulty settings ranging from easy, medium, hard, and insane. This lab is usually for full-blown Red Team's, it's pretty cool stuff. I think some people will love the chance to try out this virtual shooting range Thanks, smelly smellington
