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!
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
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
Of course some of you have noticed that there was a lot of trouble with the website today.
The old hoster has fusioned with another hoster, and there is a complete mess now in their datacenters.
We took the oportunity, and moved wechall to my cheap vserver and also released WeChall4.
I installed latest WeChall4 + a database backup that is around 7 days old.
In case we get access to the old server any soon, i might re-install with a more recent database.,
It might be possible that your account got lost, or other changes / updates you made in the last 7 days
We are very sorry for that inconvinience, but hey, we are back ;)
WeChall4 was not really ready for a realease, but i hope we will find all the new bugs sooner or later
For some changelog, please look into the forum, there is some post about major changes.
Please report any error you encounter, i think there are still plenty.
All in all I hope you like the new site, and get familiar with the new look&feel soon.
I am happy to announce, that a new site is participating in the wechall rankings. HackBBS is a french site, with a quite large userbase.
It is using an external phpbb forum, to keep the challenge and forum stuff apart, as the eternal goal on the site is to break into the server.
The site offers currently 84 challenges from the usual categories, but seems focused on exploit/hacking challenges.
According to the Admin, you are encouraged and allowed to crack the server by all means
Of course, you should not interrupt the server from it`s normal operation.
Also there are some "shell" challenges available, and all (but one) of the exploit challenges are real and not simulated.
Of course, to get your own impression, you have to try the site out!
Many thanks go out to it`s Admin, Korigan for implementing the needed scripts,
as well as kev1 and harry41 for contacting the admin in a proper and private way.
I am happy to announce that a new site is participating and has been put into scoring now.
http://www.tools-and-design.com/ is a classic challenge site that currently offers 83 challenges, mostly focused on webhacking,
but you will also find extra sections for Logic, Programming and Cracking. Of course, some crypto and stegano is involved too.
I settled the basescore to 10,000 as i think all sites will get the 10k any soon (with one or two exceptions).
The site is integrated into a 3rd party software, and seems to have a few problems with usability. But that won`t stop a skilled player to solve the challenges there
- If you can`t get a challenge mark as solved, try to logout/login again. It seems that the first auto-login does not set all cookies, or there is another problem with the first auto-login.
- The username on the site seems case-sensitive. Keep that in mind when linking accounts
Last but not least i want to inform you that there have been problems with my email account on wechall.
It might be that some emails got lost due a spam-filter.
If you have sent me an email and i did not answer, please send the mail(s) again.
They currently offer around 80 challenges from the usual challenge categories and also "shell challenges" on 4 wargaming boxes
Beside that, they have a huge amount of users, a big download section, tutorials and links that should cover our beloved hobby very well.
While browsing i also spotted videos, podcasts and much more stuff to explore.
Many thanks to sykadul and Phreak for implementing the needed scripts.
Cobrutos challenge site listbrain.tk is now put into the rankings and is ready to get linked.
Cobruto is known to me from tbs, where he submitted at least one challenge and obviously learned a lot since that.
His Website looks solid and i can only assume there are some nice and unique challenges.
From today a very new challenge site is participating in the global ranking: Rosecode.
It offers math and programming challenges only, and new interesting problems shall be added frequently, so it is similar to project euler.
Most problems require you to code a bit to compute the correct answers, but knowledge of math is most often required to come up with an efficent algorithm that can solve a problem within reasonable time.
Many thanks go out to elasolova for writing the needed scripts, and i wish all others:
