Hi! Sorry to keep you waiting!

Welcome to cheatquest of hxpschr!

We are haxorpsch0rr! But everyone calls us hxp.

This is what we call a “challenge.”

This world is widely determined by sleepless nights known as CTFs.

We haxors waste our time with challenges, sometimes we survive with the help of beer, sometimes we use tools like “IDA”.

And sometimes, after having experienced enough pain while solving other CTFers’ challenges, we band together and organize our own capture the flag.

But despite our huge time investments, we are not even close to understanding computers.

In fact, there are many, many secrets surrounding bits and bytes.

To unravel haxoring mysteries, we’ve been undertaking research. That’s what we do.


All right, are you ready?

Your very own adventure is about to unfold.

Take courage, and leap into the cheatquest of hxpschr where dramas, headaches, and frustration await!

Well, we’ll be expecting you later. Come solve this baby challenge and find the flag when you start your quest.

Note: Replace < and > by { and } before submitting your flag.
