PHV Talks Abstracts and Bios

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.

Mike Raggo (Twitter: @DataHiding) is Chief Security Officer at 802 Secure and has over 20 years of security research experience. His current focus is wireless IoT threats impacting the enterprise.

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.

Utku Sen (Twitter: @utkusen) is a security researcher who is mostly focused on following areas: application security, network security, tool development.

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.

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.

Hadar (Twitter: @hadar0x) is a Security Researcher at Illusive Networks.

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.

Damon Small (Twitter: @damonsmall) began his career studying music at Louisiana State University. Pursuing the changing job market, he took advantage of computer skills learned in the LSU recording studio to become a systems administrator in the mid 1990s. Over the past 18 years as a security professional he has supported infosec initiatives in the healthcare, defense, aerospace, and oil and gas industries. In addition to his Bachelor of Arts in Music, Small completed the Master of Science in Information Assurance degree from Norwich University in 2005. His role as Technical Director includes working closely with NCC Group consultants and clients in delivering complex security assessments that meet varied business requirements.

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

Text of the Opening Remarks / Introduction at the Speaker Workshops (DEF CON 25)

Good morning and welcome to the Packet Hacking Village at DEF CON 25 in Las Vegas, Nevada! We cannot thank you enough for your support and for your continuing support for all these years. The Wall of Sheepʼs mission is and has always been security awareness. This year, the Packet Hacking Village have a number of events and learning opportunities including the venerable Packet Detective and Capture The Packets. We have a fantastic slate of DJs to entertain and keep this village lively. Sheep City and Honeypots have returned this year.  We are also excited for something new this year: hands-on workshops as there is a tremendous demand for training and continuing education in this cyber security. We hope that you will take advantage of the many opportunities here at the Packet Hacking Village and ultimately at DEF CON to learn, to collaborate, and to be inspired.

And of course, here we are at the Speaker Workshops. This is a special year: this is the fifth anniversary of the Speaker Workshops at the Packet Hacking Village. We are going to kick it off right-off-the-bat with a very special keynote. Dan Geer said in his keynote at Black Hat 2014: "cyber security is now a riveting concern, a top issue in many venues more important than this one." Or as Matt Blaze said bluntly at The Eleventh HOPE: "we are in a national cybersecurity crisis." So what does this have to do with our keynote? There are many people now starting to study or entering the field of cyber security which is very welcoming to see. However, the body of knowledge is now too deep and intimidating to grasp and history is easily forgotten. So how did we get into the mess we are in now? In May of 1998, a group of hackers testified in front of a panel of US Senators. The hacker group was L0pht. One of the members of L0pht who testified was Weld Pond, Chris Wysopal. L0pht warned that the Internet, software, and hardware are not safe and security is an afterthought. Their warning was a disaster foretold and tragically ignored (please read the stellar Washington Post article "A Disaster Foretold --And Ignored"). Their warning and efforts also paved way for many of our careers and lifestyles in this field, and why most of us are here today at DEF CON. It is my fantastic honor to introduce you all to Chris Wysopal.

Packet Hacking Village Equipment Check for DEF CON 24

[Written by @donds.  Originally posted at]

They say not to bring any electronic devices at DEFCON!? .... what's the fun in that? Well, your mother also said not to get in a strange car with a stranger... UBER, anyone?

It’s time to prep your gear for the Packet Hacking Village (PHV) at DEFCON 24. Although, the PHV staff will have some gear for you to use, I highly recommend to bring your own "FOR DEFCON USE ONLY" gear. 

For the Wall of Sheep and WiFi Sheep Hunt you'll need a laptop with wired and wireless sniffing capabilities.  I spent about $200 for a used laptop from eBay. Also invested on an Alpha wireless USB card from Amazon. Load Kali on the laptop and you're basically good to go. Most tools you'll need are already included in Kali.  The PHV staff can help you refine your setup and config depending on what event you want to try out.

For Sheep City, you can use the same laptop you plan to use for WoS and WIFISH.  But it will require a bit more creativity and possibly a visit to the vendor area or Fry's.  Prep for Bluetooth, ZigBee, IrDa, RF...etc. Be ready for anything.

Packet Detective runs like a classroom format. IMHO, this is a "MUST DO" event at PHV. PHV will have laptops setup for PD Agent trainees to use... Yes, you don't have to bring your own laptop to participate.  This is a very popular event and laptops are limited. Sign up early.

WiFi Sheep Hunt will also have a sign-up sheet for the FoxHunt gear. You can use your own equipment to join the FoxHunt and code breaking fun.  There will also be a couple of laptops for players to use, but only for limited time slots. 

Capture the Packet has produced Black Badge winners at DEFCON. If you're just prepping now, you're already behind... you get my drift.

If you're asking which one to do first, I'd say do it all! But if it's your first ever visit at PHV, here's the order of events I'd suggest..

1. Packet Detective
2. Wall of Sheep
3. WiFi Sheep Hunt
4. Sheep City
5. Capture The Packet

First Round of Accepted Speaker Workshops at DEF CON 24

The Arizona Cyber Warfare Range: Learn by Destruction

Richard Larkins, Network Architect at Arizona Cyber Warfare Range and President of the ISSA Phoenix Chapter

Want to run all those tools you have always heard about, but don't have the hardware to do it? Or - does your Boss want you to learn NMap, but won't let you run it on any of the corporate networks? This presentation will show what can happen when a couple of dedicated and slightly unbalanced individuals come together to establish the largest volunteer staffed, donation funded Cyber Offensive and Defensive Training facility in the world. Attendees will be shown how real hardware and real tools can be used remotely to further increase their Cyber talents.

Rich Larkins (Twitter: @arahel_jazz) is a Network Systems Engineer with way too many expired Cisco certifications. He has touched networks on 4 out of the 7 continents, over 10 countries, and is currently working on his third global satellite constellation ground control system. To further make life more unbearable, he has undertaken the role of network architect for the Arizona Cyber Warfare Range, which requires listening to hackers playing horrendous techno music at loud enough levels to drown out all the equipment in the room. Rich's real bright spot in life is his wife of 23 years, Patricia, and their two Cocker Spaniel rescue dogs (Luna and Orion) who have seven legs between them. You do the math.

Attacks on Enterprise Social Media

Mike Raggo, Chief Research Scientist at ZeroFOX

Current threat vectors show targeted attacks on social media accounts owned by enterprises and their employees. Most organizations lack a defense-in-depth strategy to address the evolving social media threat landscape. The attacks are outside their network, commonly occur through their employee's personal accounts, and circumvent existing detection technologies. In this presentation we'll explore the taxonomy of social media impersonation attacks, phishing scams, information leakage, espionage, and more. We'll then provide a method to categorize these threats and develop a methodology to adapting existing incident response processes to encompass social media threats for your organization.

Michael T. Raggo (Twitter: @MikeRaggo) has over 20 years of security research experience. Michael is the author of “Mobile Data Loss: Threats & Countermeasures” and “Data Hiding: Exposing Concealed Data in Multimedia, Operating Systems, Mobile Devices and Network Protocols” for Syngress Books, and contributing author for “Information Security the Complete Reference 2nd Edition”. A former security trainer, Michael has briefed international defense agencies including the FBI and Pentagon, is a participating member of FSISAC/BITS, and is a frequent presenter at security conferences, including Black Hat, DEF CON, Gartner, RSA, DoD Cyber Crime, OWASP, HackCon, and SANS.

Connections: Eisenhower and the Internet

Damon "Chef" Small, Technical Project Manager at NCC Group

"Rise of the Machines" conjures thoughts of the evolution of technology from the exclusive domain of computer scientists in the early days of our industry to including everyday people using - and often wearing - Internet-connected devices. With that theme in mind, the speaker researches the history of one large, government-funded infrastructure and compares it to another. Specifically, the Eisenhower Interstate System and the Internet. "Connections: Eisenhower and the Internet" explores what the logistical challenges of moving vehicles across the Country can teach us about cybersecurity. Although these two topics seem unrelated, the speaker will take the audience on a journey that begins with early 20th century road-building projects, travels through ARPANET and the commercialization of the Internet, and arrives at current-day cyberspace. These two massive infrastructures have changed the world, and there are important lessons that the former can teach about the latter. The presentation concludes with predictions about the future of the the Information Superhighway and how information security professionals can prepare.

Chef (Twitter: @damonsmall) earned his handle from his use of cooking metaphors to describe infosec concepts to laypeople. He began his career studying music at Louisiana State University and took advantage of computer skills learned in the LSU recording studio to become a systems administrator in the mid 1990s. Following the dotcom bust in the early 2000s, Chef began focusing on cyber security. This has remained his passion, and over the past 16 years as a security professional he has supported infosec initiatives in the healthcare, defense, and oil and gas industries. In addition to his Bachelor of Arts in Music, Chef completed the Master of Science in Information Assurance degree from Norwich University in 2005. His role as Technical Project Manager at NCC Group includes working closely with consultants and clients in delivering complex security assessments that meet varied business requirements. Recent speaking engagements include DEFCON 23, BSides Austin, BSides San Antonio, HouSecCon, and ISSA Houston.

Deceive and Succeed: Measuring the Efficiency of a Deception Eco-System in Post-Breach Detection

Omer Zohar, Head of Research at TopSpin Security

Today's networks are undergoing all sorts of sinister attacks from numerous sources and for myriad reasons. Security at the perimeter is inadequate for thwarting today's highly intelligent attacks as hackers routinely breach the perimeter and gain entry. It isn't long before the network is compromised and critical information is stolen. We must now assume that, despite significant investments in prevention, breaches are going to happen. An additional approach is required. Security teams must go on the offensive, creating a web of non-stop, real-time detection operations using multiple vectors against an ever-changing landscape of cyber threats. Deception technology now plays a critical role. Used as a strategy for many centuries in actual warfare, the concept of deception is becoming a significant weapon in network-protection schemes. Deception technology doesn't rely on known attack patterns and monitoring. Instead, it employs very advanced luring techniques to entice attackers away from valuable company assets and into pre-set traps, thus revealing their presence. It is able to detect threats in real time without relying on any signatures, heuristics or complex behavioral patterns. But how effective is a deception strategy in detecting breaches? What method works best? How does it integrate with current security operations already in place?

In this talk we will present findings from a first ever research which measured the efficiency of proactive deception using mini-traps and decoys in real-life threat scenarios. We have reconstructed a real enterprise environment complete with endpoints, servers, network traffic and data repositories as well as security tools such as IDS, firewall, SIEM etc. The deception layer was then integrated into the environment in 2 steps: (a) by placing decoys in the network and (b) by placing mini-traps on the assets which point to the decoys, set false credentials, trigger silent alarms and more. We then evaluated the effectiveness of the mini-traps and decoys against both automated, machine-based attacks as well as against sophisticated human attacks: The first stage involved checking the behavior of a variety of malware families against the environment and measuring the deception layer's success in detecting their activity. For the second phase, we invited red-team professionals and white hat hackers to employ real techniques and advanced tools with the task of moving laterally in the environment and exfiltrate high value data.

Omer Zohar has over a decade of experience as a developer and researcher in the data security market. As head of Research for TopSpin Security he is responsible for the research of malware and post-breach detection methods and for defining advanced detection schemes.

Dynamic Population Discovery for Lateral Movement Detection (Using Machine Learning)

Rod Soto, Senior Security and Researcher at Splunk UBA
Joseph Zadeh, Senior Security Data Scientist at Splunk UBA

The focus of this presentation is to describe ways to automate the discovery of different asset classes and behavioral profiles within an enterprise network. We will describe data driven techniques to derive fingerprints for specific types of individual and subgroup behaviors. The goal of these methods is to add context to communications taking place within an enterprise as well as being able to identify when certain asset profiles change there behavioral fingerprint in such a way as to indicate compromise. The type of profiles we want to discover can be tied to human behavior (User Fingerprinting) or particular asset classes like WebServers or Databases (Hardware/Software Fingerprinting). Finally enriching these profiles with a small amount of network context lets us break down the behaviors across different parts of the network topology.

These techniques become important when we want to passively monitor for certain attacks against server hardware even without visibility into the local logs running on the server. For example we will cover the automated discovery and enrichment of DMZ assets and how we use these techniques to profile when a server has been planted with a Webshell or when an asset has been used to covertly exfil data. The methods we propose should be generic to apply to a wide variety of any kind of Layer 4/ Layer 7 traffic or just PCAP data alone.

Rod Soto (Twitter: @rodsoto) has over 15 years of experience in information technology and security. Currently working as a Security Researcher at Splunk User Behavioral Analytics. He has spoken at ISSA, ISC2, OWASP, DEF CON, Hackmiami, Bsides and also been featured in Rolling Stone Magazine, Pentest Magazine, Univision and CNN. Rod Soto was the winner of the 2012 Black Hat Las Vegas CTF competition and is the founder and lead developer of the Kommand & KonTroll competitive hacking Tournament series.

Previously, Joseph was part of the data science consulting team at Greenplum/Pivotal helping focused on Cyber Security analytics and also part of Kaiser Permanente's first Cyber Security R&D team.

HTTP/2 & QUIC - Teaching Good Protocols To Do Bad Things

Catherine (Kate) Pearce, Senior Security Consultant at Cisco Security Services
Vyrus, Senior Security Consultant at Cisco Security Services

The meteoric rise of SPDY, HTTP/2, and QUIC has gone largely unremarked upon by most of the security field. QUIC is an application-layer UDP-based protocol that multiplexes connections between endpoints at the application level, rather than the kernel level. HTTP/2 (H2) is a successor to SPDY, and multiplexes different HTTP streams within a single connection. More than 10% of the top 1 Million websites are already using some of these technologies, including much of the 10 highest traffic sites. Whether you multiplex out across connections with QUIC, or multiplex into fewer connections with HTTP/2, the world has changed. We have a strong sensation of Déjà vu with this work and our 2014 Black Hat USA MPTCP research. We find ourselves discussing a similar situation in new protocols with technology stacks evolving faster than ever before, and Network Security is largely unaware of the peril already upon it. This talk briefly introduces QUIC and HTTP/2, covers multiplexing attacks beyond MPTCP, discusses how you can use these techniques over QUIC and within HTTP/2, and discusses how to make sense of and defend against H2/QUIC traffic on your network. We will also demonstrate, and release, some tools with these techniques incorporated.

Catherine (Kate) Pearce (Twitter: @secvalve) is a Senior Security Consultant for Cisco, who is based in Wellington, New Zealand. Formerly a Security Consultant for Neohapsis in the USA, she has engaged with a widespread and varied range of clients to assist them in understanding their current security state, adding resilience into their systems and processes, and managing their ongoing security risk. Day-to-day she undertakes a mix of advising clients around their security, client-focused security assessments (such as penetration tests), and security research. She has spoken at her work at many security conferences, including Black Hat USA, Source Boston, Nolacon, Kiwicon, ACSC and several others. While she has recently presented on Network Security, her true loves are application security enablement, complex systems security, and cross-discipline security analogues.

Carl Vincent (Twitter: @vyrus001) is a Customer Solutions Consultant for the recently consolidated Cisco Security Solutions group, where he performs a variety of security assessment types. As an information security professional, as well as personal hobbyist, his passion is to continually research ever increasingly elaborate methods of elegantly executed hypothetical crime. He also practices personal information warfare, and most of his biographic details online are somewhat exaggerated.

Now You See Me, Now You Don't

Joseph Muniz, Architect and Researcher at Cisco
Aamir Lakahni, Senior Security Researcher at Fortinet

Many people leave behind bread crumbs of their personal life on social media, within systems they access daily, and on other digital sources. Your computer, your smartphone, your pictures and credit reports all create a information rich profile about you. This talk will discuss all the different threats that leak your information and how attackers can use open source intelligence to find you. We will discuss techniques used by law enforcement and private investigators to track individuals. Learn how you can protect your online footprint, reduce your digital trail, and securing your privacy.

Joseph Muniz (Twitter: @SecureBlogger) is a architect at Cisco Systems and researcher. He has extensive experience in designing security solutions for the top Fortune 500 corporations and US Government.

Presenting Security Metrics to the Board / Leadership

Walt Williams

The board of directors and corporate leadership is not interested in how many attacks your firewall has blocked, and frankly, that is not a metric, that is a measure. Difference between metrics and measurements, how metrics are constructed, and the kinds of metrics the board of directors are interested in will be discussed. In other words, how to identify how to align security metrics with business goals and objectives. The use of frameworks such as ISO 27004 to construct metrics, the pragmatic framework and its uses will also be discussed.

Walt Williams (Twitter: @LESecurity) CISSP, SSCP, CPT has served as an infrastructure and security architect at firms as diverse as GTE Internetworking, State Street Corp, Teradyne, The Commerce Group, and EMC. He has since moved to security management, where he now manages security at Lattice Engines. He is an outspoken proponent of design before build, an advocate of frameworks and standards, and has spoken at Security B-Sides on risk management as the cornerstone of a security architecture. He maintains a blog on security metrics and has presented to boards of three different organizations in diverse industries.

Vulnerability Management: No Excuses, A Network Engineer's Perspective

Richard Larkins, Network Architect at Arizona Cyber Warfare Range and President of the ISSA Phoenix Chapter
Anthony Kosednar, Chief Software Engineer at AZCWR

Vuln Management encompasses 3 out of the top 4 items in the SANS 20 and is a critical item for PCI DSS. Yet, so few companies manage to do it correctly. This presentation will cover the result of the author (a network geek) being unceremoniously thrown into one of those situations, and will detail the lessons learned from it. Tools used: NMap, Tripwire, Qualys, and Crayons.

Rich Larkins (Twitter: @arahel_jazz) is a Network Systems Engineer with way too many expired Cisco certifications. He has touched networks on 4 out of the 7 continents, over 10 countries, and is currently working on his third global satellite constellation ground control system. To further make life more unbearable, he has undertaken the role of network architect for the Arizona Cyber Warfare Range, which requires listening to hackers playing horrendous techno music at loud enough levels to drown out all the equipment in the room. Rich's real bright spot in life is his wife of 23 years, Patricia, and their two Cocker Spaniel rescue dogs (Luna and Orion) who have seven legs between them. You do the math.

Anthony Kosednar (Twitter: @akosednar) is an Information Security Engineer with a background in Aerospace. By day he helps secure corporations and large events (such as Super Bowl XLIX). By night, he puts on the cape of software architect for the Arizona Cyber Warfare Range. Through the darkness of night he helps program the systems that operate the range.

You Are Being Manipulated

GrayRaven, Senior Software Engineer at Cisco Systems

You are being manipulated. There is constant pressure coming from companies, people, and attackers. Millions are spent researching and studying your weaknesses. The attack vectors are subtle. Most times we don't realize that manipulation has occurred until it is too late. Fear not, we can harden our defenses. We can put safeguards in place to help avoid being the victim. For me, the answer came from an unlikely source: my daughter. Small children are fantastic. Society has not yet influenced their development; therefore, children are relentless in pursuing their aims. Since they are naive to right and wrong, they will use any tool available to get their goal. How does this help? My daughter became my trainer, and this talk discusses how interacting with her has improved my defenses. Comparing her strategies to real world examples will show how to build a training framework of your own. Access to small children is not needed.

GrayRaven (Twitter: @_grayraven_) is a senior software engineer at Cisco Systems. He has been fascinated with manipulation since his childhood. Despite receiving a degree in psychology, he spent 18 years as a professional in the Information Technology space. GrayRaven spent the first seven years of his career as a system and network administrator before moving to the dark art of programming. Two years ago he stopped dabbling and tumbled down the security rabbit hole. This journey makes him believe that he is finally using his degree professionally. During his downtime, GrayRaven can be found practicing martial arts, brewing beer and mead, or writing.
