 What's up YouTube? This is John Hammond and we're looking at the Treasure Challenge in the Michelinist category of the Boot to Root 2019 CTF. It says the passcode is buried under the flag. Can you find it? And we're given a file to download and we submit Boot to Root passcode. So we're looking for like, same thing that we did in ScatterMe, just kind of a passcode thing. Okay, good to know. I've downloaded this file already so we have it in our current directory here. We can go ahead and move into that and we've got it. So if I check out what Treasure is, it's an ASCII text file with lots of long lines, okay? Looks like a lot of forward slashes and probably base 64. So what I did was I redirected that or piped into base 64 and then redirected that to a file called something. And that error, base, bash, base 64. I'm sorry. But a little bit. So now we've got something and that is a Game Boy ROM, okay? So I tried to Google run Game Boy ROM on Linux because I wasn't entirely, I didn't know, right? I found this article here. That was the one that kind of popped up earlier when I was looking for how to play, excuse me, how to play the Nintendo Game Boy games on Linux. So they're referred to Visual Boy Advance. So you can just go ahead and copy and paste these, like that will go ahead and install Visual Boy Advance for you, man. I'm running out of video energy, apparently. So when you have downloaded Visual Boy Advance, you won't be able to tab out a complete to Visual Boy Advance, but you'll be able to run VBA. So VBA, looks like I would try and run something with VBA and it told me unknown file type something. So I'm assuming this needs a file extension. So what I went ahead and tried was just renaming something to something.gb, because I know that that is a Game Boy ROM file extension from my days of yonder, I guess. So now VBA something.gb will spin up this little guy. And I don't know if you can see it that well, but down to the very bottom there, maybe the thing that's moving is the flag or treasure or something. But that says 58DPY. So simple enough that might be the passcode, right? So let's boot to root that, boot to root 58DPY. And you can submit that and I have already done this because I just solved this. But that is that. That is the actual correct flag for the treasure challenge. So we could keep that in mind. Let's go ahead and paste it in there. Mark that challenge as complete. And maybe learn to think or two with ROMs that don't think it was a very too hard to base 6040 code that file, run file on it, ensure that it was a ROM, and then open it up with Visual Boy Advance on Linux.
