Using OSINT for Human Rights and Victim Support

Rae Baker

Open-Source Intelligence can have both positive and negative impacts on vulnerable populations such as domestic violence and stalking victims. We will discuss the ways that OSINT has been used in the past to target victims and how it may evolve in the future. Then, pivoting from the negative, we take a look at how non-profit organizations are beginning to use OSINT for good. I will show some examples of OSINT models being used to help victims of crimes regain control of their situation and how OSINT professionals are using it to keep victims safe. Finally, we will look at ways that you, as a security professional, can use your skillset to promote change and have a greater understanding of the importance of privacy, empathy, and safety for victims.

Battling Supermutants in the Phishing Wasteland

Ashlee Benge and Zack Allen

Phishing attacks are nothing new or unusual, and yet the menace they pose is often overlooked in lieu of flashier malware, APTs, and 0-day exploits. This talk will discuss the state of modern phishing, delving into the economy of phishing. It will detail the roles within this economy and why it presents such a risk to organizations. Using RPG-style stat cards to highlight author strengths and weaknesses, we will then present our research on three phishing kit authors, break down their offerings, and discuss what it takes to run a successful phishing kit empire.

Hacking Democracy: On Securing an Election

Casey Ellis, Tod Beardsley, Kimber Dowsett, Jack Cable, and Amelie Koran (moderator)

Democracy is the cornerstone of America’s Constitution, identity, and ideology, and this foundation was shaken during the 2016 Presidential Election. Four years later, we still have great lengths to go to ensure that the integrity of the 2020 Presidential Election, and any election moving forward, is protected.

The Senate approved a $250 million budget to assist with election cybersecurity efforts across the country, but is it enough? The Presidential Race is on but so is the race to secure the 2020 vote.

In this panel we’ll discuss the intersection of people, technology, security, and elections, with a focus on themes including:

  • The true scope of the problem when it comes to “hacking elections”
  • The biggest threats to the 2020 vote–threat modeling for disinformation, voting machine vulnerabilities, website hacking, and election manipulation
  • The role of hackers and coordinated vulnerability disclosure in building voter trust and improve cyber-resilience
  • The impact for the elections in the west at large, driven by the U.S.’s prominence as the champion for democracy.

As founder and CTO of Bugcrowd, Casey Ellis (@caseyjohnellis) pioneered the crowdsourced-security-as-a-service model.

Tod Beardsley (@todb) directs the security research program at Rapid7.

Adventures in Hardware Hacking or Building Expensive Tools on a Budget

Zac Franken

CT Scanning is one of the gold standards for hardware hacking. It enables a user to slice and dice a 3D model of the device in question and most importantly it will allow a user to selectively slice through the model to extract key features such as the copper layers on multi-layer boards, embedded vias, embedded components, etc. It is these copper layers that represent the device’s circuit and therefore extracting them is a key method in enabling the reconstruction of the schematic from the physical device. This technique will allow non-destructive analysis of the device in question and will greatly shorten the phase of reversing the physical device to a logical schematic. I will also cover the construction of the Decapinator–an accurate non-destructive chip de-capping device that precisely exposes the silicon inside the epoxy chip package without damage to expose it for micro-probing, masked rom, and other detail extraction.

Zac Franken recently retired from 20 years as the Operations Director of DefCon. Zac’s research focuses on embedded systems security, access control systems, and biometric devices, and he has spoken and trained at information security conferences in Europe and the US publicly and for private and governmental audiences.

SBOM: Screw it, We’ll Do it Live!

Audie and Josh Corman

The concept of Software Bill of Materials (SBOM) isn’t that groundbreaking–we should know as much about the software that literally controls our lives as we do about the ingredients in a Twinkie. Yet changing the world can be hard. We set out not only to encourage others to be more transparent about their software supply chain but to show that it was possible and achievable, as well.

This talk will give an overview of the idea of SBOMs, their potential in the marketplace, and highlight how they can have a huge impact on the security of the critical healthcare sector. We’ll review why it’s needed, why there’s reluctance, and why it’s easier than you think. While the stories we share will be gleaned from the notoriously vulnerable healthcare sector, the lessons will be useful for anyone responsible for making, buying, or operating software and has ever wondered what was under the hood.

We need transparency across the entire software supply chain and for the first time, have a vision of what it can look like and some insight on how to get there. Now we need your help!

Privacy Scores for iOS Apps

Noelle Garrett

Privacy scores are a system for rating mobile apps on their use of private data. The source code behind the most popular mobile apps can often be difficult to gain access to. This means that the only information the user has on how their private data is handled by an application is through the vague privacy permissions users can grant. However, users don’t know what the app has been programmed to do with the data it has permissions to access, nor can users see what other information the app has access to without the user’s expressed approval. Using mitmproxy, the network traffic which Apple devices send out and receive can be intercepted and inspected, in order to see what data is being transmitted by different mobile apps. With the captured traffic, privacy scores are assigned to different applications based on four factors critical to measuring privacy.

However, privacy scores are not a complete solution for informing users about the private information their applications are using. The process for monitoring information flowing to/from iOS devices is already becoming thwarted by new techniques. It will only become more difficult for users to monitor the release of their private information as time advances.

Think of the Kitten: The Truth About Section 230, the Law All the Cute Online Cat Pictures (And a Lot of Other Good Stuff) Depends On

Cathy Gellis

It seems like everyone’s talking about Section 230 these days, and keen to change it, even without really knowing what it says and does. Don’t let this happen to you! Come to this crash course in Section 230 basics given by a lawyer who regularly litigates (and pontificates) about Section 230 to learn the truth about this crucial law that enables all our online cat pictures (and so much more). We’ll talk about why we have Section 230, what it does, why it works, and how badly we jeopardize our supply of online cat pictures (as well as a lot of other good, important stuff) if we mess with it.

Frustrated that people were making the law without asking her for her opinion, Cathy Gellis (@cathygellis) gave up a career as a web developer to become a lawyer so that she could help them not make it badly, especially where it came to technology.

Anti-Forensics for Fun and Privacy

Alissa Gilbert

Want to learn how to avoid surveillance and investigators? Anti-forensics is the practice of modifying or removing data so that others cannot find it later during an investigation. While annoying to forensic practitioners and law enforcement, it is unavoidable to help maintain privacy in a world of shady ToS, snooping partners, and potential search and seizures. How far do you need to go to maintain your privacy? This talk will break down anti-forensics techniques that you can use to protect yourself from audiences like your mom to an extreme nation-state level actor. The only thing more fun than forensics is anti-forensics.

Software Mitigations for Hardware Vulnerabilities

Antonio Gomez

In the last couple of years, we have observed the disclosure of a new set of innovative methods targeting internal structures and common hardware abstractions of many modern CPUs. These methods are relevant to many technology contexts, but what are these methods? Why are those hardware abstractions included in modern processors? What would the thread model of a potential implementation be? Even though these are methods that target the hardware, the existing mitigations for components that are already in the market, or that have even been out of the market for a while, are implemented in software. What do these software mitigations look like? What do they do? Do different actors understand these methods, what the mitigations do, and what they can do to configure these mitigations to better protect their systems based on their computing requirements? What can be done in the Linux kernel to enhance process isolation to prevent potential attacks? This presentation will answer all those questions while focusing on changes introduced in the Linux kernel and that are publicly available.

Knowing the UnFuzzed and Finding Bugs with Coverage Analysis

Mark Griffin

The rise in fuzzing has resulted in bugs getting found and fixed at an amazing rate. But it has raised some new questions: how do we find good fuzz targets quickly, and what is left to fuzz? These questions require tools and workflow that remain uncommon among software developers and security researchers alike, and one potential solution is in automated coverage analysis.

This motivation drove the development of bncov, an open-source coverage analysis plugin for Binary Ninja that enables scripting and the construction of tools to help you get the most bang for your fuzz-buck.

Mark Griffin is a researcher who has always been interested in working on difficult problems and always finding new ways to get the job done better. He’s been working in computer security for over 10 years, and in that time has realized he enjoys work more when he doesn’t have to use chopsticks to dig a ditch.

A Wireless Journeyman’s Experience in Practical SIGINT

Russell Handorf

This talk will be a demonstration of my experiences, joys, and frustrations in building a small home/office (SOHO) signals intelligence (SIGINT) platform. Starting as a custom system and solution called SoHoSIGINT, its design, architecture, and results will be briefly discussed but segways to a narrative and instruction about contributing to FOSS software. The result is the experience of contributing code to Kismet which enhanced the different kinds of wireless devices that are captured and logged in this platform. The finale is in the demonstration of creating new hardware to capture signals and integrating it into kismet. If I could do it, you can do it, and I’m going to show you how.

Dr. Russell Handorf (@dntlookbehindu) currently is a principal threat intelligence hacker for WhiteOps where he spends his time making criminals curse his very existence. He is also a recovering fed after ten years of service defending the country in a variety of matters. He’s done a lot of other odd things here and there, but that isn’t important.

5G Protocol Vulnerabilities and Exploits

Roger Piqueras Jover

The first protocol exploits against LTE were introduced in early 2016. Since then, security researchers have published a large number of excellent papers and talks identifying more and more critical vulnerabilities in the LTE protocol. 3GPP released the 5G specifications in 2018 and, by late 2019, a number of theoretical studies and formal verifications of the protocol have already identified several security issues. Despite a potential, yet optional, solution to prevent IMSI catching, 5G communication systems are still vulnerable to preauthentication message-based exploits. The 5G security architecture provides no means for mobile devices and base stations to verify cryptographically that they are not communicating with a malicious node until a substantial number of messages have been exchanged entirely in the clear. This talk will present the first security investigation of the 5G security specifications based on the analysis of real 5G traffic captures. Pre-authentication messages from real Release15-compliant 5G base stations, mobile devices and test tools, in both non-standalone (NSA) and standalone (SA) mode, will be analyzed. We will discuss ways in which an adversary could exploit these messages maliciously. The analysis will also demonstrate how certain exploits against LTE are still possible in 5G.

Voight-Kampff for Email Addresses: Quantifying Email Address Reputation to Identify Spear-Phishing and Fraud

Josh Kamdjou

“Is this email address real?” Internet history and age can’t be faked. Legitimate email addresses have social media profiles, Github profiles and commits, LinkedIn accounts, and they’ve been in credential dumps and data breaches. Real people can be differentiated from attacker personas using these internet breadcrumbs.

EmailRep is a system of crawlers, scanners, and enrichment services that collects data on email addresses, domains, and internet personas to predict the relative risk of an email address. It uses OSINT techniques, crawlers on forums, social media sites, and professional networking sites, as well as data points from credential breaches, malicious phishing kits, community reported phishing emails, spam lists, and more.

In this talk I’ll discuss why we built EmailRep, dive in to how Blue and Red teams are using this, and review some shortcomings of this approach that future attackers will seek to exploit. Finally, I’ll deep dive on the technical architecture and implementation, giving an overview of how you could build this yourself.

We’ll invite audience members on stage to query EmailRep, live, for their personal email addresses or attacker email addresses they’ve encountered or used in their work.

EmailRep is free to use via or API.

Whitelisting LD_PRELOAD for Fun and No Profit

Tony Lambert

Sometimes bolting a security solution on the side of technology just doesn’t work as well as built-in protection. One example of this on Linux systems is libpreloadvaccine, a whitelisting solution I built that aimed, and failed, to provide foolproof protection against abuse of LD_PRELOAD process injection. This talk will cover how adversaries use LD_PRELOAD, how its built-in audit system works, and how the audit system can be leveraged for whitelisting. We’ll also examine design and implementation considerations for whitelisting, closing the talk by showing how checks built into the dynamic linker would be much more effective than a solution thrown on top.

Tony Lambert (@ForensicITGuy) is a professional geek who loves to jump into all things related to detection and digital forensics.

Zoom 0-Day: How Not to Handle a Vulnerability Report

Jonathan Leitschuh

On July 8th, 2019, a bombshell 0-Day vulnerability was dropped on Zoom Inc. that disclosed how anyone could maliciously join a victim’s Mac to a call with their video camera active simply by visiting a malicious website. Additionally, Zoom left behind a hidden daemon that would re-install the Zoom client after it had been uninstalled. It was later discovered that this “feature” could be abused to allow remote code execution.

In this talk I’ll discuss my communications with Zoom’s security team and the reasoning behind what led to my decision to resort to 0-Day disclosure. Additionally, we’ll walk through the post-disclosure timeline around how this vulnerability went from bad to worse, requiring the Apple security team to step in and use MRT to resolve this vulnerability.

The Verilog to Verilog Decompiler

Katie Liszewski

Methods have been developed for conducting integrated circuit decomposition on fabricated chips to extract the as-fabricated design files such as the GDSII layout or gate-level netlist. While mature netlist equivalency checking tools are included with any design flow, there is a lack of tools for performing deeper analyses on the extracted designs for the purposes of hardware assurance or design recovery from obsolete parts. To this end, there is a need for a tool to extract functionality from netlists at a higher abstraction level to reconstruct behavioral Register Transfer Level (RTL) code.

Software decompilation is a well-established technique that has been used since the 1960s to recover lost source code, verify code against design changes produced by the compiler, and support detection of malicious code. In seeking to recover RTL, these 80 years of expertise in reconstructing functionality are invaluable. We introduce the terminology of “hardware decompilation” and explore where software techniques are relevant, how existing netlist structure recovery techniques fit into the decompilation pipeline, and present new techniques that are unique to hardware decompilation.

Katie Liszewski has a mathematics PhD and, since graduating, has specialized in solving computationally hard firmware and hardware security problems. At Battelle she leads efforts in emerging nondestructive counterfeit detection methods and process automation for hardware security. She has authored several papers in scalable second order effects based counterfeit detection.

Moose v. Woodchuck

Samantha Livingston

The world is buzzing with the claim that computers “can do X better than humans.” So then why did ShmooCon use animal picture identification to throw off bots during their most recent ticket sales? We’ll look at how computers are learning and more importantly how they are not learning… or alternatively how woodchucks are like moose. A simple framework will be introduced to help the you understand how a computer approaches problems. Then we’ll continue by examining potential computer security applications of machine learning to prepare you to evaluate its usefulness the next time you encounter a product that promises a “deep learning” or “AI” solution to all your problems. Throughout the discussion we’ll recognize the large datasets needed for machine learning algorithms to perform reliably and the resulting implications on privacy, whether it is your personal photos or your corporate intellectual property.

Samantha Livingston is a software developer in Boston, MA. Her interests include incorporating, exploiting, and promoting the use of exploratory data analysis tools in the design and development of robust software solutions for real-world problems.

Real World Zero Trust Implementation

Mark Loveless

A lot of vendors sell Zero Trust solutions. Or do they? Most are based upon their own product line that existed before Zero Trust became a thing and have simply been adapted, and none of them are complete solutions. I work at a company that is 100% cloud based, no perimeter or VPN, an open-source BYOD background, with a 100% remote employee base. We use dozens of SaaS solutions as a company; we have hundreds of servers/containers/images, multiple cloud providers for our services; and we are growing exponentially.

We wanted to deploy Zero Trust solutions as there are many benefits from a security standpoint of doing so, but after looking at the landscape out there, we had to get extremely creative in how we deployed any solution. Our solutions are not for you–they are for us–but we learned a lot getting to the point we are at now. I’ll describe what has happened so far, what we plan to do next, what has worked and what has not, and cover some important lessons that we think might be beneficial to all those considering Zero Trust, or simply shoring up security in general since that is essentially what most of Zero Trust boils down to.

Extracting an ELF From an ESP32

Chris Lyne and Nick Miles

The Espressif ESP32 is a system on a chip (SoC) “engineered for mobile devices, wearable electronics, and IoT applications.” It provides Wi-Fi and Bluetooth LE which makes it great for products needing wireless capabilities. While researching a consumer product, we discovered an ESP32 being used to provide Wi-Fi connectivity to the device. We found that there was limited tooling available to facilitate the reverse engineering process of an ESP32 firmware image. So, we decided to create tooling of our own.

We will talk about how we went about creating our tooling to extract an ELF file from an ESP32 flash dump. With excruciating amounts of detail, we will discuss the binary format of ESP32 firmware images as well as the process of converting it to an ELF file. By the end of the talk, you will know how to go from flash dump all the way to control flow graph in IDA.

Nick Miles (@_NickMiles_) joined Tenable as a Research Manager in 2011. He has written hundreds of Nessus plugins and developed several core libraries used in the Nessus engine.

Command and KubeCTL: Real-World Kubernetes Security for Pentesters

Mark Manning

Kubernetes is a security challenge that many organizations need to take on, and we as pentesters, developers, security practitioners, and the technically curious need to adapt to these challenges. In this talk we will look at tactics, techniques, and tools to assess and exploit Kubernetes clusters. We will demonstrate how to intercept service mesh traffic, evade runtime syscall filters, exploit custom sidecars, and chain attacks that go from compromising a build environment, to exploiting production applications. We’ll cover real world attack paths, provide practical advice, and guidance using the experience of conducting hundreds of reviews of containerized environments while running NCC Group’s container research group.

Mark Manning (@antitree) is a Technical Director with NCC Group and heads the container research practice there. He has been focused on containerization and orchestration technologies like Kubernetes and performs many of NCC Group’s containerization related assessments and research. This includes running container breakouts and attack simulations on orchestration environments, performing architecture reviews of devops pipelines, and working with developers to assist with applications that leverage containerization technologies like namespace isolation, Linux kernel controls, syscall filtering, and integration with products like Docker and Kubernetes.

Teen Hacks for Obfuscating Identity on Social Media

Russell Mosley and Samantha Mosely

It turns out our kids were listening to our caution about privacy, social media, and opsec. There is widespread use by teens “sharing” social media accounts with friends, i.e., having friends post to shared accounts: multiple phones, multiple locations (even globally) to confuse social media applications and obfuscate their identity. They figured out how to share accounts without sharing passwords and methods for monitoring accounts and deleting abusers in the group. They use different accounts for interacting with different groups, like that one they share with “old people.”

Father-daughter presenters, Russell and Samantha, will discuss the pro’s and con’s of these methods and share insights on what teenagers have learned from parents and from each other about privacy and opsec.

Resistance Isn’t Futile: A Practical Approach to Prioritizing Defenses with Threat Modeling

Katie Nickels

There are hundreds (if not thousands) of adversary groups out there, and it’s understandable if defenders sometimes feel like resistance is futile. Good news: you don’t have to defend against all of them! Even better news: there’s a simple way you can prioritize what adversaries you focus on and how you defend against them–threat modeling. This presentation will present a simple, practical threat modeling approach that any analyst or defender can use to get started figuring out what threats matter to their organization.

The presentation will start by acknowledging the many approaches to threat modeling that others have created, and then discuss why there’s confusion around it. The presentation will then explain four simple steps and practical actions that anyone can take to get started with threat modeling: know your organization, know your adversaries, match those up, and take action. The audience will leave with an understanding of how threat modeling can help any team prioritize what threats they care about and use that to improve their organization’s defenses.

Adversary Detection Pipelines: Finally Making Your Threat Intel Useful

Xena Olsen

Security teams often feel like they’re in a losing battle with threat intel. They don’t know how to make threat intel useful or operationalize it within their organizations, especially if there isn’t a dedicated full-time team. In this talk, we’ll help you extract more value out of your threat intel program, giving you an easy win to level up not just your team, but the other teams in your security department. First, we’ll explore why true attribution is so hard, from false flag operations and proxy attackers to obtaining all the forensic data you would need and even possible coordination with law enforcement or government agencies to perform true attribution. We’ll discuss TTPs and how they’re a lower-cost way of tracking threat activity groups for most organizations. Then we’ll introduce Adversary Detection Pipelines, how they can add value through prioritizing defensive and offensive activities as well as a discussion on the practical implementation of them in any organization. Finally, we’ll conclude by looking at case studies of how purple teams can leverage Adversary Detection Pipelines to enhance their operations and encourage an intelligence driven security program.

Crossing the Border With Your Electronic Devices

Kurt Opsahl and Bill Budington

Our lives are on our laptops: family photos, medical documents, banking information, details about what websites we visit, and so much more. Digital searches at national borders can reach our personal correspondence, health information, and financial records, allowing an affront to privacy and dignity which is inconsistent with the values of a free society. While privacy and security is important for any traveler, this has become a critical issue for security researchers, who often travel with confidential information, and who shouldn’t need to trade off an invasive search for participating in important conversations. This talk will discuss the both the legal and policy issues with border searches, as well as technological measures people can use in an effort to protect their data.

Chip Decapping on a Budget

Zach Pahle

What wondrous secrets lie beneath the surface of the integrated circuits that we use every day? The IC manufacturers don’t want you to know. However with some creativity and a tight budget, we can circumvent the obfuscation techniques employed by 99% of the IC industry and reveal a colorful cacophony of circuits, bond wires, and silicon dioxide. Now with more DIY!

Robots and Privacy

Brittany Postnikoff

Once data is taken in by a robot, it can be hard to tell where it will end up. One way to figure out how the data collected by robots will be treated and used is to read the privacy policies that come with the robots. Sometimes robot privacy policies can include clauses you likely wouldn’t expect. This presentation discusses the who, what, where, when, and why of robot data collection and the use of that data.

Project Everest: Fast, Correct, and Secure Software for Deployment Now!

Jonathan Protzenko and Nikhil Swamy

Project Everest is a joint research effort between Microsoft Research, INRIA, Carnegie Mellon, and the University of Edinburgh. Our goal is to provide high-performance standards-based secure communication components (e.g., TLS and QUIC) backed by mathematical proofs of their correctness and security. Additionally, we aim to show that software with formal proofs can be developed and deployed at scale today, within the existing software ecosystem.

Our code is programmed in F*, a language designed for co-developing programs and proofs. We prove our code memory safe (no buffer overflows, no use-after-free, etc.); functional correct (we always compute the right result); side-channel resistant (ruling out cache and timing-based leaks); as well as provide several application-specific guarantees.

Our programming tools and verified components are open source on GitHub, including the following highlighted components:

  • EverCrypt, a functionally correct and side-channel resistant cryptographic library that matches or exceeds the performance of any other library for many algorithms
  • EverParse, a library of verified parsers and formatters for binary formats
  • EverQuic-transport, an implementation of the QUIC transport layer proven cryptographically secure

Our code is distributed as a set of C files, for easy integration with existing code. Several large projects have already adopted our components, including Firefox, Windows, Wireguard, mbedTLS, the Tezos blockchain, and many others: you should too!

Jonathan Protzenko, PhD, (@_protz_) is a Senior Researcher at Microsoft Research in Redmond. His interests revolve around type systems, language design, and software verification. Jonathan drives the EverCrypt project and wrote the F*-to-C compiler used pervasively throughout Project Everest.

Nikhil Swamy, PhD, is a Principal Researcher at Microsoft Research in Redmond, working broadly in the area of programming languages and computer security. He leads the design and implementation of the F* programming language and co-leads Project Everest.

Banjo: An Android Disassembler for Binary Ninja

Austin Ralls

A common recommendation for reverse engineering Android apps is to start with a decompiler to Java (like JADX or JD-GUI) and look at Smali generated by baksmali for methods where they fail. In an obfuscated or just weird application, many methods can fail decompilation, forcing us back into the dark ages of reading text disassembly.

This presentation will release Banjo, a plugin for Binary Ninja that brings interactive disassembly features like references, graph mode, and a Python 3 API to Smali. Banjo also includes a standalone Smali disassembler that attempts to produce the same output format as baksmali. The presentation will also cover how to make Binary Ninja do things it wasn’t designed to do while disassembling a complex VM language. This includes details of why Android apps in particular posed a challenge, what workarounds were employed, and some undocumented features of Binary Ninja that can help you write your own plugins for other languages.

What if We Had TLS for Phone Numbers? An Introduction to SHAKEN/STIR

Kelley Robinson

If you’ve noticed a surge in unwanted robocalls from your own area code in the last few years, you’re not alone. The way telephony systems are set up today, anyone can spoof a call or a text from any number. With an estimated 85 billion spam calls globally, it’s time to address the problem.

This talk will discuss the latest advancements with STIR (Secure Telephone Identity Revisited) and SHAKEN (Signature-based Handling of Asserted information using toKENs), new tech standards that use well accepted public key cryptography methods to validate caller identification. We’ll discuss the path and challenges to getting this implemented industry wide, where this tech will fall short, and what we can do to limit exposure to call spam and fraud in the meantime.

Kelley Robinson (@kelleyrobinson) works on the Account Security team at Twilio, helping developers manage and secure customer identity in their software applications.

Playing the Short Game: The Effects of Data Breaches on Share Prices

Chaim Sanders

The security industry is quick to point out that data breaches will negatively affect the public perception of an organization. While regulatory fines and lawsuits may also impose financial penalties, they often only represent a slap on the wrist compared to the cost of maintaining an effective security program. With over two hundred breaches disclosed against public companies in the last thirteen years, I investigate if the security shortfalls of breached organizations can impact their stock price. In this session I examine and expand upon existing work identifying the effects of announced breaches on publicly traded companies. Using this expanded dataset I will determine what measurable fiduciary effects breach notifications have on public companies and possible future trends in this area.

Choose Your Own Adventure: Ransomware Response!

Heather Smith

This talk starts out simple enough–the CISO has contacted you, the incident responder. There’s a ransom note, they’re yanking and rebooting machines, mass panic, now what?

Walk through a full ransomware scenario, stopping along the way to vote on crucial turning points as an audience. What flavor of malware will you find? Will there be more than one threat actor? APT or script kiddie? Oh no, is that Joe from accounting’s nudes?

This talk is based on multiple REAL ransomware cases, they’ve just been obfuscated to protect the innocent. Come for the memes, catharsis, and bizarre stories that can result–you choose!

Reverse Engineering Apple’s BLE Continuity Protocol for Tracking, OS Fingerprinting, and Behavioral Profiling

Sam Teplov

We reverse engineer several message types of Apple’s Bluetooth Low Energy (BLE) Continuity protocol, and show that they can be used for tracking, operating system fingerprinting, and behaviorally profiling users. In particular, we identify and reverse engineer seven distinct message types, most of which are sent in response to a particular user interaction with their iOS or macOS device. Through a series of rigorous tests in a radio-frequency sterile environment, we i) determine what actions are necessary to stimulate a device to transmit these messages, ii) deduce the meanings of most fields within each message type, and iii) ascertain how operating system version updates have introduced and affected each message type. Together, this information allows an adversary within BLE transmission range to determine what actions a user is making on their device, infer what operating system version they are using, and even track users despite the use of randomized BD_ADDR. Finally, we introduce, demonstrate, and publicly release the first-ever Wireshark dissector for displaying the Continuity message types we and other security researchers have reverse engineered.

The FuriousMAC research group at the US Naval Academy was established in 2015 to investigate computer security and privacy topics. The group consists of current and former cyber operations and computer science faculty, as well as undergraduate and recently-graduated student researchers.

Security Researcher OPSEC

Krassimir Tzvetanov

Whether performing an in-depth investigation or merely quick research, the investigator (or researcher) and the investigation itself are exposed to certain risks.

This talk focuses on security and safety issues pertaining to online research and investigations. It covers different areas of the investigative process and how tools and particular techniques can leak information detrimental to the case or the investigator.

Furthermore, it goes deeper into how investigators and blue teams can be profiled and targeted. Those can be either direct attack against their computer or supporting infrastructure, their person, or the investigation, which in turn may be as subtle as steering it in the wrong direction or making the evidence inadmissible in court.

More specifically the talk will cover different browser and infrastructure fingerprinting techniques, browser hooking, instant messaging programs, email security, and tracking.

As it covers the dangers, this talk provides series of countermeasures and mitigations, which can help the investigator increase their level of safety and security and decrease their digital footprint.

In addition, the talk introduces containerization and how it can be used to segment and streamline the process.

Krassimir Tzvetanov is a graduate student at Purdue University focusing on Threat Intelligence, Operational Security, and Counterintelligence techniques (in the cyber domain). In the recent past, Krassimir was a security engineer at a small CDN, where he focused on incident response, investigations, and threat research.

Face/Off: Action Plan for Perils & Privileges of Facial Recognition

Elizabeth Wharton and Suchi Pahi

Biometric data points, facial recognition, is becoming ubiquitous–unlocking your phone, airline boarding passes, law enforcement, in-store marketing metrics, even ordering fast food. As engineers, managers, or leaders–focus is on revenue, design, and cutting-edge technology. But what about the other effects of facial recognition? Your voice may be your password, but what happens when it’s your face and there’s a data breach or the data is wrong. With studies indicating error ranges in excess of 35%, increasing state biometric related privacy statutes, and biometric data breaches on the rise–what should you be worried about and watching as an architect and designer of such systems?

We’re going to discuss the current facial recognition use cases, growing regulatory concerns, the consequences of facial recognition, and what you can do to make sure that facial recognition technology doesn’t run amok.

Hack the Stars

Yacko, Wacko, and Dot

The year is 2020, and NASA struggles to deliver public-sector access to space while megacorporations are planning the colonization of Mars. “Hack the Planet” was thinking too small. As commercial enterprise expands in to space faster than regulatory bodies can adapt, the security and technology posture of space-based systems looks a lot like the wild west of the party line days of phone phreaking. On the ground more and more groups rely on satellite data links to connect critical infrastructure and deliver cat videos to isolated personnel, and in the air numerous non-government organizations are deploying remote sensing cubesats to orbit for science and profit. As the cost of RF equipment to engage these systems goes down, the likelihood that casual hackers will go after your space asset naturally goes up. This talk will examine the attack surface presented by space-based communications relays and sensing platforms. We will share our experience and some tips on how to build simple solutions to get started hacking the stars, then outline a few theoretical methods to defensively instrument the astroenterprise.

Yacko, Wacko, and Dot started their infosec careers after their hit TV show went off the air in 1998.
