DeepSec Conference Videos

René Pfeiffer/ May 27, 2011/ Administrivia, Conference

Finally we found some time to sort through the video recording legacy of past DeepSec conferences. We’ve been asked for video material repeatedly since we record all talks held at DeepSec (except those where the speaker does not want to be published on video). Let me explain what the state of our video archive is. All video recordings were done by different teams consisting of video professionals, volunteers from Metalab and students of the St. Pölten University of Applied Sciences. We used different camera equipment, sound feeds due to changes with the audio system on-site and various storage media because of different digital cameras on-site. The videos of DeepSec 2007 are on Google Video since June 2008. We have re-added them to our internal archive, and we noticed that killab66661 has added the videos

DeepSec 2011 Focus: Security Management and IT Governance

René Pfeiffer/ May 23, 2011/ Administrivia, Conference

Have you lost track of the risks that may or may not impact your security? How good are the facts you base your security decisions on? Does your organisation follow defined procedures in terms of deploying, monitoring or evaluating security measures? Who decides what’s next and what’s being phased out? Is there a way to get more sleep while fencing off risk factors at the same time? It’s very easy to get lost in the details and drown in the various tools of the security trade. Every day something happens. A single 0day can ruin your meticulously designed schedule. It would be nice to get a grip on the dynamics and introduce more stability. CIOs need to address the Big Picture. That’s exactly why we mentioned security management in our CfP. We’d like to

Thoughts about Threats by „Virtual Bombs“

René Pfeiffer/ May 22, 2011/ Security

The German Federal Minister of the Interior, Hans-Peter Friedrich, has warned „that it is only a question of time until criminal gangs and terrorists have virtual bombs at their disposal“. While the term „virtual bomb“ is very vague by itself, the minister mentioned „malware“ as well. This is no surprise for security researchers. Malicious software has already been used for attacking companies. The infrastructure of whole countries has been attacked as well. Logic bombs have been used in the past, but they have never been used to wage warfare. They have been used for revenge by disgruntled employees or for blackmailing someone (as the ransomware malware also does). Tools like this are used for very specific purposes (such as espionage or targeted destruction), but never for an all-out assault. Even a (D)DoS often has

Mobile Network Security revisited at the Linuxwochen

René Pfeiffer/ May 20, 2011/ Veranstaltung

Tomorrow we will present a review talk about the state of mobile network security. The talk will be held at the Linuxwochen in Eisenstadt. We will address results discussed in the past DeepSec conferences (including work of Karsten Nohl, Harald Welte, David A. Burgess, Sylvain Munaut, Dieter Spaar, Ralph-Philipp Weinmann and others). If you understand German we recommend listening to Chaosradio Express #179 where Karsten explain to Tim Pritlove the state of GSM security over a period of 130 minutes. Slides of our talk will be available after the Linuxwochen. Update: You can download the slides here. There’s a simple audio recording available as well (MP3 or OGG).

Mobile Security and authTokens

René Pfeiffer/ May 17, 2011/ Security

Recently we mentioned the topic of mobile security in this blog since it keeps being addressed by security researchers. Now there’s something that can be combined by networking, defective by design and mobile security. German security researcher from the University of Ulm have explored a flaw in Google’s ClientLogin protocol. The initial idea stems from Dan Wallach, who took a closer look at the transmissions of an Android smartphone. The authentication token is sent via unencrypted HTTP which means it can be seen by attackers on the same network. Since the token is your key to online services and is probably used by apps dealing with your calendar, contacts or private pictures, an attacker has full access to this data (or any other data an app deals with via the network).

DeepSec 2011 Focus: IPv6 and Next Generation Networks

René Pfeiffer/ May 13, 2011/ Administrivia, Conference

Since 3 February 2011 the IPv4 pool is now officially and fully depleted. „Peak IPv4“ was a long time ago. IANA can no longer hand out any IPv4 address space. Everyone who needs more address space will be force to look to IPv6. What about security? Are there any benefits? Has IPv6 eliminated all the weaknesses known with IPv4? Those who attended DeepSec 2010 already know the answers to these questions. Mark Heuse conducted a workshop and held a talk about IPv6 security. There’s no doubt that IPv6 is coming to town. Due to tunnels some networks even have IPv6 connectivity, some without even knowing. Setting up a tunnel with a router in your local network is easy. The router will announce itself to local nodes which will in turn automatically grab addresses and

Talks held at the Linuxwochen Wien

René Pfeiffer/ May 8, 2011/ Security, Veranstaltung

MiKa and me held three talks at the Linuxwochen Wien 2011. The scheduled talks were „VoIP Security“ and „The Wind Chill Factor of Security“. The third talk was a review of the trust models used with X.509 certificates and issued by certificate authorities. The review was a drop-in replacement talk for a speaker who did not show up. Since the talks were held in German, I’d like to present a short summary in our blog. VoIP has become a well-established technology in companies during the past years. Periodically we assess the security of VoIP protocols and implementations. The talk we gave was a review of the state-of-the-art focussing on SIP signalling and audio/video codecs. We discussed the basics, the SIP Digest Authentication Leak found by Sandro Gauci, SIP probes, the troubles of SIP gateway

Article about White and Black Hats in Wiener Zeitung

René Pfeiffer/ May 6, 2011/ Press

Christoph Rella, a journalist who has been at past DeepSec conferences made telephone interviews with MiKa and me. He explored the difference between White Hats and Black Hats along with the motivations of hackers. He was interested in getting to know the reasons why the stereotype of the nice IT guy turns criminal. We think the motivations are vastly different, money being among them. Mr. Rella published a summary in an article for the Wiener Zeitung (in German).

Zu Gast bei Taalk.at: Vorratsdatenspeicherung

René Pfeiffer/ May 3, 2011/ Discussion

Michael Kafka war am 29. April 2011 zu Gast bei einer Expertenrunde zum Thema Vorratsdatenspeicherung. Der Hintergrund ist die Speicherung von Verbindungs- und Geodaten bei Kommunikation über Internet, Telefon und andere Netzwerke. Die EU Richtlinie dazu muß in allen Mitgliedsstaaten umgesetzt werden. In Österreich wurde das Gesetz letzte Woche beschlossen und tritt am 1. Januar 2012 in Kraft. Da Netzwerke und Logdaten mit dem Thema Sicherheit verwoben sind, haben wir unsere Expertise in die Diskussion eingebracht. Im Web-Standard wurde ein Artikel publiziert. Die Videoaufzeichung läßt sich über die ichmachpolitik.at Webseite anschauen:

DeepSec 2011 Focus: Mobile Computing and Communications

René Pfeiffer/ May 2, 2011/ Conference

Our Call for Papers announcement mentioned seven topics that we are focussing on. We’d like to explain what these topics are all about in a couple of blog postings since it is not easy to squeeze everything into a few lines. We begin with mobile computing and communication. Mobile computing incorporates mobile computing devices such as smart phones, tablets, cell phones, laptops, netbooks, wrist watches, navigation devices and similar computers. Most of us are now accustomed to frequently use portable computing. We want to know what bugs and security risks we carry around. A lot of users regard these mobile computers as appliance, therefore the thought of upgrading or fixing software on them is less widespread. You don’t do firmware upgrades on your microwave oven or water boiler, do you? Maybe you should. Mobile

Data Leaks Reviewed

René Pfeiffer/ April 28, 2011/ Internet, Security

Often single incidents don’t attract much attention, but the combination does. We’re getting used to lost laptops, USB sticks, CDs/DVDs/HDs and gadgets containing data. There’s even a project trying to keep track of data loss incidents world-wide, it’s called DataLossDB. Compromised web sites are also quite common. Only figures raise eyebrows, so this week’s favourite news item is Sony and the PS3 network. Someone created unauthorised backups of database tables containing (encrypted) credit card information, user names, passwords, birth dates and home addresses of PlayStation Network users. We still don’t know the nature of the security breach, however the impact is substantial both in terms of number of stolen records and very probably financial damage. There’s been not much talk about the passwords and their data format, but we all know that few people

Hacking Transportation Devices – 0wning Cars!

René Pfeiffer/ March 17, 2011/ Security, Stories

Last Summer we published a short article about an experimental study of modern car sensors systems and their security. Researches took a modern car, connected to the internal data bus and tried to do some hacking. They were able to manipulate on-board systems up to controlling the brakes and the engines. The study shows that once you have access to the (internal) network, you can do things that were most probably never anticipated by the designers. Arguably the risks of these kind of attacks is rather low – for now. However if you think about the Internet, software working in networked environments or the plethora of devices that can be connected to computers, then the number of attack vectors increases. This is not breaking news. You can see this trend in the wonderful world
