Computer malware in all its forms is nearly as old as the first PCs running commodity OSes, dating back at least 30 years. However, the number and the variety of "computing devices" dramatically increased during the last several years. Therefore, the

Writing a working exploit for a vulnerability is generally challenging, time-consuming, and labor-intensive. To address this issue, automated exploit generation techniques can be adopted. In practice, existing techniques however exhibit an insufficie

Deep learning can help automate the signal analysis process in power side channel analysis. So far, power side channel analysis relies on the combination of cryptanalytic science, and the art of signal processing. Deep learning is essentially a class

There has been much discussion of "software liability," and whether new laws are needed to encourage or require safer software. My presentation will discuss how -- regardless of whether new laws are passed -- a tidal wave of litigation over defective

In this talk, we will explore the baseband of a modern smartphone, discussing the design and the security countermeasures that are implemented. We will then move on and explain how to find memory corruption bugs and exploit them. As a case study, we

Although vulnerabilities stemming from the deserialization of untrusted data have been understood for many years, unsafe deserialization continues to be a vulnerability class that isn't going away. Attention on Java deserialization vulnerabilities sk

2018 started off with a bang as the world was introduced to a new class of hardware vulnerability which became known as Meltdown and Spectre. New classes of vulnerabilities are exceedingly rare and this one came with ramifications for the security bo

WebAssembly (WASM) is a new technology being developed by the major browser vendors through the W3C. A direct descendent of NaCl and Asm.js, the idea is to allow web developers to run native (e.g. C/C++) code in a web page at near-native performance.

Humans are susceptible to social engineering. Machines are susceptible to tampering. Machine learning is vulnerable to adversarial attacks. Researchers have been able to successfully attack deep learning models used to classify malware to completely

The term "smart city" evokes imagery of flying cars, shop windows that double as informational touchscreens, and other retro-futuristic fantasies of what the future may hold. Stepping away from the smart city fantasy, the reality is actually much mor

In this talk, we will unveil the new in-house capabilities of a nation state actor who has been observed deploying both Android and iOS surveillance tooling, known as Stealth Mango and Tangelo. The actor behind these offensive capabilities has succes

In this talk, we will unveil the new in-house capabilities of a nation state actor who has been observed deploying both Android and iOS surveillance tooling, known as Stealth Mango and Tangelo. The actor behind these offensive capabilities has succes

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:

OpenPGP and S/MIME are the two prime standards for providing end-to-end security for emails. From today's viewpoint this is surprising as both standards rely on outdated cryptographic primitives that were responsible for vulnerabilities in major cryp

Until recently, major public cloud providers have offered relatively basic toolsets for identifying suspicious activity occurring inside customer accounts that may indicate a compromise. Some organizations have invested significant resources to build

On macOS, DEP (Device Enrollment Program) and MDM (Mobile Device Management) are the recommended methods for automating the initial setup & configuration of new devices. MDM can offer sophisticated system configuration options, including privileged o

Every single security company is talking in some way or another about how they are applying machine learning. Companies go out of their way to make sure they mention machine learning and not statistics when they explain how they work. Recently, that'

Financial institutions, home automation products, and hi-tech offices have increasingly used voice fingerprinting as a method for authentication. Recent advances in machine learning have shown that text-to-speech systems can generate synthetic, high-

To keep up with the growing demand of always-on and available-anywhere connectivity, the use of cellular, in comparison to its wireless mobile connectivity counterpart in the electromagnetic spectrum, is rapidly expanding. My research in the IoT spac

Recent advancements in OS security from Microsoft such as PatchGuard, Driver Signature Enforcement, and SecureBoot have helped curtail once-widespread commodity kernel mode malware such as TDL4 and ZeroAccess. However, advanced attackers have found w
