Some wish for cyber safety, which they will not get. Others wish for cyber order, which they will not get. Some have the eye to discern cyber policies that are . Keynote Transcript. Briefings. Over the past year, more than 1. Matasano crypto challenges, a staged learning exercise where participants implemented 4. In the process, we collected crypto exploit code in dozens of different languages, ranging from X8.
Haskell. With the permission of the participants, we've built a . We'll explain the importance of each of the attacks, putting them into the context of actual software flaws. Our challenges cover crypto concepts from block cipher mode selection to public key agreement algorithms. For some of the more interesting attacks, we'll step- by- step the audience through exploit code, in several languages simultaneously.

IEEE 8. 02. 1x has been leveraged for a long time for authentication purposes. Up until this point, little has been done to help researchers expose vulnerabilities within the systems that implement the protocol.
In this talk, we'll dissect IEEE 8. RADIUS/EAP), provide testing tools, and detail a number of vulnerabilities identified in popular supporting systems. We'll wrap up demonstrating a vulnerability within a RADIUS server that allows for remote code execution over 8. WPA Enterprise before the user is authorized to join the network. Many point- of- sale breaches occurred in the past year and many organizations are still vulnerable against the simplest exploits. In this presentation, I explain about how points- of- sale get compromised from both retailer's and software- vendor's perspective.

One of the most common threats is memory scraping, which is a difficult issue to solve. Hence, I would like to share with you a demonstration of how it works and what can be done in order to minimize this threat. During this presentation, I will explain the long journey to understand how to mitigate it, while walking through the concepts (not exposing vendor names) that don't work and those that can work.

The secure BYOD hype is growing and Virtual Desktop Infrastructure (VDI) is considered the alternative solution for secure containers. In a nutshell, VDI solutions provide a remote workstation offering so that no data is stored locally. We decided to examine the architecture and see for ourselves whether VDI delivers on its security promise. By simulating the user's interaction, we show how such an attack is not only feasible - but also efficient. While keeping the espionage activity invisible both from client- side and server- side malware detection measures, the attacker can automate the process and ultimately render the VDI solution ineffective.
The millions of unique malicious binaries gathered in today's white- hat malware repositories are connected through a dense web of hidden code- sharing relationships. If we could recover this shared- code network, we could provide much needed context for and insight into newly observed malware. For example, our analysis could leverage previous reverse engineering work performed on a new malware sample's older . Various approaches have been proposed to see through malware packing and obfuscation to identify code sharing. As part of the algorithm description I will walk through a Python machine learning library that we will be releasing in the conference material which allows users to detect feature frequencies over billions of items on commodity hardware. Automotive security concerns have gone from the fringe to the mainstream with security researchers showing the susceptibility of the modern vehicle to local and remote attacks.
A malicious attacker leveraging a remote vulnerability could do anything from enabling a microphone for eavesdropping to turning the steering wheel to disabling the brakes. Unfortunately, research has only been presented on three or four particular vehicles. Each manufacturer designs their fleets differently; therefore analysis of remote threats must avoid generalities. This talk takes a step back and examines the automotive network of a large number of different manufacturers from a security perspective. From this larger dataset, we can begin to answer questions like: Are some cars more secure from remote compromise than others? Has automotive network security changed for the better (or worse) in the last five years? What does the future of automotive security hold and how can we protect our vehicles from attack moving forward?
Consumer Premise Equipment (CPE) has become common, nearly ubiquitous, home and small office attire. Many homes have a router/modem device that mediates access between home devices and the ISP. Abuse of these devices is particularly problematic both because the owner has difficulty interfacing with (and fixing) the device and because the static code provided by the vendor is generally rotted (and vulnerable) by the time the consumer unpacks the device. The poor management of CPE has created an Internet- scale problem and potential for abuse.
For example, the plurality of open DNS resolvers accessible on the Internet are on medium- speed DSL connections, the sorts of connections leased to home and small- business users. These devices are available for abuse in reflected and amplified DDo. S attacks. The vulnerable devices themselves can also be leveraged against the consumer in middleperson attacks.
In this presentation, we quantify this problem and provide recommendations for how the Internet community can address this public- health- like problem. Microsoft Active Directory uses Kerberos to handle authentication requests by default. However, if the domain is compromised, how bad can it really be? With the loss of the right hash, Kerberos can be completely compromised for years after the attacker gained access.
Yes, it really is that bad. In this presentation Skip Duckwall, @passingthehash on twitter and Benjamin Delpy, @gentilkiwi on twitter and the author of Mimikatz, will demonstrate just how thoroughly compromised Kerberos can be under real world conditions. Prepare to have all your assumptions about Kerberos challenged! The primary goal of ASLR is to effectively randomize a program's memory layout so that adversaries cannot easily infer such information. As ASLR is a critical defense against exploitation, there have been tremendous efforts to evaluate the mechanism's security.
To date, previous attacks that bypass ASLR have focused mostly on exploiting memory leak vulnerabilities, or abusing non- randomized data structures. In this presentation, we leverage vulnerabilities introduced by performance- oriented software design to reveal new ways in which ASLR can be bypassed. In addition to describing how vulnerabilities originate from such designs, we will present real attacks that exploit them. First, we analyze general hash table designs for various programming languages (Java. Script, Python, Ruby). To optimize object tracking for such languages, their interpreters may leak address information. Some hash table implementations directly store the address information in the table, whileothers permit inference of address information through repeated table scanning.
We exhaustively examined several popular languages to see whether each of them has one or both of these problems, and present how they can be leveraged. As a concrete example, we demonstrate how address information can be leaked in the Safari web browser by simply running some Java. Script. Second, we present an analysis of the Zygote process creation model, which is an Android operating system design for speeding up application launches. The results of our examination show that Zygote weakens ASLR because all applications are created with largely identical memory layouts. To highlight the severity of this issue, we demonstrate two different ASLR bypass attacks using real applications - Google Chrome and VLC Media Player. The team that discovered the Android Master. Key vulnerability in 2.
Android vulnerability with widespread impact: a flaw in Android application handling, allowing malicious applications to escape the normal application sandbox and get special security privileges without any user notification. This can lead to a malicious application having the ability to steal user data, recover passwords and secrets, or in certain cases, compromise the whole Android device. The presentation will also coincide with the release of a free security scanning tool to help end- users scan for risk of this vulnerability on their end devices. Advanced Persistent Threat (APT) attacks are highly organized and are launched for prolonged periods. APT attacks exhibit discernible attributes or patterns. In order to maintain the command and control (c.
APT attacks are generally embedded with multiple DNS names. An intuitive view is that APT attackers keep and control a high number of DNS- IP address pairs. Most of existing malware attribution works placed great emphasis on grouping the technological or behavioral contexts from the malware binaries. Our study indicates that the attackers follow some behavioral patterns of registering DNS domains and the frequently use of stable DNS- IP pairs. The gatherings of such evidence regarding malware binaries are not complicated. But it requires tedious online queries of open source information. We developed an automated solution to simplify the tasks of collecting and storing the information as a database for future analysis.
Once the initial set of malicious DNS- IP pair, . This database can be used for further analysis by a visualization tool, and for identification of the possible identity or personas of the attackers.
In our studies, we used Maltego for the analysis. While there has certainly been some interesting research into the security of mobile broadband modems, or . The level of skill and effort required to execute such an attack reduces the potential number of attackers, but there are easier ways to monetize from attacking these devices too.
