Abusing Adobe Reader’s JavaScript APIs
Brian Gorenc Manager, HP’s Zero Day Initiative
Abdul-Aziz Hariri Security Researcher, HP’s Zero Day Initiative
Jasiel Spelman Security Researcher, HP’s Zero Day Initiative
Adobe Reader’s JavaScript APIs offer a rich set of functionality for document authors. These APIs allow for processing forms, controlling multimedia events, and communicating with databases, all of which provide end-users the ability to create complex documents. This complexity provides a perfect avenue for attackers to take advantage of weaknesses that exist in Reader’s JavaScript APIs.

In this talk, we will provide insight into both the documented and undocumented APIs available in Adobe Reader. Several code auditing techniques will be shared to aid in vulnerability discovery, along with numerous proofs-of-concept which highlight real-world examples. We’ll detail out how to chain several unique issues to obtain execution in a privileged context. Finally, we’ll describe how to construct an exploit that achieves remote code execution without the need for memory corruption.

Hacking Smart Safes: On the "Brink" of a Robbery
Dan “AltF4” Petro Security Associate, Bishop Fox
Oscar Salazar Senior Security Associate at Bishop Fox
Have you ever wanted to crack open a safe full of cash with nothing but a USB stick? Now you can!

The Brink’s CompuSafe cash management product line provides a “smart safe as a service” solution to major retailers and fast food franchises. They offer end-to-end management of your cash, transporting it safely from your storefront safe to your bank via armored car.

During this talk, we’ll uncover a major flaw in the Brink’s CompuSafe and demonstrate how to crack one open in seconds flat. All you need is a USB stick and a large bag to hold all of the cash. We’ll discuss how to remotely takeover the safe with full administrator privileges, and show how to enumerate a target list of other major Brink’s CompuSafe customers (exposed via configuration files stored right on the safe).

At any given time, up to $240,000 can be sitting in each of the 14,000 Brink’s CompuSafe smart safes currently deployed across the United States - potentially billions of dollars just waiting to be stolen.

So come ready to engage us as we explore these tools and more in this DEMO-rich presentation. And don’t forget to call Kenny Loggins... because this presentation is your highway to the Danger Zone...

Note - This presentation is about exposing flaws in the Brinks’s Compusafe to improve security and allow pentesters to demonstrate these flaws to their customers. Please use this information responsibly.

NSM 101 for ICS
Chris Sistrunk Sr. ICS Security Consultant, FireEye

Is your ICS breached? Are you sure? How do you know?

The current state of security in Industrial Control Systems is a widely publicized issue, but fixes to ICS security issues are long cycle, with some systems and devices that will unfortunately never have patches available. In this environment, visibility into security threats to ICS is critical, and almost all of ICS monitoring has been focused on compliance, rather than looking for indicators/evidence of compromise. The non-intrusive nature of Network Security Monitoring (NSM) is a perfect fit for ICS. This presentation will show how NSM should be part of ICS defense and response strategy, various options for implementing NSM, and some of the capabilities that NSM can bring to an ICS security program. Free tools such as Security Onion, Snort IDS, Bro IDS, NetworkMiner, and Wireshark will be used to look at the ICS environment for anomalies. It will be helpful if attendees have read these books (but they aren't required): The Cuckoo's Egg by Cliff Stoll, The Practice of Network Security Monitoring by Richard Bejtlich, and Applied Network Security Monitoring by Chris Sanders and Jason Smith.

Chris Sistrunk is a Senior Consultant at Mandiant, focusing on cyber security for industrial control systems (ICS) and critical infrastructure.

Introduction to SDR and the Wireless Village
DaKahuna
satanklawz

In many circumstances, we all have to wear different hats when pursuing hobbies, jobs and research. This session will discuss the exploration and use of software defined radio from two perspectives; that of a security researcher and Ham Radio operator. We will cover common uses and abuses of hardware to make them work like transceivers that the Ham crowed is use too, as well as extending the same hardware for other research applications. Additionally we will highlight some of the application of this knowledge for use at The Wireless Village! Come and join this interactive session; audience participation is encouraged.

By day DaKahuna works for a small defense contractor as a consultant to large government agencies providing critical reviews of customer organizations compliance with Federal Information Systems information Security Act (FISMA) requirements, effectiveness of their implementation of National Institute for Science and Technology (NIST) Special Publication requirements, cyber security policies, cyber security program plans, and governmental standards and guidance. By night he enjoys roaming the airwaves , be it the amateur radio bands or wireless networks. He is a father of two, grandfather to three, 24 year Navy veteran communicator, holder of an amateur radio Extra Class license and a staunch supporter and exerciser of his 2nd Amendment rights who enjoys shooting targets out to 1200 yards.

Satanklawz has been in the information security realm for 15 years. He built and sold a wireless ISP, worked info sec in the financial services industry and now is a public servant of sorts. His hobbies and interests have always involved radio in some sort of fashion. When he has spare time, he is completing his PhD, teaches, create mischief, and is working on his dad jokes.

Flowers, red and blue,

satanklawz loves *SDR*.

This is a haiku.

One Device to Pwn Them All
Dr. Phil Polstra Professor, Bloomsburg University
This talk will present a device that can be used as a dropbox, remote hacking drone, hacking command console, USB writeblocker, USB Mass Storage device impersonator, or scripted USB HID device. The device is based on the BeagleBone Black, can be battery operated for several days, and is easily constructed for under $100.

The dropbox, remote hacking drone, and hacking command console functionality were presented at DEF CON 21. This talk will emphasize the new USB-based attack functionality. Topics will include injecting payloads by emulating an optionally write-protected USB mass storage device, rapidly executing commands on a target using the BeagleBone Black operating as a scripted USB HID device, USB mass storage device impersonation, and other attacks that can be performed with brief physical access to the target.

Some familiarity with Linux and USB devices would be helpful, but not required. All hardware and software to be discussed is 100% open source.

Phil was born at an early age. He cleaned out his savings at age 8 in order to buy a TI99-4A computer for the sum of $450. Two years later he learned 6502 assembly and has been hacking computers and electronics ever since.

Dr. Phil currently works as a professor at Bloomsburg University of Pennsylvania. His research focus over the last few years has been on the use of microcontrollers and small embedded computers for forensics and pentesting. Phil has developed a custom pentesting Linux distro and related hardware to allow an inexpensive army of remote pentesting drones to be built using the BeagleBone Black computer boards. This work is described in detail in Phil's book "Hacking and Penetration Testing With Low Power Devices" (Syngress, 2015).

Prior to entering academia, Phil held several high level positions at well-known US companies. He holds a couple of the usual certs one might expect for someone in his position. When not working, he likes to spend time with his family, fly, hack electronics, and has been known to build airplanes.
