This presentation documents how Egress-Assess can be used on assessments to simulate exfiltrating data over a variety of protocols. Additionally, this presentation documents the addition of malware modules into Egress-Assess. The new malware modules allow users to emulate different pieces of malware families by using documented malware indicators.

Security in PHP Applications: An absolute must! Is you application secure? What does securely written code look like? In this presentation we will talk about what it takes to make a PHP application be written securely. We will focus on secure coding practices and discuss vulnerabilities that must be addressed, including SQL injection, XSS, user authentication and authorization, data validation, and data integrity. There will be example code and working examples to show you what works and what doesn't. We will also discuss how to bake security into system development life cycle and how to convince management that security issues must be addressed. You will come out of this presentation ready to become the Security Hero you've always wanted to be!

Same-origin policy is an important security concept of the modern browser languages like JavaScript but becomes an obstacle for developers when building complex client-side apps. Over time there have been lots of ingenious workarounds using JSON-P, IFRAME and proxies. As of January 2013 the well known Cross Origin Resource Sharing (CORS) comes as proposed standard by W3C and has now native support by all major browsers.

The open source TodoMVC project implements a Todo application using popular JavaScript MV* frameworks. Some of the implementations add support for compile to JavaScript languages, module loaders and real time backends. This presentation will demonstrate a TodoMVC implementation which adds support for the forthcoming W3C Web Cryptography API, as well as review some key cryptographic concepts and definitions. Instead of storing the Todo list as plaintext in localStorage, this "secure" TodoMVC implementation encrypts Todos using a password derived key. The PBKDF2 algorithm is used for the deriveKey operation, with getRandomValues generating a cryptographically random salt. The importKey method sets up usage of AES-CBC for both encrypt and decrypt operations. The final solution helps address item "A6-Sensitive Data Exposure" from the OWASP Top 10. With the Web Cryptography API being a recommendation in 2014, any Q&A time will likely include browser implementations and limitations, and whether JavaScript cryptography adds any value.

The widespread demand for online privacy, also fueled by widely-publicized demonstrations of session hijacking attacks against popular websites (see Firesheep), has spearheaded the increasing deployment of HTTPS. However, many websites still avoid ubiquitous encryption due to performance or compatibility issues. The prevailing approach in these cases is to force critical functionality and sensitive data access over encrypted connections, while allowing more innocuous functionality to be accessed over HTTP. In practice, this approach is prone to flaws that can expose sensitive information or functionality to third parties. In this work, we conduct an in-depth assessment of a diverse set of major websites and explore what functionality and information is exposed to attackers that have hijacked a user's HTTP cookies. We identify a recurring pattern across websites with partially deployed HTTPS; service personalization inadvertently results in the exposure of private information. The separation of functionality across multiple cookies with different scopes and inter-dependencies further complicates matters, as imprecise access control renders restricted account functionality accessible to non-session cookies. Our cookie hijacking study reveals a number of severe flaws; attackers can obtain the user's home and work address and visited websites from Google, Bing and Baidu expose the user's complete search history, and Yahoo allows attackers to extract the contact list and send emails from the user's account. Furthermore, e-commerce vendors such as Amazon and Ebay expose the user's purchase history (partial and full respectively), and almost every website exposes the user's name and email address. Ad networks like Doubleclick can also reveal pages the user has visited. To fully evaluate the practicality and extent of cookie hijacking, we explore multiple aspects of the online ecosystem, including mobile apps, browser security mechanisms, extensions and search bars. To estimate the extent of the threat, we run IRB-approved measurements on a subset of our university's public wireless network for 30 days, and detect over 282K accounts exposing the cookies required for our hijacking attacks. We also explore how users can protect themselves and find that, while mechanisms such as the EFF's HTTPS Everywhere extension can reduce the attack surface, HTTP cookies are still regularly exposed. The privacy implications of these attacks become even more alarming when considering how they can be used to deanonymize Tor users. Our measurements suggest that a significant portion of Tor users may currently be vulnerable to cookie hijacking. (Source: Black Hat USA 2016, Las Vegas)

This workshop introduces to WebRTC and how you can utilize its open API to develop Rich Communication services in your web applications. It describes a general Java gateway to allow the translation of WebRTC to SIP, the protocol used internally in the majority of VoIP networks and how Groovy is used to empower the process. In the end of the workshop, the assistants will be able to develop and deploy a basic webpage and they will have the knowledge to customize the example and develop more complex features, adding audio, video or data to HTML5, iOS or Android applications.

Data spaces in distributed environments should be allowed to evolve in agile ways providing data space owners with large flexibility about which data they store. Agility and heterogeneity, however, jeopardize data exchanges because representations may build on varying ontologies and data consumers may not rely on the semantic correctness of their queries in the context of semantically heterogeneous, evolving data spaces. Graph data spaces are one example of a powerful model for representing and querying data whose semantics may change over time. To assert and enforce conditions on individual graph data spaces, shape languages (e.g SHACL) have been developed. We investigate the question of how querying and programming can be guarded by reasoning over SHACL constraints in a distributed setting and we sketch a picture of how a future landscape based on semantically heterogeneous data spaces might look like.

Azure Native Qumulo scales elastically for common High Performance Compute (HPC) workloads based on application requirements for: Financial Services, Automotive, Genomics / Life Sciences, Media and Entertainment, Energy, Oil and Gas, etc. Performance can be dialed UP (and back down) much higher than the examples shown here. These slides offer a glimpse into ANQ's HPC capabilities, although at a smaller scale. We invite YOU to do your own testing (with a free ANQ trial) and work with us to test your HPC workloads in Azure.
