  UEFI BIOS holes: So Much Magic, Dont Come Inside
 Alexander Ermolov
  This report introduces the topic of the vulnerability searching process in the firmware of GA-Q170M-D3H motherboard. It also describes how the CPU level debugger can be obtained with the help of Intel DCI technology at home. Detailed information on how to operate with the debugger will also be provided. We will tell how Intel DCI was used to detect the vulnerability common for all types of motherboards. In addition, we will demonstrate how to exploit the very same vulnerability in Intel NUC Kit NUC7i3BNH despite this vulnerability has been patched.

  Betraying the BIOS: Where the Guardians of the BIOS are Failing
 Alex Matrosov
  For UEFI firmware, the barbarians are at the gate -- and the gate is open. On the one hand, well-intentioned researchers are increasingly active in the UEFI security space; on the other hand, so are attackers. Information about UEFI implants -- by HackingTeam and state-sponsored actors alike -- hints at the magnitude of the problem, but are these isolated incidents, or are they indicative of a more dire lapse in security? Just how breachable is the BIOS?

In this presentation, I'll explain UEFI security from the competing perspectives of attacker and defender. I'll cover topics including how hardware vendors have left SMM and SPI flash memory wide open to rootkits; how UEFI rootkits work, how technologies such as Intel Boot Guard and BIOS Guard (and the separate Authenticated Code Module CPU) aim to kill them; and weaknesses in these protective technologies. There are few public details; most of this information has been extracted by reverse engineering.
  Alex Matrosov is a Principal REsearch Scientist at Cylance. He has over a decade of experience with reverse engineering, advanced malware analysis, firmware security, and advanced exploitation techniques. Before joining Cylance, Alex served as Principal Security Researcher at Intel Security Center of Excellence (SeCoE) where he lead BIOS security for Client Platforms. Before this role, Alex spent over six years at Intel Advanced Threat Research team and ESET as Senior Security Researcher. He is also author and co-author of the numerous research papers and the book "Rootkits and Bootkits: Reversing Modern Malware and Next Generation Threats". Alex is frequently invited to speak at security conferences, such as REcon, Ekoparty, Zeronigths, Black Hat and DEF CON. Also, he is awarded by Hex-Rays for open-source plugin HexRaysCodeXplorer which is developed and supported since 2013 by REhint's team.

 

 

  Hacks & Case Studies: Cellular Devices
 Butterly & Schmidt
  Hacking is fun and so are learning and playing with new things, as such the choice of utilizing my small GSM network for research was trivial. Having seen various approaches for cellular communications in previous projects, I decided to start collecting connected devices "just to have a closer look". As the title already announces, the talk will cover various devices and shed light on how they communicate with the rest of the world. It will show how each one can be remotely controlled and which reporting channels are in use. Where possible simple hacks will show how most identified security measures can be circumvented and what this can mean for the operator/user of the device. To do so we'll be bringing a few devices like a GPS tracker/vehicle immobilizer live on stage together with our testing setup. Every single case study helps creating a bigger picture of cellular communications - how they work, how they're secured and how they can be broken.
  Brian is a security researcher, analyst and simply a hacker at Heidelberg (Germany) based ERNW GmbH. Coming from the field of electronic engineering he tends to choose alternate approaches when hitting new projects. He currently works on the intersection of embedded-, mobile and telco-security, with tasks and research ranging from evaluating apps and devices through to analyzing their transport networks and backend infrastructures. Resulting from the broad range of practical experience and natural curiosity he has developed a very diverse set of skills and knowledge. He enjoys cracking open black boxes and learning about their details down to the electronic circuits and creating the tools he needs on the way. He is always happy to share his knowledge and findings.

Hendrik Schmidt is a seasoned security researcher with vast experiences in large and complex enterprise networks. He is a pentester at the German based ERNW GmbH with focus on telecommunication networks. Over the years he evaluated and reviewed all kinds of network protocols and applications. He loves to play with complex technologies and networks and demonstrated several implementation and design flaws.

  Parasite OS
 Gustavo Scotti
  Typically, post-exploitation is an intelligence game. Accessing any of the host operating system resources exposes the attacker to defensive systems. Still relying on execve/ProcessCreate family to run your arsenal? It’s time to review your concepts. Parasite OS is a rogue operating system to manage its own tiny resources (memory, IO, CPU) on top of the host operating system. Starting with the simplest process management, it can run on a single and unique thread at user mode, managing multiple rogue processes (no rootkit required to hide your processes).
  Gustavo Scotti (aka csh): did some cool stuff in the security space - including the infamous tsl-bind exploit, PS2 reverse engineering, and the Axur05 e-zine. Software engineer at Microsoft, worked from Xbox One's secure boot, content protection, and anti-piracy to cryogenic computing research. Currently playing with FPGA in data centers.

  DIYBio community helping SUS
 Janine Medina a.k.a. Nina Alli
  Brasil has one of the first single payor medical systems (Sistema Único de Saúde, SUS) in the world. In such a large and diverse country, the system is faced with different obstacles (difficult terrain, lack of medical personnel, equipment, and funding). This is where I believe the DIYBio community can help - we have come up with new ways to get care to patients that is less expensive, easy to produce, and can be handled by the patient to send in for care management. I will discuss ways that the Brasilian system can teach the rest of the world how to make a single payor system successful with citizen scientists at its core.
  Nina Alli is the Project Manager of the DEF CON BioHacking Village and works in biomedical and health engineering as well as information security research.

 Luckas Faria
  Considerando o mundo Open-Hardware e Open-source muito tem-se evoluído nos últimos tempos, isto graças ao barateamento da tecnologia o que tem feito que FPGAs tenham ficado cada vez mais acessíveis. Outra tecnologia que tem popularizado é FPGAs SOC (com uma interface CPU + FPGA, as vezes até no mesmo chip) o que tem ajudado muito no processo de teste e desenvolvimento dos módulos em hardware por uma interface de comunicação mais facilitada. Assim, nesta palestra, consideraremos estes recursos de desenvolvimento e guiaremos o processo de construção do nosso Cripto Hardware tendo como alvo estruturas de curvas elípticas criptográficas. Dentro desta implementação abordando dois aspectos, um com a máxima segurança e outro com o máximo throughput.

  50 Shades of Visual Studio
 Marion Marschalek
  Compilers can do ugly things to binary code, we know that, but how ugly does it get when one tries to visualize this? With the help of disassembly tools we can look at the function layout, but also at the actual instructions of compiled binaries. How fun would it be though, if we could look, instead of at individual instructions and functions, at all instructions at the same time? This talk will explore visualization methods applied to distributions of individual instructions and different classes of instructions within Visual Studio compiled binaries, to make it easy for analysts to find things such as encryption or compression algorithms, to distinguish different binary packers; but also to find differences in compiler optimization measures applied to one and the same code base. This kind of visualization helps finding out, how much Visual Studio alters code when applying certain optimization options for compilation. Besides fun, the resulting images are also quite beautiful, just saying. The visualizations presented are fully generated relying on open source tools, such as r2graphity, Gephi and D3JS.
  Marion Marschalek is a former malware analyst and reverse engineer, who recently started work at Intel in order to conquer the field of low level security research.

  Medical records black market value
 Matias Katz
  Medical record breaches have a double impact, since they harm the healthcare institutions, but also disclose private and sensitive information about the patients. Because of this, the value of EHR (Electronic Health Records) has exceeded the value of financial records, not only because it opens the door for liability actions, but also because it can damage (or ruin) the patients life.

In this talk I will cover the different ways in which an owned server could be taken advantage of for profit purposes, and then I will discuss about the sell value of medical and financial information in the black market. I will cover a few specific recent cases (like the last one from Equifax), describe the attack vector, calculate how much it cost to the companies and end users, and talk about how it could have been fixed.

  Penetration Testing in DevOps Environments
 Matthias Luft
  Everyone has heard of Docker, Kubernetes, etcd, CI/CD -- and many other technologies that own a .io domain. More importantly, those technologies are now starting to be used in enterprise environments which also want to leverage potential development and deployment benefits. These potential benefits partly originate from the approach of the technologies to move complexity (like handling of logging or network architecture) down from the application into the platform, consequently making the platform more complex. This complexity on the one hand increases the likelihood for technical or logical vulnerabilities and misconfiguration, but on the other hand also makes it more difficult for researchers and penetration testers to approach it from a security perspective due to a steep learning and curve and setup requirements. In this presentation, we want to explain Docker, Kubernetes, overlay networking concepts, and supporting services from a penetration tester perspective and describe (anonymously) common vulnerabilities and misconfigurations we found in various environments (but not necessarily in the tools/platforms/technologies) itself.
  Matthias Luft is a security researcher and one of the CEOs of the German security company ERNW. He is interested in a broad range of topics (such as DLP, virtualization, and network security) while keeping up with the daily consulting and assessment work.

 

 

  Porosity A Decompiler For BlockchainBased Smart Contracts Bytecode
 Matt Suiche
  Ethereum is gaining a significant popularity in the blockchain community, mainly due to fact that it is design in a way that enables developers to write decentralized applications (Dapps) and smart-contract using blockchain technology.

Ethereum blockchain is a consensus-based globally executed virtual machine, also referred as Ethereum Virtual Machine (EVM) by implemented its own micro-kernel supporting a handful number of instructions, its own stack, memory and storage. This enables the radical new concept of distributed applications.

Contracts live on the blockchain in an Ethereum-specific binary format (EVM bytecode). However, contracts are typically written in some high-level language such as Solidity and then compiled into byte code to be uploaded on the blockchain. Solidity is a contract-oriented, high-level language whose syntax is similar to that of JavaScript. This new paradigm of applications opens the door to many possibilities and opportunities. Blockchain is often referred as secure by design, but now that blockchains can embed applications this raise multiple questions regarding architecture, design, attack vectors and patch deployments.

As we, reverse engineers, know having access to source code is often a luxury. Hence, the need for an open-source tool like Porosity: decompiler for EVM bytecode into readable Solidity-syntax contracts - to enable static and dynamic analysis of compiled contracts.
  Matt Suiche is recognized as one of the world's leading authorities on memory forensics and application virtualization.

He is the founder of the United Arab Emirates based cyber-security start-up Comae Technologies. Prior to founding Comae, he was the co-founder & Chief Scientist of the application virtualization start-up CloudVolumes which was acquired by VMware in 2014. He also worked as a researcher for the Netherlands Forensic Institute.

His most notable research contributions enabled the community to perform memory-based forensics for Mac OS X memory snapshots but also Windows hibernation files.

  Firmware is the new Black: Analyzing Past Three Years of BIOS&UEFI Security Vulnerabilities
 Rodrigo Branco
  In recent years, we witnessed the rise of firmware-related vulnerabilities, likely a direct result of increasing adoption of exploit mitigations in major/widespread operating systems - including for mobile phones. Pairing that with the recent (and not so recent) leaks of government offensive capabilities abusing supply chains and using physical possession to persist on compromised systems, it is clear that firmware is the new black in security. This research looks into BIOS/UEFI platform firmware, trying to help making sense of the threat. We present a threat model, discuss new mitigations that could have prevented the issues and offer a categorization of bug classes that hopefully will help focusing investments in protecting systems (and finding new vulnerabilities). Our data set comprises of 90+ security vulnerabilities handled by Intel Product Security Incident Response Team (PSIRT) in the past 3 years and the analysis was manually performed, using white-box and counting with feedback from various BIOS developers within the company (and security researchers externally that reported some of the issues - most of the issues were found by internal teams, but PSIRT is involved since they were found to also affect released products).

  Content Security Policy: Is It Dead Yet?
 Sergey Shekyan
  Content Security Policy (CSP) is an 8 year old browser feature that helps fighting content injections. While an average web surfer most likely loads a page that employs CSP several times a day (thanks to the big dudes), overall adoption is still not perfect.

In this presentation, we will go over the evolution of CSP, browser support levels, caveats and mistakes in deploying an effective policies. We will focus on latest big changes in the specification that should ease the deployment process dramatically, including how to make violation reports useful.

Last but not least we will discuss what is still not covered by the CSP and how it can be abused.

  Keynote: Attacks on encrypted memory: Beyond the single bit conditionals
 Shay Gueron
  Protecting users's privacy in virtualized cloud environments is an increasing concern for both users and providers. A hypervisor provides a hosting facility administrator with the capabilities to read the memory space of any guest VM. Therefore, nothing really prevents such an administrator from abusing these capabilities to access users' data. This threat is not prevented even if the whole memory is encrypted with a single (secret) key. Guest VM's can be isolated from the administrator if each guest VM has its memory space encrypted with a unique per-VM key. Here, while the hypervisor's memory access capabilities remain unchanged, reading a VM memory decrypts the VM's encrypted data with the wrong key and therefore gives no advantage to the attacker. This is indeed the motivation behind some newly released technologies in latest processors.

However, this talk argues that the privacy claim of any technology that uses different encryption keys to isolate hypervisor administrators from guest VM's cannot be guaranteed. To show this, it demonstrates a new instantiation of a 'Blinded Random Block Corruption (BRBC) Attack. Under the same scenario assumptions that the per-VM keying method addresses, the attack allows a cloud provider administrator to use the capabilities of a (trusted) hypervisor in order to login to a guest VM (besides the encrypted memory). This completely compromises the user's data privacy. Furthermore, we also demonstrate that even non-boolean values can be effectively targeted by attackers, forcing the elevation of privileges of a process running in a protected VM as demonstration.

This shows, once again, that memory encryption by itself, is not necessarily a defense-in-depth mechanism against attackers with memory read/write capabilities. A better guarantee is achieved if the memory encryption includes some authentication mechanism.

  Deobfuscating malware with logic: The use of SMT solvers in the IT Security
 Thais Moreira Hamasaki
  IT security is becoming increasingly important to protect company assets. Analysis tools help analysts identifying vulnerabilities and issues before they cause harm downstream. Understanding how software and hardware can be secured using tools and techniques beyond standard debuggers ensures higher security and integrity. This talk is about the applications of SMT solvers in IT security and how I use them to analyze malicious binaries. (WiP)
