BalCCon CTF, hack but don’t get hacked!

The CTF is a hacking contests designed for security experts with the desire to compete against each other. CTF is a simulation of a real environment with exploitable devices and applications where security expert’s skills are put to the test. Besides real vulnerabilities in place there are some other task to solve, where creativity, focus, logic, ingenuity and other problem solving skills can glance. Once connected to the real environment hack but don’t get hacked!

Skills put to the test:

 * Networking services hacking
 * Network analysis and hacking
 * Web application analysis and hacking
 * Steganography
 * Hash cracking


CTF is taking place at BalCCon security conference. Competitors will connect to the hacking environment through Wi-Fi or wired connection which will be available only at BalCCon21k5 - The Museum of Contemporary Art Vojvodina. Before start they need to register at , where additional information about tasks and submission of solutions will be available.


Practical awards and of course Fame and Glory

Single-chip 2D Retro Game Console



Computer games of today are fascinating. But good old games, which we played 30 years ago, had a special kind of magic. They were limited by the rudimentary 2D animation, and as we know, limitations can be their own source of inspiration, especially versus the overwhelming surrounding of technology that we live in today. This Do-It-Yourself project enables you to build your own single-chip retro game console and take it home with you.


Last year you learned about Arduino, which was based on Atmel's architecture, and this time we prepared something new for you. You will build a stand-alone game console with Microchip's PIC microcontroller, and we will show you how to solder, help you assemble the console and guarrantee that everybody will end up with a fully functional game console. All visitor can buy the kit, which contains all the electronic components and mechanical parts, and build it in our workshop.

Game Description:

The classic game Jumping Jack is well known to all the computer enthusiasts which were playing around with the Spectrum computer in the 1980's. The hardware, which you will assemble here, is ready to play the game, without loading or booting up - all you have to do is to connect the console to any standard VGA monitor, and to connect the 5V power supply, or to your computer, via mini USB cable. If you want to have music and game sounds, you can also connect any standard PC speakers or headphones. The full game description is at


Hardware Description:

The kit contains all the components and mechanical parts, Including a high quality double-layer Printed Circuit Board, ready for soldering. All the components are "solder-thru" type (none of them are SMD), so the soldering will be easy even for beginners. The keys are mechanical, very robust and durable.
This console is stand-alone, so it needs no computer to work. If you supply it from your PC via USB cable, it takes only 5V for power supply, as this game does not use USB port signals.

You can see the schematic diagram and components placement at

  • Dimensions: 110×50×20 mm.
  • Weight: 90 g.
  • Microcontroller used: PIC24EP512GP202 (16-bit MCU, 512K Program Memory, 48K Data Memory, 140 MHz, 70 MIPS)
  • VGA output: 800×600 mode, 760×480 used as 380×240 pixels
  • Power consumption: 77 mA @5V

Workshop Itinerary:

Participants will be instructed by Voja Antonic, and each of the following steps will be covered by conversation about schematics diagram, components functions and characteristics and soldering technique: A short lesson about electronic components used in this project A lesson about soldering, with some experimenting for beginners Assembling the units Testing the units and playing the game

More info about lecture and workshop:

Modern information and communication technology has penetrated our lives today. Smartphones, tablets, computers and the Internet have become so self-evident that we rarely think about how these technologies of global networking have changed the way we work and communicate - or the risks that come with it.

The rapid global access to data and information that simplifies and enriches our work and our lives, is also our greatest vulnerability - it is now quite possible to intercept our communications on the network, to identify our user profiles, to access our computers and to tap off our data - all without us noticing.

In addition to doctors and lawyers, journalists are encouraged to assume a special duty of care for their information and data regarding sources and clients. With the use of computers and the Internet, this duty of care can not be passively exercised; the legally guaranteed protection of sources and clients no longer suffice. Journalists must actively seek protection of their communication and their data - and this usually requires external know-how to assess a situation-specific hazard correctly and to find the appropriate measures to avoid damage.

To facilitate this task, we offer a workshop specifically for the journalistic environment. In these events, the handling of the available technical protection measures are taught in addition to the necessary understanding of the dangers in the use of computers and the Internet.

Basic Lecture "Situation Awareness for journalists"

This one-day workshop teaches the basic knowledge to develop a new situation awareness for dealing with computers and communications technology in journalism. The number of participants in a seminar is not limited; the implementation is usually carried out in two parts.

It gives answers to the following questions:

  • How are confidentiality, integrity and anonymity (from sources) threatened by the use of computer and communication technology?
  • What are the basic safeguards for the use of computers in the journalistic environment?
  • What should I know about passwords and their use?
  • How do I secure my communications on the Internet (Web Browser, Email, IM) and on the phone?
  • What is encryption and how do I use it?
  • How do I save information safe from unauthorized access?
  • How I recognize and avoid metadata in documents and images?
  • What should I specifically note in foreign missions?
  • How do I deal with printed information correctly?
  • What should I know about Social Networks?

Workshop on "handling of technical protection measures"

There are various workshops offered, which can be visited either individually or in combination depending on the task and operation of the editorial staff. The participants learn at their own computers and in their usual working environment how the use of technological protection measures can minimize the risks and dangers as described in the seminar.

The number of participants, should be approx 8-12 people

  • E-mail encryption
  • Using TAILS as a safe working environment
  • Using Tor and VPN for secure Internet use
  • Encryption of files and disks for secure data storage

August 08th 2015


On BalCCon2k15 we want to put also focus on groups meeting and discussing topics. For many groups it was hard to find a decent home base to discuss ideas and get new folks interested in their community. For interested hackers it became harder to find someone to talk to, as everyone was wandering around.

We have a solution for that: "Hackerspace" on BalCCon. We want to capture the camp's spirit in semi-open assemblies called "Hackerspace" ;)

So, if you are a group of hackers who like to work and hang out together, bring your toys, work on projects, have fun and let others participate in what you’re doing!

How to reserve space

Please let us know what you’d like to do, how much space you’ll need, what you’d like to bring with you, how much power your gear will consume, etc… Keep in mind: The more you tell us about your plans the better your chances that you’ll actually get what you want.

  • send an email on jelena (at) with subject BalCCon2k15 Assembly

Be aware: Only Assemblies that were added until 06st September will get an own place!

So we bring our projects and set up workshops and so on?

Yes, sharing your knowledge and showing other participants about your projects is central for everything going on at the congress. If people in your Assembly want to offer workshops or maybe lectures on a small scale, maybe there’ll be enough space for you to integrate a workshop area into your Assembly. For bigger workshops there will be workshop room.

Great, we will bring ALL THE THINGS!

Be aware that the space is limited. But assemblies are invited to bring their toys and also to decorate their spot on the Congress – as long as everything you bring with you does not block exit paths and is not inflammable. These two requirements are important, and if your installations don’t fulfil them, we’ll be forced to remove them.

Yes, we will do some workshops!

If you would like to have small-scale workshops in your Assembly, tell us what you’re planning and for how many people. Please be as specific as possible. We will probably not allocate extra workshop space for your Assembly, if you haven’t published something like a schedule on your Assembly page. For now it will be sufficient to list topics and speakers, later we’d like to see a timetable as well.

How about a projector for our area?

We will not provide projectors, canvas or anything apart from chairs and tables, but probably you’ve got those anyway.

List of already registered assemblies

Coming soon!
