kr3ts: Intro to C and Assembly

assembly language

The kr3ts hackerspace invites you to a beginners guide to programming in C and Assembly language.

Tuesday the 10th, 18:00 at Nattsvart

It will be a great warmup for anyone interested in the upcoming Kernel Module Workshop (24th March).

Learning low level programming languages like C and Assembly is useful for anyone that want to learn more about how a computer actually works. It’s also a great skill to have when writing exploits, reverse engineering code and optimizing computations.

Gotta Pick ’Em All!

Lockpicking is fun! Do you want to learn how to do it? The kr3ts hackerspace throws a lockpicking party at Nattsvart on the 26th Jan and you are invited. We will start at 12:00.

We will be practicing our picking skills and anyone that wants can join, regardless if you have done this before or not. This is happening in parallel with Piratkökets “brunch buffet”. Come for the food, stay for the picking.

We provide lock picks and instructions. We also have some locks to try out. If you have a lock of your own, bring it and try to pick it. Any type of lock is fair game: combination locks, bike locks, locks with keys of any shape or form.

We are planning a separate event for picking electronic locks and contactless “blipp” keys later this year. Stay tuned for that.

Let’s Play a Game!

The Nattsvart hackerspace kr3ts invites you to join us for the Insomnihacks Online CTF on the 18th Jan.

WTF is a CTF you ask? Well, a Capture the Flag (CTF) event is a kind of hacker competition. In this case a conference is hosting the competition. They have prepared a number of vulnerable websites, mysterious programs to reverse engineer and cryptos to break. On Saturday the 18th Jan we will be hanging out in Nattsvart and participating in this competition as a team.


If you have never played a CTF, but think you might like it, we would love to have you on our team. Playing a CTF requires some basic programming skills, but more specific hacking skills is not a prerequisite. Send an email to if you would like to join us for this event.

We are also hosting a CTF warmup on Tuesday the 14th starting at 18:00. This is a great time to drop by if you have any questions or want to meet the kr3ts CTF team. We will be playing around with some tools that could be useful during the competition.
