Just a few days ago I had the pleasure of visiting Day-Con X. I listened to some great talks in the closed and public sessions. Since the first day was the security summit (closed session) I will just name a few titles with some brief words.Continue reading
As you might have read, I recently had a closer look at how easy it actually is to become part of an IoT Botnet. To start a further discussion and share some of my findings I gave a quick overview at the recent Dayton Security Summit. The Mirai Botnet was supposed to be one of the case studies here. But the way things go if one starts diving into code…I eventually gave an overview of how the Mirai Bot actually works and what it does. As such: Here a quick summary of the Mirai Botnet bot.

Welcome to Dayton
In mid-October our friend Bryan Fite aka Angus Blitter invited the community for the ninth edition of Day-Con. Bryan’s annual security summit, which we regard as the sister event of TROOPERS, is a pretty good reason to visit lovely Dayton, Ohio.
And so we did… ERNW sent in five delegates. Delegates is Day-Con-speak for all attendees and speakers and such a subtle choice of wording sets the tone for the whole event. People seemed to be really focused and the roundtable-like setting during the talks (see above) provided a cozy atmosphere for in-depth expert chatting.Continue reading
Some of us had the pleasure to participate in this year’s Daycon VII, three days of Real Hacking and Relevant Content, in Dayton, OH. The event began on September 16th with the Packetwars bootcamp. We had the chance to teach some really promising young students and to prepare them for the Packetwars battle that was scheduled four days later. The students had to go through topics like Windows security, network security and web application security both practical and in theory.Continue reading
Two weeks ago we had a great time at Day-Con VI. Enno, Matthias, Rene, Frank and me traveled to Dayton, OH to give workshops and presentations. We started a tough week full of workshops on Tuesday where Rene gave a deep inside look into the world of security on current mobile platforms. Matthias discussed security problems and possible design patterns of cloud environments in his Cloud & Virtualization Security Workshop before he gave a first insight into the world of reverse engineering on Wednesday. Frank and me taught the basics of hacking and pentesting in the PacketWars bootcamp (comparable to the one at TROOPERS), preparing the participants for the PacketWars on Saturday. Obviously we were not the only ones having a great time 😉
During the main conference day on Friday several talks about trust, gaining trust and measuring trustworthiness took place. As one could write books about the whole trust issue, Dr. Piotr Cofta did exactly this and hence was a perfect choice for the inspiring keynote on basic approaches to measure trust. As we also gave several talks throughout the day, you can find our material both on the Day-Con website and in our newsfeed.
We enjoyed our time in Dayton & see you there next year,
As every year, we will be attending Day-Con, a one-day security summit in Dayton, OH — this year for its VIth edition. Even though the actual conference comprises “only” one day full with talks and discussions (please find the agenda here), the overall event consists of trainings before the conference and PacketWars battles (including an infamous party) afterwards. Since we will be leading and attending some of the training sessions, those might be of particular interest for people who missed our Troopers workshops — so you don’t have to wait a whole year but get another chance in October 😉
- October 12th: Conference (Agenda)
- October 13th: PacketWars (including the infamous party)
See you there & have a good one,
During the last days, some of our guys (including me) had some great days in Dayton. Rene, Christopher, Hendrik, Sergej, and me flew in to give workshops and presentations at Day-Con as well as to compete in the infamous PacketWars game. While Day-Con is a one day event, the two days before the conference comprised workshops on secure iOS integration (given by Rene) and IPv6 security (given by Christopher). Since the overall topic of the conference was trust, Rene gave a keynote on broken trust which was based exemplary trust analysis, development of a trust metric, and different trust factors. Those trust factors were also used in my talk about evaluation methodologies for cloud service providers (regular followers will recognize some of the content of both talks from different posts 😉 ). There were also talks from Sergey Bratus, Graeme Neilson and Angus Blitter. While Sergey proposed a sound (not to say academic 😉 ) definition on the classification of vulnerabilities and their connection to turing complete input languages, Angus gave an introduction to PowerLine technologies and laid out, that these technologies still suffer from naive assumptions about trusted networks (he also refered to this). The day after the conference, the ERNW Allstars had to defend their championship title in PacketWars. Since the first battle was scheduled for 10AM, we had quite some time to tan in the sunny 30°C weather, recover from the conference and prepare the expected victory celebration (some of you might remember some “Champagne tradition” from Troopers). In face of this motivation, we rushed through the 3 battles and were able to score first place second year in a row. At this point, kudos to the two other participating teams who gave us a tough battle, especially during the reversing challenges.
Have a great week, MatthiasContinue reading
… which was, as in the years before, an awesome event. Great talks, great people, great fun.
Bruce Potter gave a keynote which did exactly what a good keynote should do: make the audience think and entertain it at the same time.
[Those readers familiar with ERNW’s security model will certainly notice that we do not necessarily agree with everything he said. We still think that – in particular in times where infosec resources are scarce anyway – putting your bets on prevention provides a better cost/[security] benefit ratio than going for extensive detection capabilities.
Fix the doors first, then think about installing a CCTV.
Still, human nature tends to exchange “good security with low visibility” for “poor security with potentially good visibility” quite easily… as can be noted every day in many environments.]
Sergey provided an excellent & insightful piece on security in times of very large numbers of embedded devices (like smart meters).
And, last but not least: football is coming home. The “ERNW Troopers” team consisting of Rene Graf and Michael “Bob the Builder” Schaefer managed to win the event’s PacketWars contest. Congrats! Great job, guys.
have a great weekend everybody,
For the record: Graeme’s and my presentation on Supply Chain Security can be found here.Continue reading
