that experts in the field of cryptography have joined the wechall network.
The new challenge site joining is MysteryTwister, which is part of the famous open-source project CrypTool, known amongst challengers.
CrypTool is an academic approach to teach the mathematics behind cryptography in an experimental manner by offering three offline e-learning programs (CT1, CT2, and JCT), the website CrypTool-Online, and the MysteryTwister crypto contest.
The puzzles on MTC3 are, of course, of cryptographic nature, and quite some of the problems are yet unsolved.
MTC3 has almost 9000 players from all around the world and the ciphertexts are presented in English and German. There is an active forum to discuss the problems in a non-spoiling, moderated manner.
Currently there are 260 challenges by more than 50 different authors, offering everything about crypto and computational number theory I can imagine -- from classical ciphers (Caesar, Vigenère, Hill, ...) to modern symmetric and asymmetric crypto (ORYX, AES, RSA, ECC, Lattice, homomorphic, DSA, ...).
So if you need a warmup or a fresh excourse in cryptography, this surely is a place to look at.
The site is scheduled with 10,000 basepoints, and the wechall score also includes old and inactive challenge sets.
The project lead Bernhard Esslinger is looking forward to your feedback and,maybe, a yet unsolved challenge to be cracked.
We all hope that many of you discover something new while trying out the
site and we wish you...
Another one for you challenge-site collection. Try to decrypt, as the name suggest, is focused on cryptography. Challenges provide you with a mechanism to encrypt chosen plaintexts, from which you have to recover the encryption method to decrypt the solution.
Another fairly new site has joined WeChall! With currently 26 machines available (and one more on the way) through a private network in addition to a bunch of other challenges, Hack The Box looks to be quite a challenge.
Many thanks to ch4p for making sure the site works optimally with ours!
Time for a brand new site. Hacker Gateway just opened its doors today/yesterday and has already joined WeChall. What more could you ask for? ;)
Quote from Juampi
Hacker Gateway is a modern, open-source site built by a computer scientist and veteran challenger from Argentina. The site is intended for hackers of all skill levels, and spans several challenge categories, including cryptography, steganography and web, with more to be added in the future. The challenges go from pretty easy to very hard, and subtle hints are given when appropriate so that they never feel unfair.
If you want to put your hacking skills to the test, Hacker Gateway is the site for you!
I'd say "Happy Challenging!" to that! (Gizmore makes me.)
The Spanish site World of Wargame as been in the "coming soon" section for quite some time, but finally it is soon!
Quote from hds
World of Wargame is a spanish wargame that was created back in 2009 to help spanish speakers begin with information security challenges and one of the few still running, it is aimed for starters so you can find challenges from very easy to medium difficulty.
We have seven categories distributed across 101 challenges:
- Basic cryptography
- A lot of steganography challenges
- Identification of images related to computers
- CAPTCHA cracking
- Web application security
- And miscellaneous
The wargame includes a shop where you can buy hints with points, a system to earn points when rating a challenge, a list of solutions from users (3.5k approximately), and digital "gifts" you can find on your profile page that are given while solving the problems.
