Bitsquatting: Passive DNS Hijacking

Ed Miles, Security Researcher at DiDi Labs

The Domain Name System is one of the foundational technologies that allow the internet to function, but unfortunately, DNS is surprisingly brittle to certain issues, such as bitsquatting.

Lookups to names that are a "bitflip" away from well-known sites (like '' instead of '' since 'c' and 'a have a single bit difference) can be caused by memory failing due to defect or overheating situations, rogue cosmic rays, or even (allegedly) radiation caused by nuclear reactions.

I was curious how realistic the last case really was - can we 'detect' active nuclear tests based solely on bitsquatting data? To find out, I revisited bitsquatting. First I'll briefly introduce the key concepts required for understanding bitsquatting (including ASCII, DNS and HTTP, Internet infrastructure, and memory error scenarios). I'll show the tools and techniques used to identify and register over 30 newly identified bitsquat domains, monitor DNS and HTTP requests, and process, enrich, and investigate the data. Finally, I will discuss any observations gathered from the data, with a focus on regional trends, specific devices, and current events - and try and see if I could prove any correlation.

In the end, attendees should leave with knowledge of the prevalence of bitsquatting and how it has evolved since the phrase was coined 8 years ago, as well as a few techniques for analyzing bitsquatting data and drawing some interesting conclusions.

Capturing in Hard to Reach Places

Silas Cutler, Senior Security Researcher at CrowdStrike

It's easy for us to take for granted when tools allow us to start capturing network traffic without any real hardships. However, what happens when the data you want isn't so easy to capture. This talk will look at two cases in which environments needed to be bent in order to capture the data needed for analysis.

Car Infotainment Hacking Methodology and Attack Surface Scenarios

Jay Turla, Application Security Engineer at Bugcrowd

The battle for supremacy for the control of the dashboard display or infotainment systems has always been a race. Most of these systems run on Linux, Android, Windows (customized dashboards - perhaps Windows ME or CE) and Blackberry's QNX. In-Vehicle Infotainment (IVI) or In-car entertainment (ICE) Systems are indeed fun consoles where you can play media, movies, or work with your car's navigational system. But somehow it also comes with a risk of being hacked or attacked because they have also been plagued with vulnerabilities. In this talk, join Jay as he presents his own Car Hacker's Methodology in finding security bugs in order to pwn a car's infotainment system without having to do a drive by wire or CANbus hacking tools but will simply point out the common attack surfaces e.g WiFi, Bluetooth, USB Ports, etc. and some scenarios on how to exploit it just like how he popped a shell or issue an arbitrary command in his car which he tweeted in Twitter before.

Ducky-in-the-Middle: Injecting Keystrokes into Plaintext Protocols

Esteban Rodriguez, Security Consultant at Coalfire Labs

This talk will cover the basics of protocol analysis using Wireshark and lead into analyzing two custom application protocols used for extending the mouse and keyboard of a remote system. The two applications covered are HippoRemote, and iOS app to use a iPhone as a trackpad and keyboard, and Synergy, an application to allow for control of multiple operating systems with one mouse and keyboard. By performing a MITM attack, an attacker can abuse this protocols to send keystokes to a remote machine to gain remote code execution similar to a USB rubber ducky attack. The talk will also discuss mitigations and open source code will be provided for exploitation. The target audience should have a basic understanding of Wireshark, ARP spoofing, and reverse shells.

Fishing for Phishers. The Enterprise Strikes Back!

Joseph Muniz, Cisco
Aamir Lakhani, Fortinet

Phishing and social engineering has been around since Han Solo has flown the Millennium Flacon. The typically response is deleting the messages and giving the middle finger however, what more could be done to strike back? This talk will cover how to build an artificial environment and develop anti phishing tools used to respond to phishing attempts. Results could include owning the attacker's box "hypothetically" since some legal boundaries could be crossed.

Joseph Muniz is an architect at Cisco Systems. Aamir Lakhani (Twitter: @SecureBlogger) is a lead researcher at Fortinet. Together, they have spoken at various conferences including the infamous Social Media Deception RSA talk quoted by many sources found by searching "Emily Williams Social Engineering." They are also making their fourth appearance for the DEF CON Wall of Sheep. Both speakers have written books together including a recent title Digital Forensics for Network Engineers released on Cisco Press late February 2018. They have been friends for years and continue to collaborate on research and other projects.

Freedom of Information - Hacking the Human Black Box

Elliott Brink, Senior Penetration Tester at RSM US LLP

FOIA (otherwise known as the Freedom of Information Act or FOI/Freedom of Information in Australia) are government-based initiatives to permit the public to request information on various government records. In practice, these acts enable transparency of the operations of government to the masses with relative ease. In reality, submitting FOI requests can be a cumbersome and frustrating process for citizens.

For two years now I have been hacking this human black box - finding out what you can/cannot ask for and more importantly how to ask for information and get it! Have you ever asked the government for a log file, Cisco IOS running config or Active Directory group policies? Do you ever wonder if a government employee would provide you with such information if you asked really really nicely? Let's find out together! For the past couple of years I have been performing various technology-focused FOI requests in an attempt to answer one simple argument: Can you utilize freedom of information to enumerate technical information from government agencies? I present my research, findings and results of multiple years of submitting FOIA requests to various USA and Australian government institutions including multiple intelligence agencies. We will discover the fun times and challenges when performing such requests.

Attendees will gain practical knowledge about: what FOIA is, the caveats of FOIA, how you can utilize FOIA on red team engagements and other open source intelligence gathering activities and finally the results of my research in multiple requests to intelligence agencies.

Grand Theft Auto: Digital Key Hacking

Huajiang "Kevin2600" Chen, Security Research at Ingeek
Jin Yang, Independent Security Researcher

The security of automobiles accesses control system is a topic often discussed. Today's vehicles rely on key-fob control modules, to ensure the vehicle is accessible to authorized users only. While most traditional automobile key-fob systems have been shown to be insecure in the past, here comes a game changer. Instead of the regular key-fob system, some car owners will be able to access their vehicle by having their smartphone authenticates as a digital car key.In this talk, we will reveal the research and attacks for one of digital car keys system in the current market. By investigating how these features work, and how to exploit it through different possibles of attack vectors, we will demonstrate the security limitations of such system. By the end of this talk, the attendees will not only understand how to exploit these systems also which tools can be used to achieve our goals.

IoT Data Exfiltration

Mike Raggo, CSO of 802 Secure, Inc.
Chet Hosmer, Owner of Python Forensics

IoT offers new protocols and frequencies over which communication travels. Due to lack of familiarity amongst most enterprises, most organizations are ill-equipped to monitor or detect these mysterious channels. This introduces a plethora of covert channels by which data could be exfiltrated, or malware to be infiltrated into the network. In this session we explore this new frontier by focusing on new methods of IoT protocol exploitation by revealing research conducted over the last 2 years. Detailed examples will be provided, as well as demo of a python tool for exploiting unused portions of protocol fields. From our research, we'll also reveal new methods of detecting aberrant behavior emanating to/from these devices gathered from our lab and real world testing.

Mallet: A Proxy for Arbitrary Traffic

Rogan Dawes, Senior Researcher at SensePost

Mallet is an intercepting proxy for arbitrary protocols. More accurately, it is a framework for building proxies for arbitrary protocols. Mallet provides the basics required of all proxies: A way to receive the data, a way to send the data, and a user interface to intercept and edit the data. It builds on the Netty project, and as such has access to a large, well-tested suite of protocol implementations that can be used to transform a stream of bytes into useful, high-level protocol objects. This workshop will introduce attendees to Mallet, and show how to construct pipelines of arbitrary complexity, to successfully decode and intercept messages in various protocols, as well as automating modifications of the various messages. A basic familiarity with Java will enhance the delegate's understanding of what they are taught, but is not a requirement.

Rogan Dawes (Twitter: @RoganDawes) is a Senior Researcher at SensePost and has been hacking since 1998, which, coincidentally, is also the time he settled on a final wardrobe. He used the time he saved on choosing outfits to live up to his colleague's frequent joke that he has an offline copy of the Internet in his head. Rogan spent many years building web application assessment tools, and is credited as having built one of the first and most widely used intercepting proxies, WebScarab.

Mapping Wi-Fi Networks and Triggering on Interesting Traffic Patterns

Caleb Madrigal, Applied Researcher at Mandiant/FireEye

Sure, WiFi hacking has been around for a while, and everyone knows about tools like airmon-ng, kismet, et al. But what if you just want to view a list of all networks in your area along with all devices connected to them? Or maybe you want to know who's hogging all the bandwidth? Or, what if you want to know when a certain someone's cell phone is nearby. Or perhaps you'd like to know if your Airbnb host's IP Camera is uploading video to the cloud?

For all these use-cases, I've developed a new tool called "trackerjacker". In this talk, we'll use this tool to explore some of the surprisingly-informative data floating around in the radio space, and you'll come away with a new skill point or two in your radio hacking skill tree, as well as a new magical weapon... I mean tool.

Microcontrollers and Single Board Computers for Hacking, Fun and Profit


As security researchers, we are always looking for the next device that will make our jobs easier and our research more effective. In many cases, physical gear can be expensive and limited in capability which can be prohibitive, especially in engagements where dead drops are required. However, with the skyrocketing popularity of microcontrollers and single board computers, that barrier has been reduced significantly and has created a host of new possibilities for everything from dead drops to wired and wireless network intrusion and analysis. gh057 will introduce some of the more popular options in this genre and some live demonstrations of their more fun uses. gh057 will demonstrate three devices he built to solve specific problems and that are based on these platforms: ATtiny85, ESP8266 / ES32, Raspberry Pi Finally, and as a bonus, gh057 will demonstrate a simple technique that uses Applescript and Bash that can be used to create a simple USB trojan and can be useful for end-user training.

gh057 has worked on almost every aspect of the software development lifecycle. For the majority of his career, he worked as a front-end, full stack engineer specializing in UI/UX. During this time, he was involved in development and also testing efforts, which included quality and security best practices. In the last few years, gh057 completed a career transition to application security, most notably through security evangelism roles, where he worked closely with development teams. As an application security engineer, gh057 is responsible for security best practices, which encompasses both digital and physical threat vectors. Most recently, gh057 has been the concept creator and team lead for the Day of Shecurity conference which took place on June 16th in San Francisco, CA. In his free time, he is passionate about promoting equality in the cybersecurity industry and offering mentorship to young technologists. His goal is to leave behind a better industry than the one he found when he first began his career.

Normalizing Empire's Traffic to Evade Anomaly-based IDS

Utku Sen, Senior R&D Engineer at Tear Security
Gozde Sinturk, R&D Engineer at Tear Security

Perimeter defenses are holding an important role in computer security. However, when we check the method of APT groups, a single spear-phishing usually enough to gain a foothold on the network. Therefore, red teams are mostly focused on "assume breach" type of scenarios. In these scenarios, testers need to use a post-exploitation framework. Besides that, testers also need to hide the server-agent communication from NIDS (Network Intrusion Detection Systems). In this session, we will discuss one of the most famous post-exploitation tool, Empire's situation against payload-based anomaly detection systems. We will explain how to normalize Empire's traffic with polymorphic blending attack (PBA) method. We will also cover our tool, "firstorder" which is designed to evade anomaly-based detection systems. firstorder tool takes a traffic capture file of the network, tries to identify normal profile and configures Empire's listener in such way.

An OSINT Approach to Third Party Cloud Service Provider Evaluation

Lokesh Pidawekar, Senior Cloud and Application Security Engineer at Cisco

In the era of third party cloud service providers where enterprise critical data is hosted and shared with various vendors, third party security reviews have become essential part of Information Security. It has become a challenge for security teams to ensure parity is maintained between security controls that are available on premise, to those offered by the cloud provider. Typically, companies send a word document or excel sheet to get answers from cloud providers, however, this process is done only once and the review is point in time. In this talk, the attendees will learn about various methods of identifying security posture of the third-party cloud service using information available on Internet, how to use this information for performing cloud service review and improve their own cloud offerings. This can also supplement the tedious questionnaire process and provide an option to fast track the vendor reviews.

Lokesh Pidawekar (Twitter: @MaverickRocky02) work as Senior Cloud and Application Security Engineer in Cisco InfoSec team where he is responsible for designing secure architecture for applications, evaluating third party cloud service providers, and providing training to enterprise architects.

PacketWhisper: Stealthily Exfiltrating Data and Defeating Attribution Using DNS and Text-Based Steganography


Data exfiltration through DNS typically relies on the use of DNS query fields to exfiltrate data via the attacker's DNS server. This approach has several shortcomings. The first is attribution, since attackers end up creating a trail back to their own infrastructure. The second is awareness, as DFIR analysts have made careful study of DNS fields as exfiltration vectors. The third is access, since companies are increasingly using DNS server whitelisting to prevent or alert on outgoing DNS queries to servers controlled by attackers. But what if data could be transferred using the target's own whitelisted DNS servers, without the communicating systems ever directly connecting to each other or a common endpoint? Even if the network boundary employed data whitelisting to block data exfiltration?

Through a combination of DNS queries and text-based steganography, we'll cover the methods used to transfer data across a network, hidden in plain sight, without direct connectivity between systems, while employing multiple levels of deception to avoid generating alerts as well as to mislead analysis attempts. The presentation will include a demonstration of PacketWhisper, a new tool written in Python, that automates all of these steps for you. PacketWhisper will be made available on GitHub to coincide with this session (

Protecting Crypto Exchanges from a New Wave of Man-in-the-Browser Attacks

Pedro Fortuna, CTO and Co-Founder of Jscrambler

In the last year or so, we have seen a massive increase in the value of cryptocurrencies and the emergence of hundreds of new coins and ICOs, getting millions of people into an investment frenzy. A lot of them being non-technical regular consumers that rushed to create new accounts in the most popular crypto exchanges like Coinbase or Bitstamp. Crypto exchanges are naturally appealing for attackers and have been targeted since as long as we can remember. However, since last year, they are also being targeted by Man-in-the-Browser (MITB) attacks. Malware families such as Zeus Panda, Ramnit and Trickbot are already aiming at websites such as or In this talk, we will detail how these attacks work, from account takeover to moving out the coins to attacker-controlled wallets. We'll discuss current defenses e.g. multi-factor authentication or strong SSL encryption and why they are failing to mitigate this type of attacks.

Rethinking Role-Based Security Education

Kat Sweet, Duo Security

How do we scale a deeper level of security awareness training without sacrificing efficacy? This talk will explore strategies and tactics for developing security education based on employees' roles, access, and attack surface while designing not only for efficiency but also for effectiveness. By prioritizing the highest-risk teams, pooling teams to collaboratively threat-model, and contextualizing universal truths of security hygiene to those threat models, we can deliver training that leverages employees' roles, fosters retention via active participation, and eases the burden on trainers within the security team. Attendees will walk away with a roadmap for building scalable, contextual, and collaborative role-based employee security education within their organizations.

Ridealong Adventures: Critical Issues with Police Body Cameras

Josh Mitchell, Principal cybersecurity Consultant at Nuix

The police body camera market has been growing in popularity over the last few years. A recent (2016) Johns Hopkins University market survey found 60 different models have been produced specifically for law enforcement use. Rapid adoption is fueling this meteoric increase in availability and utilization. Additionally, device manufactures are attempting to package more and more technology into these devices. This has caused a deficiency in local municipalities' skills and budget to accurately assess the attack surface and exposure to the organization. Furthermore, departmental policies and procedures governing the secure deployment of these devices is largely insufficient.

At DEF CON, we will be introducing tactics, techniques, and procedures to assess the security of these devices. We will cover attacks against the physical devices, RF components, smartphone app's, and desktop software. The capabilities demonstrated and discussed will encompass publicly and privately available technologies. Additionally, the talk will cover multiple products and vendors, shedding light on industry wide issues and trends. Finally, we will be releasing software to detect and track various devices and tie these issues into real world events.

Target-Based Security Model

Garett Montgomery, Principal Security Research Engineer at BreakingPoint (Ixia/KeySight)

Have you ever been asked 'what is the best way to protect against $ATTACK'? (usually shortly after $ATTACK makes headlines). Have you ever been challenged to provide the reasoning behind your suggestion? If you were in a room full of experts, would your reasoning hold up under scrutiny? When you discuss with your security-savvy peers, you're quickly come to a consensus on the 'best' control (!= device) to protect against $ATTACK. But do you know WHY it's the 'best'? The Target-Based Security Model is essentially a framework that breaks down attacks to their component level. This breakdown makes it easy to see what the 'best' security controls are - as well as alternative security controls that could also be applied. Its not so much something new, as it is a new way for the industry to communicate about security. In much the same way that the OSI model allows for developers to know they are talking about the same thing, a common security model allows security professionsals to communicate in a vendor-agnostic manner. Think of it as a translation tool for vendor-speak. In this talk we'll present the Target-Based Security model and discuss the following: how it came to be, what it is, and how to use it. And of course, we'll talk about how it can be used to make the world a better place - provided we all agree to use it.

Turning Deception Outside-In: Tricking Attackers with OSINT

Hadar Yudovich, Security Researcher at Illusive Networks
Tom Sela, Head of Security Research at Illusive Networks
Tom Kahana, Security Researcher at Illusive Networks

Deceptions use attackers' own tactics to force them to reveal themselves. Deception techniques are typically used inside the network once attackers have broken in. Once inside, attackers use credentials to move laterally. But before penetrating their target, attackers often study publicly available data to plan their attack. Can we assume that attackers continue to use public information once they've broken in? Could externally-planted deceptions expand our range of visibility on the adversary's activity? In this session, we will present research we conducted to answer these questions, and introduce a tool you can use to "try it at home." We first took a deeper look at various OSINT resources-social media, paste sites, public code repositories, etc.-to refine our picture of the types of publicly-available data, attackers might use to further an attack. Then we planted various deceptive information. For example, on PasteBin we created a fake "paste" page containing a dump of fake credentials. On GitHub we created a fake repository of code containing "accidental" commits (git commit -am 'removed password'). Next, we paired these deceptions with relevant data and user objects within a simulated network environment. We then started monitoring and waited for an attacker to bite.

What Do You Want to be When You Grow Up?

Damon "ch3f" Small, Technical Director at NCC Group North America

Many industries have well-defined points of entry and well-understood education and training requirements. Information Security is not one of those industries. Successful infosec pros often have wildly diverse backgrounds so it is difficult to know which is the "correct" way to enter this field. As our industry has evolved and matured, what do organizations now look for in a candidate? What combination of skills, experience, and education will get you in your "dream job?" SPOILER - there are many predictors of success, and organizations have different priorities, so there is no single answer.

The speaker will describe his experiences as a 22-year veteran of IT and infosec, both from the perspective of working for internal support teams and as a client-facing consultant. In addition to direct observations, this presentation will include the perspectives of other infosec pros that currently work in various capacities in our industry. The goal is not to answer the question of how to successfully develop one's career, as such, but rather to continue the dialogue of what is important to us as we develop our future experts and leaders.

wpa-sec: The Largest Online WPA Handshake Database

Alex Stanev, CTO of Information Services at JSC

Started as pet project in 2011, wpa-sec collects WPA handshake captures from all over the world. Contributors use client script to download handshakes and special crafted dictionaries to initiate attack against PSKs. With more than 115 GB captures from 240 000 submissions, collected samples represent invaluable source for wireless security research. This includes:

  • Many improvements for emerging wireless security tools like hcxtools suite (
  • Identified default PSK key generation algorithms, used by various ISPs. Those, along with fixes for current implementations get in RouterKeygen project ( Many more to come, based on current research activities
  • Performance optimizations for WPA crackers
  • Identified some linux kernel driver bugs

During the talk I will explain how wpa-sec works, provide statistics and a lot internals on optimization and how to use the database as OSINT source during pentests and red team actions.

wpa-sec is opensource project available at

Workshops Schedule




Advanced APT Hunting with Splunk

You wanna learn how to hunt the APTs? This is the workshop for you. Using a real-worldish dataset, this workshop will teach you how to hunt the "fictional" APT group Taedonggang. We discuss the Diamond model, hypothesis building, LM Kill Chain, and Mitre Att&ck framework and how these concepts can frame your hunting. Then we look deep in the data using Splunk and OSINT to find the APT activity riddling a small startup's network. We walk you through detecting lateral movement, the P of APT, and even PowerShell Empire. Then at the end, we give you a similar dataset and tools to take home and try newly learned techniques yourself.

Mallet, an intercepting proxy for arbitrary protocols

Mallet is an intercepting proxy for arbitrary protocols. More accurately, it is a framework for building proxies for arbitrary protocols. Mallet provides the basics required of all proxies: A way to receive the data, a way to send the data, and a user interface to intercept and edit the data. It builds on the Netty project, and as such has access to a large, well-tested suite of protocol implementations that can be used to transform a stream of bytes into useful, high-level protocol objects.

This workshop will introduce attendees to Mallet, and show how to construct pipelines of arbitrary complexity, to successfully decode and intercept messages in various protocols, as well as automating modifications of the various messages.

A basic familiarity with Java will enhance the delegate's understanding of what they are taught, but is not a requirement.

Rogan spent many years building web application assessment tools, and is credited as having built one of the first and most widely used intercepting proxies, WebScarab.

Kali Dojo Workshop

Kali Linux can be deeply and uniquely customized to specific needs and tasks. In this workshop, we will customize Kali Linux into a very specific offensive tool, and walk you through the process of customization step by step. We will create a custom Kali ISO that will: load very specific toolsets; define a custom desktop environment and wallpaper; leverage customized features and functions; launch custom tools and scripts; install Kali automatically, without user intervention as a custom "OS backdoor". This workshop will guide you through all the aspects of Kali customization and give you the skills to create your own highly-customized Kali ISO, like the much feared Kali "ISO of Doom".

Kali Live USB With Persistence And LUKS (2.5hrs)

In this section we will show you how to deploy your customized Kali ISO to a secure, encrypted, USB device. ➤ We will show you how to add standard and encrypted USB persistence so you can save your data and we will walk you through a custom LUKS "nuke" deployment that will obliterate your encrypted data when presented with a specific kill phrase. We will also will discuss strategies to help you safely and legally cross international borders with your encrypted data without compromising it. When you complete this course, you will have the skills to create a completely customized, powerful, portable Kali ISO or USB with full encryption, persistence and the peace of mind of LUKS nuke. And, to sweeten the deal, we will provide super-cool custom Kali-branded USB drives.
