Some outright rants from a bunch of infosec practitioners.

Troopers is (unfortunately) over. It was a blast (but I may be biased ;-))! After things have settled, I want to take the opportunity to reflect my thoughts and impressions on the IPv6-only WiFi we had deployed during the conference. To make sure that everybody is on the same page let’s start at the beginning.

In the last couple of years we had provided Dual-Stack connectivity on the main “Troopers” SSID but also had an additional IPv6-only SSID. This year we decided to spice things up and made the “Troopers“ SSID IPv6-only (with NAT64) while providing Dual-Stack connectivity on the “Legacy“ SSID. We wanted to get a feeling how many clients and applications can work properly in an IPv6-only environment. We intentionally didn’t announce it vastly beforehand, hoping that attendees would just connect to the main SSID without noticing anything. We were aware that some applications might expose issues but, as I said , we wanted to get a feeling to which degree problems actually occured. (more…)

I’m back from London where I gave a talk about security evaluation of proprietary network protocols. I had a great time at InfoSecurity Intelligent Defence and BSides London, many thanks for inviting me and giving me the opportunity to speak to so much nice people.

Find the abstract and the download link to the slides after the break.

HackInTheBox and Haxpo – 2014

Haxpo Overview 2014

Haxpo Overview 2014

Past month we (which is me and a group of other ERNW students, supported by some of the “old” guys — I hope my team lead won’t yell at me for this 😉 ) attended the Haxpo and Hack in the Box in Amsterdam. Starting from 28. May, we had three days at this great conference (HITB) and exposition (Haxpo). The two events took place in the former building of the stock exchange in Amsterdam, called: “Beurs van Berlage”. Upon entering the building for the first time we were given details on where our booth was and where the talks would take place — setting up our booth and planning the shifts was just another thing to do before exploring the Haxpo area:

A quick update on the workshop we’ve just finished at Hack in the Box 2012 Amsterdam:
Due to popular demand we decided to bring the slides online without wasting any more time. The official website of the conference is currently experiencing some problems due to high interest in all the stuff what was released in the last two days. Great conference!

Enjoy and feel free to express your thoughts in the comments.

Best greetings from Amsterdam,
Florian & the crew

TROOPERS11 – Slides available

TROOPERS11 slides are available now! Please find them here:

TROOPERS11 was a blast! We received great feedback from all attendees and speakers. This really pushes ourselves towards the next goals and an even better security conference in 2012.

We’re happy that everybody got home safely with new ideas and inspirations in mind. On a side note: The awesome TROOPERS badge caused trouble for some of you with the airport security 😉 I really hope everybody could find a way to take it back home. It will hopefully find its way to an adequate place right next to your old memorabilia (cup of the first won soccer match, your college degree or photos from your first ballet show). Regard it as the proof of your latest achievement and tell everybody proud and loud: WE ARE TROOPERS.

Best regards,

PS: Videos and photos are coming soon. Stay tuned.

Try Loki!

Loki is set free!

Everybody who is interested in our newest tool ‘Loki’ is welcomed to head over to ERNW’s tool section and download it. Take this monster for a spin and let us know in the comments how you like it. Loki’s coding father Daniel is more than happy to answer your questions and criticism.

You don’t even know what Loki is?

In short: An advanced security testing tool for layer 3 protocols.

In long: Have a read in the Blackhat2010 presentation slides and mark TROOPERS11 in your calendar to meet the guys behind the research and for sure get a live demo of the capabilities – development is still ongoing, so prepare yourself for even more supported protocols and attack types.

And again: Talking about TROOPERS11… we’ve already selected the first round of speakers. Details to be published soon 🙂

Have a great day!
