TLDR; Nifty Python tool to play music corresponding to network traffic that contains the potential for an accessibility function for the visually-impaired.
Originally conceived of as a cool idea to examine network traffic generated by penetration testing in lieu of reviewing tcpdump or Wireshark output, [email protected]@quet turned into a valid means of creating music from network traffic patterns. Also, by creating a sound-based representation of network traffic, the utility provides insight into normal traffic patterns as opposed to oddities such as ICMP ping or UDP/TCP port scans. Anyone, whether an analyst or tester, interested in keeping track of the network can listen to the sounds of the packets instead of scrolling through Wireshark or tcpdump packets.
As an example, if a port scan was observed by the monitoring interface, those packets would correspond to different sounds, thereby yielding an aural experience matching that traffic pattern. Visually-impaired individuals could be trained as to the notes and corresponding packets and be empowered to conduct hitherto inaccessible network analysis. The project consists of a Python script to demonstrate both live traffic examples and previously recorded packet captures.

This talk will provide a quick overview honeypots, an explanation of the cyber deception space, and the benefits of implementing deception as part of your cyber defense program. In addition, this talk will highlight the HoneyDB project, which enables anyone to get started with operating deception sensors and start collecting threat information. Finally, this presentation will describe how I built scalable honeypot sensor collection, employing a "Frankenstein Cloud Architecture", for minimal cost.
Note, I did present (30 mins) last year, however this talk will contain new material, and will provide an update on the projects I presented last year. A summary of how things have gone, and where they are going. I received a great response from last year’s talk, so I hope to keep the community talking, learning, and involved in the topics/projects on honeypots & cyber deception.

Without exploit mitigations and with an insecure-by-default design, writing malware for FreeBSD is a fun task, taking us back to 1999-era Linux exploit authorship. Several members of FreeBSD's development team have claimed that Capsicum, a capabilities/sandboxing framework, prevents exploitation of applications. Our in-depth analysis of the topics below will show that in order to be effective, applying Capsicum to existing complex codebases lends itself to wrapper-style sandboxing. Wrapper-style sandbox is a technique whereby privileged operations get wrapped and passed to a segregated process, which performs the operation on behalf of the capsicumized process. With a new libhijack payload, we will demonstrate that wrapper-style sandboxing requires ASLR and CFI for effectiveness. FreeBSD supports neither ASLR nor CFI. Tying into the wrapper-style Capsicum defeat, we'll talk about advances being made with libhijack, a tool announced at Thotcon 0x4. The payload developed in the Capsicum discussion will be used with libhijack, thus making it easy to extend. We will also learn the Mandatory Access Control (MAC) framework in FreeBSD. The MAC framework places hooks into several key places in the kernel. We'll learn how to abuse the MAC framework for writing efficient rootkits. Attendees of this presentation should walk away with the knowledge to skillfully and artfully write offensive code targeting both the FreeBSD userland and the kernel.

This talk will discuss the benefits of data visualization when performing security analysis and also presenting analysis findings. Too often information security analysts try to solve complex security problems by looking at the output of a .txt document. Even worse they present their findings with the same dull output they used for analysis. The security community need to take some direction from the infographic age and display data in way their clients can easily digest. During this talk I will talk about a variety of techniques one could use to help identify malicious patterns in data sets and how to present them by visualizing the data in graphs like:
Time Series / Timelines
These visualizations (if used correctly) can serve as a tool for information security analysts to detect and present findings that show the threat.

The talk that lives up to its name! Completely self-centered on how to work with your bait and tackle to jerk off the line of stories in your head and get back to reality. Avoid phishing by not falling for the hookers! Even yourself! Social engineering! Deep penetrating psychology mixed with blatant innuendo and enough buzzwords to make a CISO throw BitCoin at it...then make engineers figure out a POC for what this Purple Team Darknet vaporware actually does!
Techniques on how to observe and handle your own bait and tackle to avoid biting someone else’s hook. We get hooked in that moment of tightening when we reach for relief. To get unhooked, we begin by recognizing that moment of unease and learn to relax in that moment. Observe yourself to avoid the hooks. Discover your motivations and attachments so you can recognize them in that moment. Learn to work with yourself to relax so you can change how you react to bait and get unhooked when you eventually bite the hook. Don’t fall for hookers, become a master baiter!

Still trying to make sense of deserialization flaws and how they became a "thing"? Deserialization flaws can be very complex and require deep knowledge of the target programming language, so it is no surprise that most hackers don't understand much beyond use of payload tools (e.g. ysoserial). Unlike most talks on this subject, Jason will break down the jargon to explain which elements of Object Oriented Methodologies (OOM) have brought on a plethora of deserialization flaws in Java and other OO languages. This talk will be accompanied with simplified demos and sample code to help understand deserialization flaws and how corresponding attack payloads are made.

Artificial Neural Networks are a fascinating computational approach modeled to react similar to a biological brain to solve problems. Neural networks are a very powerful tool that enable machines to teach and evolve themselves. You can utilize this power in almost any application. Don't be intimidated by the equations and Greek symbols of this cutting-edge technology, I will guide you on how to slay this technology and make it bend to your will!
In this session, we are going to demystify the presumed complexity of Neural Networks. No need for a PhD or mathematical background, after this overview, you will be discussing these concepts around the water cooler. There will be very little math and lots of coding. The goal is for everyone to become acquainted with Neural Network from a pragmatic standpoint. In this session, we will take a closer look at artificial neural networks inspired by biological neurons. We will study how these neurons can be modeled in a digital counterpart. After a short introduction of the actor model, the commonalities between neurons and how Actors work by building an asynchronous and reactive neural network will be demonstrated.
Just when you think it couldn't get any better, I will show you how to employ the functional paradigm to leverage multicore machines and GPUs to make your neural network predictions infinitely faster through parallelism. By the end of this talk, you will learn the basic concepts of Neural Network and how to apply functional concurrency to estimate future stock prices at smoking fast speeds…and perhaps get rich while practicing!

HideNSneak evolved as a tool to expand evasive penetration testing capabilities. It allows users to rapidly deploy, manage, and quickly take down a distributed cloud attack infrastructure by leveraging features of large Cloud Providers and their content delivery networks. Techniques include domain fronting with multiple providers, distributed scanning, and source of attack obfuscation. Leaning on the reputation of these networks allows traffic to more easily blend in to network traffic and create difficulty in blocking attack infrastructure. Furthermore, the ephemeral nature of the tool itself provides a realistic threat simulation, which also simulates the realistic headache this type of attack causes defenders, when they try to attribute actions to certain sets of hosts.
The overview of the toolsets features will contain an explanation of the tactics and techniques in order to provide both red teamers and blue teamers alike with more insight into why this works in "modern" networks, as well as real world scenarios. Finally, information will be provided to blue teamers in an effort to provide knowledge that can be brought back and leveraged to increase security posture.
Mike Hodges is a Senior Security Consultant for the Optiv Attack and Penetration Practice.
