Facepunch Reverse Engineering Challenge

Version 1

What is it?

The FPREC is a week long challenge where you are provided with an executable to reverse engineer. There will be a goal, such as "access this website", or "decrypt this file". Hopefully, there'll be rewards.

How do I participate?

Post your name in this thread any time up until the start date (Wednesday the 7th). The time of this competition is UTC+0. It will end on Wednesday the 14th. It is currently:


How do I do it?

At some point near 12:00AM UTC+0 on Wednesday the 7th, I will post the executable and the goal of the competition. Your job is to reverse engineer the executable and figure out what it does and how to accomplish the goal. If you need resources or help, check out the Reverse Engineering thread.

How many winners?
There is only one winner. The winner has a choice of his prize from the list of prizes. Maybe prizes would carry over if we do this another week? I dunno.

[supersnail11]

But this won't be a challenge that can be completed with simple .NET reflector.

[Darkimmortal]

Count me in

[Doritos_Man]

I'm down for this.

[supersnail11]

Jesus christ, Soda. I didn't say we'll be reverse engineering things to get people's passwords. I could hide a random number in a file and tell people to find it, for all you know. Stop rating people dumb.

I have given up even responding to him, as was said in the other thread. It just continues a rather worthless argument. I will continue doing what I consider fun, as will I suspect most people here, unless he has a heck of a lot better arguments then what he has shown so far.

[olavst]

Sounds fun, im in.

[Simspelaaja]

I'm in.

[Zeh Matt]

I'm a masochist, bring it on.

[areolop]

One (1) Game on Steam of the winner's choice with a value equal to, or less then $20.00 USD. (Before tax).

Now i'm glad i'm not competing

[Phreebird]

You should post a warm up.

[supersnail11]

Warmup Time!

Easy little warmup task. Here's the exe: http://blogcake.x10.mx/RE-Warmup.exe (I have no idea why chrome says this is malicious but the tons of keyloggers I've downloaded aren't)

Just a simple program that outputs an md5 hash. Your goal: find the string that makes the hash.

This is not the competition. There is no prize.

[nekosune]

When we get the string, do we post, or pm you with it?

[Ehmmett]

I have no idea what I'm doing lol
