EnigmaGroup joined

Good news everybody!

Another site has joined the wechall network, and this time it is a site which some of you players were waiting for.
EnigmaGroup has been founded in 2005 and has collected around 18000 active users and 180 challenges.
They are pretty well known among the challenge scene, and sometimes referred to as blackhats.
Rumors say their challenges are pretty good and realistic and it awaits you a collection of the traditional challenge site categories:
exploit, crackit, crypto, stegano, logic, math, java/script, and more.

It is noteful that their crew is running their own security and development company yet they still offer EnigmaGroup as a training playground as a hobby.

Many thanks go out to psychomarine, Ausome1 and aVoid for joining us and implementing the needed scripts.

We all wish you happy challenging!

I am happy to announce that joined the wechall network.
It's the first (South) Korean site that joined, and it currently offers 55 webhacking and exploit challenges.
The sites main language is korean, but mostly the challenge sourcecode and description seems to be in english, so all people can give it a try and show their exploit skills again. is around 2 years old and offers a unique and selfmade interface. It seems a bit buggy here and there and is still in developement, but personally i like the minimalistic approach.
Many thanks go out to oldzombie for writing the needed scripts.

To enter solutions to a challenge, please goto the "Auth" section of the website and try to enter the solution word or the md5sum of it.

Now all that's left to say is:
Happy Challenging!

Revolution Elite

I am happy to announce that,

Revolution Elite is now participating in the wechall rankings.
It is a real puzzle site, with all the classic categories, and currently offers 44 quite difficult challenges.

I only got time for a short review, and i could not manage to solve the very first riddles.
The challenges are grouped by "cases", which gave me the look and feel of a CSI Miama storyline.

Thanks go out to sabretooth for creating the site as well as the needed scripts.

So, if you love puzzles, sabre and me wish you
Happy Challenging!

SPOJ joined

I am happy to announce...
... that Santa got another late gift for us.

SPOJ (SPhere Online Judge) implemented the wechall scripts, and joined our network.

SPOJ differs from other participating sites, as you have to submit your code and it gets executed and tested for correctness on their servers.
You are offered 1995 programming challenges whereas 44 programming languages are currently supported.
It is available in 4 human languages: english, Polish, Brazilan/Portuguese and Viatnamese, but i sticked with the english for my first impression.

Many thanks go out to kopringo for implementing the needed scripts, and of course to the whole staff over at SPOJ.

You might wonder about the high score of SPOJ here. The current algorithms reflect the huge number of challenges this way, and we will see how well it works.

What now is left to say is
Merry Happy Challenging!

EDIT: Here is some explaination of the scoring on SPOJ itself:

Security Traps joined

I am happy to announce...
that Security Traps joined the wechall network.
It is a brand new site with a simple and nice design, created by Mawekl
and currently offers 12 challenges, mostly from the javascript and exploit category.
Additionally there are five small signup challenges, which you need to solve to register,
as well as some hidden "eastereggs" / bugs on the site itself which give points too.

The user interface on the site is available in polish and english, the challenges/code/ciphertext is presented in english.

I wish the site a good start and many users that try it out,
and everyone else

Happy Challenging!

WeChall4 Contest

Dear Challengers,

I am happy to announce ... the WeChall4 contest:

Meanwhile we have 52 challenges of, in my humple opinion, high quality (with maybe 1 or 2 exceptions).

All of them should be solveable, and the majority of them is pretty straight forward and also fun and educative.

I challenge you to beat them all!

The first two persons who are able to solve all the WeChall challenges, will win a WeChall T-shirt, autographed by myself, and in a design of your choice.

All fellow players who solve them all will win an email account on

I hope you like the idea, and i wish you good luck and

Happy Challenging!
