 Hey guys, John Hammond here still looking at Pico CTF 2017 So the next challenge is called mystery box for 60 points in the miscellaneous category It says you found a mystery machine with a sticky note attached to it Oh, there's also a picture of the machine that you found. All right, so let's check check out this picture here And it's a peculiar little box just like they said a mystery box I've seen this thing before Maybe you have maybe you haven't I don't know. I like that's this little bit of history I think it's pretty cool. So let's go ahead and download this picture if you for whatever reason didn't know what this was That's okay You could go to Google images not Google emissives and you could kind of upload Whatever you particularly wanted to search for and Google would use that as your search key So I selected that picture on my file system and got it uploaded and Some interesting results Who would win know your meme Okay, I see some interesting stuff here. I do see enigma encryption machine There's some big attacks on Alan Turing here, and I hope I'm not Going to some aren't charted territory. It really gets your gears turning. I hope there's something naval about so the heads Try and point to this thing as well the sticky note if you take a look at it It explains there. Okay, we have some German words here and whatever looks like some kind of information So I'll let the cat out of the bag here. I'll open up the box This is the enigma machine. So enigma machine is a cryptographic computer and not so much computer but a machine that was used during World War two to send messages from Germany and it was created with a whole lot of intricacies and a lot of complexity so that a mere mortal a human would not be able to easily decrypt or understand the messages that were going through it So it has a plug board. It has rotors. It has a bunch of stuff That is particularly named After German pieces so this doesn't make a whole lot of sense to us, but that's okay We know they are just inputs to this machine that would spit out some kind of encryption So let's see what we can get a hands get our hands on if we just look for like a niggum machine online Looks like there are plenty of online tools to be able to do this The emulator over here I think I had the most success with if you launch enigma We have all of these same settings that we can tune and actually set to the the proper inputs. So Using the navy one as it said from the hand using this umka her waltz thing for letter B the Wall walls and lodge I guess isn't defined so we can leave that LoG for whatever that thing is Growns along is PPP Plaid Parliament opponent. Hey, that's kind of a funny Easter egg there and The sticker Brett maybe Defines, okay the plug board so H G will go to L and H will go to F cool So now we you type the message that we're trying to go through so PX QQ TAM Y Y D BC Okay, so now we have this string whatever that is Just put this as flag I'm gonna remove the spaces and it says oh, oh quite puzzling indeed. Ha, okay That must be the flag. Let's go ahead and try and submit that and see how we do Try and submit and we got it. All right cool challenge solved your up 60 points So interesting interesting challenge the enigma machine is kind of in some of those Weird esoteric capture the flag games But it is kind of an interesting cool tidbit of history if you wanted to read more about it learn more about it The imitation game is a kind of beautiful and awesome movie I cry every time about Alan Turing and the stuff in World War two so check that out if you haven't seen it before But I think it's really neat There are other pie enigma Utilities if you wanted to do some of the stuff in Python And we can track that down in the later video if we need to but it is it is like the enigma machine Emulated in Python. So if you want to check out that you certainly could keep that in mind if you see this stuff and capture the flag Cuz it is out there. It is it is kind of common Sweet. Thanks for watching guys Hey, I need to give a little shout out to the people that support me on patreon all of these individuals are the best Individual like every single one of them is simultaneously the best like 17 people are both all the best person 17 times so Hey $1 a month on page on will give you a special shout out just like this at the end of every video $5 a month will give you early access to everything that I record and create before it gets uploaded on YouTube because I typically record in bulk and Then let YouTube like gradually upload things.
