 Hey, what's up everybody? John Hammond again bringing you more content regarding the Elastus CTF high school CTF going on Next problem. I was looking at was the 404 challenge, which looks like a simple web challenge We were trying to make an introductory web problem that messed up somewhere along the way and there is a link here So I looked at this and I got a 404 not found looks like a pretty regular engine X Engine X, you know like default 404 not found page. So I was wondering, okay Is this at index.ehp? Is this at index.html? I don't know. I just started to look at stuff I looked at index.php when I loaded that It says not found this requested URL is not found the server and that was weird to me because like obviously This looks like a different page than the other not found page So I tried like index.html. I got the same exact thing once this actually loads if it does okay Yeah, it's not found and I thought that was just weird I tried like another port I tried if there was something supposed to be in the same area and same like vicinity But no those weren't actually hosting anything. So I looked at web.lastestctf.com Blah blah blah. I actually wanted to just end map it to see if there was if it was running on an interesting port So look back at the problems and I actually I like went to the rules of last CTF to see if it was okay for me to End map them or if they think that I was like me attacking or brute forcing them So look at the rules that like literally control F for rules blah blah blah Don't try to break stuff and I look back to the challenge and I realized like this question mark stuff It says oh the server isn't broken. I promise, but I promise I won't promise the page isn't hiding something If only there was some way to look inside and I'm like oh very obvious I I didn't realize they had these hints here but I can I now I will know that there are these hints here and We can definitely just view the source of the web page with control Right-click control page source or control you on the keyboard and it says backup flag in case something breaks Last the CTF welcome weatherman. It's super easy. It literally just had to view the source of the web page So we'll submit that and get our points. So easy too easy. It's looking at the source. All right That's the process I went through but it was really just a matter of literally looking at the source of the web page Thanks for watching guys really simple solution probably nothing that interesting But I want to show off how we can get those 10 points. See you soon
