DeepSec2016 Talk: Smart Sheriff, Dumb Idea: The Wild West of Government Assisted Parenting – Abraham Aranguren & Fabian Fäßler

Sanna/ November 4, 2016/ Conference, Legal, Security, Stories

Would you want to let your kids discover the darker corners of the Internet without protection? Wouldn’t it be handy to know what they do online, to be alerted when they search for dangerous keywords and to be able to control what websites they can visit and even when they play games? Worry no longer, the South Korean government got you covered. Simply install the “Smart Sheriff” app on your and your kids’ phones. Smart Sheriff is the first parental-control mobile app that has been made a legally required, obligatory install in an entire country! Yay, monitoring! Well, something shady yet mandatory like this cannot come about without an external pentest. And even better, one that wasn’t solicited by the maintainer but initiated by the OTF and CitizenLab and executed by the Cure53 team!

BSidesLND2016 Rookie Track Review

René Pfeiffer/ June 11, 2016/ Discussion, Security, Stories

Sitting through the Rookie Track at BSidesLondon is something we really enjoy. This year the quality of the presentations was amazing. Of course, the rookie’s mentors take a part of the blame for that. Good training gives you always a head start. Nevertheless someone has to stand in front of the crowd and fill the 15 minutes slot with content. All rookies did a good job. It was hard to pick a clear winner. The jury took more than three iterations to find a conclusion. Locard made it, and we welcome him to DeepSec 2016 in November. Honourable mentions go to @Shlibness, @Oxana_Sereda and @callygarr. For you we have some thoughts on the presentations we saw and on the methods being used. Think of your presentation as code. Make it lean and mean. It’s

DeepSec Video: Visualizing Wi-Fi Packets the Hacker’s Way

René Pfeiffer/ March 3, 2016/ Communication, Conference, Security, Stories

Like the Force wireless data/infrastructure packets are all around us. Both have a light and a dark side. It all depends on your intentions. Lacking the midi-chlorians we have to rely on other sources to get a picture of the wireless forces in and around the (network) perimeter. At DeepSec 2015 Milan Gabor held a presentation about visualisation of wi-fi packets: Today visualizing Wi-Fi traffic is more or less limited to console windows and analyze different logs from an aircrack-ng toolset. There are some commercial tools, but if we want to stay in the Open/Free Source Code (FOSS) area we need to find better solutions. So we used ELK stack to gather, hold, index and visualize data and a modified version of an airodump tool for input. With this you can create amazing dashboards,

DeepSec Video: DDoS – Barbarians at the Gate(way)

René Pfeiffer/ February 23, 2016/ Conference, Internet, Stories

Unfortunately the Internet doesn’t follow the rules of economic theory. Unlimited growth is a myth best kept for feeding your unicorns. Of course, the Internet has grown, but the mathematics and physics behind network flows stay the same. If your pipe is full, then you are going nowhere. This is why Distributed Denial of Service (DDoS) attacks still work. You can counter or evade these attacks, but they can happen. We invited Dave Lewis of Akamai to DeepSec 2015 to hear his view on the current state of affairs where DDoS is concerned. For the record: DDoS is not hacking and no hacking attack. Spread your „cyber“ somewhere else.

DeepSec Video: ZigBee Smart Homes – A Hacker’s Open House

René Pfeiffer/ February 19, 2016/ Conference, Security, Stories

The data protocols of SmartHomes are the FBI’s wet dream. Why? Because they have no security design. Take ZigBee for example. ZigBee is one of the most widespread communication standards used in the Internet of Things and especially in the area of smart homes. If you have for example a smart light bulb at home, the chance is very high that you are actually using ZigBee by yourself. Popular lighting applications such as Philips Hue or Osram Lightify and also popular smart home systems such as SmartThings or Googles OnHub are based on ZigBee. ZigBee provides also security services for key establishment, key transport, frame protection and device management that are based on established cryptographic algorithms. So a ZigBee home automation network with applied security is secure and the smart home communication is protected?

DeepSec Video: Extending a Legacy Platform Providing a Minimalistic, Secure Single-Sign-On-Library

René Pfeiffer/ February 17, 2016/ Conference, Stories

Even if you are not running a mainframe you probably have some old applications which you still need and whose code you cannot lift into the present (technology-wise). This is something you need to address. Despite decades of security research and authentication standards there’s still a vast amount of systems with custom solutions and embedded user databases. Such systems are typically hard to securely integrate with others. We analysed an existing system of an organisation with approximately 12.000 sensitive user data sets and uncovered severe vulnerabilities in their approach. We developed a minimal, secure Single-Sign-On-Solution and demonstrated the feasibility of implementing both a minimal Identity Provider and a minimal Service Provider with only a few lines of code. We provided a simple blueprint for an Identity Provider and an easy to use Service Provider

Encryption – A brand new „Feature“ for Cars

René Pfeiffer/ February 2, 2015/ Internet, Security, Stories

At DeepSec 2011 Constantinos Patsakis and Kleanthis Dellios held a presentation titled “Patching Vehicle Insecurities”. They pointed out that the car is starting to resemble more to a computer with mechanical peripherals (incase you haven’t seen their talk,  please do!). This is true for all types, not only the modern cars powered by electricity alone. But there is more. Modern cars are connected to networks (i.e. the Internet or the mobile phone network). This means that your method of transportation is part of the dreaded Internet of Things. Given the design flaws we have seen in talks given at DeepSec, there is no surprise that this is a  breeding ground for major trouble. The Allgemeiner Deutscher Automobil-Club (ADAC), a German motoring association, discovered a lapse in the communication between BMW cars and the servers

DeepSec 2014 Video – “The Measured CSO”

René Pfeiffer/ December 19, 2014/ Discussion, Schedule, Stories

The first recording of DeepSec 2014 has finished post-processing. Just in time for the holidays we have the keynote presentation by Alex Hutton ready for you. Despite its title “The Measured CSO” the content is of interest for anyone dealing with information security. Alex raises questions and gives you lots of answers to think about. Don’t stay in the same place. Keep moving. Keep thinking.

Back from 44CON – Conference Impressions

René Pfeiffer/ September 21, 2014/ High Entropy, Security, Stories

If you haven’t been at 44CON last week, you missed a lot of good presentations. Plus you haven’t been around great speakers, an excellent crew, “gin o’clock” each day, wonderful audience, and great coffee from ANTIPØDE (where you should go when in London and in desperate need of good coffee). Everyone occasionally using wireless connections (regardless if Wi-Fi or mobile phone networks) should watch the talks on GreedyBTS and the improvements of doing Wi-Fi penetration testing by using fake alternative access points. GreedyBTS is a base transceiver station (BTS) enabling 2G/2.5G attacks by impersonating a BTS. Hacker Fantastic explained the theoretical background and demonstrated what a BTS-in-the-middle can do to Internet traffic of mobile phones. Intercepting and re-routing text messages and voice calls can be done, too. Implementing the detection of fake base stations

New Use Cases for Bitcoin

Mika/ May 30, 2014/ Security, Stories

Although I’m new in the Bitcoin world I had a quite promising start. Earlier this month I was able to visit the Bitcoin Conference in Amsterdam and had some very good conversations with core developers from the Bitcoin Foundation and to my honor also the chance to talk to Gavin Andreesen, long-time lead developer and now chief scientist of the Bitcoin Foundation. At DeepSec our first contact with Bitcoin was in 2012 when John Matonis, now Executive Director and Board Member of the Bitcoin Foundation, talked about the evolution of e-Money.  But since then we hadn’t intense contact. Tomorrow I will visit the Bitcoin Expo in Vienna and hope to meet new people in the community and discuss the latest trends and developments. The fascinating thing about Bitcoin and the global block-chain is the

DeepSec 2013 Video: Static Data Leak Prevention In SAP – The Next Generation Of DLP

René Pfeiffer/ February 27, 2014/ Conference, Stories

Leaks are problems you don’t want in your infrastructure. While this is clear for water pipes, it is not so clear for digital data. Copying is a part of the process, and copying data is what your systems do all day. A leak comes into existence when someone without access privileges gets hold of data. The industry has coined the term data leak/loss prevention (DLP) for products trying to stop intruders from ex-filtrating your precious files. Just like other defence mechanisms DLP systems cannot be bought and switched on. You have to know where your data lives, which software you use, what data formats need to be protected, and so on. We invited Andreas Wiegenstein to talk about data loss prevention in SAP systems. His presentation was held at the DeepSec 2013 conference and

DeepSec 2013 Video: Bypassing Security Controls With Mobile Devices

René Pfeiffer/ February 11, 2014/ Conference, Security, Stories

Controls blocking the flow of data are an important tool of defence measures. Usually you need to enforce your organisation’s set of permissions. There are even fancy gadgets available to help you cope with data loss in terms of unauthorised access. This only works in controlled environments. Fortunately the modern IT policy allows intruders to bring their own tools in order to circumvent security controls. Bring Your Own Device (BYOD) is all the fashion these days, and it really helps evading defence mechanisms. At DeepSec 2013 Georgia Weidman of Bulb Security LLC talked about what you can do with mobile devices and what you have to address when protecting your data. „…Companies are putting a lot of faith in these security mechanisms to stop the threats to mobile devices. In this talk we put

DeepSec 2013 Video: Top 10 Security Mistakes In Software (Development)

René Pfeiffer/ February 8, 2014/ Conference, Security, Stories

Everybody makes mistakes. It’s no surprise that this statement applies to software development, too. When you deal with information security it is easy to play the blame game and say that the application developers must take care to avoid making mistakes. But how does software development work? What are the processes? What can go wrong? Answering these questions will give you an insight into ways to avoid being bitten by bugs. Peter af Geijerstam of Factor 10 talked about security mistakes in software development in his presentation held at the DeepSec 2013 conference. We recommend his presentation for everyone dealing with information security, not just software developers.

DeepSec 2013 Video: Trusted Friend Attack – (When) Guardian Angels Strike

René Pfeiffer/ February 6, 2014/ Conference, Internet, Security, Stories

We live in a culture where everybody can have thousands of friends. Social media can catapult your online presence into celebrity status. While your circle of true friends may be smaller than your browser might suggest, there is one thing that plays a crucial role when it comes to social interaction: trust. Did you ever forget the password to your second favourite social media site? If so, how did you recover or reset it? Did it work, and were you really the one who triggered the „lost password“ process? In a world where few online contacts can meet each other it is difficult for a social media site to verify that the person requesting a new password is really the individual who holds the account. Facebook has introduced Trusted Friends to facilitate the identity
