Hacking US Traffic Control Systems
Abstract: Probably many of us have seen that scene from "Live Free or Die Hard" (Die Hard 4) were the "terrorist hackers" manipulate traffic signals by just hitting Enter key or typing a few keys, I wanted to do that! so I started to look around and of course I couldn't get to do the same, that's too Hollywood style! but I got pretty close.
I found some interesting devices used by traffic control systems on important cities such as Washington DC, Seattle, New York, San Francisco, Los Angeles, etc. and I could hack them :) I also found that these devices are also used in cities from UK, France, Australia, China, etc. making them even more interesting.
This presentation will tell the whole story from how the devices were acquired, the research, on site testing demos (at Seattle, New York and Washington DC), vulnerabilities found and how they can be exploited, and finally some possible NSA style attacks (or should I say cyberwar style attacks?) Oh, I almost forgot, after this presentation anyone will be able to hack these devices and mess traffic control systems since there is no patch available (sorry didn't want to say 0day ;)) I hope that after this I still be allowed to enter (or leave?) the US.

SQL Injections to MIPS Overflows: Part Deux
Abstract: A while back, I showed how to combine SQL injection vulnerabilities with MIPS Linux buffer overflows in order to pop root on Netgear SOHO routers. I decided to revisit the "ReadyDLNA" UPnP server that ships on nearly all Netgear routers, to see what has changed since then. Short version: a lot and not so much.
There have been changes in Netgear's code that seem to target the classes of vulnerabilities I demonstrated previously. Raising to the challenge, I wanted to see if I could find a fresh, new SQL injection and buffer overflow that I could once again pair up to get root. While I wasn't disappointed, the code has gotten even gnarlier, which is saying a lot. Graceful exploitation without crashing was even more complicated than before.
In this talk I describe describe changes Netgear has made to the DLNA server in hopes of reduced pwnage, and why they didn't work. I'll describe some techniques for statically and dynamically analyzing binaries unpacked from SOHO router firmware. I'll tell a story of exploiting unadvertized SOAP actions and masquerading as a popular brand of television on the way to root prompt nirvana. Exploitation of buffer overflows on MIPS still hasn't seen a lot of public discussion, so I'll go into that as well. Of course, as they say, root or it didn't happen. If, like me, you want to see a live demo on real gear, I won't disappoint. Demos are my favorite part of any talk.

Researching Android Device Security with the Help of a Droid Army
Abstract: In the last few years, Android has become the world's leading smart
phone operating system. Unfortunately, the diversity and sheer number
of devices in the ecosystem represent a significant challenge to
security researchers. Primarily, auditing and exploit development
efforts are less effective when focusing on a single device because
each device is like a snowflake: unique.
This presentation centers around the speaker's approach to dealing with the Android diversity problem, which is often called "fragmentation". To deal with the issue, Joshua created a heterogeneous cluster of Android devices. By examining and testing against multiple devices, you can discover similarities and differences between devices or families of devices. Such a cluster also enables quickly testing research findings or extracting specific information from each device.
When you leave this presentation, you will understand why the diversity problem exists and how to tackle it by creating a cluster of your own. Joshua will show you how to build such a cluster, provide a set of tools to manage one, and show you all the ways to leverage it to be more successful in your auditing and exploit development tasks.

Other notable accomplishments include exploiting Oracle's JVM for a win at Pwn2Own 2013, successfully compromising the Android browser via NFC with Georg Wicherski at BlackHat USA 2012, and winning the DefCon 18 CTF with the ACME Pharm team in 2010.
Legacy Sandboxing: Escaping IE11 Enhanced Protected Mode
Abstract: In June 2013 Microsoft started the first of their new bug-bounty programs, focusing on finding vulnerabilities in IE11 on the upcoming Windows 8.1 OS. Rather than spending my time fuzzing for RCEs I instead focused on pure logic bugs and the best place to find them was in the sandbox implementation. As IE11 defaults to using Microsoft’s new Enhanced Protected Mode (EPM) sandbox that repurposes Windows 8’s App Container mechanism to more heavily restrict access to securable resources it would seem to be a tough challenge, but it turned out not to be the case.
This presentation will fully detail 4 sandbox escapes I discovered during the 30 day bug bounty period, some which have been present since Vista and IE7. Each one has a different root cause; none requiring any memory corruption or kernel vulnerabilities. I’ll also given a bit of background about how I found these issues, how to start probing the IE sandbox attack surface and some interesting behavior in the way EPM is implemented which might lead to further vulnerabilities being discovered.

Ghosts of Christmas Past: Fuzzing Language Interpreters using Regression Tests
Abstract: In this talk I will discuss an approach to fuzzing language interpreters that
has found a large number of bugs over the past few months, across a number of
Taking inspiration from previous work , this approach makes use of existing regression tests to provide information on language syntax, semantics, and API usage. From there, it employs a variety of different mutation and generation strategies to produce new inputs that are, ideally, syntactically valid, semantically complex, and, even more ideally, break the interpreter in new and interesting ways.
During the talk I will cover three primary extensions over earlier research:
* The combination of standard reference crawling fuzzing  with regression test based fuzzing
* A comparison of multiple approaches to input generation using regression tests - from the direct application of tools like Radamsa , to mutation and combination using language grammars, to the use of on-the-fly reflection to crawl for reference counting issues.
In the interest of self-flagellation, I will also discuss a few tragic failures of both intellect and implementation that occurred along the way.

A Curious Cyber War: Business Owners vs Investors
Abstract: This presentation will discuss recent market and valuation trends of offensively-focused cyber companies. The audience will be exposed to an unvarnished look at the financial condition of the sector and its (in)ability to stand up to the inescapable recapitalization (re-tooling) required to compete in a post-Snowden environment. Yet, we have witnessed a mixed response, reluctance, and skepticism from the investment community to fund these activities—resulting in a valuation gap with business owners. We will examine the main drivers of this schism and offer suggested catalysts to break the logjam and swiftly innovate next generation solutions.

Matthias Luft & Felix Wilhelm
Abstract: In this presentation we will describe our research on the architecture and security of the Hyper-V hypervisor and its role in the Microsoft Azure cloud. Besides a deeply technical discussion of the hypervisor implementation and its attack surface, we will show how we discovered MS13-092 a vulnerability that allows permanent DoS of the hypervisor and the potential compromise of other VMs on the same host.
We will describe the challenges involved in reversing, debugging and understanding an hypervisor and plan to release several tools, IDA scripts and POCs we developed as part of our research.
Our presentation shows that even seemingly bullet proof software still contains critical bugs and we hope to motivate more researchers to start active research inso hypervisor security in general and especially Hyper-V.
Bio: Matthias and Felix are security researchers at ERNW, they are specialized in testing and breaking complex IT environments. Together they performed an extensive research project on the security of a leading cloud provider, which resulted in the discovery of multiple vulnerabilities including MS13-092.

Fuzzing, Reversing and Maths
Abstract: We want to presentate several 0days using fuzzing and reverse engineering
and maths. 1 Critical remote 0day in an EMC application. 2 Critical remote
0day in a novosoft famous backup application.The main idea is to present
0days found by us and this 0days are not typical, are different, specially
one of them which implies protocol/binary reverse engineering and complex
maths and show to the audience how other kind of vulnerabilities can be
We think that the idea of presenting different kind of 0days, which are critical, and explain how to discover this kind of vulnerabilities can be really interesting for the audience and they will have a new perspective in application security.
In our research in these last months we were searching vulnerabilities in important backup servers applications.We were using reverse engineering and fuzzing and we found different kind of vulnerabilities which are really interesting.
1-The critical remote 0day in the EMC application is really interesting, found with reversing engineering the protocol and the binary files and it was necessary to apply some mathematics in order to understand the vulnerability and we had to implement some mathematics algorithms in order to exploit the vulnerability.It's a different vulnerability, it's not the typical buffer overflow, heap overflow, etc, and we want to show to the audience how we found this vulnerability and show how this kind of vulnerabilities can be found.
2- The 0days of the other backup application, were found with protocol fuzzing. Both of the 0days are critical and interesting, one is an authentication bypass to the backup server and the other 0day is a "permament" denial of service which is really curious and funny.Our idea is to show how we found both vulnerbilities and show how this kind of vulnerabilities can be found with protocol fuzzing.

Analytics, and Scalability, and UEFI exploitation! Oh My!
Abstract: We use UEFI and commodity PC manufacturer "firmware" as a use case for
vulnerability discovery and exploit development powered by analytics.
BIOS, UEFI, and embedded firmware are recent focus areas for
vulnerability analysis and exploit research. There are great
offensive-security presentations and research on ring < 0 rootkits,
failed implementations of trusted computing concepts, and
This talk complements existing firmware research by applying data-science to UEFI code analysis. This does not attack the UEFI platform or secure boot implementations; it does consider UEFI applications, drivers, and associated environments as attack surface. Analytics of code-usage, features, pervasiveness, update frequency, and vulnerabilities will help determine viability of homogeneous exploit development for seemingly-heterogeneous environments. The talk will review data-science approaches to vulnerability discovery in UEFI code, demonstrate the scalability of UEFI exploitation, and explore the potential for persistence as well as similar fun exercises.
Code and frameworks for replicating the approach will be released, unfortunately vulnerabilities cannot accompany, but hopefully demos will suffice.

Digital Rights Management for Malicious Software
Abstract: To process and extract intelligence from large volumes of suspect
executables collected in networks each day, numerous automated malware
analysis systems (now represented by various threat detection
appliances and multi-billion dollar companies) have been created. In
an effort to avoid detection and increase time on target, malware
authors have designed, developed and commoditized analysis environment
detections. In response, researchers and practitioners have sought to
make an analysis environment look like a normal system (e.g., via
baremetal malware analysis). Such responses often enable a successful
automated analysis because the instrumentation and virtual
machine-detection techniques employed by malware represents a model
that is fundamentally brittle and hence easily defeated.
In this presentation I introduce techniques that, if widely adopted by malware authors, would permanently disadvantage automated analysis systems. To do so, I explore the ramifications of inverting the canonical approach to preventing a sample's execution in an analysis environment. That is, instead of examining techniques that detect specific malware analysis sandboxes or virtualization containers, I consider malicious software that will fail to execute correctly on any environment other than the originally compromised system.
To better understand the details of "digital rights management" for malicious software, I present a design of anti-analysis techniques that make the successful execution of a malware sample dependent on the unique properties that identify the originally infected host. To highlight the relevance of this idea's application by malware authors, I discuss both common and targeted malware instances' (e.g., Flashback, Gauss) use of conceptually similar techniques to prevent automated analysis of their samples.

Fun Attacks Using a Compromised Random Number Generator
Abstract: Many information security systems rely on cryptographic schemes that need truly random numbers be secure. In recent months there have been several high profile news stories about weaknesses or potential compromises in both software and hardware random number generators. A compromised random number generator is difficult to catch because it can output random looking data that is predictable to an attacker only.
In this talk I describe how to go from knowledge of a weakness in a random number generator to a full security compromise. We will look at examples including how to fully decrypt a TLS stream, how to compromise a bitcoin wallet by looking at the ECDSA signatures on the public block chain, how to factor improperly generated RSA keys and more.
