Description:

Check the flag and if you enter correct flag, it will show you correct message.


Solution:

When we go to challenge site we see a web page that ask us to check a flag .

So now we need find a flag for check. so first we will check the page source code when we check the source we found a path. /flag.html

After going that path we found a web page that says us 

"You've come to the wrong place."

But when we check the source code of the page we find a cipher text. It was Base64 encrypted. When we decode it, we find another cipher text which was ROT47 encrypted. We decrypt that using CyberChef and found a flag.

When we checked the flag we finally found the flag.

flag: IHC_CTF{CH3CK_F149_ajkfdn}
