UAC 0day, all day!
This workshop is available to attendees of all levels, however, a basic familiarity with Process Monitor and the Windows API are recommended. The workshop will provide the required knowledge to find, analyze and exploit process workflows which allow an attacker to elevate their privileges from Medium to High integrity. The workshop is divided into the following sections.
- Identifying auto-elevating processes
- Analyzing process workflows
- Finding UAC bypass targets
Auto-Elevation>Elevated File Operations:
- Using the IFileOperation COM object
- Tricking the Process Status API (PSAPI)
Auto-Elevation>Getting UAC 0day (Pre Windows RS2):
- Analysis of known UAC bypasses
- Understanding the Windows Side-By-Side Assembly
- Creating proxy DLL's
- Using the Bypass-UAC framework (https://github.com/FuzzySecurity/PowerShell-Suite/tree/master/Bypass-UAC)
- Dropping 0day(s)!
Auto-Elevation>Triaging Windows RS2:
- Environment variables
- Registry abuse
- COM objects
- Process tokens
The workshop has intense hands-on labs where attendees will put the theory into practice. After attending, you will immediately be able to apply this knowledge in the field. The next time someone tells you the default UAC settings are sufficient you will be able to set them straight!
My name is Ruben Boonen (@FuzzySec), I have been working in InfoSec since 2012. I have a well-rounded skill set, having taken on many application, infrastructure and bespoke engagements. I have however developed a special interest for Windows: Domain hacking, exploit development, client-side attacks, restricted environments, privilege escalation, persistence, post-exploitation and PowerShell!
I love breaking stuff but it is equally important to me to share that knowledge with the wider community. I have previously been a trainer at Black Hat, Def Con and various BSides events in the UK. Additionally, I maintain a InfoSec blog (http://www.fuzzysecurity.com/) where I publish research on a variety of topics!

Practical Malware Analysis: Hands-On
Learn how to analyze Windows malware samples, with a hands-on series
of projects in a fun, CTF-style environment. There are four levels of
- 1. Basic static analysis with file, strings, PEiD, PEview, Dependency
Walker, and VirusTotal
- 2. Basic dynamic analysis with Process Monitor, Process Explorer,
RegShot, and Wireshark
- 3. Advanced static analysis with IDA Pro Free and Hopper
- 4. Advanced dynamic analysis with Ollydbg and Windbg
The first challenges are easy enough for beginners, and the later ones get difficult enough to interest intermediate security professionals. We will demonstrate the challenges, discuss the technologies and techniques, and help participants get through them as needed.
These challenges use harmless malware samples from the "Practice Malware Analysis" book by Michael Sikorski and Andrew Honig.
All materials and challenges are freely available at samsclass.info, including slide decks, video lectures, and hands-on project instructions. They will remain available after the workshop ends.

Decentralized Hacker Net
As hackers, sometimes we need to send data without anybody knowing anything. We don't want anybody to know what we're sending, so we use encryption. That's the easy part. We also don't want anybody to know that we're sending any data. That's the hard part. The observation of our presence on the network could be enough to get us in trouble. And that's just not acceptable. We need to figure out a way to hide in plain sight.
Creating an environment where data can be sent securely and our presence on the network is hidden, is not an easy thing to do. We can't rely on centralized technologies, which means we need to build a decentralized network. The network should be adaptive and flexible enough to send any type of data to any number of users. But how do we inject anonymity into a network while still supporting the verification of identity between parties? Can we establish trust without having to trust?
This workshop takes you through the process of creating a decentralized network that allows you to circumvent detection by governments and corporations. You'll be able to securely communicate and share data while masking your online identity. You'll create an adaptive, node-based infrastructure where data is shared via Distributed Hash Tables (DHT) backed by real-time asymmetric Elliptic-curve cryptography (ECC). If you've ever wanted to punch a hole through a great (or not-so-great) firewall, this workshop is for you.
Please note that this is a medium-level, technical workshop and requires that attendees have prior experience in at least one programming language, preferably C or C++. Bring your laptop, a USB flash drive, and your favorite C/C++ 11 compiler (>= gcc/g++ 4.9.2 or msvc 2015).

Scanning the Airwaves: building a simple radio scanning system using SDR
Every second of every day, radio communications are flying through the air: shortwave radio, broadcast AM, FM and television, ham radio users. Taxi drivers, buses, parents using small toy radios to keep in touch in amusement parks. Have you ever wondered what's being said over the air? Many of these systems are easily listenable with some basic software and very inexpensive hardware dongles originally designed for capturing over-the-air television broadcasts. This workshop will walk you through the basics of radio systems, how they work, and how you can set up a listening post to decode these systems and listen in. We'll also cover the legalities of listening in, and where to find information online about popular frequencies to listen in on. If you have an SDR stick, please bring one. A number of sticks will be available to borrow for those without.

Hands-On Exploit Development
This course will provide a hands-on foundation in discovering and exploiting memory corruption issues. Complex memory corruption issues are discovered in software by security researchers regularly, resulting in bug bounties and exploit sales. In this workshop we will discuss how memory corruption works and gain some experience using the tools of the trade for developing working exploits such as GDB, Immunity Debugger, and Mona.py. Participants will exploit beginner friendly examples of common memory corruption issues allowing students to get familiar with how memory corruption works without getting stuck behind all the latest and greatest anti-exploitation methods. Both Windows and Linux examples will be included. Students will be provided with target virtual machines with vulnerable software running as well as additional exercises for continued practice after class. By popular demand this course has moved to more modern operating systems, though the bugs used are still beginner friendly. Exploits will be written in the Python programming language but exploit skeletons will be provided for those unfamiliar with the language. This workshop prepares students for future study in vulnerability discovery and exploits development.
