CTF foo
Capture The Flag foo
Art	Meet-Up
Datum	every other saturday
Start	14:00
Host	hanemile
Relevant?	Yes

An event focused on "Capture the Flag" Events. The main point here is to get people into the security field in a welcoming way and provide a space for interested people to exchange knowledge.

The individual events which take place every two weeks have a dedicated topic, but we're also quite flexible and can look into other stuff (So if you've got a topic you might be interested in, bring it up!).

We'll look at specific topics at each event and maybe play some CTF that is currently running afterwards in order to try out our newly learnt skills.

Here's a list of the past events giving you a brief idea on what we're doing:
