When Penetration Testing Isn’t Penetration Testing At All Virtual Ted Harrington
Abstract

When companies want to build secure IoT systems, they know they need to test their system for security flaws, which typically leads them to seek out “penetration testing.” However, this term has become so misused across the security community that it’s hard to decipher what is really happening.
So where does that leave you? What is your security testing program actually doing (and not doing)?
In this keynote, you’ll learn the often widely misunderstood difference about what penetration testing is (and is not). Drawing insights from the #1 bestselling book Hackable, you’ll learn why the distinction matters, and you’ll get an insight into the more advanced tactics used by ethical hackers, such as functionality abuse and exploit chaining. By design, this keynote is more strategic rather than technical, and will equip you with insights to think differently about your security testing program. As a result, you’ll leave with new ideas about how to build better, more secure systems.

Representation Matters Virtual Chloe Messdaghi and Camille Eddy
Abstract

We often hear about the importance of Diversity, Equity, and Inclusion (DEI) and how companies are striving to do better. However, there are plenty of examples where DEI that is being promoted is not actually happening behind scenes. Stories of those who are marginalized in tech showcasing we still have a large problem with companies practicing lip service and no actual actions to show for it. One way to see if a company is trying to be better on DEI is reflected on the board and C-suite. Yet, still to this day less than 20% of company boards represent marginalized identities.
It's time to increase representation of marginalized identities from less than 20% to 50%+ for all levels in tech. When we shift to incorporating DEI practices by making sure representation is present on the leadership team, board and c-suite, it recognizes the voices of marginalized identities: ethnicities, genders, generations, sexuality, and abilities.
Research has repeatedly shown that when we have diverse boards and c-level positions held by marginalized persons, it produces a trickle down effect. Where the company takes actions and voices are finally heard because there’s representation, and it's reflected in the vision, company policies, and hiring practices.
This talk discusses why we need representation on the leadership team, and how to get involved to actually bring a change to an industry that has run out of time to become more inclusive.

1.21 Gigawatts! Vulnerabilities in Solar Panel Controllers Onsite Waylon Grange
Abstract

Embedded device security has come a long way since the days of telnet and default passwords. Product vendors are now doing more to secure their devices but how effective are they? This presentation will outline many of the software and hardware-based attacks used to compromise embedded systems. It also discusses some of the mitigations used to prevent these attacks. Many previous IoT talks show the simplicity of hacking devices that have weak security or no hardening. In contrast, this presentation shows how even secured devices have attack surfaces that still need to be addressed. It demonstrates the need for embedded devices to incorporate a security lifecycle plan and hardware designs must be audited for security weakness before production. Topics to be covered include firmware image encryption, disabling UART console access, hardening JTAG development access, securing e.MMC storage, NOR Flash protection, processor glitching, update lifecycle attacks, avoiding custom crypto, dealing with reverse engineers, and initial device setup vs authentication. None of these topics will be a deep dive. The intent is to show how they are attacked or utilized to mitigate specific attacks. To illustrate these topics the presentation will use a recent security audit of a US solar equipment manufacturer as a case study. The vendor incorporated many best practices for securing embedded devices but made some architecture decisions in the guise of security that ended up weakening their security posture rather than helping it. Finally, we'll show the ramifications of an attack against solar systems and how it could be used for racketeering. Attacks in this talk are beneficial to system designers, hobbyists, and researchers.

BLUEMONDAY Series – Exploitation & Mapping of vulnerable devices at scale through self-registration services (DATTO/ EGNYTE/ SYNOLOGY/ MERAKI/ GEOVISION) Onsite Ken Pyle
Abstract

Vendors like DATTO, MERAKI, GEOVISION, SYNOLOGY, EGNYTE and others are which leverage or depend on these services are imperiling data, networks, and businesses through insecure design, intentional design decisions, and web application flaws.

These devices frequently self-provision services which leak critical data or through insecure network design and installation practices which are easily mapped, attacked, and discovered via insecure vendor, software, and integrator practices (ex. PKI, Dynamic DNS, “Finder” service registrations, DNS leakage, Layer 2 Attacks / DHCP network attacks, DNS passive hijacking through domain purchases & active record injection)

Some concepts and new attacks may be obliquely referenced or held private by the researcher. Essential PoC is contained in this document and is easily reproduced using supplied narrative and screenshots.

The affected devices are easily discoverable either through insecure practices (ex. insecure Zones, algorithmic FQDN generation, lack of local network controls, public metadata leakage) or vendor provided interfaces and access methods. (DATTOWEB, DATTOLOCAL, SYNOLOGY.ME, DYNAMIC-M, GVDIP.COM, EGNYTE-APPLIANCE.COM)

Many issues develop due to these problems. For example, nearly all of these devices and appliances provide easily discoverable portals / content / metadata with which to craft extremely convincing social engineering campaigns, even in the absence of technical exploit vectors.

Host Header Attacks & 302 redirects used in concert with malicious DNS records / spoofed or squatted domains can be abused in this manner. An attacker can identify the MERAKI device a victim uses through registration, abuse the API to obtain sensitive metadata, and send the victim to a spoofed site or malicious content purported to be a Meraki Dashboard alert. An attacker can change the dynamic DNS record through a number of vectors (ex. Third party service attacks, local vectors) and effectively “hijack” the user or content being accessed.

Through our DNS harvesting and our undisclosed 0-days, we can establish a complex exploit network and botnet via poor vendor controls (ex. MIRAI) We can also hide exploit code in APIs, persist across multiple appliance types, and abuse multiple dynamic DNS networks.

The DNS zones we have provided are intentionally designed, demonstrably insecure, provide detailed information, and can be abused easily. Registrations can be abused for data exfiltration or beaconing over the vendor’s DNS network. These DYNAMIC DNS services allow for efficient, mass exploitation and recon. The poor controls and “spoofability” of these networks (will demonstrate at another time) allow an attacker to not only FIND vulnerable devices.. but automate mass exploitation via attacks such as those we provided or other common attacks.

The author wishes for this to be noted as responsible disclosure and ethical considerations for the attacks / exploits seriously impacted disclosure dates and continues to.

“Alexa, have you been compromised?” — Exploitation of Voice Assistants in Healthcare (and other business contexts) Onsite Hutch (Justin Hutchens)
Abstract

As voice assistant technologies (such as Amazon Alexa and Google Assistant) become increasingly sophisticated, we are beginning to see adoption of these technologies in the workplace. Whether supporting conference room communications, or even supporting interactions between an organization and its customers — these technologies are becoming increasingly integrated into the ways that we do business. While implementations of these solutions can streamline operations, they are not always without risk. During this talk, the speaker will discuss lessons learned during a recent penetration test of a large-scale “Alexa for Business” implementation in a hospital environment where voice assistants were implemented to assist with patient interactions during the peak of the COVID-19 pandemic. The speaker will provide a live demonstration of how a cyber-criminal could potentially use pre-staged AWS Lambda functions to compromise an “Alexa for Business” device with less than one-minute of physical access. Multiple attack scenarios will be discussed to include making Alexa verbally abuse her users (resulting in possible reputation damage), remote eavesdropping on user interactions, and even active “vishing” (voice phishing) attacks to obtain sensitive information. Finally, the talk will conclude with a discussion of best-practice hardening measures that can be taken to prevent your “Alexa for Business” devices from being transformed into foul-mouthed miscreants with malicious intent.

I used AppSec skills to hack IoT, and so can you Onsite Alexei Kojenov
Abstract

We tend to think of AppSec and IoT as two separate infosec disciplines. Sure, the domain knowledge, attack vectors, and threat mitigation are not exactly the same in those two worlds. At the same time, as the hardware continues to evolve, we see more and more tiny general purpose computers around us. Many of these tiny computers nowadays run software that is written in a conventional programming language, listen on network ports, process data inputs, and communicate with the outside world. These devices can be attacked just like any other application running on a desktop, on a server, or in the cloud.
In this talk, I am going to tell you a story about my hacking journey that unexpectedly took me from device configuration settings to software reverse engineering, vulnerability discovery, and six new CVEs. Together, we’ll go step by step through reconnaissance, firmware analysis, decompiling, code review, and remote debugging. I’ll also share my experience with the responsible disclosure process. I hope this talk inspires you to apply your general hacking skills to new areas such as IoT, even if you’ve never done that before.

You're Doing IoT RNG Onsite Dan "AltF4" Petro and Allan Cecil
Abstract

Think of a random number between '0' and infinity. Was your number '0'? Seriously? Crap. Well unfortunately, the hardware random number generators (RNG) used by your favorite IoT devices to create encryption keys may not work much better than you when it comes to randomness.

In this talk, we'll delve into murky design specs, opaque software libraries, and lots of empirical results. We wrote code for many popular IoT SoC platforms to extract gigabytes of data from their hardware RNGs and analyze them. What we found was a systemic minefield of vulnerabilities in almost every platform that could undermine IoT security. Something needs to change in how the Internet of Things does RNG.

The vulnerabilities are widespread and the attacks are practical. RNG is bad out there - "IoT Crypto-pocalypse" bad.

Strategic Trust and Deception in the Internet of Things Onsite Juneau
Abstract

"Game Theory is the study of choices and strategies made by rational actors, called ""players,"" during times of conflict or competition. It has been used throughout history to map human conflict. Statisticians use game theory to model war, biology, and even football. In this talk, we will model interactions between IoT devices based on strategic trust; how agents decide to trust each other.
The talk will provide an overview of game-theoretic modeling and its application to the IoT landscape. The landscape facilitates deception; players must decide whether or not to trust other agents in the network, and agents may have misaligned incentives. There is a trade-off between information gained and short-term security. This talk will build a framework for predictive and strategic trust where players make decisions based on the incentives of their ""opponents."" This talk will not look at network topology or protocols but will instead look at information exchange and strategy."

MIPS-X - The next IoT Frontier Virtual Patrick Ross, Zoltán Balázs
Abstract

IoT vulnerability research usually involves both static and dynamic analysis of the target device. To aid in this task, researchers typically perform some sort of emulation to enumerate the filesystem as well as run the respective binaries. Luckily, there are tools like QEMU and/or Buildroot to guide our path on the way, but this does not mean the way is smooth.

Our main goal was to create a framework and documentation suitable for MIPS (LE/BE) device research, which can be used in a Dockerized environment to set up as many emulated IoT devices as desired. The goal was to create the least amount of pain and effort to set up the emulation infrastructure. This means, you will have a target MIPS architecture virtual machine running natively with all the binaries, full network stack, debugging tools, and other useful tools. Let the pwning begin!

Mind the Gap - Managing Insecurity in Enterprise IoT Virtual Cheryl Biswas
Abstract

"IoT is an ever-expanding attack surface about which we have many misconceptions and assumptions but for which we have very few policies, regulations or security. These are devices built for one purpose, not meant to be upgraded and rarely if ever patched. As more devices are enabled to connect and communicate online, in the relentless pursuit of innovation, we’ve put the cart before the horse and failed to construct a framework to effectively control and secure the capability created.
Consider this: over 90% of the data in the world was created over the past two years, and current output is roughly 2.5 quintillion bytes per day. As IoT moves into a range of enterprise environments, driven by consumer demand and BYOD desire, Shadow IT becomes Shadow ET, bringing new challenges and risks that our existing compliance and security don’t address or regulate.
Misconfiguration usurps any benefits of eroding segregation as online exposure of both sensitive data and critical systems increases. Adversaries at all levels have been watching, waiting and are making their moves because ignorance isn’t an excuse – it’s an invitation to exploitation.

• Insecure third parties and Shadow IoT risks - what the party of your third party allows without your knowledge or consent
• Different flavors – ET, IIoT, IoHT, OT
Takeaways:
Attendees will understand what makes IoT/ET different from standard equipment we connect, and why we cannot secure them the same way.
Attendees will be alerted to the ongoing and increasing risk of Shadow IT within their networks so they can take action on it

• Think NotPetya. Targeted attack that spread from one laptop globally bringing Maersk down.
• How cryptominers are increasingly leveraging exploits on critical vulnerabilities in enterprise realms and spreading via EternalBlue. Targets include Docker containers, and container escapes.
• Compromised conference equipment. Examine the attack on Polycom HDX video conferencing systems. Thousands exposed externally, many more deployed internally. Polycom systems are linked to each other across different corporate offices globally.
Takeaway: Attendees will be able to understand how an attack could be leveraged against IoT/ET in their enterprise environments

Making it Better: (5 min)
• IoT policy and compliance
• Strong authentication: what do we do better when we know that passwords and certs have failed us
• Automating the identification of IoT – no more hide and seek
• Network segmentation - it only works if we do it
• Automatically securing IoT devices before something happens, not after
• The need for Unified Endpoint Management over Enterprise Mobility Management.
Takeaways: Attendees will have recommendations to bring back they they can action within their environments for increased security posture

Reverse Supply Chain Attack - A Dangerous Pathway To Medical Facilities’ Networks Onsite Barak Hadad and Gal Kaufman
Abstract

The supply-chain attack vector has gained a lot of attention in the passing year. Our talk, however, will present a different type of a supply-chain attack vector -- the reverse supply-chain attack.

The process of a supply chain attack involves an attacker altering code of software, or the hardware of a device, en route to a potential victim. The reverse supply chain attack starts from the other end of the chain -- when a device is removed from a secure network. While IT departments are aware of the importance of wiping the harddrives of PCs, before they are being thrown away, or sold off, they are not fully aware that certain medical devices also withhold sensitive data, and the process to wipe these devices is also non-trivial.

In this talk, we will demonstrate the type of data that can be recovered from the most popular infusion pump -- the BD Alaris Infusion Pump. The recovered data can allow an attacker to infiltrate internal networks of medical facilities and exfiltrate or alter personal patient data. In the process of analyzing this attack vector, we purchased a handful of these used infusion pumps from eBay, which led us to the credentials of internal networks of large hospital facilities all over the US.

Ethics at the Edge: IoT as the Embodiment of AI for Rampant Intelligence Actuation Virtual Ria Cheruvu
Abstract

"In the eyes of a smart device and their human controllers, the world is an immense source of data and power. The expanding Internet of Things ecosystem only adds fuel to this, empowering real-time automatic sensing + actuation posing regulatory dilemmas, easily exploitable definitions of trusted entities (e.g., see the 2021 Verkada hack), and measurements of security, robustness, and ethics that change apropos data in the blink of an eye.

Governance and policing of Internet of Things devices is growing to cover the upcoming trail of destruction by flailing technical solutions, but some intriguing key unanswered questions are starting to reveal themselves.

In this talk, we’ll dive into what the sociotechnical problem of ethics means at the edge in the context of machine learning/artificial intelligence and address these questions:

1. Individual vectors of ethics (“Sustainability is an ethical principle?” “Edge devices have their own definition of fairness and bias different from human concepts?”)
2. Evolving principles and governance for IoT devices, and the importance of accountable anonymity
3. Definitions of trusted entities (“When are users a threat?” “Should humans be out of the loop?”), and how key ethical principles, such as privacy and transparency, can be a double-edged sword in the context of IoT security.
4. Incorporating morality into machines is now a reality (“How do we define a calculus and value alignment for IoT ethics?”) - what are key unconventional ethical concerns for human-centered design?"

IoT devices as government witnesses: Can IoT devices ever be secure if law enforcement has unlimited access to their data? Onsite Jordan Sessler and Anthony Hendricks
Abstract

"A man in Connecticut was arrested after his wife’s Fitbit implicated him in her murder. Prosecutors in Arkansas sought to use data from an Amazon Echo as evidence against a murder suspect. Local police sought access to car, TV, and even refrigerator data to monitor Black Lives Matter protestors—and the FBI did the same thing to help track down suspects in the aftermath of the January 6th, 2021 riot at the U.S. Capitol.


These examples are hardly isolated instances—there are thousands of other cases just like them. And they all speak to an important truth: IoT devices are increasingly being used by law enforcement for investigational purposes and, in some cases, even being made into star witnesses at trial. But law enforcement’s use of IoT devices raises two important questions. First, does allowing the government to use IoT data violate consumer expectations of privacy, particularly at a time when IoT products are being made and marketed with an eye toward information security? Second, are criminal suspects being provided with the same near-limitless access to IoT data for purposes of mounting their legal defense?


The answers to both of these questions are troubling, in large part because the law is inherently back-ward looking and is thus not equipped to grapple with the raw amount of information is now generated. Just as many consumers did not realize several years that their watch or car audio system would be used by law enforcement to track their location 24/7, so lawmakers and judges did not either. For example, the Federal Privacy Act of 1974 never contemplated that, rather than maintaining records, the government would simply buy access to private records—as ICE recently did by purchasing access to CLEAR—or create its own iOS app to ensnare criminals, as the FBI recently did. Likewise, although the Supreme Court noted the private nature of cell phone location data in Carpenter v. United States, this was a 5-4 decision (while RBG was still on the bench) that only applied the Fourth Amendment to historical cell phone GPS data, effectively leaving the law unsettled on many other types of IoT data. This has led courts, including a New York federal court in a case involving Apple, to express concerns that, even where warrants are involved, allowing the government to force companies to produce IoT device data could “result in a virtually limitless expansion of the government’s legal authority to surreptitiously intrude on personal privacy.”


These concerns are heightened by the fact that, although the Federal Rules of Criminal Procedure are supposed provide defendants with equal discovery rights, the Stored Communications Act often prevents defendants from accessing the IoT data of others, such as witnesses, accusers, or potential other defendants. In practice, this means that IoT data can effectively be used against criminal suspects but is not available for them to use in arguing their legal defense. This results in an incredible inequality in the criminal justice system. And it may also lead to erroneous outcomes: as with DNA evidence, IoT data may help exonerate criminals just as often as it implicates them. Indeed, in the Arkansas v. Bates murder case, the prosecution dismissed the charges against the defendant shortly after it obtained the Amazon Echo data, which apparently validated the defendant’s alibi. Similarly, allegations of cheating against low-income students at Dartmouth Medical School were dismissed after IoT data brought into question potentially erroneous remote test monitoring that may have been skewed by poor internet.


So what can we do to reform or limit government use of IoT data? This talk aims to talk through ways in which both the infosec and legal communities can increase their mutual understanding and help drive reform. In the short term, the infosec community can increase security by minimizing, encrypting, or de-identifying data. This can reduce the amount of information that IoT devices collect and, thus, are required to turn over to law enforcement. Over the long-term, the best solution may be to pass new laws or drive new judicial precedent that incorporates an understanding as to what IoT data is, how it is changing expectations of privacy, and how it is being used by law enforcement. Such laws could either limit access to IoT data—enshrining a greater degree of privacy—or set forth procedures delineating when authorities may use it and guaranteeing defendants equal access. Of course, there are other potential solutions and we hope this talk will help launch a broader discussion on how to help the law interact with IoT technology. "

The Journey of Establishing IoT Trustworthiness and IoT Security Foundation Virtual Anahit Tarkhanyan, Dr. Dr. Amit Elazari and Ria Cheruvu
Abstract

The Internet of Things (IoT) ecosystem holds tremendous promise to promote innovation and productivity, and societal benefits. Yet, with increased connectivity, concerns remain with the growing attack surface. While the DFECON community often focuses on the security aspects of these issues, the multidimensional nature of IoT devices and the combination of AI/ML solutions, sparked standardization activities focusing more generally on the concept of “IoT trustworthiness”. This talk will introduce the audience to the latest developments in the IoT Security Policy landscape, proposals for confidence/certifications mechanisms emerging globally, and key IoT Security baseline standards developments, while exploring the connection to the IoT trustworthiness concept across the IoT Supply Chain. We will describe a case study of IoT robustness and trustworthiness applied in context of AI and smart analytics, including the importance of characterizing the behavior of data.
