DefCamp Capture the Flag (D-CTF) 2023

DefCamp Capture The Flag ( D-CTF) is one of oldest, most shattering and rebellious security CTF competitions in Central and Eastern Europe.

The most skilled hackers and IT geeks put their knowledge to the test and compete with the best CTF teams from all over the world to get in the top 10 and go on to win the overall D-CTF competition – or “die” trying.

There’s one important rule though: hack before getting hacked!

The qualification phase is traditional Jeopardy while the final hosted in Bucharest is Attack & Defence. 

What is a Capture the Flag (CTF) event?

Capture the Flag (CTF) is a computer security competition. CTF contests are usually designed to serve as an educational exercise to give participants experience in securing a machine, as well as conducting and reacting to the sort of attacks found in the real world.

Reverse-engineering, network sniffing, protocol analysis, system administration, programming, and cryptanalysis are all skills which have been required by prior CTF contests.

There are two main styles of capture the flag competitions: attack/defense and jeopardy. In an attack/defense style competition, each team is given a machine (or small network) to defend on an isolated network. Teams are scored on both their success in defending their assigned machine and on their success in attacking other team’s machines.

Depending on the nature of the particular CTF game, teams may either be attempting to take an opponent’s flag from their machine or teams may be attempting to plant their own flag on their opponent’s machine. One of the more prominent attack/defense CTFs is held every year at hacker conferences, such as DefCamp, where this activity is expected every year.
