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:

Troopers16 – GSM Network

Same as last year, we will have a GSM based telephony network running at Troopers 2016. The network will be a closed network, which means it only can be used with Troopers SIM cards and between Troopers attendees only. You can use the network for

  • doing Voice Calls
  • send Short Messages (SMS)
  • have Internet Access
  • submit Challenge Tokens (see below)

In contrast to last year, you will need a Troopers SIM card to attend the network with your cellphone. The SIM cards will be handed out at the registration desk; if you have questions you always can contact me or Kevin Redon (thanks again for assisting us).

TelcoSecDay 2016 – Second Round of Talks

I am very happy to announce the second round of talks for the TelcoSecDay 2016. As mentioned in my previous post it will take place on March 15th. All invitations should be out by now; if you think you can contribute to the group and you are willing to join us – please let me know (hschmidt@ernw.de).

Still, not all talks are confirmed but the newly published talks will provide an idea about TSD 2016 and its discussions.

TelcoSecDay – First Round of Talks

Dear all,
This year the TelcoSecDay will take place on March 15th. For those of you who does not know about: the TelcoSecDay it is a sub-event of Troopers bringing together researchers, vendors and practitioners from the telecommunication / mobile security field.

The event is celebrating its 5th anniversary now, that’s why I’d like to say “thank you” to everybody taking part at this very great discussion round in the last few years. We always had a lot of very good feedback and interesting discussions and the increasing participation list of operators from year to year says (almost) everything!

Security Analysis of VoLTE, Part 1

Hello everybody,
this time I’d like to share some thoughts and results about our telco research last year. We gathered a lot of information out of some projects we’d like to share and discuss with you. The following sections also provide an idea of the upcoming Telecommunication Security Workshop I will give with Kevin Redon at Troopers (click). The workshop will be about Radio Network Security (covered by Kevin) and security aspects of the Core Network (covered by myself), mainly focusing on Voice over LTE (VoLTE). That’s also the topic of today’s post.

How to Get a BaseStation

In our talks in the past we showed what might be possible if an attacker gets access to backhaul and/or core network of a telecommunication provider. In a security analysts perspective this is really disgusting, but provider always will argument that those attack scenarios are not realistic.

 Because of legal restrictions we are not able to demonstrate this in practice (e.g. by breaking in into a BTS environment somewhere in the woods) but what we can do is this: building a lab.
Sometimes it is really shocking what you can buy on Ebay, right? Here we got one very interesting component: a Huawei BBU3900 BaseStation which is used by a couple of providers. Okay, it is for GSM-Rail, but the technology behind is very equal. And for 100 dollars (plus shipping) you don’t ask further questions…

GSM@Troopers

Additionally to Wifi, Troopers is also offering a GSM network.
If you want to use it, simply ask your phone to scan for available mobile networks. There you should see the usual T-Mobile D, Vodafone.de, E-Plus, O2-de operators, but also the unusual D 23 or 262 23. Just select this one, and your are done. You also can use the Troopers SIMs which you get on the welcome desk on the ground floor.

Telco Research 2015

Hello and a happy new year 2015 to everybody!

As follow up of our 2014 talk “LTE vs. Darwin” I want to inform you about our telco research in 2015. We are currently dealing with the so called IP Multimedia Subsystem (IMS), which handles the call and media logic of 4G telecommunication networks. This network part provides functions like VoIP (or VoLTE) and takes care of the interconnection to other call or media related networks.

Hackito Ergo Sum 2014

Greetings from Heidelberg to Paris,

and thanks for a great time at HES14! A nice venue (a museum), sweet talks and stacks of spirit carried us through the three day con. It all set off with a keynote byTROOPERs veteran Edmond ‘bigezy’ Rogers, who stuck to a quite simple principle: “People do stupid things” and I guess every single one of you has quite a few examples for that on offer. Next to every speaker referenced that statement at some point during her/his talk. Furthermore we presented an updated version of our talk LTE vs. Darwin, covering our research of security in LTE networks and potential upcoming problems.
