DeepSec2016 Talk: Security and Privacy in the Current E-Mobility Charging Infrastructure – Achim Friedland

Sanna/ October 15, 2016/ Conference, Development, Security

The whole information technology strongly depends on electric power. Your servers will turn into expensive door stoppers once the power goes out. The same is true for your mobile devices and the hardware you use to get around. Hence there are efforts to extend the power grid to accommodate the demand of new and emerging technologies. The charging infrastructure requires some security considerations. You cannot simply put a cable into any power socket, throw it our of the windows, and use it for charging unknown devices and vehicles. It’s a bit more complicated. At DeepSec 2016 Achim Friedland will give you an overview on what charging really means. In his talk Achim Friedland focuses on the emerging market of  smart and electric mobility as an interesting area of research and development for both academia and startups.

DeepSec2016 Workshop: Offensive PowerShell for Red and Blue Teams – Nikhil Mittal

Sanna/ October 14, 2016/ Conference, Security, Training

Penetration Tests and Red Team operations for secured environments need altered approaches, says Nikhil Mittal. You cannot afford to touch disks, throw executables and use memory corruption exploits without the risk of being ineffective as a simulated adversary. To enhance offensive tactics and methodologies, PowerShell is the tool of choice. PowerShell has changed the way Windows networks are attacked – it is Microsoft’s shell and scripting language available by default in all modern Windows computers and can interact with .Net, WMI, COM, Windows API, Registry and other computers on a Windows Domain. This makes it imperative for Penetration Testers and Red Teams to learn PowerShell. Nikhil Mittals training is aimed towards attacking Windows networks using PowerShell. It is based on real world penetration tests and Red Team engagements for highly secured environments. We asked Nikhil

Smart Homes are the battlefield of the future – DeepSec Conference examines the Internet of Things

Sanna/ October 14, 2016/ Conference, Internet, Press, Security, Veranstaltung

The Internet of Things is knocking at your door. Many businesses and private individuals have already admitted IoT to their offices and homes, unfortunately often without knowing what they’ve let themselves in for. A naive belief in progress opens all gates, doors and windows to attackers. This is a serious matter. Therefore, DeepSec Conference will focus on this topic on the occasion of its 10th anniversary. The program includes lectures and workshops about the components of smart devices, smart houses and smart networks. Not all products come with a solid security concept. How to test if your devices function properly? What consequences has the total conversion to “smart”? How to proceed correctly to select appropriate systems? Hacked by your fridge Spectacular burglaries have always been the best material for screenplays. We know the scene

DeepSec 2016 Talk: The Perfect Door and The Ideal Padlock – Deviant Ollam

Sanna/ October 14, 2016/ Conference, Discussion, Security

You have spent lots of money on a high-grade pick-resistant lock for your door. Your vendor has assured you how it will resist attack and how difficult it would be for someone to copy your key. Maybe they’re right. But… the bulk of attacks that both penetration testers and also criminals attempt against doors have little or nothing to do with the lock itself! Deviant Ollams talk  will be a hard-hitting exploration (full of photo and video examples) of the ways in which your doors and padlocks – the most fundamental part of your physical security – can possibly be thwarted by someone attempting illicit entry. The scary problems will be immediately followed by simple solutions that are instantly implementable and usually very within-budget. You, too, can have a near-perfect door and acquire ideal

DeepSec 2016 Workshop: Do-It-Yourself Patching: Writing Your Own Micropatch – Mitja Kolsek

Sanna/ October 13, 2016/ Conference, Development, Security, Training

The current state of updating software – be it operating systems, applications or appliances – is arguably much better than it was a decade ago, but apparently not nearly good enough to keep even the most critical systems patched in a timely manner – or at all, says Mitja Kolsek. Official vendor updates are cumbersome, costly to apply, even more costly to revert and prone to breaking things as they replace entire chunks of a product. Enterprises are therefore left with extensive and expensive testing of such updates before they dare to apply them in production, which gives attackers an endless supply of “n-day” vulnerabilities with published exploit code. Furthermore, for various entirely rational reasons, many organizations are using products with no security updates such as old Java runtimes, Windows XP, or expensive industry

DeepSec2016 Talk: Java Deserialization Vulnerabilities – The Forgotten Bug Class – Matthias Kaiser

Sanna/ October 13, 2016/ Conference, Development, Security

Most programming languages and frameworks have support for serialization of data. It’s quite handy for storing things to disk (or other media) and transporting them around a network for example. The process can be reversed, aptly called deserialization, in order to obtain the original pieces of data. Great. Even though this process sounds simple, there is a lot that can go wrong. First of all data can be manipulated. Subtle modifications can cause havoc when the data is touched. There is a lesser known class of bugs around deserialization and serialization techniques. Matthias Kaiser has some insights to share. Java deserialization vulnerabilities are a bug class of its own. Although several security researchers have published details in the last ten years, still the bug class is fairly unknown. Early 2015 Chris Frohoff and Gabriel

DeepSec 2016 Workshop: Fundamentals of Routing and Switching from a Blue and Red Team Perspective – Paul Coggin

Sanna/ October 12, 2016/ Security, Training

Penetrating networks has never been easier. Given the network topology of most companies and organisations, security has been reduced to flat networks. There is an outside and an inside. If you are lucky there is an extra network for exposed services. Few departments have retained the skills to properly harden network equipment – and we haven’t even talked about the Internet of Things (IoT) catastrophe where anything is connected by all means necessary. Time to update your knowledge. Luckily we have just the right training for you! In Paul Coggins’ intense 2 day class, students will learn the fundamentals of routing and switching from a blue and red team perspective. Using hands-on labs they will receive practical experience with routing and switching technologies with a detailed discussion on how to attack and defend the network

DeepSec 2016 Talk: Brace Yourselves – Exploit Automation is Coming! – Andreas Follner

Sanna/ October 12, 2016/ Conference, Development, Security

Automating tasks is not only the domain of system administrators. We use computers for a lot of dull and boring processes. This enhances productivity and enables us to focus on problem solving. That’s good news. The bad news is that your adversaries can do this, too. While there are still more than enough hand-crafted attacks Out There™, there are classes of exploits that follow a certain pattern. So if you want to find out how this auto0wning works, you should listen to the presentation by Andreas Follner. Gone are the days of simple stack smashing and code injection (thanks, DEP / W^X!), says Andreas Follner. Today, return-oriented programming (ROP) is the foundation of exploitation. Most ROP exploits are created as follows: you use a tool to dump all gadgets in a binary to the disk, grep specific

DeepSec2016 Talk: The (In)Security or Sad State of Online Newspapers – Ashar Javed

Sanna/ October 8, 2016/ Conference, Internet, Press

Web sites are simply, one might think. The client requests a page, the server sends it, the layout is applied, and your article appears. This is a heavy simplification. It worked like this back in 1994. Modern web sites are much more complex. And complexity attracts curious minds. Usually that’s what gets you into trouble. Now content management systems serve the web page of the 1990s with a lot of queries, executable code, and from different servers. The ever changing Top 10 list of mistakes from the Open Web Application Security Project can show you the tip of the iceberg. Ashar Javed took a closer look at online newspapers, and he found some scary stuff. The goal of his talk is to raise awareness about the (in)securities of online newspapers. Ashar Javed hopes that their

DeepSec Talk 2016: Inside Stegosploit – Saumil Shah

Sanna/ October 7, 2016/ Conference, Pictures, Security

Stegosploit creates a new way to encode “drive-by” browser exploits and delivers them through image files. Using current means these payloads are undetectable. In his talk Saumil Shah discusses two broad underlying techniques used for image based exploit delivery – Steganography and Polyglots. Drive-by browser exploits are steganographically encoded into JPG and PNG images. The resultant image file is fused with HTML and Javascript decoder code, turning it into an HTML+Image polyglot. The polyglot looks and feels like an image, but is decoded and triggered in a victim’s browser when loaded. This talk focusses more on the inner mechanisms of Stegosploit, implementation details and how certain browser specific obstacles were overcome. The Stegosploit Toolkit contains the tools necessary to test image based exploit delivery. A case study of a Use-After-Free memory corruption exploit (CVE-2014-0282) shall

DeepSec 2016 Talk: Social Engineering The Most Underestimated APT – Hacking the Human Operating System – Dominique C. Brack

Sanna/ October 5, 2016/ Conference, Security

Social Engineering is an accepted Advanced Persistent Threat (APT) and is going to stay according to Dominique C. Brack of the Reputelligence, Social Engineering Engagement Framework (SEEF). Most of the high-value hacking attacks include components of social engineering. Understanding the behind the scene methods and approaches of social engineering will help you make the world a safer place. Or make your attack plans more successful! Social Engineering is a topic that does not really fit into technical hacking and is also underestimated by security professionals. There are no tools or hardware you can buy to prevent Social Engineering attacks. But Social Engineering is an APT to be taken seriously, because most attacks consist partly of it and its attack execution and prevention needs training and skills. Social Engineering has progressed and professionalized more than you think. It is disastrously effective.

DeepSec2016 Talk: Behavioral Analysis from DNS and Network Traffic – Josh Pyorre

Sanna/ October 4, 2016/ Conference, Internet, Security

What’s in a name? A rose? The preparation for an attack? Or simply your next web page you will be looking at? The Domain Name System (DNS) has gone a long way from replacing text lists of hosts to a full directory service transporting all kinds of queries. DNS even features a security protocol for cryptographically signed zone data. In order to balance the load, name resolution has caches that temporarily store DNS information. Usually organisations run their own DNS resolvers as caches for their infrastructure. Even if it’s just a flat network with local clients all DNS requests are channelled to hit your resolvers. Before applications open a data connection, they will query the local resolver to get address data or other hints on how to contact the other endpoint of the communication.

DeepSec2016 Talk: Cover Your SaaS: Protecting Your Cloud With Analytics and Machine Learning – Ian Thornton-Trump

Sanna/ September 24, 2016/ Conference, Security, Security Intelligence

Some people call military intelligence an oxymoron. This usually happens when something goes wrong. It might be due to sloppy reconnaissance, operations, or simply bad luck. While it’s always good to have someone or something to blame, things are not so easy in modern „cyberspace“. Improving your security means to have something to base this improvement on. Despite the fact that being lucky is never a bad thing, the selection of your defences and the assessment of the threats you are facing need to be based on something more solid. IT departments have been mining logs and other kind of raw materials that produce metrics for decades. Every once in a while there is a new trend. Now that we can store enormous amounts of data and can access it, we have a lot

DeepSec 2016 Talk: Fuzzing Remote Interfaces for System Services in Android – Alexandru Blanda

Sanna/ September 23, 2016/ Conference, Security

When in doubt, go for the core. This statement is true for most Star Wars films. It is also valid for any kind of security research. Modern software has tons of dependencies, metric or otherwise. In addition, most platforms provide a set of basic components accessible by API. The wheel has been invented already. So if you look for weaknesses, addressing these fundamentals is a good idea. Why start at the outer shell, when you can directly go to the foundation of the walls. Siege warfare used to be like that. What happens when you combine the technique of fuzzing with accessible interfaces will be explained by Alexandru Blanda in his presentation at DeepSec 2016. System services represent one of the core components in Android, implementing many fundamental Android features such as media playback,

DeepSec 2016 Talk: Malicious Hypervisor Threat – Phase Two: How to Catch the Hypervisor – Mikhail A. Utin

Sanna/ September 22, 2016/ Conference, Security

The blue/red pill analogy has been used a lot when it comes to hypervisor security and virtualisation. While there are reliable ways to determine if your code runs in a hypervisor or not, the underlying problem still persists. How do you know if the platform your code runs on watches every single move, i.e. instruction or data? Given the discussion of backdoors in hardware, this threat is real. Mikhail Utin discussed his findings at DeepSec 2014. He discovered manipulation of the BIOS in certain server systems. The hardware was probably affected, too. Two years later he presents his research covering the detection of malicious hypervisors in parts of your infrastructure where they should not be. Utilizing the definition of vulnerability as “inability to resist a threat” we want to update our consideration of three
