1. GOD MODE Unlocked: Hardware backdoors in x86 CPUs

Speakers: 

Christopher Domas, Cyber Security Researcher

Complexity is increasing. Trust eroding. In the wake of Spectre and Meltdown, when it seems that things cannot get any darker for processor security, the last light goes out. This talk will demonstrate what everyone has long feared but never proven: there are hardware backdoors in some x86 processors, and they're buried deeper than we ever imagined possible. While this research specifically examines a third-party processor, we use this as a stepping stone to explore the feasibility of more widespread hardware backdoors.

2. Project “The Interceptor”: Owning anti-drone systems with nanodrones

Speakers:

David Melendez Cano R&D Embedded Systems Engineer. Albalá Ingenieros S.A.

This talk provides a new vision about drone protection against anti-drone systems, presenting "The Interceptor Project", a hand-sized nano drone based on single-core tiniest Linux Board: Vocore2.

3. Your Watch can watch you ! Gear up for broken privilege pitfalls in...

Speakers:

  • Dongsung Kim, Graduate Student, Sungkyunkwan University
  • Hyoung-Kee Choi, Professor, Sungkyunkwan University

In this talk, we will investigate if the Samsung Gear smartwatch series properly screens unauthorized access to user information. More specifically, we will focus on a communication channel between applications and system services, and how each internal Tizen OS components play the parts in access control.

4. HACKING THE BRAIN: Customize Evil Protocol to Pwn an SDN Controller

Speakers: 

  • Feng Xiao, Hacker
  • Jianwei Huang, Hacker
  • Peng LiuRaymond G. Tronzo, M.D. Professor of Cybersecurity

In this talk, we extend the attack surface and introduce Custom Attack, a novel attack against SDN controllers that leverages legitimate SDN protocol messages (i.e., the custom protocol field) to facilitate Java code vulnerability exploitation. Our research shows that it was possible for a weak adversary to execute arbitrary command or manipulate data in the SDN controller without accessing the SDN controller or any applications, but only controlling a host or a switch.

5. It's Assembler, Jim, but not as we know it: (ab)using binaries from...

Speakers:

Morgan ``indrora'' Gangwere, Hacker

With the proliferation of Linux-based SoCs -- you've likely got one or two in your house, on your person or in your pocket -- it is often useful to look "under the hood" at what is running; Additionally, in-situ debugging may be unavailable due to read-only filesystems, memory is often limited, and other factors keep us from attacking a live device. This talk looks at attacking binaries outside their native environment using QEMU, the Quick Emulator, as well as techniques for extracting relevant content from devices and exploring them.

6. Jailbreaking the 3DS through 7 years of hardening

Speakers:

smea, Hacker

This talk will describe hacking the console through all these defensive features by walking through a 0-day exploit chain that takes us all the way from zero access to a full system jailbreak.

7. Breaking Smart Speakers: We are Listening to You.

Speakers:

  • Wu HuiYu, Security Researcher At Tencent Blade Team
  • Qian Wenxiang, Security Researcher At Tencent Blade Team

In this talk, we will present how to use multiple vulnerabilities to achieve remote attack some of the most popular smart speakers. Our final attack effects include silent listening, control speaker speaking content and other demonstrations. And we're also going to talk about how to extract firmware from BGA packages Flash chips such as EMMC, EMCP, NAND Flash, etc. In addition, it contains how to turn on debug interfaces and get root privileges by modifying firmware content and Re-soldering Flash chips, which can be of great help for subsequent vulnerability analysis and debugging. Finally, we will play several demo videos to demonstrate how we can remotely access some Smart Speaker Root permissions and use smart speakers for eavesdropping and playing voice.

8. Infecting the Embedded Supply Chain

Speakers: 

  • Zach, Security Researcher at Somerset Recon
  • Alex, Security Researcher at Somerset Recon

In this talk we discuss the various attack vectors that these embedded development tools expose users to, and why users should not blindly trust their tools. This talk will detail a variety reverse engineering, fuzzing, exploit development and protocol analysis techniques that we used to analyze and exploit the security of a common embedded debugger.

9. A Journey into Hexagon: Dissecting Qualcomm Basebands

Speakers:

Seamus Burke, Hacker

In this talk, we will dive into the internals of a qualcomm baseband, tracing it's evolution over the years until its current state. We will discuss the custom, in-house DSP architecture they now run on, and the proprietary RTOS running on it. We will also cover the architecture of the cellular stack, likely places vulnerabilities lie, and exploit mitigations in place. Finally we will cover debugging possibilities, and how to get started analyzing the baseband firmware—how to differentiate between RTOS and cellular functions, how to find C std library functions, and more.

10. What the Fax!?

Speakers:

  • Yaniv Balmas, Security Researcher, Check Point Software Technologies
  • Eyal Itkin, Security Researcher, Check Point Software Technologies

This talk is intended to be the canary in the coal mine. The technology community cannot sit idly by while this ongoing madness is allowed to continue. The world must stop using FAX!
