AWS Persistence and Lateral Movement Techniques

Peter Ewane, Security Researcher at AlienVault

Presentation Slides: phv2017-pewane.pdf

The use of Amazon Cloud as a base of operations for businesses is increasing at a rapid rate. Everyone from 2 person start-ups to major companies have been migrating to the cloud. Because of this migration, cloud vendors have become the focus of potential exploitation and various role abuse in order to achieve persistence. This presentation will cover several different methods of post-infection and account persistence along with a discussion on best practices that can be used to protect from such techniques.

Peter Ewane (Twitter: @eaterofpumpkin) is a security researcher, sometimes conference speaker and a mostly blue teamer for the Alien Vault Labs Team. When not playing with computers, Peter enjoys trying and making interesting cocktails and collecting whisk(e)y.

The Black Art of Wireless Post-Exploitation: Bypassing Port-Based Access Controls Using Indirect Wireless Pivots

Gabriel Ryan, Security Engineer at Gotham Digital Science

Presentation Slides: phv2017-gryan.pdf

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 this presentation, we will present 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.

Gabriel Ryan (Twitter: @s0lst1c3) is a penetration tester and researcher with a passion for wireless and infrastructure testing. His career began as a systems programmer at Rutgers University, where he assessed, diagnosed, and resolved system and application issues for a user community of over 70,000 faculty, students, and staff.

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.

Fooling the Hound: Deceiving Domain Admin Hunters

Tom Sela, Head of Security Research at illusive networks

Presentation Slides: phv2017-tsela.pdf

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. 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.

Tom Sela (Twitter: @4x6hw) is Head of Security Research at illusive networks, specializing in Reverse Engineering, Malware Research, and OS internals. Prior to joining illusive, Tom lead the Malware Research team at Trusteer (acquired by IBM).

Fortune 100 InfoSec on a State Government Budget

Eric Capuano, SOC Manager at Texas Department of Public Safety

Presentation Slides: phv2017-ecapuano.pdf

A common misconception is that it takes spending millions to be good at security. Not only is this untrue, but I will share ways that you can increase security posture while actually reducing spending. This talk outlines many of the tricks and mindsets to doing security well without breaking the bank. This is not the typical “Problem, problem, problem....” talk.... This is a solution-based talk that goes back to many of the basic challenges facing SOC teams everywhere.

Eric Capuano (Twitter: @eric_capuano) is an Information Security professional serving state and federal government as well as SMBs, start-ups and non-profits. Also, a member of the Packet Hacking Village team at DEF CON.

Go Beyond Tabletop Scenarios by Building an Incident Response Simulation Platform

Eric Capuano, SOC Manager at Texas Department of Public Safety

How prepared is your incident response team for a worst case scenario? Waiting for a crisis to happen before training for a crisis is a losing approach. For things that must become muscle memory, instinctive, you must simulate the event and go through the motions. This talk is a deep-dive technical discussion on how you can build your own DFIR simulation. 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

Presentation Slides: phv2017-cwysopal.pdf

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. 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 is also the author of "The Art of Software Security Testing" published by Addison-Wesley.

Hunting Down the Domain Admin and Rob Your Network

Keith Lee, Senior Security Consultant at Trustwave SpiderLabs
Michael Gianarakis, Director of Trustwave SpiderLabs Asia-Pacific

Presentation Slides: phv2017-leegianarakis.pdf

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, reuses 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.

Keith Lee (Twitter: @keith55) is a Senior Security Consultant with Trustwave's SpidersLabs Asia-Pacific.

IP Spoofing

Marek Majkowski, Cloudflare

Presentation Slides: phv2017-mmajkowski.pdf

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.

Marek Majkowski (Twitter: @majek04). After fruitful encounters with such diverse topics as high performance key value databases, distributed queueing systems, making real time web communication enjoyable, and accelerating the time so that testing servers and protocols takes seconds, Marek Majkowski finally settled for working on DDoS mitigation in the CloudFlare London office, where he appreciates most the parking space for his motorbike.

Iron Sights for Your Data

Leah Figueroa

Presentation Slides: phv2017-leah.pdf

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

Presentation Slides: phv2017-chef.pdf

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.

Passwords on a Phone

Sam Bowne

Presentation Slides: phv2017-sbowne.pdf

Almost all Android apps from major retailers store your password on the phone, which is dangerous and unnecessary. And they don't even use the Android KeyStore; they just use custom encryption schemes that generate a key in predictable ways, so passwords are easily recoverable. This is “fake encryption” – the data appears to be encrypted but in fact is not actually protected from attackers. I will present results of my tests of many top retailers, and demonstrate how to steal passwords from them. I will also list a few (very few) companies who actually protect their customers' passwords properly.

Past, Present and Future of High Speed Packet Filtering on Linux

Gilberto Bertin, CLoudflare

Presentation Slides: phv2017-gbertin.pdf

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. 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.

Gilberto Bertin (Twitter: @akajibi) originally from a little Italian town near Venice, loves tinkering with low level systems, especially networking code. After working on variety of technologies like P2P VPNs and userspace TCP/IP stacks, he decided to move to London to help the Cloudflare DDoS team filter all the bad internet traffic.

Stories from a 15 days SMB Honeypot: Mum, Tons of WannaCry and Evils Attacked Our Home!

Tan Kean Siong, Security Researcher

Presentation Slides: phv2017-tksiong.pdf

WannaCry, Eternal Blue, SambaCry are the popular topic recently. During the outbreak in May 2017, we designed a 'real' Windows 7 / Samba server with the open source Dionaea honeypot and exposed the favourable SMB port to the world. There are tons of expected WannaCry attacked the pot, and interestingly there are more juicy collection than that! In this session, we would like to present the stories from a 15 days SMB honeypot. As a honeypot hobbyist, we deployed an emulated Windows 7 machine which implanted with DoublePulsar backdoor. Yes, a Windows system infected with DoublePulsar! Also, our honeypot is up for the CVE 2017-7494 SambaCry vulnerability. We observed tons of scanning which looks for targets to spread the expected WannaCry ransomware. Surprisingly, there are more juicy collection in the pot, e.g. EternalRocks, Reverse Shell, RAT, DDoSers, Coin Miner, Trojan, etc (you name it you have it!). We love to share various interesting data, with the 15 days observation from a single home-based sensor in the entire IP space.

Strengthen Your SecOps Team by Leveraging Neurodiversity

Megan Roddie, Cyber Security Analyst at the Texas Department of Public Safety

Presentation Slides: phv2017-mroddie.pdf

High productivity, extreme attention to detail, logical/calculated, passionate, and hyper-focused. These are all characteristics considered valuable in the information security industry. However, a certain group of people who exceed expectations in these skill sets are constantly overlooked for job positions. That group of people is the High Functioning Autistic (HFA) community. Individuals in the high functioning autistic community are often overlooked for job positions due to their social disabilities which makes them perform poorly in an interview and in their interactions with other people. However, if you look past their awkward behavior and social struggles, you will find these individuals are perfectly suited for roles in the information security industry. This talk aims to show the listeners that, as many tech companies have found, the HFA community is ripe with individuals who could be the best of the best in the security industry if given the chance. The audience will realize that a small investment in time, understanding, and acceptance can result in the addition of an invaluable member to a Security Operations team.

Megan Roddie (Twitter: @megan_roddie) is a graduate student pursuing her Master's in Digital Forensics at Sam Houston State University while also working as a Cyber Security Analyst at the Texas Department of Public Safety.

Threat Intel for All: There's More to Your Data Than Meets the Eye

Cheryl Biswas

Presentation Slides: phv2017-cbiswas.pdf

Threat Intel isn't just a buzzword. It's about what you do with your data, to take a more proactive stance at securing yourself. Everybody has data, but we don't realize how to harness the power, to operationalize the context and relevancy within it as our strategic advantage. That's why Threat Intel isn't some shiny expensive box only the big kids get to play with. More importantly, as the nature of threats evolve, we need to keep pace by doing more than just monitoring. Everyone can level up by looking beyond their logs to see what's really in their data. Because there are all kinds of people in your neighbourhood...

As humans, we have had 60,000 years to perfect communication, but those of us working in IT, regardless of which side (Blue or Red Team), still struggle with this challenge. We have done our best over the centuries to yell "FIRE!" in a manner befitting our surroundings, yet today we seem utterly incapable of providing that very basic communication capability inside organizations. This talk will endeavor to explain HOW we can yell "FIRE!" and other necessary things across the enterprise in a language both leadership, managers and end-users understand.
