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.
It's that time of the year again. Our team will be in Las Vegas at DEF CON which means there will be no one to process online orders. There will be no orders processed from July 20th 2017 - August 5th 2017.
Wall of Sheep Team
We are pleased to announce a series of hands-on workshops at the Packet Hacking Village at DEF CON 25.
Why Are We Doing This: Because of the success of our Packet Detective and Capture The Packet events, and knowing the demand for hands-on workshops in cyber security, we are expanding our Packet Hacking Village this year to have hands-on workshops.
Location: This hands-on workshops area is will have 30 computers preloaded with the necessary tools so you will not need to bring your own laptop. Our hands-on workshops area will be directly across from the Speaker Workshops room.
Registration will cost $10 USD with 100% of the proceeds benefiting Hackers for Charity; this will help ensure only interested people register, will actually attend and help a great charity.
Attendees that are late to the class forfeit their seat. This is non-negotiable and non-refundable so be on-time!
You need to register to reserve a seat.
You *MUST* have a DEF CON badge to enter the event and the printed ticket from your registration for entry into the workshop area.
Any fakes/hacks/scams/social engineers will be publically shamed in true DEF CON fashion.

Advanced Implant Detection with Bro and PacketSled
Aaron Eppert, Director of Engineering for PacketSled
With the release Double Pulsar by the Shadow Brokers malicious software ranging from EternalBlue, WannaCry, to the more recent (Not)Peyta cyberattacks have necessitated a deeper understanding of the SMB protocol found in virtually every network in the world. Given the extreme complexity of SMB it is very easy for C&C activity to go undetected due to the shear signal-to-noise ratio present in the protocol and the high volume of activity that it generates on a network without malicious activity being present. For this PacketSled extended the SMB analyzer in Bro to facilitate the detection of, what would generally be, anomalous behavior of the protocol itself, bringing the noise floor down and allowing for the detection of anomalous activity.
What is Bro? Bro is a powerful network analysis framework that allows for customized development via an internal scripting language that allows the creation of highly powerful detections via metadata extraction events.
Aaron Eppert (Twitter: @aeppert) is the Director of Engineering and lead developer of PacketSled’s core Sensor technology. Aaron has commits to the Bro Core project and resurrected the SMB Analyzer from the depths of a feature branch and has since extended it for the purposes of finding modern malware. Additionally, Aaron has two decades of experience reverse engineering network protocols and malware as well as developing as well as developing low-level software in a range of languages. Aaron has developed and presented Bro-centric trainings to Fortune 500 companies, and government organizations.
Introducing Mallet: An Intercepting Proxy for Arbitrary Protocols
When it comes to HTTP interception, the tools of the trade are excellent. However, setting up an intercepting proxy for protocols other than HTTP can be time consuming and difficult. To address this gap, we've created a new proxy, which allows you to define a new protocol on the fly using Netty's built-in protocol encoders and decoders, as well as being able to create your own using the existing Netty libraries. Once defined, you can interact with the objects in real-time, modifying objects and properties as you see fit. This workshop will give you hands on experience with our new proxy.
Dane Goodwin (Twitter: @@dane_goodwin) has worked as a pentester for ~4 years, after deciding a career in development wasn't for him. He's presented some coolness at ZaCon, BSides Cape Town, and BlackHat Arsenal 2016. While not cycling, he currently spends his time learning all things SDR.
Introduction to 802.11 Packet Dissection
Megumi Takeshita, aka Packet Otaku, Ikeriri Network Service Co.,Ltd.
Have you ever wanted to capture, filter, examine, visualize, decrypted and followed sequences of 802.11 packets? This workshop demonstrates a typical and basic work flow of wireless packet analysis. This workshop will cover basic wireless packet analysis, using Wireshark, to examine the internals of 802.11 frames including the Radiotap header, looking at the importance and meaning of the fields, mark packets and understand processes of the link layer, input the decryption key for WPA2 to explore WPA2-PSK frames and how to create graphs to visualize the stats of a wireless network.
Megumi Takeshita, or Packet Otaku (Twitter: @ikeriri) runs a packet analysis company, Ikeriri Network Service, after having worked at BayNetworks and Nortel Networks in Japan.

Linux Lockdown: Jailing Programs with Linux Containers
Jay Beale, CTO and COO at InGuardians
Taught by Bastille Linux creator Jay Beale, this hands-on workshop will teach you to use Linux containers to better contain an attack on any program running on the system. You will be given a vulnerable program to protect, via a virtual machine that you can download beforehand. You will first compromise the application, then contain it and exploit it again. We'll discuss AppArmor, seccomp and SELinux, and you'll be able to download the virtual machines to try more advanced versions of this afterward. For purposes of ease, we'll use Docker, but you can take the concepts home and try them with LXC/LXD, runc, or another framework for managing containers. This workshop is being taught for the first time and provides one topic from the long-running Black Hat class, "Aikido on the Command Line.”
Jay Beale (Twitter: @jaybeale and @inguardians) has been working in Linux security since 1999, when he began creating several defensive security tools, including Bastille Linux/UNIX and the CIS Linux Scoring Tool, both of which were used widely throughout industry and government. He has served as an invited speaker at many industry and government conferences, a columnist for Information Security Magazine, SecurityPortal and SecurityFocus, and a contributor to nine books, including those in his Open Source Security Series and the "Stealing the Network" series. He has been invited to speak at and chair conferences around the world. His first talk at Def Con was in 2000. Jay is a founder and both the CTO and Chief Operating Officer of the information security consulting company InGuardians.

Serious Intro to Python for Admins
Davin Potts, Python Core Developer
Intended for an audience of IT managers and admins who are either responsible for systems with deployed Python apps and/or interested in the security implications of developing their own tools/scripts/apps in Python. This will be a hands-on exercise from start to finish designed to leave you with a sense of the mentality of Python and an ability to quickly look up what you need when expanding your knowledge of Python in the future. Prior programming experience not required. However it would be helpful if you've seen lots of Monty Python skits before.

We've been asked how to remove blank rows in Excel an absurd amount of times, so we decided to post it as it truly is a FAQ.
While there are a few ways, here is a super simple one that anyone should be able to follow.
Press the F5 Key to cause the "Go To Special" dialog box to pop up.
This will highlight all blanks in the sheet. From here, simply delete the rows that are selected.
1) Back everything up!!!
2) Download/Install needed software
- PuTTY or equivalent SSH client
3) Temporarily Enable SSH
- We don’t recommend leaving SSH on permanently. SSH can be temporarily enabled via the ESXi vSphere. Step-by-step instructions can be found at: http://www.thomasmaurer.ch/2011/08/enable-ssh-on-esxi-5-via-vsphere-client/
3) Put the ESXi system into maintenance mode
- Make sure you have all of your VM’s backed up somewhere else just in case. While we have never had any corruption during an upgrade, it’s always wise to have quality backups prior to an upgrade.
4) Follow the steps below
- SSH into your system.
- Enable the httpClient (Copy/Paste the following command into PuTTY)
esxcli network firewall ruleset set -e true -r httpClient
- Perform the upgrade (Copy/Paste the following command into PuTTY)
esxcli software profile update -p ESXi-6.5.0-4564106-standard -d https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml
- Disable the httpClient (Copy/Paste the following command into PuTTY)

The Black Art of Wireless Post-Exploitation: Bypassing Port-Based Access Controls Using Indirect Wireless Pivots
Gabriel Ryan, Security Engineer at Gotham Digital Science
Most forms of WPA2-EAP have been broken for nearly a decade. EAP-TTLS and EAP-PEAP have long been susceptible to evil twin attacks, yet most enterprise organizations still rely on these technologies to secure their wireless infrastructure. The reason for this is that the secure alternative, EAP-TLS, is notoriously arduous to implement. To compensate for the weak perimeter security provided by EAP-TTLS and EAP-PEAP, many organizations use port based NAC appliances to prevent attackers from pivoting further into the network after the wireless has been breached. This solution is thought to provide an acceptable balance between security and accessibility.
The problem with this approach is that it assumes that EAP is exclusively a perimeter defense mechanism. In a wireless network, EAP actually plays a subtle and far more important role. WPA2-EAP is the means through which the integrity of a wireless network's physical layer is protected. Port-based access control mechanisms rely on the assumption that the physical layer can be trusted. Just as NACs can be bypassed on a wired network if the attacker has physical access to the switch, they can also be bypassed in a wireless environment if the attacker can control the physical layer using rogue access point attacks.
In this presentation, we will apply this concept by presenting a novel type of rogue access point attack that can be used to bypass port-based access control mechanisms in wireless networks. In doing so, we will challenge the assumption that reactive approaches to wireless security are an acceptable alternative to strong physical layer protections such as WPA2-EAP using EAP-TLS.

While at OGSystems, he worked as a lead engineer on the Mosquito project, a geospatial intelligence tool that leverages wireless technology to track potential threats. Gabriel currently works for the international security consulting firm Gotham Digital Science at their New York office, where he performs full scope red team penetration tests for a diverse range of clients. He also contributes heavily to his company's research division, GDS Labs. Some of his most recent work includes a whitepaper on rogue access point detection, along with the popular tool Eaphammer, which is used for breaching WPA2-EAP networks. On the side, he serves as a member of the BSides Las Vegas senior staff, coordinating wireless security for the event. In his spare time, he enjoys live music, exploring the outdoors, and riding motorcycles.
Demystifying the OPM Breach: WTF Really Happened

Fooling the Hound: Deceiving Domain Admin Hunters
Tom Sela, Head of Security Research at illusive networks
The conflict between cyber attackers and defenders is too often in favor of attackers. Recent results of graph theory research incorporated into red-team tools such as BloodHound, shift the balance even more dramatically towards attackers Any regular domain user can map an entire network and extract the precise path of lateral movements needed to obtain domain admin credentials or a foothold at any other high-value asset. Knowing the precise path needed to reach a target decreases the chances of an attacker making mistakes and being detected, putting defenders at a very clear disadvantage.
One traditional defensive approach is to make the ability to map the network more difficult by restricting access to information. However, such restrictions cannot be applied to all platforms, and even if they could be, it is not a trivial task in production environments.
In this talk, we present a new practical defensive approach: deceive the attackers. Since the time of Sun Tzu, deceptions have been used on the battlefield to win wars. In recent years, the ancient military tactic of deceptions has been adopted by the cyber-security community in the form of HoneyTokens. Cyber deceptions, such as fictitious high-privilege credentials, are used as bait to lure the attackers into a trap where they can be detected.
To shift the odds back in favor of the defenders, the same BloodHound graphs that are generated by attackers should be used by defenders to determine where and how to place bait with maximum effectiveness. In this way, we ensure that any shortest path to a high-value asset will include at least one deceptive node or edge. Effectively designed and placed bait would make it very difficult for the attacker to avoid detection, shifting the odds back in favor of defenders.

Fortune 100 InfoSec on a State Government Budget
Eric Capuano, SOC Manager at Texas Department of Public Safety
A common misconception is that it takes spending millions to be good at security. Our security team at Texas Department of Public Safety has proved this to be untrue. We run a full-fledged Security Operations Center and leverage some very proactive controls and incident response techniques while spending a fraction of what similar agencies are allocated.
This talk outlines many of the thought processes and "tricks" to doing security well, without breaking the bank. Some concepts include thinking critically about ROIs of existing equipment, not buying into every "shiny box", not being afraid to explore open source options, and where to spend your money for the highest ROI (people!).
This is not the typical "Problem, problem, problem...." talk.... This is a solution-based talk where I'll share SOLUTIONS to very real-world scenarios facing SOC teams everywhere.

Go Beyond Tabletop Scenarios by Building an Incident Response Simulation Platform
Eric Capuano, SOC Manager at Texas Department of Public Safety
Ask yourself - how prepared is your incident response team for a worse case scenario event on your network? How well can your team function as a cohesive unit while executing fast and effective incident response in an "all hell breaking loose" situation? Even seasoned blue teams often lack the experience performing in these situations because they are (hopefully) far and few. Most organizations approach to this is "if we're breached, we'll just rely on our policies and procedures"....that is akin to paramedics learning first responder skills by reading healthcare magazines. Waiting for a crisis to happen before training for a crisis is a losing approach. Not to mention, it is often during a crisis that critical blind spots present themselves--too little too late. Tabletop scenarios are a great option as they require zero resources aside from conversation. However, referring to my previous example, first responders do not learn CPR by talking about it. For things that must become muscle memory, instinctive, you must simulate the event and go through the motions. That is exactly what I am doing with my team - and we're doing it with in-house resources and spare equipment. This talk is a deep-dive technical discussion on how we built a mockup enterprise network so that we could unleash hell on it in order to practice operating as a focused IR team. Some of the concepts will be familiar, but I do have a few clever tricks and tools to share that will significantly increase the "realism" of the exercises. I will also share a few of the red team scenarios that we have employed in past events. Best part -- almost all of this can be accomplished with open source tools and inexpensive equipment, but I'll also share tips and tricks on getting free commercial hardware and software for use in your new simulation environment!

How Hackers Changed The Security Industry
Chris Wysopal, CTO and Co-Founder of Veracode
Before hackers got involved in cybersecurity the industry was focused on products and compliance. Security was security features: firewalls, authentication, encryption. Little thought was given to vulnerabilities that allowed the bypassing of those features. Gene Stafford famously said SSL between two PCs is like using an armored car to deliver money from one park bench to another. Hackers came along with the idea that you use offensive techniques to simulate how an attacker would discover vulnerabilities in a networks, a system, or an application. Offensive skills have been on the rise ever since and now the best way to secure something it to try and break it yourself before the attacker does.
This history will be told from a member of the hacker group The L0pht who lived the arc from the underground, to consumer advocates, to speaking at the U.S. Senate, to forming a 200 employee security consultancy, to schooling Microsoft and changing how people build software.
Attendees will learn why we need the kind of tools hackers build to secure our systems and why we need people who are taught to think like hackers, 'security champions', to be part of software development teams.
Chris Wysopal (Twitter: @WeldPond) Chris Wysopal is currently Veracode's CTO and co-founder. He is one of the original vulnerability researchers and an early member of L0pht Heavy Industries, which he joined in 1992. He is the author of netcat for Windows and one of the authors of L0phtCrack. He has testified on Capitol Hill in the US on the subjects of government computer security and how vulnerabilities are discovered in software. He published his first advisory in 1996 on parameter tampering in Lotus Domino and has been trying to help people not repeat this type of mistake for 15 years.

Hunting Down the Domain Admin and Rob Your Network
Keith Lee, Senior Security Consultant at Trustwave SpiderLabs
Portia: it's a new tool we have written at SpiderLabs to aid in internal penetration testing test engagements. The tool allows you to supply a username and password that you have captured and cracked from Responder or other sources as well as an IP ranges, subnet or list of IP addresses. The tool finds its way around the network and attempts to gain access into the hosts, finds and dumps the passwords/hashes, resuses them to compromise other hosts in the network. In short, the tool helps with lateral movements in the network and automating privilege escalation as well as find sensitive data residing in the hosts.

At Cloudflare we deal with DDoS attacks every day. Over the years we've gained a lot of experience in defending from all different kinds of threats. We have found that the largest attacks that cause the internet infrastructure to burn are only possible due to IP spoofing.
In this talk we'll discuss what we learned about the L3 (Layer 3 OSI stack) IP spoofing. We'll explain why L3 attacks are even possible in today's internet and what direct and reflected L3 attacks look like. We'll describe our attempts to trace the IP spoofing and why attack attribution is so hard. Our architecture allows us to perform most attack mitigations in software. We'll explain a couple of effective L3 mitigation techniques we've developed to stop our servers burning.
While L3 attacks are a real danger to the internet, they don't need to be. With a bit of cooperation and couple of technical tricks maybe we can fix the IP spoofing problem for all.

Iron Sights for Your Data
Data breaches have become all too common. Major security incidents typically occur at least once a month. With the rise of both security incidents and full data breaches, blue teams are often left scrambling to put out fires and defend themselves without enough information. This is something that can be changed with the right tools. Tools now available allow blue teams to weaponize data and use it to their advantage. This talk reviews frameworks for clean, consistent data collection and provides an overview of how predictive analytics works, from data collection to data mining to predictive analytics to forecasts. The allows the blue team to focus on potential risks instead of trying to put out every fire.

Layer 8 and Why People are the Most Important Security Tool
Damon Small, Technical Director, Security Consulting at NCC Group North America
People are the cause of many security problems, but people are also the most effective resource for combating them. Technology is critical, but without trained professionals, it is ineffective. In the context two case studies, the presenter will describe specific instances where human creativity and skill overcame technical deficiencies. The presenter believes this topic to be particularly relevant for the Packet Hacking Village, as many techniques used are the same that are pertinent for Capture the Packet and Packet Detective.
Technical details will include the specific tools used, screenshots of captured data, and analysis of the malware and the malicious user's activity. The goal of the presentation is show the importance of technical ability and critical thinking, and to demonstrate that skilled people are the most important tool in an information security program.

Past, Present and Future of High Speed Packet Filtering on Linux
Gilberto Bertin, CLoudflare
As internet DDoS attacks get bigger and more elaborate, the importance of high performance network traffic filtering increases. Attacks of hundreds of millions of packets per second are now commonplace. Unfortunately line rate filtering is still an open problem.
In this session we will introduce modern techniques for high speed network packet filtering on Linux. We will follow the evolution of the subject, starting with Iptables and userspace offload solutions (such as EF_VI and Netmap), discussing their use cases and their limitations. We will then move on to a new technology recently introduced in the Linux kernel called XDP (express data path), which works by hooking an eBPF program into the lowest possible layer in the Linux kernel network stack, allowing network traffic to be filtered at high speeds. We will discuss the strengths of this solution, show some sample XDP programs and give operational tips.
