First Batch of Accepted Packet Hacking Village Talks at DEF CON 29 Announced

Schedules of talks and events at the Packet Hacking Village are available at More talks will be added soon. All talks will be streamed on YouTube, Twitch, Facebook, and Periscope.

*nix Processes. Starting, Stopping, and Everything In Between

Nick Roy

Core Topic: Operating Systems: *nix

Recording discusses Linux and Unix processes, starting with a high level overview of what a process is and what the key components are. We then take a look at how the operating system manages multiple processes, what are the main components of a running process, and finally some common syscalls used in Linux when creating processes. Finally, we look at a few code samples to show how these calls are used with a simple shell. All code can be found here to compliment the video:

Linux Binary Analysis w/ Strace

Jared Stroud, Lacework

Core Topic: File Analysis

The strace utility allows for deep insight into what an application is doing on a nix host. While the amount of data produced can be overwhelming, in this video I'll demonstrate how to filter, log and obtain relevant information for a wide variety of use cases around file analysis. From diagnosing a bisheaving application, to revealing a malware's secrets. This video will give a practical introduction in using strace to spy on *nix applications at the syscall level. All resources can be found here:

MITRE Engage: A Framework for Adversary Engagement Operations

Stan Bar, Capability Area Lead, Cyber Denial, Deception, and Adversary Engagement, The MITRE Corporation
Gabby Raymond, Co-Capability Area Lead, Cyber Denial, Deception, and Adversary Engagement, The MITRE Corporation
Maretta Morovitz, Senior Cyber Security Engineer, The MITRE Corporation

Core Topic: File/Network Monitoring

For 10+ years MITRE has been engaged in denial, deception, and adversary engagement operations for internal defense and research purposes. We have created MITRE Engage as a framework for planning and communicating about adversary engagement operations. In our talk we include:

  • A brief overview of what we mean when we say denial, deception, and adversary engagement
  • Our vision for the future and why we think this technology matters
  • A brief history of our past experiences (and failures) in this space and how that shaped where we are today
  • The official release of MITRE Engage 0.9 Beta and ask for community feedback
  • A fictional walkthrough of how you can use Engage to get started in adversary engagement operations

She was recently named as one fo the AFCEA 40 Under 40 Awardees for 2021. Outside of work you can find her nerding out about the latest Brandon Sanderson novel, still anxiously awaiting her letter from Hogwarts, or snuggling with her dog and hedgehog.

RCE via Meow Variant along with an Example 0day

Özkan Mustafa AKKUŞ, Senior Cyber Security Consultant and Vulnerability Researcher at Turk Telekom

Core Topic: Operating Systems: *nix

I will touch Some Alternative Bypass Restriction Techniques. Then I will present a vulnerability of Ericsson Network Location that provides the infrastructure of the research and we are going to touch on the meow variant with details through this vulnerability Towards the end we are going to prepare a Metasploit module and exploit the vulnerability.

Ozkan (Twitter: @ehakkus) is a vulnerability researcher and senior cyber security consultant in Turkey. Ozkan publishes security vulnerabilities on international platforms that he has discovered. He shares his experiences and works on his personal blog ( He gave training and presentations in many universities and institutions in his country. In addition to these studies, He gave the presentation of "The Vulnerability That Gmail Overlooked and Enabling Threat Hunting" in Packet Hacking Village at DEF CON 28 and "0day Hunting and RCE Exploitation in Web Applications" in AppSec Village at DEF CON 27.

Seeing the Forest Through the Trees – Foundations of Event Log Analysis

Jake Williams, CTO of BreachQuest

Core Topic: System Forensics

During an incident, everyone knows you need to review the logs – but what are they actually telling you? There's a wealth of information to be had in your logs event logs, but most analysts miss the forest because they don't understand the trees. In this talk, Jake will walk you through some of the most impactful event logs to focus on in your analysis. We'll target some old favorites covering login events, service creation, and process execution. We'll also examine task scheduler logs, useful in uncovering lateral movement and privilege escalation. Finally, we'll discuss some of the new event logs available in Windows 10 (if only you enable them first). If you don't want to be barking up the wrong tree during your next insider investigation or getting axed because you failed to identify the lateral movement attempts, make sure to watch this video.

Jake Williams (Twitter: @malwarejake) is an incident responder, red teamer, occasional vCISO, and prolific infosec shitposter. He has traveled the world, but isn't welcome in China or Russia (and avoids most countries they have extradition treaties with). When not speaking at a conference like this one, it's a good bet that Jake is engaged in hand to hand combat with an adversary rooted deep in a network or engineering ways to keep them out. Jake's career in infosec started in the intelligence community, but has taken around the world securing networks of all shapes and sizes, from utilities to hospitals to manufacturing plants.

The War for Control of DNS Encryption

Dr. Paul Vixie, Chairman and CEO and Cofounder of Farsight Security, Inc.

Core Topic: Core Networking

Pervasive monitoring of the Internet by both government, corporate, and criminal actors has triggered an encryption wavefront as wide as the Internet itself. DNS, as the map of the Internet's territory, is seen as especially sensitive and there are now several competing encryption standards waiting to be deployed. In this short talk, Dr. Vixie will explain the original problem, describe the protocol-level solutions, and then show how vendors like Google, Mozilla Corporation, Microsoft, and Apple are deploying these technologies across their product lines. Opinions may also be offered.

Dr. Paul Vixie (Twitter: @PaulVixie) is an Internet pioneer. Currently, he is the Chairman, Chief Executive Officer and Cofounder of Farsight Security, Inc. He was inducted into the Internet Hall of Fame in 2014 for work related to DNS and DNSSEC. Dr. Vixie is a prolific author of open-source Internet software including BIND, and of many Internet standards documents concerning DNS and DNSSEC. In addition, he founded the first anti-spam company (MAPS, 1996), the first non-profit Internet infrastructure software company (ISC, 1994), and the first neutral and commercial Internet exchange (PAIX, 1991). He earned his Ph.D. from Keio University.
