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.
We would like to thank everyone who attended DeepSec 2014! Thanks go to all our trainers and speakers who contributed with their work to the conference!
We hope you enjoyed DeepSec 2014, and we certainly like to welcome you again for DeepSec 2015!
You will find the slides of the presentations on our web site. Some slides are being reviewed and corrected. We will update the collection as soon as we get new documents. The video recordings are in post-processing and will be available via our Vimeo channel. We will start publishing the content soon.
DeepSec 2014 is open. Right now we start the two tracks with all the presentations found in our schedule. It was hard to find a selection, because we received a lot of submissions with top quality content. We hope that the talks you attend give you some new perspectives, fresh information, and new ideas how to protect your data better.
Every DeepSec has its own motto. For 2014 we settled for a quote from the science-fiction film Starship Troopers. The question Would you like to know more? is found in the news sections portrayed in the film. It captures the need to know about vulnerabilities and how to mitigate their impact on your data and infrastructure. Of course, we want to know more! This is why we gather at conferences and talk to each other. We are especially proud to welcome friends and projects that attended DeepSec in the past and return with the results of lively discussions.
Of course, we could also have selected the only good bug is a dead bug for this year’s conference, but we believe this motto should be every day’s motto.
Enjoy DeepSec 2014!
The DeepSec 2014 schedule features a presentation about (hidden) hypervisors in server BIOS environments. The research is based on a Russian analysis of a Malicious BIOS Loaded Hypervisor (conducted between 2007 and 2010) and studies published by the University of Michigan in 2005/2006 as well as 2012/2013. The latter publications discuss the capabilities of a Virtual-Machine Based Rootkits and Intelligent Platform Management Interface (IPMI) / Baseboard Management Controller (BMC) vulnerabilities. Out-of-band management is sensitive to attacks when not properly protected. In the case of IPMI and BMC the management components also play a role on the system itself since they can access the server hardware, being capable to control system resources.
Combining out-of-band components with a hypervisor offers ways to watch any operating system running on the server hardware. Or worse. It’s definitely something you can do without. The researcher investigated the published information and found indications of increased execution times of code running on different hardware. The talk will explain the set-up, the hardware being used, and will introduce a test framework enabling researcher to test (server) hardware for anomalies.
The complete research will be published after the talk in a comprehensive article describing the work. We highly recommend attending the presentation.
Given the many colourful vulnerabilities published (with or without logo) and attacks seen in the past 12 months, one wonders if IT Security works at all. Of course, 100% of all statistics are fake, and only looking at the things that went wrong gives a biased impression. So what’s ████ed up with IT Security? Are we on course? Can we improve? Is it still possible to defend the IT infrastructure?
Stefan Schumacher, director of the Magdeburger Institut für Sicherheitsforschung (MIS), will tell you what is wrong with information security and what you (or we) can do about it. He writes about his presentation in his own words:
Science is awesome. You aren’t doing science in infosec. Why not? Seems to be the overriding message of @0xKaishakunin #AusCERT2014
This was one tweet about my talk of security in a post-NSA age at the AusCert conference in Australia this year. It pretty much sums up my opinion about what is currently going on in the IT Security circus.
Why IT security is ████ed up certainly is a strong stance against what is going on at IT security in general and conferences like DeepSec in particular. However, for the last three to four decades modern IT security exists, we have come a long way in securing our machines, processes and networks. However, certain fields of IT security are thoroughly ignored in research and practical application.
This has to do with computer science being the primary science behind IT security. Computer science is the child of mathematics as a formal science and engineering sciences. This limits the scientific methods to those used in that fields.
Unfortunately, IT security is more than just mathemathics and engineering. Neither social engineering nor human behaviour can be explained with CS methods. Nor can it be combated with it. The same goes for political/policy problems, like intelligence services attacking our human rights in the digital space of living. This is a political problem and we need a political solution for it. So political science also plays a role in IT Security.
When we keep this in mind, we see that current IT security lacks further development in certain fields. So I propose to emancipate IT security research from Computer Science and turn it into a new field of science. We can use the methods and tools of CS, Maths and engineering, but also need the methods, tools and philosophies (!) of humanities and social sciences like psychology and pedagogy.
So lets go and create a new Science. It will be fun and games until theories of science clash.
In cooperation with the Magdeburger Institut für Sicherheitsforschung (MIS) we publish selected articles covering topics of past DeepSec conferences. The publication offers an in-depth description which extend the conference presentation and includes a follow-up with updated information. Latest addition is Marco Lancini’s article titled Social Authentication: Vulnerabilities, Mitigations, and Redesign.
High-value services have introduced two-factor authentication to prevent adversaries from compromising accounts using stolen credentials. Facebook has recently released a two-factor authentication mechanism, referred to as Social Authentication (SA). We designed and implemented an automated system able to break the SA, to demonstrate the feasibility of carrying out large-scale attacks against social authentication with minimal effort on behalf of an attacker. We then revisited the SA concept and propose reSA, a two-factor authentication scheme that can be easily solved by humans but is robust against face-recognition software.
The MIS web site has a collection of all published articles. The full articles will be found in the special edition „In Depth Security – Proceedings of the DeepSec Conferences“.
The deployment of the new Internet Protocol Version 6 (IPv6) is gathering momentum. A lot of applications now have IPv6 capabilities. This includes security software. Routers and firewall systems were first, now there are also plugins and filters available for intrusion detection software such as Snort. Martin Schütte will present the IPv6 Snort Plugin at DeepSec 2014. We have asked him to give us an overview of what to expect.
Martin’s presentation is one of the IPv6 talks we offer at DeepSec 2014. We recommend all IPv6 talks and the IPv6 workshop for anyone dealing with networks, either passively or actively.
„The only advice I might give to everyone who is responsible for information security is that it is never about a tool or a methodology“, says Vlado Luknar. The never-ending quest for the “best” tool or methodology is a futile exercise. In the end it is you, the security specialist, who adds the most value to a risk assessment (RA) / threat modelling process for your company, claims Vlado Luknar (Orange Slovensko a.s. / France Telecom Orange Group). In his talk at DeepSec Mr. Luknar will demonstrate that it is quite easy to capture your overall security knowledge in a home-made, free-of-charge tool. But first, let’s ask Mr. Luknar a couple of questions:
1) Mr. Luknar, please tell us the top 5 facts about your talk!
2) How did you come up with it? Was there something like an initial spark that set your mind on the topic of your talk?
One of key disappointments for me, as a (naive) practitioner, was the fact that no methodology would discover for me something I didn’t have a chance to know about before we started the RA journey. And I don’t mean a forgotten piece of sensitive data, or a server which we discovered when trying to solve the R(asset) = T x V x I formula.
I mean, the real discovery: after you went through all the exercises, responded to all questions, calculated everything that could be calculated, and after you finally pushed that red button labelled START on your mysterious RA machine… The machine then makes few cranky sounds, coughs a couple of times and then finally spits out the ominous verdict:
YOU’VE GOT A BIG RISK OF CLASSIFIED DATA BEING STOLEN, ABUSED OR DISCLOSED!
This is it? Well, yes. Nothing more nothing less.
Then I realized that performing a risk assessment is about the best collective judgment you can make from facts you are able to collect. Only very later on I discovered a very similar statement in the NIST SP 800-39 Managing Information Security Risk.
3) Why do you think this is an important topic?
Despite all that scholars know about risk it remains a vague and somewhat confusing concept. Everybody talks about it, asks for it, but only few know how to go about it, in particular those who really depend on it every day. And then there are those who don’t know that they should depend on it and that it should be an organic part of any security management and not a lifeless requirement from a standard. Done properly it can save you a lot of trouble, done formally you just cheat on yourself.
4) Is there something you want everybody to know – some good advice for our readers maybe? Except for “come to my talk”
The only advice I might give to everyone who is responsible for information security is that it is never about a tool or a methodology.
It is you, the well informed internal expert and the team around you, who add the real value to the process, method or the tool. The tool or the methodology is just a facilitator, although an important one.
5) A prediction for the future – what’s next? What do you think will be the next innovations or future downfalls – for IT-Security in general and / or particularly in your field of expertise?
Some industries have already experienced it, not always handling it properly – that is, the growing pressure of regulation, and the open, public comparison of products based on security. One of the major “conflicts of interests” is that of technological advances versus privacy issues. To me the security is only another attribute of quality (in cases where the product does not directly depend on it) and due to many, mostly economic reasons, it does not yet make it there. The conflict of privacy vs. technology should inevitably make security a native part of any functional and design specifications during standard SDLC. It is not happening yet, especially with traditional business moving to web: just look at companies who provide GPS monitoring or smart home management – how many of them use even SSL and something more than a password on a web page. But it will change very soon.
Data validation threats (e.g. sensitive data, injection attacks) account for the vast majority of security issues in any system, including cloud-based systems. Current methodology in nearly every organisation is to create data validation gates. But when an organisation implements a cloud-based strategy, these security-quality gates may inadvertently become bypassed or suppressed. Everyone relying on these filters should know how they can fail and what it means to your flow of data.
Geoffrey Hill has been in the IT industry since 1990, when he developed and sold a C++ application to measure risk in the commodities markets in New York City. He was recently employed by Cigital Inc., a company that specializes in incorporating secure engineering development frameworks into the software development life-cycles of client organizations. He was leading the software security initiative at a major phone manufacturer and a major central European bank over the course of the last three years.
Currently Geoffrey’s starting up his own security consulting company called Artis-Secure. It is focused on making security development frameworks better integrated with business processes.
As for hobbies apart information security: he’s currently planning a massive fancy-dress gathering next year in an Irish castle. Social engineers, beware! And between all of this he was so kind to answer some questions about the talk his going to give at our upcoming conference…
1. Please tell us the top 5 facts about your talk.
a. The contents will be very useful for enterprise and cloud projects.
b. I will show how the data validation problem is getting increasingly complex.
c. My proposed design uses current technologies.
d. I will describe a validation methodology that is language and process-agnostic.
e. My talk outlines a lightweight and simple solution.
2. How did you come up with it? was there something like an initial spark that set your mind on it?
I have been frustrated by the lack of coherent and concrete validation patterns in my previous projects. I needed to think of a simple way to sanitize and constrain unknown inputs, given the complexities of multiple languages, exceptions and character sets. My talk came out of this.
3. Why do you think this is an important topic?
Data validation threats (e.g. sensitive data, injection attacks) account for the vast majority of security issues in any system, including cloud-based systems. However, the current approach for validation patterns needs to be revisited and simplified or there will be no adoption in the developer community.
4. Is there something you want everybody to know – some good advice for our readers maybe? except for “come to my talk”.
Good security patterns are very useful in a fast moving development environment because they can be easily deployed with minimal disruption. My talk is aimed at fellow security professionals who can use this information.
5. A prediction for the future – what do you think will be the next innovations or future downfalls when it comes to cloud based strategies particularly your field of expertise. Is the cloud here to stay? what’s next?
“Each time history repeats itself, the price goes up”. The ‘Internet of Things’ (IoT) will be driven by new devices and cloud-based operations, making for incredibly complex meta-systems. This complexity will bring with it new security challenges. I believe that many costly mistakes could be made with this next advance in IT. The key to properly addressing these challenges with fewer mistakes is to implement simple models that are based on well-known security patterns. I see the next innovative wave of security as creating and providing standard libraries of these design patterns.
The Internet Protocol Version 6 (IPv6) is the successor to the currently main IP Version 4 (IPv4). IPv6 was designed to address the need for more addresses and for a better routing of packets in a world filled with billions of networks and addresses alike. Once you decide to develop a new protocol, you have the chance to avoid all the mistakes of the past. You can even design security features from the start. That’s the theory. In practice IPv6 has had its fair share of security problems. There has been a lot of research, several vulnerabilities have been discussed at various security conferences. DeepSec 2014 features a presentation called Safer Six – IPv6 Security in a Nutshell held by Johanna Ullrich of SBA Research, a research centre for information security based in Vienna. She answers questions about the content of the talk and the ongoing research in IPv6 security.
Despite the fact that most of the Internet still uses IPv4, don’t forget that IPv6 is widely available by packet tunnels. Modern operating systems have built-in IPv6 connectivity by these tunnels, so the problems discussed in this presentation are not something you have to deal with in the far away future. Therefore we recommend Johanna’s talk for everyone using the Internet.
The World Wide Web has spread vastly since the 1990s. Web technology has developed a lot of methods, and the modern web site of today has little in common with the early static HTML shop windows. The Web can do more. A lot of applications can be accessed by web browsers, because it is easier in terms of having a client available on most platforms. Of course, sometimes things go wrong, bugs bite, and you might find your web application and its data exposed to the wrong hands. This is where you and your trainer Dawid Czagan come in. We offer you a Web Application Hacking training at DeepSec 2014.
Have you ever thought of hacking web applications for fun and profit? How about playing with authentic, award-winning bugs identified in some of the greatest companies? If that sounds like fun, then you should definitely join this workshop! Dawid will discuss bugs that he has found together with Michał Bentkowski in a number of bug bounty programs (including Google, Yahoo, Mozilla and others). You will learn how bug hunters think and how to hunt for bugs effectively. To be successful in bug hunting, you need to go beyond automated scanners. If you are not afraid of going into detail and doing manual/semi-automated analysis, then this workshop is for you.
You will be given a VMware image with a specially prepared environment to play with the bugs. What’s more, after the workshop is over, you are free to take it home and hack again, at whatever pace is best for you. To get the most of this workshop basic knowledge of web application security is needed. You should also have ever used a proxy, such as Burp, or similar, to analyse or modify the traffic.
Dawid is an experienced security researcher who has found security vulnerabilities in products by Google, Yahoo!, Mozilla, Microsoft, Twitter, BlackBerry and other companies. He will lead you through case studies of high profile and high impact flaws in the fabric of software exposed via HTTP(S). Cryptography doesn’t help you if the web logic behaves faulty. The training will show you how web application work, how they can be analysed, and how critical bugs look like. All you need is your laptop and a way to run the provided virtual images.
Assembly language is still a vital tool for software projects. While you can do a lot much easier with all the high level languages, the most successful exploits still use carefully designed opcodes. It’s basically just bytes that run on your CPU. The trick is to get the code into position, and there are lots of ways to do this. In case you are interested, we can recommend the training at DeepSec held by Xeno Kovah, Lead InfoSec Engineer at The MITRE Corporation.
Why should you be interested in assembly language? Well, doing reverse engineering and developing exploits is not all you can do with this knowledge. Inspecting code (or data that can be used to transport code in disguise) is part of information security. Everyone accepts a set of data from the outside world. Most commonly organisations, individuals, and companies consume web pages or receive email. As soon as you deal with filters, you need to worry about code hidden in data. You can get fancy and run an intrusion detection system, too. If you do, then you are in the business of dealing with opcodes – provided you look for exploits in the wild.
The training at DeepSec is especially interesting for penetration testers and everyone involved in defence. Analysing malicious software is a good example that combines defence and reverse engineering with assembly language. You really miss a lot of the things attackers try to tell you, if you don’t speak x86_64! The information gained will also help you to recognise and mitigate attacks. Plus it’s not as hard as you think. Despite x86 assembly having hundreds of special purpose instructions, you will be shown that it is possible to read most programs by knowing only around 20-30 instructions and their variations.
Don’t miss this training! It’s a rare occasion. Take advantage of it!
Once you register don’t forget to bring your laptop, a (Microsoft Visual C++ Express 2012) compiler and a way to run the provided Linux VM.
Apparently some were a little bit disappointed that XSA-108 affects “only” HVM. Sorry, not another catastrophy, not another heartbleed, Shellshock or something in this class. Only a vulnerability which potentially allows access to other VMs.
Anyway, time for an update!
(Idea shamelessly stolen from aloria)
Getting to know what’s going on is a primary goal of information security. There is even a name for it: intrusion detection. And there are tools to do this. That’s the easy part. Once you have decided you want intrusion detection or intrusion prevention, the implementation part becomes a lot more difficult. Well, if you need help with this issue, there is a two-day workshop for you at DeepSec 2014 – the Suricata Training Event.
Suricata is a high performance Network Intrusion Detection System (IDS), Intrusion Prevention System (IPS) and Network Security Monitoring engine. It can serve pretty much all your needs. It’s Open Source (so it cannot be bought and removed from the market) and owned by a very active community. Suricata is managed by the non-profit foundation; the Open Information Security Foundation (OISF). OISF’s mission is to remain on the leading edge of open source IDS/IPS development to meet the ongoing needs of the community.
The two-day training event is held by core developers of Suricata. This means you get all the information on how intrusion detection works, how the rules can be created and adapted to your needs straight from the experts. Attending the workshop will give you not only a greater proficiency in Suricata’s core technology but will also have the unique opportunity to bring questions, challenges, and new ideas directly to Suricata’s developers. You will get the theory plus hands-on exercises with live packets and detection signatures. A sample of topics that will be covered over the course of the 2-day training include:
If you own or use a network, then you should definitely be interested in IDS/IPS – get the packets before the packets get you! The workshop is tailored for developers, technologists, and security professionals. Even if you are new to Suricata or IDS in general, the training is a perfect starting point to get familiar with the topic. Make sure to book early, the number of tickets for all workshops is limited!
Backdoors are devious. Usually you have to look for them since someone has hidden or „forgotten“ them. Plus backdoors are very fashionable these days. You should definitely get one or more. Software is (very) easy to inspect for any rear entrances. Even if you don’t have access to the source code, you can deconstruct the bytes and eventually look for suspicious parts of the code. When it comes to hardware, things might get complicated. Accessing code stored in hardware can be complex. Besides it isn’t always clear which one of the little black chips holds the real code you are looking for. Since all of our devices we use every days runs on little black chips (the colour doesn’t matter, really), everyone with trust issues should make sure that control of these devices is in the right hands – or bytes.
DeepSec 2014 features a talk where BIOS-based hypervisors are discussed. There is ongoing research on this topic. Getting control of a computer’s BIOS or any other part of crucial firmware allows adversaries to either control or at least watch the code a machine is running. Imagine your firmware having an extra layer of virtualisation technology. Usually this is undesirable, especially if an unknown third party is accessing this layer. We asked a well-known Information Security Specialist to present the state of the research regarding these extra features in hardware. The talk will also introduce means to detect hidden hypervisors in firmware and give examples where these modifications were found in the wild. Once attackers go to extra sneaky on the stealth scale, you don’t always get the luxury of detecting backchannel activity. Aliens don’t always phone home, unfortunately.
Everyone using black boxes and computer chips should attend this talk. We know that avoiding unknown firmware and chip designs is hard (hence the term hardware), but you should pay attention to unauthorised modifications of these components. This is crucial if you use the hardware for your own (or someone else’s) infrastructure.
Keep in mind: The materials of this presentation have not been published before, and the research covers a period of more than a year. Drop by and raise your paranoia level! ☺
