Alan Sguigna

Although he does have a day job, Alan Sguigna has been moonlighting for 10+ years doing JTAG debug of UEFI targets. Having tired of that, he convinced a bunch of developers to enhance their existing UEFI tools to debug the Windows kernel as well, including Hyper-V and VBS-enabled targets.
Author of The MinnowBoard Chronicles and a prolific blogger on technical topics, Alan enjoys simplifying complex topics, and making knowledge accessible to all.

Alessandro Di Federico

One day while playing a CTF I thought "hey, this decompiler could be done better".

I like C++, LLVM, binaries, Free Software and privacy.

During my dark academia years I presented at USENIX, DEF CON and several other compilers/computer security conferences.

I'm the co-founder of Labs, the company developing the decompiler.
My activities include overseeing the overall design and maintaining the first half of the decompilation pipeline.

Andrea Allievi

Andrea Allievi is a system-level developer and security research engineer with more than 18 years of experience. He graduated from the University of Milano-Bicocca in 2010 with a bachelor’s degree in computer science. For his thesis, he developed a Master Boot Record (MBR) Bootkit entirely in 64-bits, capable of defeating all the Windows 7 kernel-protections (PatchGuard and Driver Signing enforcement). Andrea is also a reverse engineer who specializes in operating systems internals, from kernel-level code all the way to user-mode code. He was the original designer of the first UEFI Bootkit (developed for research purposes and published in 2012), multiple PatchGuard bypasses, and many other research papers and articles. He is the author of multiple system tools and software used for removing malware and advanced persistent threads. In his career, he has worked in various computer security companies—Italian TgSoft, Saferbytes (now MalwareBytes), and Talos group of Cisco Systems Inc. He originally joined Microsoft in 2016 as a Security Research Engineer in the Microsoft Threat Intelligence Center (MSTIC) group. Since January 2018, Andrea has been a Principal Core OS engineer in the Kernel Security Core team of Microsoft, where he mainly maintains and develops new features (like Retpoline, Speculation Mitigations, Function Overrides, ARM64 Import Optimization, Trusted Apps and many more...) for the NT and Secure Kernel. He is one of the main author of the Windows Internals book.

Andrea continues to be active in the security research community, authoring technical articles on new kernel features of Windows in the Microsoft Windows Internals blog, and speaking at multiple technical conferences, such as Recon and Microsoft BlueHat.

Cristina Cifuentes

As Vice President of Oracle's Software Assurance organisation, I lead a team of world-class security researchers and engineers whose passion lies in solving the big issues in Software Assurance. Our mission is to make application security and software assurance, at scale, a reality. We enjoy working with today's complex enterprise systems composed of millions of lines of code, variety of languages, established and new technologies, to detect vulnerabilities and attack vectors before others do. Automation is important, so are security assessments.

Cristina was the founding Director of Oracle Labs Australia in 2010, a team she led for close to 12 years. As Director of Oracle Labs Australia, I led a team of world-class Researchers and Engineers whose passion lies in solving the big issues in Program Analysis. Our team specialises in software vulnerability detection and developer productivity enhancement – in the context of real-world, commercial applications that contain millions of lines of code. My team successfully released Oracle Parfait, a static analysis tool used by thousands of C/C++/Java developers each day. Our inventions have resulted in dozens of US patents at Oracle and Sun Microsystems, and our impact on program analysis is well known through our active participation and publication record.

Cristina’s passion for tackling the big issues in the field of Program Analysis began with her doctoral work in binary decompilation at the Queensland University of Technology, which led to her being named the Mother of Decompilation for her contributions to this domain. In an interview with Richard Morris for Geek of the Week, Cristina talks about Parfait, Walkabout and her career journey in this field.

Before she joined Oracle and Sun Microsystems, Cristina held academic posts at major Australian Universities, co-edited Going Digital, a landmark book on Cybersecurity, and served on the executive committees of ACM SIGPLAN and IEEE Reverse Engineering.

Cristina continues to play an active role in the international programming language and software security communities. Where possible, she channels her interests into mentoring young programmers through the CoderDojo network and mentoring women in STEM.

The mission of the Open Organisation Of Lockpickers is to advance the general public knowledge about locks and lockpicking. By examining locks, safes, and other such hardware and by publicly discussing our findings we hope to strip away the mystery with which so many of these products are imbued.

The more that people know about lock technology, the better they are capable of understanding how and where certain weaknesses are present. This makes them well-equipped to participate in sportpicking endeavors and also helps them simply be better consumers in the marketplace, making decisions based on sound fact and research.

The Open Organisation Of Lockpickers, or TOOOL, is an international group of lockpicking enthusiasts dedicated to advancing the general public knowledge about locks and lockpicking through teaching, research, and competition. TOOOL in the United States is a 501(c)(3) non-profit organization with Chapters in the United States and Canada.
