The Internet of Things (IoT) is not new terminology. However, the sheer amount of connected devices we have at home and at our businesses is growing exponentially and increasing the attack surface. Attacking and assessing IoT can easily lead us down a rabbit hole only to hit a wall on the other side. However we need to be extremely comprehensive in our methodology and not end up down that rabbit hole for too long. We’re here to discuss the attack footprint of a typical IoT infrastructure, whether at home or at the office. We will discuss a threat model and verification of a real-world IoT assessment including every component from hardware, protocols, mobile applications and devices, web APIs, etc. We will discuss attack vectors, attack motivation, typical attack vectors, and common shortfalls in IoT systems. Join David as he walks through an assessment of an IoT system including a high level threat model and attack chain discussion.

For over 10 years, Visual Studio has provided basic source code analysis through FxCop and StyleCop. While these code analyzers focus mainly on design conformance, code consistency, and best practices, there is very little support for enforcing secure coding techniques. To address this gap, Microsoft started a project back in 2011 called CAT.NET to help identify secure coding bugs such as XSS, SQL Injection, and XPath Injection. Unfortunately, CAT.NET failed and never made it past the first version. Aside from purchasing expensive commercial static analysis tools, .NET development teams have been left without an easy way to integrate secure code scanning rules into Visual Studio. At least until now…

With the release of Visual Studio 2015, the open-source .NET Compiler Platform (aka “Roslyn”) exposes a set of code analysis APIs capable of querying the source code, identifying a security issue, and reporting it as code is written! In this talk, we will explore the code analysis APIs, teach you how to create a live static analysis rule, and introduce you to Puma Scan: an open-source static analysis rules engine. Come prepared to see a live demonstration of the Puma hunting source code for vulnerabilities, and walk away with a static analysis engine to help secure your organization’s .NET applications.

Speaker: Ben Schmitt

Talk: Defense Wins Championships


Ben Schmitt is the Director of Information Security @ Dwolla. Prior to this role, Ben held the position of Global Director, IT Security & Compliance at the Danfoss Group responsible for Network and Application security (including ERP systems). Ben is a Wisconsin native hailing from Manitowoc, WI (yes, he has watched Making a Murderer) and started his InfoSec career with TDS Telecom in Madison, WI covering ISP and Enterprise security as a Security Architect.


My name is Ben and I play defense. Let me tell you why I think defense wins championships.

My father is a retired firefighter and I often times naturally think about the evolution of the fire service. The fire service has shifted from putting out fires as fast as possible with great equipment, carefully placed fire stations and rapid response to significant investments in fire prevention and survival such as education, inspections, building codes and careful design. Simply put: don’t just build faster and bigger fire trucks…focus on preventing or mitigating the damn fires in the first place.

So, what does this mean when compared to Information Security? Information Security has a current fascination with playing offense and for good reason. You can’t play great defense without knowledge of the offense. If you can’t run nmap, tcpdump or a proxy to meddle with things, it’s going to be hard to play defense. You need some knowledge of offense to make sure your defensive controls actually perform as-expected.

Despite the need for offensive knowledge, I am concerned with the industry’s absolute fascination with offense. Penetration testing is all the rage – breaking things, pivoting around an organization and pillaging sysadmins to uncover high-value data can be perhaps exciting? It seems that most resumes which cross my desk must include Kali Linux for a coolness factor. Maybe it is a result of Mr. Robot or maybe people just think breaking things is the pinnacle of achievement in a win/loss scenario.

We going to go point/counterpoint in this talk to focus on the glory of playing defense. Offense wants to sniff traffic, then defense ensures proper TLS is enforced. Offense wants to steal credentials, then defense ensures MFA is required. Offense wants to brute force a web app form, defense ensures throttling and CAPTCHAs. Offense wants to brute force password hashes offline, defense ensures Argon2 is waiting. Offense wants to spoof, tamper, repudiate, disclose information, denial of service or elevate privilege, defense performs threat modeling.

A football team’s defense keeps points off the board and can turn a fumble into an opportunity. Defense matters and wins championships. Let’s take some time to glorify the defenders out there.

We will analyze the details of recent attack trends such as the use of PowerShell, process hollowing and application whitelist bypasses, shellcode, encrypted payloads and embedded content. We will also explore techniques used by malicious documents that do not rely on macros and even samples targeting OS X. This will be a fast-paced talk that will prepare you to deal with any malicious document.

Speaker: Andrew Freeborn

Talk: Want to break JavaScript and APIs in web apps?


Andrew Freeborn is a security junkie who provides product expertise from a background of pen testing, custom exploitation development, and software development. From the perspective of a hacker, he specializes in secure software development validation for software and web applications. Prior to joining Tenable, Andrew served as a Senior Penetration Tester for a national financial organization, providing technical assistance with penetration testing of mobile and web applications, analysis of multiple in-house developed APIs, and software source code security review.


Learn how to identify, exploit, and choose remediation options for JavaScript and APIs. As modern web applications are integrating more JavaScript frameworks and adding APIs, the added complexity leaves the web app more prone to security issues. Security testers need to ensure these frameworks and APIs are safe to use and implemented correctly. Using an intentionally broken OWASP project, let’s dive into some tactical skills for improving the security environment.

Speaker: Brad Duncan

Talk: Exploit Kits and Indicators of Compromise


Brad Duncan specializes in network traffic analysis and exploit kit detection. After more than 21 years of classified intelligence work for the US Air Force, Brad transitioned to cyber security in 2010. He is currently a Threat Intelligence Analyst for Palo Alto Networks Unit 42. Brad is also a volunteer handler for the Internet Storm Center (ISC) and has posted more than 80 diaries at isc.sans.edu. He routinely blogs technical details and analysis of infection traffic at www.malware-traffic-analysis.net.


Exploit kits are a well known method used by criminals to distribute malware. Many security professionals know about exploit kits, but the full sequence of events is often misunderstood. In this presentation, Brad explains the concept behind a successful malware infection by criminals using exploit kits. This talk traces the sequence of events, starting with a compromised website and ending with the exploit kit delivering its malware payload.

Different steps of an exploit kit’s kill chain are sometimes identified through an organization’s intrusion detection system (IDS). These IDS alerts provide indicators of compromise (IOC). However, in many cases the kill chain is incomplete, and no infection has occurred. Brad discusses examples of exploit kits detected in a security operations center (SOC) environment, how analysts investigate this activity, and the overall impact to an organization.
