White Rabbit crackme!
 

Quote

 

This time I would like to introduce a small contest organized by me and Grant Willcox. I wrote a small crackme and he volunteered to sponsor the rewards. The first 3 solutions will be rewarded by books chosen by the winners.

The crackme is a 32bit PE file. It shouldn’t be too difficult, but I didn’t want to make it boring either, so it has few tricks.

Disclaimer: I am not an author of the graphics used in the application, such as ASCII arts, icons and others. I don’t claim any rights to them.

Rules:

You need to find the flag in format flag{...} and submit it ASAP to any of us as a DM on twitter (@hasherezade or @tekwizz123). After we announced that the contest is closed, we would like you to make a writeup explaining how did you solved it.

There will be an additional reward for the best writeup – so even if you was not the fastest, you still have a chance to get a book for free.

If you have any questions, you can write them as comments to this post and I will be answering them. I am not giving hints via private messages – I want the contest to be fair for everyone.

At the end I will publish my own writeup with a detailed explanation.

Mind the fact, that the crackme contains some small obfuscation and malware-like tricks, so it may be flagged by some of the AV systems as malicious. False positives are very common when it comes to crackmes – it can’t be helped, sorry! I recommend you to run it on a Virtual Machine.
