Hi I'm studying English hard for maybe 4 months
therefore, I would have many wrong sentences
anyway Let's see problem
Read mafiakid's story. Understand what he wish to convey. Hey but wait, he doesn't just let people get there easily. Try your luck.
http://139.59.61.220:23489/
you can see it at first time
this page shows your ip so you can guess, if you want to enter this website so you must have specific address
how to parse a ip address in php??
maybe this php server use X-Forwarded-For
php use your real ip address, if you don't have X-Forwarded-For header in your packet
but, if you add X-Forwarded-For header in your packet then php use X-Forwarded-For header
at first, I tried 127.0.0.1 because it is Loop back address but It was not right address in this site
and then, I tried ctf site's ip
I added X-Forwarded-For: 139.59.61.4 in my packet then server returned page
like this
It was very hard for me
I just read that article and translated in Korea
and then I did to copy and paste that article
so that article changed other words xiomara{pr3f3r_sm@rtw@y_th@n_h@rdw@y}
maybe this technique is steganography
* if you have any questions about this ctf problem or what I wrote wrong sentences please send me a message
* if you know that technique(maybe steganography) so please tell me about what it is
