 What's up, everybody? John Hammond here again and bringing you more content from the LASA CTF capital flag competition. Next challenge I was looking at was easy symbols, and the prompt here was force, course, horse, norse, orst, horse. What does this mean? The flag was not in LASA CTF format. I have already solved this challenge, but I just want to demonstrate how I did it. I got this easy text file, and I stored that in a easy symbols folder in my LASA CTF folder and just save that there. I can replace what I have and a sublime text, I opened it up, took a look at it, and went over to that folder, and it was easy text, and now just get this ampersand and exclamation point stuff. And I was wondering what this was. I looked at it, and I was like, okay, are these logical operators? Is this some sort of esoteric programming language? It's supposed to be able to translate this into like ASCII characters or something. I looked at these, and I literally googled for a while, like programming languages, with like ampersands, exclamation points, et cetera, et cetera. I never really got anything and didn't particularly know what programming language, programming language, actually do this. So I tried to look around if these were like logical operators. I couldn't do this in Python since it doesn't really like those operators if they were logical operators, but that would make no sense to see something like an ampersand, ampersand, ampersand. I've never seen that, or like a exclamation point, exclamation point. It's not like it's not, not, not. Would this be like resulting in a Boolean? Would it result in zeros and ones that I would put together like a binary value? And then just create a number or a letter? I didn't know. So I just kept poking around, took me maybe five minutes or so until I actually looked again at the hint. If I took a look at, well, let's say, the flag shouldn't have spaces. Okay, well, that didn't help. But then I actually just looked at force, course, horse, norse, source, and course. I was wondering what that meant, if it had anything to actually do with it. So I went ahead and googled that and then I looked at, oh, rhyme forces. Okay, rhyming, course, rhyming, source, course, blah, blah, blah. And then I saw Morse. I saw right in the rhyme zone. Oh, yeah. All of this stuff rhymes with Morse, Morse code, of course. That makes sense. So I took up a Morse to plain text converter. I don't have any code written for this, but I figured, OK, I can just use something online. That doesn't really matter. And I tried to look for one like back and forth. I'm trying to find the one that I had used earlier. Oh, yeah, I used this one. And I converted the text to Morse code to text. And it was just a matter of putting this easy text into something that was actual Morse code. Because normally, if I try to put this in, it's supposed to be like a dot slash. That's the way they expected it. So, yeah, see, that would output to question marks. They don't know what it is. So what I did is I opened up idle and just took the string, all of this stuff. And what I did is I replaced all of the like ampersands with a dot like it should. And I replaced all of the exclamation points with a dash. And I got this and I figured, OK, this might be the Morse code that it's asking for. Tried that and got nothing. Oh, oops, oopsies. At least something that didn't look like a flag. So I tried to submit that and it didn't work. So then I went back and figured, well, I just have to most have these in the wrong order. I'll just have to replace the current string that I'm working with to something else. If we could just replace the ampersand with the exclamation point and the ampersands with the ampersand. It's like flipping them because you just had to choose whether what represented what. And this made more sense. I knew I saw more dashes and most Morse code stuff in period. So I put that in and now I have Morse was cool. That's obviously the flag. I went ahead and submitted that and got us a 20 point point. So, yeah, easy enough, real simple. Again, Morse code, you just kind of figured out into Cypher for a little bit, which I was able to get done. So thanks for watching, guys. Easy stuff. See you in the next video.
