247CTF joined

We are happy to announce...
Another site has been put into the wechall rankings.

The site is https://247ctf.com/ which is brand new and makes a solid impression.

The author told us the following.

Quote from "two47CTF"

I enjoy playing CTF challenges, but often found that I was not available in
the short time period that the CTF was open (usually a weekend). I also
found that often times people would unintentionally (or intentionally)
break a challenge either during or after solving it. I also don't enjoy
enumeration during a CTF, I prefer a straight forward problem to which you
need to solve. As a solution to these frustrations, I created 247CTF which
is a CTF platform that does not have an end date, nor does it have
challenge sharing between different players (each challenge instance is
unique per user), nor is significant enumeration required.


I set a basescore of 10000 and we all wish you a
Happy Challenging!

New Site: Énigmes À Thématiques

Time to learn French if you don't know it already: a new site has joined. It's called Énigmes À Thématiques and has challenges in many topics. Get your vin, baguette and other stereotypes and throw them away because you don't have time for that nonsense with this many new challenges.

Bonne Énigmer!(?)

LordofSQLi joined

We are happy to announce...

A new site has joined and is scored now.

LordofSQLi is a new site from South Korea, created in summer 2018 and is focused on SQL injection.

The database systems to exploit vary; mysql, sqlite, mssql, mongodb, ... and there are also some web application firewalls to keep you entertained.

The currently 49 challenges are in english and the overall site seems slim and fast.

The author rubiya created the site to make developers more aware of SQL injections, but i assume he does also like exploits.

We wanna welcome the Lords with a...

Happy Challenging!

New Site: MysteryTwister

This time we are really happy to announce...

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...

Happy Challenging!

New Site: CTFS.ME

From the islands of Indonesia, please welcome: CTFS.ME

A site for anyone who is interested in learning about CTFs, with web exploitation, cryptos and binaries. Everyone can contribute challenges, assuming they pass their quality check, of course.

Happy Challenging!!

New Site: try to decrypt

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.

New Site: Hack The Box

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!

And, of course: Happy Challenging!
