Privacy on the blockchain: insights from 3 leading projects
Projects like Enigma and Keep are developing solutions to keep sensitive data private but useful on the blockchain. Doing so would be a leap forward for dApps and a provide a stronger bridge to enterprise users. What are the key problems and which of these solutions is likely to succeed? Ana De Sousa is a consultant and analyst focused on commercial applications of blockchain technology. Previously, she led analytics teams at LinkedIn and AT Kearney. She’s delighted to finally put her BA in Economics to use.
Containers aka crazy user space fun
Like the movie Plan 9 from outer space, this talk will cover containers from user space. What are they? Where did they come from? How much koolaid is involved in adopting them into your life… Come for the jokes, stay for the interesting technical details. Jess Frazelle works at Microsoft on open source, containers, and Linux. She has been a maintainer of Docker, contributor to RunC, Kubernetes and Golang as well as other projects. She loves all things involving Linux namespaces and cgroups and is probably most well known for running desktop applications in containers and her work on making containers secure.

Mark Mossberg of Trail of Bits gave a short demo of Manticore, a ruthlessly effective hybrid symbolic-concrete (“concolic”) execution system that scales to large programs with numerous dependencies, complex interaction, and manual setup. Manticore is being prepared for a public release in March.
Bootstrapping a slightly more secure laptop
Heads is an open source custom firmware and OS configuration for laptops and servers that aims to provide slightly better physical security and protection for data on the system. Unlike Tails, which aims to be a stateless OS that leaves no trace on the computer of its presence, Heads is intended to store data and state. It targets specific models of commodity hardware and takes advantage of lessons learned from vulnerability research. This talk provides an overview of Heads, a demo of installing it on a Thinkpad, and a tour of the attacks that it protects against. Presented by Trammell Hudson.
When Bad Things Happen to Good Computers
We discuss the current state-of-the-art in the field of electromagnetic fault injection (EMFI) and our on-going research into the matter. We present motivational examples show-casing the potential capabilities of EMFI techniques against secure embedded hardware. We also discuss the draw-backs of traditional EMFI techniques and hard physical limitations of such techniques in its current incarnation. Lastly, we informally unveil our soon-to-be-open-sourced BadFET, a high-powered nano-second zero-recovery time multiple firing EMP system, and yes, it will probably kill you if you touched it. Presented by Ang Cui and Rick Housley of Red Balloon Security.
Be a Binary Rockstar: An Intro to Program Analysis with Binary Ninja
Many static analyses, such as LLVM passes, depend on the ability to compile source code and cannot operate on binaries. Binary Ninja offers a new Intermediate Language (IL) that makes running such analyses on binaries much easier. I will describe how to use the Binary Ninja IL to automatically discover memory corruption vulnerabilities in binary code, and introduce the concepts of variable analysis, abstract interpretation, and integer range analysis in the process. Presented by Sophia D’Antoine of Trail of Bits.
Shuffler: Fast and Deployable Continuous Code Re-Randomization
Just-In-Time ROP (JIT-ROP) techniques, where an attacker uses a memory disclosure vulnerability to discover code gadgets at runtime are particularly pernicious. We designed a code-reuse defense, called Shuffler, which continuously re-randomizes code locations on the order of milliseconds, introducing a real-time deadline on the attacker. Shuffler focuses on being fast, self-hosting, and nonintrusive to the end user. Evaluation shows that Shuffler defends against all known forms of code reuse, including ROP, direct JIT-ROP, indirect JIT-ROP, and Blind ROP. Presented by David Williams-King, a PhD student at Columbia University.
Differential Fuzzing with LLVM’s LibFuzzer
We extended libFuzzer to support differential fuzzing of applications of similar functionality (e.g., SSL libraries) and developed a set of new metrics to guide input generation, particularly retrofitted towards differential testing. We’ll be doing a demo of the engine and present some of the bugs we found. Presented by Theofilos Petsios and Adrian Tang, PhD candidates at Columbia University.
Firing Rounds at the Analysis Shooting Gallery
DARPA spent hundreds of thousands of my tax dollars creating small C and C++ programs that include exploitable software flaws. We took those programs, ported them to Linux and OS X, and used them as a shooting gallery for static and dynamic analysis tools. Let’s see where each tool excels and where each tool fails. Presented by Ryan Stortz, a principal security researcher at Trail of Bits.
Lots of new faces at our meeting last week with almost 100 total attendees. Here's some feedback we received: pic.twitter.com/jBtv9e3wzA— Empire Hacking (@EmpireHacking) October 17, 2016
ProtoFuzz: A Google Protocol Buffers Message Generator
Yan Ivnitskiy, a Principal Security Engineer at Trail of Bits, presented ProtoFuzz, a generic fuzzer for Google’s Protocol Buffers format. Instead of defining a new fuzzer generator for custom binary formats, protofuzz automatically creates a fuzzer based on the same format definition that programs use. ProtoFuzz is implemented as a stand-alone Python3 program.
Dash: A Web-based tool for Writing Shellcode
Pete Markowsky, a security researcher from NYC, presented Dash, a simple Python Flask-based web application for reading and writing assembly. Think of it as a REPL for various assembly languages. Dash explores how one might design an IDE for writing shellcode.
Algo: A 1-click IPSEC VPN in the Cloud
Dan Guido, CEO of Trail of Bits, presented Algo VPN, a set of Ansible scripts that simplifies the setup of an IPSEC VPN. It contains the most secure defaults available, works with common cloud providers, and does not require client software on most devices.

Doorman: An OSQuery Fleet Manager
OSQuery turns operating system information into a format that can be queried using standard SQL-based statements. But once you’ve got that data, how do you search it? Until now, you’d have to engineer your own front-end management console. Enter Doorman. This simple web interface allows you to manage your entire fleet of OSQuery machines. In this Empire Hacking talk, Marcin Wielgoszewski, a security engineer, demonstrated how Doorman works, and answered questions about its deployment and use.
Tidas: Passwordless Auth with the Secure Enclave
Nick Esposito, a Senior Software Engineer at Trail of Bits, discussed the design of Tidas, a solution for password-free authentication for iOS software developers. Tidas takes advantage of our unique capability to generate and store ECC keys inside the Secure Enclave.
Beyond Corp: Lessons learned from 5 years of endpoint attestation
An increasingly mobile workforce and the ubiquity of attacks on client platforms limit the effectiveness of the traditional corporate network perimeter-security model. Beyond Corp is a broad effort to re-architect the delivery of Google corporate computing services, removing privileges granted solely on the basis of network address. The underlying architecture relies on a model of machine identity, authentication, and state-aware authorization to provide differential to services. August Huber, a data defender at Google, discussed the background of the work, general approach, challenges encountered, and future directions.
We just broke our pre-registration record (75 hackers)! Come see BeyondCorp, Tidas, and Doorman tomorrow @Spotify https://t.co/tlBDTOu5md— Empire Hacking (@EmpireHacking) June 6, 2016
