Defence – Beating the Odds with Knowledge

René Pfeiffer/ October 13, 2015/ Conference, Discussion, Mission Statement, Training

When did you write your last business letter? You probably don’t recall, because you write one all of the time. When did you last use ink and paper to do this? If you can’t remember the answer to this question, don’t bother trying. Digital communication is part of our daily life, not only in the business world. We are very accustomed to communicate in the here and now, up to the point where being offline feels unnatural. In turn this means that we are constantly exposed to networks of all kinds, especially the Internet. Our door is open all around the clock. We can’t close it any more, thus openly inviting every kind of threat also using networks. It’s time to seriously think about this. What does it mean? What do we need to

DeepSec 2015 Talk: DDoS – Barbarians at the Gate(way) – Dave Lewis

Sanna/ October 9, 2015/ Conference, Internet, Security

There really is strength in numbers. It’s true for Big Data, high performance computing, cryptography, social media, and flooding the Internet with packets. The latter has been the method of choice for activists, „cyber“ warriors and criminals alike. Network interdiction (as military minds may call it) or Distributed Denial of Service (DDoS) attacks can be hard to counter due to the many sources of the attacking devices. Full pipes are full, no matter what you do. While you can deploy reverse proxies or rely on content distribution networks, the attack still persists. Packets keep coming until the sources are shut down. Flooding someone’s network is not a sophisticated attack. It’s gets the job done, it may be complex by nature, but it is not a stealth exploit sitting in your local network without being

DeepSec 2015 Talk: Extending a Legacy Platform Providing a Minimalistic, Secure Single-Sign-On-Library – Bernhard Göschlberger & Sebastian Göttfert

Sanna/ October 8, 2015/ Conference, Development, Security

Upgrading existing infrastructure and migrating from one architecture to another is often the way to keep your information technology up-to-date. Changing major revisions of software is not for the faint of heart. Many sysadmins sacrificed a good portion of their life force just to jump to the next version. Sometimes you are simply stuck. Code is not always maintained. Products might be obsolete. Developers might have abandoned the project. However the application is still in place and keeps on working. When changes hit this kind of environment, you can’t decline the challenge. Meet the legacy systems that will ruin your day. Bernhard Göschlberger and Sebastian Göttfert have spent thoughts on this problem. They will tell you all about it in their presentation at DeepSec 2015. Well elaborated principles of software engineering foster interoperability between

DeepSec 2015 Workshop: Practical Firmware Reversing and Exploit Development for AVR-based Embedded Devices – Alexander Bolshev & Boris Ryutin

Sanna/ October 7, 2015/ Conference, Training

The Internet of Things (IoT), more common known as the Internet of Stuff, is all around us. You don’t have to wait for it any more. Take a peek at the search results from Shodan and you will see that lots of devices are connected to the Internet. Since your refrigerator does not run high performance hardware, it is well worth to take a look at the hardware being used. For connected household devices and their controllers you need low power equipment. Think small, think embedded, not different. This is why we offer the Practical Firmware Reversing and Exploit Development for AVR-based Embedded Devices training to you at DeepSec 2015. Alexander Bolshev and Boris Ryutin will show you how to create exploits for the Internet of Things: Embedded systems are everywhere. And all of

DeepSec 2015 Workshop: Crypto Attacks – Juraj Somorovsky & Tibor Jager

Sanna/ October 5, 2015/ Conference, Training

Your cryptographic defence can be attacked just as any other barrier you can come up with. Attackers never sleep, you know. Crypto attacks are often facilitated by a simple psychological bias: Since cryptographic algorithms are so complicated (for me), no one can easily figure out how to break them. But this may be true for ASN.1 or Chinese (with apologies to all native speakers, it is meant as a metaphor). The fertile growth of CrypoParties all around the globe documents the interest in using cryptography as a means of protecting data, be it in transit or stored locally. Since you use encryption algorithms every day, regardless if you know about them or

DeepSec 2015 Workshop: Practical Incident Handling – Felix Schallock

Sanna/ October 4, 2015/ Conference, Security, Training

Things go wrong or break, it’s just a matter of time. Ask your sysadmin about this. Apart from wear and tear, there are information security incidents that tend to ruin your perfect day at the office. What happens next? What do you do when noticing that your infrastructure has been compromised? Where do you start? Who needs to be told? Few employees know the answers to these questions. While you might have policies in place that regulate everything one needs to know, the practice looks wildly different. Apart from having a plan, you need to test if your plan works. At DeepSec 2015 Felix Schallock will show you what to do when digital lightning strikes. During two days of training you will take a tour on how to address and handle incidents properly. During

DeepSec 2015 Talk: Continuous Intrusion – Why CI Tools Are an Attacker’s Best Friend – Nikhil Mittal

Sanna/ October 3, 2015/ Conference, Development, Security

In information security pessimism rules. Unfortunately. Extreme Programming might breed extreme problems, too. The short-lived app software cycle is a prime example. If your main goal is to hit the app store as soon and as often as possible, then critical bugs will show up faster than you can spell XCodeGhost. The development infrastructure has some nice features attackers will love and most probably exploit. In his presentation Nikhil Mittal will show you how Continuous Integration (CI) tools can be turned into a Continuous Intrusion. Continuous Integration (CI) tools are part of build and development processes of a large number of organizations. I have seen a lot of CI tools during my penetration testing engagements. I always noticed the lack of basic security controls on the management consoles of such tools. On a default installation, many CI tools

DeepSec 2015 Talk: Visualizing Wi-Fi Packets the Hacker’s Way – Milan Gabor

Sanna/ October 2, 2015/ Conference, Internet

Silent service was the name many submarine services gave themselves. U-boats have the habit of hiding, usually in large bodies of water. How Not To Be Seen remains the prime directive of attackers throughout the age. For the submarines this changed with the introduction of ASDIC and SONAR. You know these technologies from the acoustic sounds of the ping. In the air one often uses radar instead. What do you use for the defence of your wireless networks? At DeepSec 2015 Milan Gabor will show you his idea of Wi-Fi radar, so your IT security admins can become air traffic controllers. Imagine you could see more than console windows from aircrack-ng tools provide. Imagine you could have quick dashboards and deep into more details in short amount of time. And this without writing a

DeepSec2015 Talk: Hacking Cookies in Modern Web Applications and Browsers – a short Interview with Dawid Czagan

Sanna/ October 1, 2015/ Discussion, Interview, Security

You don’t have to be the cookie monster to see cookies all around us. The World Wide Web is full of it. Make sure not to underestimate their impact on information security. Dawid Czagan will tell you why. 1) Please tell us the top 5 facts about your talk. The following topics will be presented: – cookie related vulnerabilities in web applications – insecure processing of secure flag in modern browsers – bypassing HttpOnly flag and cookie tampering in Safari – problem with Domain attribute in Internet Explorer – underestimated XSS via cookie – and more 2) How did you come up with it? Was there something like an initial spark that set your mind on creating this talk? I noticed that cookie related problems are underestimated. People claim, for example, that XSS via cookie requires

DeepSec 2015 Talk: Cryptography Tools, Identity Vectors for „Djihadists“ – Julie Gommes

René Pfeiffer/ September 30, 2015/ Conference, Security, Security Intelligence

Some speak of Crypto Wars 2.0. For others the Crypto Wars have never ended. FBI Directory James Comey does not get tired of demanding back doors to IT infrastructure and devices (there is no difference between back door and front door, mind you). Let’s take a step back and look at the threats. We did this in 2011 with a talk by Duncan Campbell titled How Terrorists Encrypt. The audience at DeepSec 2011 was informed that encryption does not play a major role in major terror plots. What about today? Have terrorists adopted new means of communication? Since the authorities demanding access to protected information do not have statistics readily available, we turned to researchers who might answer this question. Julie Gommes will present the results of studies analysing the communication culture of criminal

DeepSec 2015 Workshop: PowerShell for Penetration Testers – Nikhil Mittal

Sanna/ September 29, 2015/ Conference, Security, Training

The platform you are working with (or against) determines the tools you can use. Of course, everyone loves to boot the operating system of choice and hack on familiar grounds. Occasionally you have no choice, and you have to use what’s available. This is especially true for penetration testing. You get to use what you find on the systems of your digital beachhead. And you are well advised to get familiar with the tools you most definitely will find on these systems. This is a reason to look at the PowerShell. It is available on the Microsoft® Windows platform, so it’s the way to go. In his workshop at DeepSec 2015 Nikhil Mittal will teach you all you need to know about the PowerShell. PowerShell is the ideal tool for penetration testing of a

DeepSec Talk 2015: Cryptographic Enforcement of Segregation of Duty within Work-Flows – Thomas Maus

Sanna/ September 20, 2015/ Conference

Encryption is great. Once you have a secret key and an algorithm, you can safeguard your information. The trouble starts when you communicate. You have to share something. And you need to invest trust. This is easy if you  have a common agenda. If things diverge, you need something else. Thomas Maus will explain in his talk cryptographic methods that can help you dealing with this problem. Meet Alice and Bob, who might not be friends at all. Workflows with segregation-of-duty requirements or involving multiple parties with non-aligned interests (typically mutually distrustful) pose interesting challenges in often neglected security dimensions. Cryptographic approaches are presented to technically enforce strict auditability, traceability and multi-party-authorized access control and thus, also enable exoneration from allegations. These ideas are illustrated by challenging examples – constructing various checks and balances for telecommunications data retention, a vividly discussed

DeepSec 2015 Talk: Legal Responses Against Cyber Incidents – Oscar Serrano

Sanna/ September 19, 2015/ Conference, Security

Like it or not, „cyber“ is here to stay. No matter what word you use, the networks have become a battlefield for various military operations. While you won’t be able to secure physical territory by keyboard (you still need boots on the ground for this), you can gain information, thwart hostile communications, and possibly sabotage devices (given the sorry state of the Internet of Stuff). When you deal  with actions in this arena, you might want to know what your options are. It’s worth to think about legal consequences. When it comes to mundane cyber crime, you usually have laws to deal with incidents. What is the response to a military cyber attack? And what counts as one? In his presentation at DeepSec 2015 Oscar Serrano will introduce you to the legal implications and

DeepSec 2015 Talk: Revisiting SOHO Router Attacks – Jose Antonio Rodriguez Garcia and Ivan Sanz de Castro

Sanna/ September 18, 2015/ Conference, Internet, Security

Have you seen Jon Schiefer’s  film Algorithm? If you haven’t, then you should catch up. The protagonist of the story gain access by using the good old small office / home office (SOHO) infrastructure. The attack is pretty realistic, and it shows that SOHO networks can expose all devices connected to it, either briefly or permanently. Combined with the Bring Your Own Device (BYOD) hype, SOHO networks are guaranteed to contain devices used for business purposes. We haven’t even talked about the security of entertainment equipment or the Internet of Stuff (IoT). Like it or not, SOHO areas are part of your perimeter once you allow people to work from home or to bring work home. Be brave and enter the wonderful world of consumer devices used to protect enterprise networks. José Antonio Rodríguez
