Hack.lu is an open cybersecurity conference held in Luxembourg where individuals may talk about computer security, privacy, information technology, and the cultural/technical implications of these topics on society.

Hack.lu (sometimes spelled HACKLU) is a yearly computer security conference hosted in Luxembourg that brings together a diverse group of people interested in data and information security. The Computer Incident Response Center Luxembourg (CIRCL), the country’s CERT for the business sector, communes, and non-governmental organizations, are both helping to organize the conference.

The inaugural conference was conducted in 2005, and the 10th edition was held in 2014. In the world of European information security conferences, hack.lu is one of the most established.

Whereas most conferences provide day-long training sessions, Hack.lu takes a different approach, covering the first few days with workshops and emphasizing the importance of practical skills. The convention’s goal is to provide a bridge between the many actors in the computer security industry by debating and presenting on issues such as computer security, privacy, information technology, and society’s cultural/technical implications.

A capture the flag event has been held every year since the inaugural conference. FluxFingers from Ruhr-University Bochum have organized the event for the fifth time in 2014. The event typically lasts 48 hours, with the option of participating remotely. However, only teams with one person physically present will be eligible for the award. In 2013, more than 400 persons took part.

Similar events in Europe could be the Chaos Computer Club in Germany, BSides events or TROOPERS.

We caught up with Alexandre Dulaunoy, founder of HACKLU to ask him a few questions about this security event in Luxembourg.

Hack.lu is (in my humble opinion) the best Cybersecurity Conference in Luxembourg and one of the best Hacker Conferences in Europe. Within the DACH and central European region there are hundreds of InfoSec events but some jump-out more than others and Hack.lu is one of those!

The feedback our community has given us about hack.lu is that this yearly computer security conference brings together a bunch of interesting personalities throughout Europe and beyond. Also, of interest, we note that the event has an association with the Computer Incident Response Centre Luxembourg, the country’s national CERT.

The first HACKLU (as it is often written was organized in 2005 so you can consider this as being one of Europe’s oldest hacker conferences.

Where other events are listed throughout our directory, this conference places focus on enforcing a strong ethic on the practical side of Cybersecurity. The HACKLU ethos it seems is to connect all stakeholders from within the security space and share ideas and research on subject matter like computer security and privacy.

The HACKLU CTF is legendary stuff too.

The FluxFingers team from Ruhr-University Bochum are the CTF event organizers and they oversee a CTF that lasts two days! Another event that springs to mind that offer another major CTF is NorthSec in Canada. You don’t have to physically be located at the event to participate, you can do so remotely which makes this CTF at a conference all that more fascinating.

What’s The “Best Thing” About HACKLU?
Small, open to everyone, inclusive, fun, and attractive. hack.lu started as a small event infosec event 15 years ago to bring the international security community in Luxembourg.

How Would You Like To See Your Event(s) Evolve?
Improving the library and archiving of the information and knowledge produced during the hack.lu conference. The 16th edition is focusing on producing a book with all the materials submitted and accepted.

What Do You Look For In Speakers And Their Presentations?
We have an open CFP [policy] where anyone can apply for hack.lu.

In Summary
Huge thank you to Alexandre for having taken the time to answer my questions and participate in our Conference Spotlight series.
