DeepSec 2014 Talk: Why IT Security Is ████ed Up And What We Can Do About It

René Pfeiffer/ November 15, 2014/ Conference, High Entropy

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

New Article for the DeepSec Proceedings Publication

René Pfeiffer/ November 15, 2014/ Conference, Security

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

DeepSec 2014 Talk: The IPv6 Snort Plugin

René Pfeiffer/ November 12, 2014/ Conference, Internet

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. Please tell us the top 5 facts about your talk! Main research for my talk was done in 2011. I am quite surprised (and a little bit frightened) by how little the field of IPv6 security has developed since then. It is often easier to build attack tools than to defend against them. But to improve IPv6 network security we urgently need more detection

DeepSec 2014 Talk: Build Yourself a Risk Assessment Tool

Sanna/ October 29, 2014/ Conference, Interview

„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! There is no problem with understanding existing RA

DeepSec 2014 Talk: Safer Six – IPv6 Security in a Nutshell

René Pfeiffer/ October 20, 2014/ Conference, Internet, Interview

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.

DeepSec 2014 Workshop: Hacking Web Applications – Case Studies of Award-Winning Bugs

René Pfeiffer/ October 14, 2014/ Conference, Training

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

DeepSec 2014 Workshop: Understanding x86-64 Assembly for Reverse Engineering and Exploits

René Pfeiffer/ October 14, 2014/ Training

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

DeepSec 2014 Workshop: Suricata Intrusion Detection/Prevention Training

René Pfeiffer/ September 25, 2014/ Conference, Internet, Training

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

DeepSec 2014 Talk: A Myth or Reality – BIOS-based Hypervisor Threat

René Pfeiffer/ September 24, 2014/ Conference, High Entropy

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

DeepSec 2014 Talk: Why Anti-Virus Software fails

René Pfeiffer/ September 17, 2014/ Conference

Filtering inbound and outbound data is most certainly a part of your information security infrastructure. A prominent component are anti-virus content filters. Your desktop clients probably have one. Your emails will be first read by these filters. While techniques like this have been around for a long time, they regularly draw criticism. According to some opinions the concept of anti-virus is dead. Nevertheless it’s still a major building block of security architecture. The choice can be hard, though. DeepSec 2014 features a talk by Daniel Sauder, giving you an idea why anti-virus software can fail. Someone who is starting to think about anti-virus evasion will see, that this can be reached easy (see for example last year’s DeepSec talk by Attila Marosi). If an attacker wants to hide a binary executable file with a

DeepSec 2014 Talk: Advanced Powershell Threat – Lethal Client Side Attacks

René Pfeiffer/ September 16, 2014/ Conference

Modern environments feature a lot of platforms that can execute code by a variety of frameworks. There are UNIX® shells, lots of interpreted languages, macros of all kinds (Office applications or otherwise), and there is the Microsoft Windows PowerShell. Once you find a client, you usually will find a suitable scripting engine. This is very important for defending networks and – of course – attacking them. Nikhil Mittal will present ways to use the PowerShell in order to attack networks from the inside via the exploitation of clients. PowerShell is the “official” shell and scripting language for Windows. It is installed by default on all post-Vista Windows systems and is found even on XP and Windows 2003 machines in an enterprise network. Built on the .NET framework, PowerShell allows interaction with almost everything one

DeepSec 2014 Talk: Build Yourself a Risk Assessment Tool

René Pfeiffer/ September 10, 2014/ Conference

All good defences start with some good ideas. The is also true for information security. DeepSec 2014 features a presentation by Vlado Luknar who will give you decent hints and a guideline on how to approach the dreaded risk assessment with readily available tools. We have kindly asked Vlado to give you a detailed teaser on what to expect: It seems fairly obvious that every discussion about information security starts with a risk assessment. Otherwise, how do we know what needs to be protected, how much effort and resources we should put into preventing security incidents and potential business disasters? With limited time and budget at hand we’d better know very well where to look first and what matters the most. If we look at some opinion-making bodies in information security, such as ISF,
