“Uwu?” Writeup

Hello!!!!
I hope you guys are doing your best.
I wanna talk about just my little experience of ctf web challenge that how did I get flag.I don’t wanna waste your time.And sorry for my grammatical mistake. So let’s start.

First,The challenge description is below.

And I clicked the hint button and I got this “This challenge gets progressively harder the faster your internet is if you do it manually”

But I didn’t really get the hint.So I clicked the another hint and get this “https://riceteacatpanda.wtf/uwu".
When I visit the link and my reaction is like “what the fk!!!!!”. Yep,The whole page was full of Uwu uwu UWU words.Like this.

But I noticed that the urlbar was changed 4 or 5 times .
Then I open my burpsuite and intercept it.And Boomb!! I found all url.Look a pic below.

So I look respond of first url and I get so many uwu uwu uwu words.Then I search the flag format “rtcp” and still get nothing.

I searched another url respond and still nothing.And I searched,I searched and Boomb!!!. I found the flag in 4th url’s respond.

The flag is rtcp{uwu_,_1_f0und_y0u}.

This is so simple web challenge.

Thank for reading my writeup and I hope you like it:)

See you all guys
