We're living in yesterday's future, and it's nothing like the speculations of our authors and film/TV producers. As a working science fiction novelist, I take a professional interest in how we get predictions about the future wrong, and why, so that I can avoid repeating the same mistakes. Science fiction is written by people embedded within a society with expectations and political assumptions that bias us towards looking at the shiny surface of new technologies rather than asking how human ...

Formal hardware verification (hardware model checking) can prove that a design has a specified property.

The Snowden Refugees’ actions to protect the world’s most significant whistle blower of the 21st Century, amounts to an expression of Political Opinion. Since September 2016, the Snowden Refugees have been systematically targeted and persecuted by the Hong Kong government based on that political opinion.

While technology is often described as an extension of our bodies, this talk will explore a reversed relationship: Bodies and minds of digital laborers (you and me and basically everybody else) as software extensions that can be easily plugged in, rewired, and discarded. I will approach this topic from an artist's point of view.

Faced with new responsibilities to prevent terrorism and money laundering, banks have built a huge surveillance infrastructure sweeping up millions of innocent people. Investigative journalists Jasmin Klofta and Tom Wills explain how, as part of an international collaboration, they exposed World-Check, the privately-run watchlist at the heart of the system.

In this talk we will present a deep-dive analysis of the anatomy of QNX: a proprietary, real-time operating system aimed at the embedded market used in many sensitive and critical systems, particularly within the automotive industry. We will present the first reverse-engineering and analysis of the exploit mitigations, secure random number generators and memory management internals of QNX versions up to and including 6.6 and the brand new 64-bit QNX 7.0 (released in March 2017) and uncover a ...

Many claims were made recently about purpose and capabilities of the Intel ME but with all the buzz it is not always clear what are facts and what is just speculation. We'll try to clear the fog of misunderstanding with research based on investigations of ME firmware and practical experiments on ME-equipped hardware.

The <a href="https://noiseprotocol.org">Noise Protocol Framework</a> is a toolkit for 2-party secure-channel protocols. Noise is used by WhatsApp for client-server communication, by the WireGuard VPN protocol, and by the Lightning Network. In this talk I'll describe the rationale behind such a framework, and how you can use it to build simple, efficient, and customized secure-channel protocols.

This talk will go over our efforts to implement a new open source DBI framework based on LLVM. We'll explain what DBI is used for, how it works, the implementation challenges we faced and compare a few of the existing frameworks with our own implementation.

Address Space Layout Randomization (ASLR) is fundamentally broken on modern hardware due to a side-channel attack on the Memory management unit, allowing memory addresses to be leaked from JavaScript. This talk will show how.

Systems that hide their firmware-- often deep in readout-protected flash or hidden in encrypted ROM chips-- have long stymied reverse engineers, who often have to resort to inventive methods to understand closed systems. To help reduce the effort needed to get a foothold into a new system, we present GlitchKit-- an open source hardware and firmware solution that significantly simplifies the process of fault-injecting your way into a new system -- and of fault-injecting firmware secrets out! This ...

Hacker culture overcomes limitations in computer systems through creativity and tinkering. At the same time, hacker culture has shaped the practice of software development to this day. This is problematic - techniques effective for breaking (into) a computer systems are not necessarily suitable for developing resilient and secure systems. It does not have to be this way: We can approach software development as a methodical, systematic activity rather than tinkering, and teach it accordingly. ...
