|Halvar Flake: Keynote
|CrashTest: Retro-Arcade Hacking
Old school arcade games were awesome on all aspects: games, hardware, piracy, protections. Here is the story of what it took to defeat one of them.
|Ange Albertini and Gynvael Coldwind: Schizophrenic Files – A file that thinks it's many
As file format specs leave room for interpretation and sometimes are misunderstood or ignored by the programmers, some well-formed files may be interpreted inconsistently by different tools and libraries. As a result, this can be (ab)used for simple jokes, anti-forensics or to bypass sanitizers which might lead to data exfiltration.
Ange Albertini: Reverse Engineer, author of Corkami
|Ian Amit: Painting a company red and blue
"Say red team one more time. I dare you. I double dare you.
The term red team has been recently more abused than cyber. And it's making us all hurt in ways we need dolls to point where the bad man touched us. Time to get back to business: In this talk we'll get down and dirty on how a company can actually see a benefit from red teaming. Beyond the red team having fun and bragging rights. Actual ROI. Dirty business speak...

|Endre Bangerter, Ramona Cioccarelli, Beni Urech: Vortessence - Automating memory forensics
Memory forensics is a key technique for detecting and analyzing malware and related attack tools. While there are several memory forensics tools, the Volatility framework is probably the most widely used and significant tool. To detect malware using Volatility, an analyst is typically looking for anomalous system properties. A simple example would be a bogus process name or processes which are started from unusual directories. Stuxnet for instance, introduces two malicious instances of the alleged “lsass.exe” process, which feature a wrong parent process. Another, more subtle anomaly, would be an unusually low or high number of DLLs in a certain process. The key point is that finding these anomalies requires lots of encyclopedic knowledge about the state of a clean Windows system. This knowledge is hard to memorize (for some of us). Moreover, searching for actual discrepancies deviating from the clean state can be a quite boring and a rather mechanical task. Due to laziness and lack of brain capacity we are developing a Volatility based system, dubbed "Vortessence", that automates the process of finding anomalies in memory images. We have tested our system with real world malware samples and the results are encouraging. We believe that Vortessence can be quite useful for practitioners, and we are going to opensource it later in 2014. In this talk we are going to discuss the inner workings of Vortessence, its capabilities, some demos, and future plans.

|Juriaan Bremer und Marion Marschalek: Curing A 15 Year Old Disease
Visual Basic P-code executables have been a pain for a digital eternity and even up until today reverse engineers did not come up with a helpful painkiller. So 15 years after the era of VB6 we present a tool that fully subverts the VB6 virtual machine, thus intercepting and instrumenting the VB P-code in real time. Through dynamic analysis we show that our tool aims at intercepting relevant information at runtime, such as plaintext strings in memory, and which APIs were called. Even more, with our tool an analyst could instrument the execution of byte code on-the-fly, allowing modification of the virtual machine state during execution.

|Rob Fuller: Attacker Ghost Stories: Mostly Free Defenses That Gives Attackers Nightmares
This talk was originally titled “I'm tired of defenders crying”, but thought better of it. This talk is about the tidbits that I've seen piecemeal across the multitude of businesses big and small that were innovated and highly effective, yet free, or mostly free and stopped me dead in my tracks. Going over a number of free, or nearly free methods, tactics, and software setups that will cut down intrusions significantly that you can deploy or start deployment of the hour after the talk is done.

|Stefan Frei: International Vulnerability Purchase Program (IVPP)
The continued discovery of new software vulnerabilities and their abuse by criminals and governments is the root cause of a considerable portion of the losses experienced by society. Every exploitable vulnerability used offensively induces significant direct and indirect losses for users and society as a whole. Experience has shown that traditional approaches based on “more of the same” do not deliver better overall security. It is time to examine the economics of depriving cyber-criminals’ access to new vulnerabilities through the systematic purchase of all relevant vulnerabilities discovered at or above black market prices. Purchasing all vulnerabilities of a software vendor for USD 150k is typically less than 1% of that vendor’s revenue in a year. Purchasing all vulnerabilities for all vendors costs much less than the expected reduction in losses, or less than 0.01% of the GDP of the US or the EU. It is economically viable to make large-scale purchases of vulnerabilities to reduce losses, establish proper incentives, and provide transparency.

|Alexandre Herzog: Why .NET needs MACs and other serial(-ization) tales
"What is the story behind Microsoft's patches MS13-067 (SharePoint) and MS13-105 (Outlook Web Access)? What is really involved in a .NET ViewState and why will Microsoft soon disable the ability to turn off its integrity protection (KB2905247)? What is MS13-100 all about? What was the state of the art of exploiting unprotected ViewState fields before our research? Which new advances did we identify in our research?

|Dave Kennedy: Completely Destroying Education and Awareness Programs
Education and Awareness has become a huge focus for a number of organizations. With the elevated trends around hackers bypassing millions of dollars of technology by simply sending an email or picking up a phone – it has never been easier to own a network. This talk will discuss a lot of the defensive measures we teach our employee population to detect attack and how to circumvent these education controls in order to get into anything. I'll be demonstrating some advanced evasion techniques on getting around some of the most popular technologies such as next generation firewalls, application whitelisting, memory analysis, and more. In this talk we'll turn around everything we are taught, everything we hold sacred, and flip it upside and then destory it with a hammer.

|Raffael Marty: The Heatmap - Why is Security Visualization so Hard?
The extent and impact of recent security breaches is showing that current approaches to prevent these breaches are just not working. But what can we do to protect our business? We have been advocating monitoring for a long time as a way to detect subtle, advanced attacks. However, products have failed to deliver on this promise. Current solutions don't scale in both data volume and analytical insights.

|Evgeny Neyolov: Bitcoins
Bitcoin was one of the hottest topics of the past year. It is decentralized virtual currency based on cryptographic and peer-to-peer protocols and supposed to be anonymous as well as cash money. Without a doubt, bitcoin is the currency of the new age. Despite increased media attention this area is still full of rumors and pitfalls. Important but non-obvious things will be explained in this talk as well as ideas about why a system based on cryptography doesn't mean anonymity by default. It will be shown how to analyze pseudo-anonymous money flaws and how to hide traces. Also, an analysis of famous cases of a cybercrime world (Silk Road, SheepMarketplace) will be presented.
Neyolov Evgeny is a security researcher who is mostly interested in cyber intelligence and enterprise security. His previous conference talks (Hacktivity, BSidesLisbon, Sec-T, Syscan360, Nullcon) cover topics such as forensics, anti-forensics, cybercrime analysis, anti-fraud systems and business applications security.

|Chris Nickerson: 50 Shades of RED: Stories from the "Playroom"
Ever steal a Boeing 777? How about transfer more than $400,000,000 from an account? Have you ever had one of those bad days where one wrong press of the "enter" key accidently broadcasts an emergency message to the radio station asking an entire city to evacuate? The real destruction of a business doesn't come from a shell, a picked lock or a simple lie. The REAL threat is when all of the disciplines are combined and the only thing left in the crosshairs is the BUSINESS itself. Red Teaming is not a process of finding "A" vulnerability, but showing how flaws at EVERY level of the program combine to cause devastating effects to the company (or the tester).
After 15 years in the Red Teaming, Pen Testing and Security Testing Business, I have had some of the weirdest things happen. In this 50 min story time, I plan to go over our methodology, some of our BEST and WORST moments on the job, tips/tricks we picked up along the way and hopefully we can have a few laughs at our (mis)fortune(s).

|Pierre Pronchery: The DeforaOS Project - A journey into Operating System development and related security aspects
Operating System development as it is performed today is probably not headed in the right direction. Instead of simplifying and harmonizing components, the systems we use every day are constantly becoming more complex as extra layers are being added continuously. The Internet as a whole is another visible example of this phenomenon, with the Web and IPv6 equally important parts of the issues at stake. A number of research groups have not only realized and formalized a number of these issues, but are also proposing and developing alternative working solutions. The LANGSEC and Clean-Slate Internet projects are absolutely critical in this context. Working on the DeforaOS Project has allowed me to encounter and understand some of these issues myself. In an effort to take them into account, I am presenting a number of components and principles as they are being designed and implemented for the project, taking some of the results above into account, and demonstrating the first results obtained.
Pierre Pronchery is an IT-Security freelance consultant based in Berlin, Germany. He can also be found promoting Open Source hardware or researching on Clean-Slate Internet and the Internet of Things. The outcome of this work is eventually gathered within the DeforaOS project, an experimental Operating System project. He is also an official NetBSD developer since May 2012 (khorben@).
|Wim Remes: Threat Modeling? It's not out of fashion!
It's been more than a decade since Microsoft brought Threat Modeling to the attention of the broader development and information security audiences. DREAD and STRIDE, combined with interesting side projects like the Elevation of Privileges card game and other assets provided to the community for free remain unused by many. This presentation will not regurgitate what we already know about threat modeling (there's books for that). It will rather provide insight in how security professionals can use and apply threat modeling to effectively build better security. Practical examples will include decomposing a complex software project to reveal vulnerabilities that would otherwise remain unknown, using threat modeling to educate and support developers, applying threat modeling in a penetration testing methodology to enable more efficient scoping. This presentation reveals the often ignored value of threat modeling and enables the audience to apply it in both offensive and defensive security processes.
As a Managing Consultant at IOActive, Wim Remes leverages his 15 years of security leadership experience to advise clients on reducing their risk posture by solving complex security problems and by building resiliency into their organization.

|Marc Ruef: Adventures in a Decade of Tracking and Consolidating Security Vulnerabilities
The talk discusses the approach, possibilities and difficulties that a vulnerability database maintainer is handling. It will offer real-world insight into almost 15 years of vulnerability database management and a database that covers more than 12.000 entries today. The task didn't get any easier as more and more vulnerabilities get published with increasing complexity but much less information is provided in most original advisories. Correlating this data and compiling the best for the users is a complex task that requires a solid processing and a deep understanding of the technical background.
Marc Ruef is co-founder and member of the board at scip AG in Zürich (http://www.scip.ch). The Swiss company provides consulting services covering security testing and forensic analysis, primarily in the financial sphere.

He launched and joined several projects, discussing and improving the broad field of information technology. One of these projects is scip VulDB, a free vulnerability database which is covering more than 12.000 entries since 2003.
|Ruchna Nigam: Android Packers: Separating from the Pack (sponsored)
Android malware has been around for a while now and is significant enough to bypass the "Is Android malware really an issue?" introduction to this abstract.
2014 saw the introduction of the first packer for Android applications.
Android packers were introduced for DRM and with the intention of providing protection for legitimate applications from modifications and tampering.
The flipside of the coin is that the same functionality can be used by malware authors to their advantage, making reverse engineering of malware more difficult for the analyst.
|Raul Siles: iOS: Back to the Future
Apple mobile devices based on the iOS platform implement multiple protection mechanisms and platform restrictions to fulfill several security requirements and support Apple's business model. This presentation focuses on a recently disclosed vulnerability that allows to manipulate a sensitive core default iOS behaviour, which facilitates the exploitation of other vulnerabilities potentially targeting this mobile platform. The design flaw affects the multiple Apple mobile devices (iPhone, iPad, iPad mini..) since iOS version 5 up to the latest iOS version. Although the flaw was discovered in early 2012, it has remained private while researching and evaluating the current vulnerability disclosure models, the real interests of modern vulnerability markets, as well as other vulnerability discovery implications which will also be discussed during the talk.

|Emmanuel Tacheau: The Art of Escape
In this presentation I will talk about targeted attacks and the nature of watering hole attacks. I will cover both these attacks in general, and talk in detail about a specific attack against the Energy and Finance sector. I will examine the various different techniques that can be used by attackers to achieve this goal, as well as the specific techniques used in the Energy and Finance attack. The audience will learn what kinds of websites the attacker compromised and get a deep overview of different mechanisms used by the attacker to succeed in their attack. I will cover the nature of the exploit code that hooks into the victim’s computer as well as the many different mechanisms included into the malware delivered to frustrate analysis and evade detection. Finally, I shall discuss how organizations can protect themselves, and the importance of sharing big data in order to detect these attacks.

|Shahar Tal: I Hunt TR-069 Admins: Pwning ISPs Like a Boss (sponsored)
Residential gateway (/SOHO router) exploitation is a rising trend in the security landscape - ever so often do we hear of yet another vulnerable device, with the occasional campaign targeted against specific versions of devices through independent scanning or Shodan dorking.
We shine a bright light on TR-069/CWMP, the previously under-researched, de-facto CPE device management protocol, and specifically target ACS (Auto Configuration Server) software, whose pwnage can have devastating effects on critical amounts of users. These servers are, by design, in complete control of entire fleets of consumer premises devices, intended for use by ISPs and Telco providers. or nation-state adversaries, of course (sorry NSA, we know it was a cool attack vector with the best research-hours-to-mass-pwnage ratio).
We investigate several TR-069 ACS platforms, and demonstrate multiple instances of poorly secured deployments, where we could have gained control over hundreds of thousands of devices.
