SDR and non-SDR tools for reverse engineering wireless systems

Hey there!
The God of frequencies Michael Ossmann visited us again this year at the TROOPERS16 and showed us how to break another device using a specific setup.

Last time he introduced the HackRF One to us (Read here:https://www.insinuator.net/2014/08/hackrf-one-the-story-continues/), but this post is a short summary of his talk about “Rapid Radio Reversing”, he is a wireless security researcher, who makes hardware for hackers. Best known for the HackRF, Ubertooth, and Daisho projects, he founded Great Scott Gadgets in an effort to put exciting, new tools into the hands of innovative people.

Reflections on the IPv6-only WiFi Experience during Troopers

Hello,

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.

Troopers 16 – Taking the Badge to yet Another Level!

Real men used to wear pink pagers, but that’s the past and recently it was time for Troopers 16. Meaning: Real Troopers wear awesome Badges! And, from the feedback we got, they did!
Troopers might be over, but the era of the TR16 Badge is seemingly just beginning. As such, here’s a quick insight into the badge!

Troopers16 – GSM Network

Hello Troopers!

only a few seconds left! As a short reminder, there is a GSM network running on Troopers 2016. It should be available in the whole building. To attend the network you need to

  • Get a SIM Card @Troopers_Desk
  • Put it in your phone
  • Start the phone

That’s it!

You can always dial *#100# to get your phone number. All further information (and a phonebook) you’ll find on gsm.troopers.de, but here again a brief summary:

  • gsm.troopers.de
  • Phonebook
  • Update your name in phonebook via sending your_name to 1000
  • Submit tokens via sending your_token to 1111 (you must register at the terminal first)

Please note, against to our announcement, there is not Internet (GPRS) yet. Due to questions and problems, please contact Kevin Redon or Hendrik Schmidt. Have fun!

Multicast Based IPv6 Neighbor Spoofing / Response Behavior on Cisco Devices

Dear readers,

today we want to examine the behavior of Cisco devices when they receive spoofed IPv6 Neighbor Advertisement packets from an untrusted system pretending to be the default router for the local segment. We start with a quick refresher how Cisco devices behave in the legacy (IPv4) world when they receive a spoofed broadcast ARP packet containing the IP address of the device but with a different MAC address, followed by a discussion of the corresponding behavior in the IPv6 world.

Observations from the Cisco Live Europe 2016 Wifi Infrastructure

Good Evening,

Enno and I spent the first day on Cisco Live Europe in Berlin today attending the “Advanced Practical Knowledge for Enterprise Deploying IPv6” technical breakout held by Tim Martin and Jim Bailey. It was a good breakout session, and thanks again Tim for the honorable mention of our work in your slides! We really appreciate it. Like last year, we were curious how the Wifi network was setup this year as I face a corresponding task for Troopers in March, with some major changes in comparison to the last years.

#TR16 IPv6 Security Summit Teaser: Basic IPv6 Attacks & Defenses Workshop

Dear Readers,

It’s me again with another teaser for an upcoming workshop at the IPv6 Security Summit. This one is a classic! If you happen to deploy IPv6 in your environment in the near future, but didn’t had the time to think about the security implications, this workshop is the right place to start.

Multiple Address Family OSPFv3

Dear Readers,

today I want to talk about OSPFv3. I won’t cover the glory details of OSPFv3, there are smarter guys than me out there who did that already 😉 and there are great resources to familiarize yourself with the protocol. However, it should be noted that OSPFv3 is not only OSPF for IPv6, OSPFv3 brought some major enhancements compared to OSPFv2. Wouldn’t it be cool to benefit from the enhancements in the IPv4 world as well? Continue reading “Multiple Address Family OSPFv3”
