Call for Hands-On Workshops at Packet Hacking Village at DEF CON 28 Now Open


The Wall of Sheep would like to announce a call for Workshops at DEF CON 28 in Las Vegas, NV from Thursday, August 6th to Sunday, August 9th. The Packet Hacking Village Workshop's goal is to deliver hands-on training sessions that increase security awareness and provide skills that can be immediately applied after the conference. Our audience ranges from those who are new to security to the most seasoned practitioners in the security industry. Introductory workshops are welcome! A very nominal fee will be charged for advanced registration of these workshops. However, all proceeds will go directly to Hackers for Charity. This is your chance to give back to the community in multiple ways!

The hands-on workshops area will have 40 computers pre-loaded with the necessary tools so attendees will not need to bring their own laptop. There will be one computer available for the presenter that is a mirror of the attendees. The mirror laptop will be displayed on one screen; a second projected display and hookups is available for you to present your material. We will be able to pre-load any software (within reason) including one virtual machine for your presentation. The computers will boot Kali Linux. While network access is available to all machines, it should not be relied upon for your presentation... this is DEF CON after all. :)

Topics of interest include:

  • Tools for Network sniffing, intrusion detection, monitoring, reverse engineering, forensics, penetration testing, data collection and visualization
  • Purple teaming
  • Secure Software Development
  • Training in hacking/security tools and their usage in the corporate world
  • Programming for security practitioners
  • Tool/task automation and optimization
  • Incident response process and procedures

The Wall of Sheep will not accept product or vendor related pitches. If your content is a thinly-veiled advertisement for a product or service your company is offering, please do not apply!

The Call for Workshops will close on Friday, June 12th at 11:59 PM PDT. The list of talks will be finalized and published on Friday, June 26th.

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.

Ryan Kovar fought in the cyberwars and has been doing cybery things for almost 20 years. Now he is a Principal Security Strategist at Splunk building cool stuff, talking about security thingies, and helping other people fight their battles. He hates printers.

John Stoner is a Principal Security Strategist at Splunk. During his career he has worked in operations, consulting and solutions engineering. In his current role, he leverages his many years of experience in log management, SIEM, security operations and threat intelligence to provide solutions that drive greater situational awareness for organizations.

Reverse Engineering Malware 101

This workshop provides the fundamentals of reversing engineering (RE) Windows malware using a hands-on experience with RE tools and techniques. Attendees will be introduced to RE terms and processes, followed by basic x86 assembly, and reviewing RE tools and malware techniques. It will conclude by attendees performing a hands-on malware analysis that consists of Triage, Static, and Dynamic analysis.
 Prerequisites: Basic understanding of programming C/C++, Python, or Java
. Provided: A virtual machine and tools will be provided.
 Features: 5 Sections in 1.5 hours:

  • ~15 min Fundamentals
  • ~15 min Tools/Techniques

Serious Intro to Python for Admins

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.

Davin Potts is a Python Core Developer and lead dev for the multiprocessing module in the Python standard library. For a day job, Davin is a scientific software consultant working primarily on data science projects. Also refer to

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 Dawes 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.

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.

Johnny Long spent his career as a professional hacker. He is the author of numerous security books including No-Tech Hacking and Google Hacking for Penetration Testers and is a contributor to Kali Linux Revealed. He is the founder of Hackers for Charity and currently works with the Offensive Security team.

Intense Introduction to Modern Web Application Hacking

This course starts with an introduction to modern web applications and immediately starts diving directly into the mapping and discovery phase of testing. In this course, you will learn new methodologies used and adopted by many penetration testers and ethical hackers. This is a hands-on training where will use various open source tools and learn how to exploit SQL injection, command injection, cross-site scripting (XSS), XML External Entity (XXE), and cross-site request forgery (CSRF). We will wrap up our two hour fast-paced course by unleashing students on a vulnerable web application with their newly found skills.
