Operating systems, computer security, languages theory, and even more! CSAW CTF 2012 Quals. Written by Nicolas Hureau. We deemed it was a good idea to have some content to open our blog, therefore we chose to put it online right after the Nuit du Hack 2012 CTF prequals which happened March 24-25th. After the Codegate where we finished at the 14th place and first French team, we were confident that we could achieve a similar ranking during the NdH2k12 prequals. Written by Franck Michea.

Operating systems, computer security, languages theory, and even more! CSAW CTF 2012 Quals. Olympic-CTF 2014: zpwn (200 points). Written by Remi Audebert. This exercise was based on an IBM s/390 ELF running on a remote server which listens on UDP port 31337. The first thing we did was to setup. At first sight, the binary seems to send the entire buffer sent by the client via UDP. After disassembling it, we saw that the buffer is hashed and compared to a constant value: if the hash is equal to. Then, we d...

EPITA Systems Laboratory - C!

https://www.lse.epita.fr/projects/c!.html

Is a programming language designed with system programming in mind and more specifically kernel programming. Is greatly inspired by C, but its syntax differs in a few key points in order to suppress a few ambiguities. Moreover it extends C with constructs which aims at simplifying system programming, such as syntactic sugar for often used constructs. C! Also adds object-oriented features. It enables us to focus on the frontend, and leaves machine code optimisation to tools that are proven reliable. AddPo...

EPITA Systems Laboratory - RATHAXES

https://lse.epita.fr/projects/rathaxes.html

Rathaxes is a language for code once, compile everywhere device drivers development. Basically, it means that the developper writes the behavior of the hardware once. It will then be turned into calls to the kernel API targeted by the compiler. Using an internal template library, the compiler is able to translate its generic representation into a OS specific code. The ability to extend this template library enables Rathaxes to provide a driver environment for any OS which has been implemented.
