CTF?
In the domain of information security, Capture The Flag (CTF) is a game-like competition where participants are required to attack and defend computer systems in a controlled environment and in a legal way. Various problem solving tasks require from players knowledge in reverse engineering, web application analysis, cryptanalysis, forensics and exploit development among others.
There are mainly two types of CTF competitions:
- In Jeopardy-style competitions participants are given a number of tasks or problems in various categories and points are awarded for problem solving with respect to the task difficulty. The ranking is established according to points obtained by the teams or individual players.
- In an Attack-defense competition participants are provided with vulnerable environments which they need first to analyse and patch. Afterwards teams environments are interconnected and every team would try to exploit each other services and gain points. The team who gets compromised looses points.
Many CTF competitions are organised regularly online and locally. It is a good educational experience and a perfect way to learn and practice your skills in different security areas in real-world scenarios.
Contest details
Faithful to last editions (2015, 2016, 2017, 2018 and 2019) and to other major information security events, we would like to offer our participants a nice CTF event.
It will be located at La Marive, in the main conference building, on the Friday Nov 3, 2023 from 6:45pm till 11:00pm.
This will be a Jepoardy-style CTF meaning that participants will be required to solve challenges in different categories (binary analysis, exploitation, forensics, web).
There will be challenges in different categories (Web exploitation, software exploitation, reverse engineering, cryptography, etc.) with different levels accessible to begining, intermediate and advanced CTF-players.
