Defcon is awesome. If you enjoyed those puzzles know that many security conferences have CTF /Puzzles like that. Please come to a few to explore the Defcon like experience on smaller local scales. I recommend the Chicago Thotcon.
Thotcon is great but it was moved to every other year. Blue Team Con, which is more for defenders, is good and every year, if you're on a noThotcon year.
Capture the Flag events have a wide array of puzzle types. A puzzle from a previous CTF I participated in was a large PCAP file with identical packets except each packet had 1 byte (8 bits) of information that was different. If you took all of the different bytes and put them together, they formed lat/long coordinates... which when graphed on a map showed a word (which was the flag). While it does require some very outside of the box thinking, the puzzle basically required the solver to write a script to extract the values and graph them (time constraints made hand drawing basically impossible).
@@hiTocopter there are a ton of remote CTFs hosted by random companies, sometimes with gift card prizes! Highly recommend if you like puzzles. Even if you don't know a ton about hacking you can learn a lot from them.
YOO I respect Luke so much. But I didn't even know he participated in DEFCON. Much less teaming up with the other guys I also have mad respect for. I'm starstruck
I saw the thumbnail and was like, Hey thats Luke! and thats Goblin Lord Thor! I did not know they knew eachother, but I am not really surprised eather. This event seems super fun to attend
As someone who has 0 coding knowledge or anything relating to it but absolutely loves puzzles this video was amazing. The pictures and sword puzzle was great!
The instant you sat ROT LEFT DROP LAST I knew what you were supposed to do. Glad to know that I'm not a big dumbass and maybe I could compete in something like this lmao.
Not going to lie. The only reason I clicked on this video was because Thor was in the thumbnail and I kinda knew about Def Con but I stayed for the whole vid because it was interesting as heck and you tell stories really well. Can't wait to see the video tomorrow!
7:55 Why not take identical RGB gear for both teams, one configured to only do blue (/-ish tones) and the other configured to only to red (/-dish tones)?
@@Lampe2020 He's saying it hurt their soul how they actually did it, not how you're proposing they should have done it. It hurts their soul cause it was obviously unbalanced.
@@carlosmspk I didn't really "propose" anything, I know that it was in the past and thus can't be changed anymore. I asked more rethorically, implying the question of "Why didn't they come up with that on their own?".
Crash and compile is so much fun to watch as the moderators are tasked with distracting the competitors. The funniest thing I have ever seen is one of the moderators was pregnant at the time and faked going into labor to fake a competitor out. The moderators can get creative!!! : ) You can compete remotely offsite on the Goldbug prize most years. I think you needed to be there last year as there were some puzzles that required you to be there to access the Crypto Village. Great achievement for your first DefCon. It is always great to see everyone's thought process to finish a puzzle. Over thinking it is the most common thing that everyone does. You can always watch most of the official talks later through the DefCon servers. They encourage you to participate when there and watch later.
Can you do a small explenation on how you submitted the solutions to the problems? I was messing with the folding one and wanted to see if I get the correct answer
You can divide the pdf image in rows and columns of pixels. The black pixel of the first row is where it start and the first black pixel of the last column is where it ends. Do tge same thing with the last row of image. Thats how I would done it.
You can create a matrix where columns rapresents the page and the rows are the pixels of the last column of each page. On the resulting matrix you can color with black every pixel that are between two black pixels of the last column of each page that represents the dogear.
its quite easy actually, pdf are rendered by the pdf reader so those lines are actually expressed as vector graphics. they are literally functions inside pdf file. taking those functions for each page with some math you can compute the intersection point of the line. store that as y value and page number as x value... plot the image with the final word. I dont know why would they even think to print the book out😂
I was about to go to a friend's shop to print it all out because it was going to cost like $100 to print all of the pages at the conference center. Glad we got to meet and hang out!
I had ZERO issues this defcon - but prior years rouge PRIs made my phone carrier change to companies I don't have and all calls last exactly to the second 15 minutes on the rogue PRIs (same as oracle world), and one year my android phone security descriptor got corrupt day -1 (2 days before) walking deep in a hallway at con ... had to reflash my phone .. no clue how or what, but it was soft bricked all of a sudden.
Ahh, was that a challenge my good friend? From now on, next DEFCON I will make it my mission to hack at least one phone (preferably Iphones) because ANDROID ON TOP
As a Vegas native, I can be delighted to tell you that week was by far not the hottest of the summer, and yes this is a hellish inferno we live in every summer. October-May is gorgeous though! Don't know why they host so many conventions during the summer.
when I saw the swords they seemed like words that were also fragments of other words. But I'm not sure I would have tried inserting them into the middle
