Slides:

Vulnerability disclosure, cloudy clouds, and million dollar shopping trips. This industry sucks. And is awesome. Our beloved security industry is a complicated beast. Companies are collaborating with researchers more now than they have ever, but it’s still easy to walk away feeling frustrated by an encounter with an otherwise seemingly responsive vendor. Microsoft’s Technical Fellow Jeffrey Snover and Security Architect Lee Holmes share their unique perspectives on this relationship and shed some light the corporate behaviors that might otherwise feel out of touch, and share their perspectives on getting on a solid path to more secure systems. This collaboration is making the world a safer place, however, and we now find ourselves at the cusp of another major industry shift. What does security look like in a world that’s becoming increasingly cloud-connected? With the vast majority of cloud capacity coming from two companies in Seattle, what chance do you possibly have to keep yourself secure? In addition to the torrid pace of change in our industry, there’s still a lot of regular ol’ security going on. New threats, new exploits, an ever changing attack surface. How do you keep YOUR companies secure in a world like this? It’s tempting to throw your hands up, get a money order for a million dollars, and just go shopping at RSA. That may eventually be part of the solution but it rarely the most effective path forward. So what is? Jeffrey Snover is a Technical Fellow and the Lead Architect for the Enterprise Cloud Group, covering Windows Server, Azure Stack, System Center, and Operations Management Suite. Snover is the inventor of Windows PowerShell, an object-based distributed automation engine, scripting language, and command line shell. Lee Holmes is the lead security architect of Microsoft’s Enterprise Cloud Group, covering Windows Server, Azure Stack, System Center, and Operations Management Suite. He is author of the Windows PowerShell Cookbook, and an original member of the PowerShell development team.

Daniel Bohannon – Invoke-Obfuscation: PowerShell obFUsk8tion Techniques & How To (Try To) D””e`Tec`T ‘Th’+’em’

Invoke-Obfuscation: PowerShell obFUsk8tion Techniques & How To (Try To) D””e`Tec`T ‘Th’+’em’ Daniel Bohannon – @danielhbohannon The very best attackers hide their commands from A/V and application whitelisting technologies using encoded commands and memory-only payloads to evade detection. These techniques thwart Blue Teams from determining what was executed on a target system. However, network defenders are catching on, and state-of-the-art detection tools now monitor the command line arguments for powershell.exe either in real-time or from event logs. We need new avenues to remain stealthy in a target environment. So, this talk will highlight a dozen never-before-seen techniques for obfuscating PowerShell command line arguments. As an incident responder at Mandiant, I have seen attackers use a handful of these methods to evade basic command line detection mechanisms. I will share these techniques already being used in the wild so you can understand the value each technique provides the attacker. Next, I will introduce three new layers of obfuscation that can be applied to any PowerShell command. You can use each layer independently, or stack them together to prevent any one technique becoming an easy signature for defenders. The first layer directly manipulates PowerShell and .Net cmdlets, functions and arguments. The second string manipulation layer can then be applied to a single command or an entire script. Finally, I will demonstrate several techniques for content execution using PowerShell command input parameters that hide command line arguments from appearing for powershell.exe. Attempting to detect every possible obfuscated version of particular commands is not an efficient means of detection. Updated PowerShell event logging mitigates many of the detection challenges that obfuscation introduces. However, many organizations do not enable this PowerShell logging and rely primarily on command line logging. Therefore, I will provide techniques that the Blue Team can use to detect the presence of these obfuscation methods in command line arguments. I will also highlight methods using C# within powershell.exe that enable the attacker to execute .Net functions without being recorded in PowerShell event logs. Attackers and popular frameworks like Metasploit, PowerSploit, and Empire use PowerShell’s remote download cradle to execute remote scripts on a target system entirely in memory. This capability is typically used to avoid A/V and many application whitelisting products. I will give particular focus to the numerous ways within PowerShell, .Net, and native Windows applications that this remote download functionality can be accomplished without using .Net’s popular Net.WebClient class. I will also explore a half dozen functions that attackers can use to encode and decode PowerShell commands, including .Net’s SecureString functions. I will conclude this talk by highlighting the public release of Invoke-Obfuscation.ps1. This tool applies the aforementioned obfuscation techniques to user-provided commands and scripts to evade command line argument detection mechanisms. These techniques are available as miniature plug-n-play versions to be easily added to existing PowerShell frameworks in an effort to promote more wide-scale adoption.

Last year, Joshua disclosed multiple vulnerabilities in Android’s multimedia processing library libstagefright. This disclosure went viral under the moniker “Stagefright,” garnered national press, and ultimately helped spur widespread change throughout the mobile ecosystem. Since initial disclosure, a multitude of additional vulnerabilities have been disclosed affecting the library.
In the course of his research, Joshua developed and shared multiple exploits for the issues he disclosed with Google. In response to Joshua and others’ findings, the Android Security Team made many security improvements. Some changes went effective immediately, some later, and others still are set to ship with the next version of Android—Nougat.
Joshua will discuss the culmination of knowledge gained from the body of research that made these exploits possible despite exploit mitigations present in Android. He will divulge details of how his latest exploit, a Metasploit module for CVE-2015-3864, works and explore remaining challenges that leave the Android operating system vulnerable to attack.  Joshua will release the Metasploit module to the public at DerbyCon

“Nose Breathing 101: A Guide to Infosec Interviewing” – Wartortell and Aaron Bayles

Video: https://www.youtube.com/watch?v=Y_5-4uSNHPw
Slides:

The Information Security sector is a special place filled with special snowflakes. For a special snowflake, interviewing for a job can sometimes be a daunting or awkward task. There is a thin line when talking to humans between looking cocky and potato. On the other side, the interviewer must understand that there’s a limited pool of special snowflakes. There’s a sweet spot between auto-hiring someone and telling them you’ll need three months to make a decision. Each snowflake must be nurtured into a beautiful snowerfly, or whatever their final form may be. For this talk I plan to start a conversation about how to interview and be interviewed in the information security space. Good interviews combine a mix of targeted questions, appropriate information sharing, and a goal of what you’d like to learn from a person and vice versa. Bad interviews… don’t. This leads to bad hires, good snowflakes being pushed aside, stupid questions being asked, people being sad pandas, poor team cohesion, and a general overwhelming feeling of meh. Do not despair, this is a solvable situation. Come join me on the journey to being less meh at hiring!

Wartortell works as a reverse engineer and malware researcher for Palo Alto Networks. Previously he worked in Threat Intel, Binary Rewriting and Binary Transparency. He also casts a mean Ice Punch, and this is not even his final form.

Aaron Bayles (@alxrogan) has been doing the Infosec song and dance since ’95. He has seen a million endpoints and rocked them all. He lives outside Houston and currently dabbles with all things Infosec and ICS/SCADA security.

Slides:

PowerShell Secrets and Tactics Ben0xA @ben0xa It used to be that most people were just starting to hear about PowerShell. Over the last 3 years, this has changed dramatically. We now see Offensive and Defensive PowerShell tools, exploits specifically leveraging PowerShell and WMI, and more organizations are starting to be intentional for detection and monitoring of PowerShell scripts and commands. With this visibility, it is becoming a game of cat and mouse to leverage and detect PowerShell. In this talk, I will highlight some secrets I use to ensure my PowerShell exploits are successful and some unique tactics which will bypass common defensive controls. I will also walk you through the creation of a custom PowerShell C# DLL which you can use to compromise your target. If you want to code with me, be sure to bring a laptop with Visual Studio 2013 or later installed. Ben Ten is a Senior Security Consultant with TrustedSec doing penetration testing and consulting. He has spent over 15 years doing Application & Web Development; Security Implementation, Consulting, & Training; Federal Regulation and Compliance oversight in relation to Information Technology (HIPAA, HITECH, PCI); and managing a team of developers and IT professionals. He is creator of the PoshSec Framework and works with the PoshSec development team. He has spoken at several conferences over the past 4 years including ShowMeCon, DerbyCon, BSides Chicago/Raleigh/Dallas Fort Worth, HackCon Norway, and more.

Slides:

Hunting for Exploit Kits Joe Desimone Joe – @dez_ Open any security blog and you are likely to find some information on the latest 0day being exploited in the wild by one or more of the popular exploit kits. Knowing how exploit kits are evolving over time allows researchers to validate a security stack against the latest capabilities, enables red teams to repurpose the latest in-the-wild threats, and assists vulnerability researchers to stay current on the latest exploits. However, getting samples or other specific insight into these changes is hard because direct access to tools is guarded and signatures are constantly changing. How can researchers identify and collect their own samples without any static signatures? This talk will reveal an automated system that relies on behavioral exploit detection rolled into a sandbox that continually crawls popular websites for infection. The system captures a steady stream of exploit kit samples which can support a wide range of research initiatives. We will also discuss samples from popular exploit kits that have been captured with this system such as Neutrino, RIG, and Magnitude. Joe Desimone is a Malware Researcher at Endgame. He has over 5 years of experience in the information security industry; primarily tracking and countering APTs, reverse engineering malware, and developing novel techniques and tools to empower hunt teams. Joe holds a BS and MS in Computer Security from RIT.

Slides:

“Better Network Defense Through Threat Injection and Hunting Zach Grace, Brian Genz Zach – @ztgrace, Brian – @briangenz Traditional penetration testing and red team engagements typically focus on identifying single attack paths and how organizations can fix vulnerabilities to shut those paths down. The results of these engagements are a reduced risk from eliminating a single attack path, but rarely lead to an improved defensive skill set. This talk will introduce the Threat Detection Maturity Model, a security detection and testing framework to more closely integrate red and blue team operations with the goal of measurably improving defensive capabilities. The framework is designed to measure the effectiveness of the blue team’s defensive capabilities using a capability maturity model across the attack lifecycle. We’ll demonstrate how “”””threats”””” are injected into an environment to enable a hunt team or SOC to improve their skill sets and validate the effectiveness of their security tooling. Zach has worked in offensive security for the last six years focusing on securing financial institutions. He is active in the Milwaukee security community in which he organizes @MilSec, is an OWASP Milwaukee chapter leader and is a member of the Wisconsin Collegiate Cyber Defense Challenge (CCDC) Red Team. He’s also the creator of the open source security projects Sticky Keys Hunter and changeme. Brian Genz is an information security professional with experience in the insurance, manufacturing, and defense intelligence sectors. He has worked in the areas of incident response, forensic analysis, vulnerability management, and security risk consulting.”

Breaking Credit Card Tokenization Without CryptanalysisTim MalcomVetter

Video: https://www.youtube.com/watch?v=17UcQohAjXw
Slides:

Credit Card Tokenization is a very popular antidote to costly and time-consuming PCI regulations, but are all implementations equally secure? Early studies on tokenization focused on the cryptanalysis of the token generation process, especially when early implementations sought to create 16 digit numeric tokens to satisfy constraints in legacy commerce systems. Fast forward to 2016, most of those problems do not exist today; however, anecdotes from consulting with Fortune 500s suggest other insecure properties not involving crypto can vary and emerge in tokenization systems.
This talk will dig into several sanitized examples from consulting engagements which reduce “PCI Compliant” Credit Card Tokenization from “silver bullet” to “speed bump” status when big-picture security controls are missing. Specifically: abusing separation of duties by rogue partial insiders via public APIs commonly found in e-commerce applications; discovery of accidental side channels of critical information flow, such as timing analysis or response differentiation, which can be abused to reveal full PANs (primary account numbers); whether DevOps cultures could promote rogue admins abusing tokenization presentation logic implemented in JavaScript; and for good measure: some common programming defects which at best render tokenization pointless, and at worst could allow for a breach. With each example, we’ll look at potential solutions.
MalcomVetter (@malcomvetter) has fifteen years in defending, building, and breaking systems. Tim is the Director of the Red Team at the world’s largest commercial entity, Walmart (@WalmartLabs), where he is privileged to lead a team of very skilled Red Team engineers testing one of the largest environments in the world (over 130 million IP addresses, petabytes of Big Data, thousands of applications, and millions upon millions of internal and external users).

Attacking EvilCorp: Anatomy of a Corporate Hack Sean Metcalf & Will Schroeder Sean Metcalf – @PyroTek3, Will Schroeder- @harmj0y With the millions of dollars invested in defensive solutions, how are attackers still effective? Why do defensive techniques seem to rarely stop or slow down even mid-tier adversaries? And is there anything the underfunded admin can do to stop the carnage? Join us in a shift to ?assume breach? and see how an attacker can easily move from a single machine compromise to a complete domain take over. Instead of “death by PowerPoint,” see first-hand how a fictional corporation suffers “death by a thousand cuts?. The fictional EvilCorp presents their top defensive tools and practically dares someone to attack the network. The battle of Red vs. Blue unfolds showing EvilCorp’s network submit to the unrelenting attacks by an experienced adversary. When the dust settles, the Red Team looks victorious. But what, if anything, could have tipped the scales in the other direction? In this demo-heavy session (several demos are shown to demonstrate modern attack effectiveness), we showcase the latest attack techniques and ineffective defenses still used to protect companies. Defense evasion tools and techniques are detailed as well as attack detection methods. Effective mitigation strategies are highlighted and the Blue Team is provided a roadmap to properly shore up defenses that can stop all but the most determined attacker. Sean Metcalf (@PyroTek3) is founder & principal security consultant of Trimarc and is one of about 100 people in the world who holds the Microsoft Certified Master Directory Services (MCM) certification. He is also a Microsoft MVP and has presented on Active Directory attack and defense at BSides, Shakacon, Black Hat, DEF CON, and DerbyCon security conferences. Will Schroeder (@harmj0y) is an Information Security Researcher and red teamer for Veris Group?s Adaptive Threat Division. He is the co-founder the Veil-Framework, PowerTools, and PowerShell Empire, and has presented at ShmooCon, Defcon, Derbycon, and various Security BSides on topics spanning AV-evasion, post-exploitation, red teaming, offensive PowerShell, and more.

Living Off the Land 2: A Minimalist’s Guide to Windows Defense Matt Graeber and Jared Atkinson – @mattifestation The ?living off the land? philosophy, as applied to InfoSec, is the idea that one can thrive using mostly the tools present in a target environment in an effort to remain hidden from an adversary. While historically this philosophy has been applied to offense, it is equally applicable to defense. A capable defender, ideally, should introduce a minimal forensic footprint into an environment suspected to be compromised. Additionally, informed defenders should have an awareness of attacker objectives which includes performing reconnaissance against common security products, most of which consume a substantial OS fingerprint. This talk aims to introduce defenders to defensive capabilities built-in to all versions of Windows which are likely to leave adversaries in dark as to what defensive mechanisms are in place. Expensive defensive products are not always the solution when you?re already sitting on a goldmine of free, unexploited capabilities. Matt Graeber is a reverse engineer and security professional who knows some things about things but is otherwise a complete noob in many facets of life. Matt is commonly known as that guy who took Dave Kennedy and Josh Kelley?s original PowerShell talk and turned it into an unhealthy obsession for which he still hasn?t broken himself of. Matt prides himself not on his industry speaking engagements, certifications, or experience but rather the journey that took him to his present situation – surrounded by motivated, brilliant, and genuinely good people.

Introducing DeepBlueCLI, a PowerShell module for hunt teaming via Windows event logs Eric Conrad @eric_conrad A number of events are triggered in Windows environments during virtually every successful breach, these include: service creation events and errors, user creation events, extremely long command lines, compressed and base64 encoded PowerShell functions, and more. Microsoft has added a wealth of blue team tools to its operating systems, including native support of logging the full command line used to launch all processes, without requiring 3rd party tools (or Sysmon). KB3004375 adds this feature to Windows 7 and Server 2008R2. DeepBlueCLI can automatically determine events that are typically triggered during a majority of successful breaches, including use of malicious command lines including PowerShell. Eric Conrad’s career began in 1991 as a UNIX systems administrator for a small oceanographic communications company. He gained information security experience in a variety of industries, including research, education, power, Internet, and health care. He is now CTO of Backshore Communications, a company focusing on hunt teaming, intrusion detection, incident handling, and penetration testing.

Attackers Hunt Sysadmins – It’s time to fight back Lee Holmes – @Lee_Holmes What do the NSA, APT groups, and run-of-the-mill attackers have in common? They. Hunt. Sysadmins. After all, what?s a better way to compromise an entire infrastructure than to target the folks with complete and unconstrained access to it? It?s time to fight back. In this talk, we introduce PowerShell Just Enough Administration, a powerful platform capability that lets you add role-based access controls to your existing PowerShell-based remote management infrastructure. Lee Holmes is the lead security architect of Microsoft’s Enterprise Cloud Group, covering Windows Server, Azure Stack, System Center, and Operations Management Suite.

Scripting Myself Out of a Job – Automating the Penetration Test with APT2 Adam Compton, Austin Lane Adam – @tatanus , Austin – @capndan Nearly every penetration test begins the same way; run a NMAP scan, review the results, choose interesting services to enumerate and attack, and perform post-exploitation activities. What was once a fairly time consuming manual process, is now automated! Automated Penetration Testing Toolkit (APT2) is an extendable modular framework designed to automate common tasks performed during penetration testing. APT2 can chain data gathered from different modules together to build dynamic attack paths. Starting with a NMAP scan of the target environment, discovered ports and services become triggers for the various modules which in turn can fire additional triggers. Have FTP, Telnet, or SSH? APT2 will attempt common authentication. Have SMB? APT2 determines what OS and looks for shares and other information. Modules include everything from enumeration, scanning, brute forcing, and even integration with Metasploit. Come check out how APT2 will save you time on every engagement. “dam Compton has been a programmer, researcher, professional pentester, and farmer. Adam has over 15 years of programming, network security, incident response, security assessment, and penetration testing experience.

DNS in Enterprise IR: Collection, Analysis and Response Philip Martin @SecurityGuyPhil DNS is an often-overlooked and under-tooled area of security data collection, analysis and response. We will first review existing tools and deployment choices for collecting DNS data and release the 1.0 version of my own network DNS capture tool, gopassivedns. We will then explore several example analytical approaches to large scale DNS data, including approaches to finding DNS tunneling and discovering attacker infrastructure. Finally, we take a look at how DNS can play a part in remediation and release a second tool, a RESTful interface to RPZ, goRPZ. Attendees will walk away able to implement or improve DNS collection and analysis in their environments. Philip leads security at Coinbase, where he is continually amazed at the amount of attacker effort and creativity inspired by half a billion dollars of cryptocurrency. Philip also enjoys spending time with his family and making delicious smoked meats.

Attacking ADFS Endpoints with PowerShell Karl Fosaaen – @kfosaaen Active Directory Federation Services (ADFS) has become increasingly popular in the last few years. As a penetration tester, I’m seeing organizations opening themselves up to attacks on ADFS endpoints across the Internet. Manually completing attacks against these endpoints can be tedious. The current native Microsoft management tools are handy, but what if we weaponized them. During this talk, I will show you how to identify domains that support ADFS, confirm email addresses for users of the domain, and help you guess passwords for those users. We’ll cover how you can set up your own hosted ADFS domain (on the cheap), and use it to attack other federated domains. On top of that, we’ll show you how you can wrap all of the native functionality with PowerShell to automate your attacks. This talk should give penetration testers an overview on how they can start leveraging ADFS endpoints during a penetration test. Karl is a Managing Consultant with NetSPI who specializes in network and web application penetration testing. With over eight years of consulting experience in the computer security industry, he has worked in a variety of industries and has made his way through many Active Directory domains. Karl also holds a BS in Computer Science from the University of Minnesota. This year, he has spent a fair amount of time digging into the Skype for Business APIs. Prior to that, Karl has helped build out and maintain NetSPI’s GPU cracking boxes. Karl holds a couple of certifications, that is neat. Karl has previously spoken at THOTCON, BSidesMSP, Secure360, and AppSec California. In his spare time, you may see him trying to sell you a t-shirt as a swag goon at DEF CON.

Introducing PowerShell into your Arsenal with PS>Attack Jared Haight – @jaredhaight PS>Attack is a custom tool that was created to make it easier for Penetration Testers to incorporate PowerShell into their bag of tricks. It combines a lot of the best offensive tools from the offensive PowerShell community into a custom, encrypted console that emulates a PowerShell environment. It also includes a custom command, “Get-Attack” to act a search engine for attacks making it easy to find the right attack for any situation. In this presentation we will cover how PowerShell can be used during every part of a penetration test and how PS>Attack can help make the whole process a lot easier. Jared Haight (@jaredhaight) spent 10 years as a Systems Administrator where (once it came out) he used PowerShell to handle any task that he had to do more than once. Now as a Penetration Tester for Gotham Digital Science, he uses his knowledge of PowerShell on engagements to help companies improve their security posture. He has spent the last four years teaching people how to use PowerShell and created the PS>Attack platform to help Penetration Testers easily add PowerShell to their toolkit.

Hardening AWS Environments and Automating Incident Response for AWS Compromises Andrew Krug & Alex McCormack @andrewkrug @amccormack Incident Response procedures differ in the cloud versus when performed in traditional, on-premise, environments. The cloud offers the ability to respond to an incident by programmatically collecting evidence and quarantining instances but with this programmatic ability comes the risk of a compromised API key. The risk of a compromised key can be mitigated but proper configuration and monitoring must be in place. The talk discusses the paradigm of Incident Response in the cloud and introduces tools to automate the collection of forensic evidence of a compromised host. It highlights the need to properly configure an AWS environment and provides a tool to aid the configuration process. Andrew Krug is a Senior Software Engineer at a large cyber security company. Krug has been Consultant, Network Architect, Systems Administrator, Operations Manager, Technical Trainer, and Software Engineer. Currently Krug works to develop gamified security education through security simulation scenarios and rich interactive content. Alex McCormack is a Principal Software Developer at a large cyber security company. Alex assists in the design and implementation of Capture the Flag competitions and training events. Alex has designed CTF challenges since 2013 and given training since 2012. Prior to developing CTFs, Alex worked in Incident Response and Malware Analysis.

Blog Post: https://foxglovesecurity.com/2016/09/26/rotten-potato-privilege-escalation-from-service-accounts-to-system/

At Shmoocon early this year, we released Potato, a new method and tool that took advantage of neglected 15 year old issues in all versions of Windows to elevate any user’s privilege to SYSTEM in default configurations. We had planned on releasing a much improved version of said tool here at Derbycon, but Microsoft had other plans. On June 14, 2016 we were surprised to find that Microsoft released MS16-075 which seems to break Potato. Luckily we still have one more trick up our sleeves that has proved useful in real-life scenarios. We will be discussing a technique based on the Potato exploit that allows for elevation from many Windows service accounts (such as those used by IIS and SQL Server) to SYSTEM in default configurations on all Windows versions.

 

Fire Away! Sinking the Next Gen Firewall – Russell Butturini

Fire Away! Sinking the Next Gen Firewall Russell Butturini @tcstoolhax0r Recently, the next generation or “application aware” firewall has come onto the scene as the next logical progression of firewall technology and the platform of choice for enterprise traffic filtering needs. However, many vendors have overstated the capabilities of these firewalls and how the underlying technology really works. This talk will examine how next generation firewalls make decisions and how application awareness works, and then dive into the security tradeoffs they make in the name of performance. A new tool, Fireaway, will be demoed to show how the techniques covered in this talk can be automated to completely bypass firewall rules, exfiltrate data and establish obfuscated command and control channels through the firewall, all while looking like normal user activity. Russell Butturini is the senior enterprise security architect at a large healthcare company in Franklin TN. He occasionally has good ideas and he presents on them at places such as DEFCON, Derbycon, and various BSides. In his free time, he has a compulsive gambling problem when it comes to betting on horse races, so he’s hoping the Derbycon goons make sure he shows up for this talk and isn’t on a multi day gambling bender at Churchill Downs.

 

 

This post is a collection of my favorite and interesting talks from DerbyCon 6 (2016). There were a lot of great talks and as I discover them, I’ll add them here. My goal is to collect and provide the talk videos and slides together for a single, easy reference. I’m sure I missed a few.
