A big shoutout to @MakerFaireDACH and @AVM_DE for hosting and sponsoring a smart home challenge and let 10 people win in that! It is a quite expensive hobby, so thank you for the voucher!
Finally I also got the hands on the all new shiny @dc801 Badge. I really LOVE the kind of game style and how they implemented the hex editor into the game.. Hack the Planet!! :-)
Look, kids, there even was a time when nobody had to wear masks. And most of them survived! #defcon27
Thanks @ThinkstCanary for creating canarytokens.com - such a great tool :) #wwhf
Just released the write-up and a solver script for the DC28 DCZIA challenge. Thanks again @syntax976, @LunaSylumDancer and @DCZia505 for some great riddle evenings :) github.com/devBioS/DC28_D…
I was only aware of using good ol' DCC for that. This work from samy is kinda Multipass ;)
I made a Mifare Classic + GoogleAuth access control system. Feel free to contribute! github.com/devBioS/NFC_Ac…
@LunaSylumDancer and I are going to be doing a walk through of the @DCZia505 badge challenge live on twitch.tv/syntax976 at about 3pm EDT and I will probably play some music after. So come hang with us this afternoon! @devBioS @ftp_alun
While mum, dad and sis are working on the @DCZia505 challenge, the kids repurposed the badge as a Playmobil TV :D @defcon #badgelife
Made the @DCZia505 badge mobile and playing DOOM and it still hides the gems from me! At least I found the other Videos elsewhere :) #badgelife #DEFCONSafeMode
Leaving our Bluetooth wifi and NFC on at @defcon this year because we're feeling bold. #defcon28 #DEFCONSafeMode
Our #DEFCON201 @foldingathome Team is now in the top 1,000 Team Rankings! Thank you @thedarktangent from @defcon and others from contributing to the cause! Keep adding those GPU and CPU power to kick #COVID19 ass! Join the #DC201 Team 241960: stats.foldingathome.org/team/241960
Typical #COVID19 day: Morning: pentesting an app with custom memory injection Noon: trying to support the smallest in math homework Evening: help the bigger one learning latin vocabluary
Thank you for everyone participating in our @foldingathome Team(241960) to help bruteforce COVID-19. Here is our ranking and 10 ten users. Keep up the good work
