Title: Hack.lu 2014
Date: 2014-10-25 1:27

I'm back from [hack.lu 2014]( http://2014.hack.lu )!

It was a really great 4 day long convention in Luxembourg, organised by the [CIRCL]( http://www.circl.lu )
(those guys are awesome) at the [Alvisse]( http://www.parc-hotel.lu ) hotel.

I did *two* 6h-long workshops about radare2 with [maijin]( http://maijin.fr )
and [xvilka]( http://xvilka.me ) in front of a crowed room: I think that in total, more than 60 people
attended! We didn't expected much people and planned only one workshop. But we ended up refusing
people and doing a second one the day after!

Maijin did the first part, dedicated to reversing and actually using radare2,
I did the second one about exploitation, and xvilka did the last (and most impressive in my opinion) one;
about reversing and analysing firmwares. It was exhausting, but really cool to show/speak about radare2
to interested people: Most of my speeches about it are aimed at newbies and only show basic usage.
It was surprising to get technical questions on specific points, usages and implementation details,
and quite impressive to see people actually using radare2 to craft working exploits after
a 10 minutes basic explanation of the involved commands.

Since I'm not using twitter I didn't had much feedback about the workshops,
but it seems that overall, people enjoyed it. The slides and practical materials
should appear on the [radare blog]( http://radare.today ) and on the [hack.lu archive]( http://archive.hack.lu/2014/ ).
You can also grab my slides on my [local mirror]({static}/files/hacklu2014_r2_exploitation.tar.xz ).

Sadly, I didn't had the time to play (with the [hackgyver]( https://hackgyver.org ) team)
the [awesome ctf]( http://2014.hack.lu/index.php/CaptureTheFlag ) organized by the [FluxFinger]( https://ctf.fluxfingers.net )
(Some of them attended the workshop!!!).
A couple of teams used radare2 for some challenges, watch for writeups!

I also did a 5 minutes [lighting talk]( http://2014.hack.lu/index.php/LightningTalks#Radare2_a_fast_overview )
 about radare2, in front of the whole assembly.
I originally planned to do it in 10 minutes, so it was quite an *interesting* exercice.
[udgover]( https://twitter.com/udgover) told me that *It was a nice lightning talk. Precise, concise and fun*,
so I guess it was ok-ish. Speaking in front of ~200 persons is a wonderful experience,
and I look forward to do a full-talk next time!

I'd like to highlight the fact that the food at hack.lu was _really_ great
(I spent almost all the con either eating or writing slides/doing the workshop).
Ho, and by the way, it seems that saying that you're looking
for an internship before doing your workshop is one of the best ways to get interesting offers ;)

I met a lot of _great_ people, friends, and made new ones, managed to actually see some talks,
greeted the Luxembourgian version of [nos oignons]( https://nos-oignons.org ): [Frënn vun der Ënn]( https://enn.lu ),
and even to put faces on some [io]( http://io.netgarage.org ) players/idlers.

I'd like to thank [pancake]( https://twitter.com/trufae) for radare2,
xvilka and maijin for bearing me, [crowell]( https://ctftime.org/team/285 )
for helping me to get a clean exploit for *Ropasaurus Rex*, my school for allowing me
to postpone my exams, and the hack.lu staff for inviting me!
