Don't Be A Victim

Presented by: Jack Daniel

Don’t you hate it when you are minding your own business, in a familiar place, in the right time…and you end up in a strange place, in the wrong time, maybe even the wrong century? In this talk I will provide tips and tricks for dealing with this all-too-common tragedy. Don’t be a victim, be prepared.

(This is actually an informative, yet lighthearted introduction to the topic of pragmatic, risk-based security, but without using terms like “risk-based security”. There are two target audiences for this talk, those who need a non-technical introduction to thinking about risk, threat modeling, and security, and those interested in using “subversive education” to get their message out to an audience).

Google & Search Hacking

Presented by: Francis Brown

Last year’s Lord of the Bing presentation stabbed Google Hacking in the heart with a syringe full of adrenaline and injected life back into a dying art form. New attack tools and modern defensive techniques redefined the way people thought about Google Hacking. Among these were the first ever Bing Hacking tool and the Google/Bing Hacking Alert RSS feeds, which have grown to become the world’s single largest repository of live vulnerabilities on the web. And it was only the beginning…

This year, we once again tear down the basic assumptions about what Google/Bing Hacking is and the extent to which it can be exploited to target organizations and even governments. In our secret underground laboratory, we’ve been busy creating an entirely new arsenal of Diggity Hacking tools. Just a few highlights of the new tools are:

  • BaiduDiggity – first ever Baidu hacking tool, which targets vulnerabilities disclosed by China’s dominant search engine. DEMO: Live targeting of vulnerabilities in Chinese government websites exposed via Baidu.
  • DroidDiggity – fully functional GoogleDiggity and BingDiggity application for Android phones.
  • GoogleCodeSearchDiggity – identifying vulnerabilities in open source code projects hosted by Google Code, MS CodePlex, SourceForge, and more. The tool comes with over 40 default searches that identify SQL injection, cross-site scripting (XSS), insecure remote and local file includes, hard-coded passwords, and much more.
  • FlashDiggity – automated Google searching/downloading/decompiling/analysis of SWF files to identify Flash vulnerabilities and info disclosures.
  • SHODAN Hacking Alerts – new live vulnerability RSS feeds based on results from the popular SHODAN hacking search engine.
  • MalwareDiggity and MalwareDiggity Alerts – leveraging Bing API and the Google SafeBrowsing API together to provide an answer to a simple question, “Am I being used as a platform to distribute malware to people who visit my website?”
  • AlertDiggity – Windows systray application that filters the results of the various Google/Bing/Shodan Hacking Alerts RSS feeds and notifies the user if any new alerts match a domain belong to them.
  • DiggityDLP – Data loss prevention tool that leverages Google/Bing to identify exposures of sensitive info (e.g. SSNs, credit card numbers, etc.) via common document formats such as .doc, .xls, and .pdf. Also utilizes Google APIs for searching across Google Docs/Spreadsheets for data leaks.

That is just a taste of the new tools that will be explored in this DEMO rich presentation. So come ready to engage us as we re-define Google Hacking once again. WARNING: For safety, you should be in good health and free from high blood pressure, heart, back or neck problems, motion sickness, or other conditions that could be aggravated by this adventure.

Binary Instrumentation of Programs

Presented by: Robert Cohn

Binary instrumentation is a tool for understanding the dynamic behavior of a program by observing its execution with injected code. Security and Privacy researchers use binary instrumentation tools to analyze program and malware behavior. Binary instrumentation makes it possible to detect programs that decrypt them self at runtime and malware that exploits buffer overflow. It can be used to perform taint analysis to track the flow of data through a program. Instrumentation can also help find exploitable bugs like memory use after deallocation and references to uninitialized data. The talk will describe a popular instrumentation tool called Pin and connect it to security/privacy related ideas. The talk would be interesting to people interested in analyzing behavior of native applications and developing their own tools.

Mozilla Secure World: Simple Ways to Secure Your Website

Presented by: HaoQi Li

MozSecWorld is a web security reference site. It can teach you simple ways that you can make your own websites more secure. You'll learn through diagrams, explanations, and best of all, live demos! :) If you are a web developer, you might find the open-source code for each demo helpful too.

OWASP Mobile Top 10 Risks

Presented by: Zach Lanier

This presentation will feature the recently unveiled, official OWASP Mobile Top 10 Risks. As many agree that mobile application security is in its infancy, this list is intended to help developers and organizations prioritize their security efforts throughout the development life cycle. Many of the same mistakes made over the past decade in other areas of application security have managed to resurface in the mobile world. There have also been many new security challenges introduced by mobile applications and platforms. Through the OWASP Mobile Security Project, the primary goal is to enhance the visibility of mobile security risks just as OWASP has successfully done for the web.

As the attack surface and threat landscape for mobile applications continues to rapidly evolve, arming developers with the tools they need to succeed is essential. Each environment presents very unique and different risks to consider. Our research and findings will be presented from a platform agnostic perspective.

The Perils of JavaScript APIs

Presented by: Ming Chow

Client-side development with JavaScript has grown significantly thanks to Ajax, the plethora of JavaScript libraries such as jQuery, and powerful JavaScript engines such as Google's V8. With the rapid push for HTML5 and the emergence of Node.js, JavaScript has become paramount. However, we are starting to move away from the same-domain policy. Currently, the XMLHttpRequest object in the latest versions of Chrome and Firefox now supports cross-domain communications to a degree. HTML5 has also introduced a number of features including WebWorkers, cross-document messaging, and WebSockets that are JavaScript-heavy and have raised a number of security issues. This presentation will also delve into the best practices of rendering and parsing JSON, the security woes surrounding WebGL, and the state of creating and running a Node.js web server

Preventing Data Breaches from Vulnerable Web Applications using Data Provenance

Presented by: Anirudh Ramachandran

Data breaches through Web application vulnerabilities have become particularly rampant. Point solutions -- for example, a Web Application Firewall that scans requests destined to the Web app -- can only stop a limited number of attack patterns, and do not provide any protection from a breach once a vulnerability is eventually exploited. We have been researching a complementary approach to prevent breaches, based on the idea that if sensitive data is tracked closely enough, an organization can prevent breaches without worrying about Web application vulnerabilities that lead to breaches.

We have designed a system, Pedigree, that associates tamper-proof tags with database records and files, and uses an OS-level module to track the flow of tagged data through the various components of a Web application. Pedigree also tags network data, ensuring that a simple firewall or switch can identify the provenance of a flow using the tag on its packets. Thus, the firewall can choose to permit a flow that is a response for an authorized Webapp user request to pass through it, while denying flows that are unauthorized and likely correspond to malicious exfiltration requests (e.g., an SQL injection).

In this talk, I will present the architecture of Pedigree and describe how Pedigree might be integrated with existing Web application frameworks and firewalls.

Reversing Web Applications

Presented by: Andrew Wilson

Information gathering is not only the first step, but perhaps the most important repeated process within penetration testing. How well a tester is capable of learning the characteristics and nuances of an application can make all the difference in comprehensive testing and sophisticated attacks. Information gathering is far more than merely mapping an application.

This talk focuses on common pitfalls and misconceptions of information gathering, and how we can approach it better. Using strategies from reverse engineering and forensics, we will learn the skills and tools needed to find evidence, grok what it means, so that we can ensure ensure consistent & comprehensive understandings of how a site works. Specific things that will be covered include: Anti-patterns, learning behaviors of an application, reading exceptions between the lines, finger printing a website beyond HTTP headers, creating a working API for scripted attacking, and content discovery beyond throwing massive wordlists at the wall.

Tools which support these tasks, and counter measures that make this more challenging will be discussed throughout the talk.

Secrets Of Static Binary Analysis

Presented by: Christien Rioux

Ever wanted to know more about how static binary analysis works? It's complicated. Ever want to know how C++ language elements are automatically transformed? The high-level overview of how machines analyze code for security flaws is just the beginning. In this talk we'll be delving into the gritty details of the modeling process.

Don't Get Pwn3d By Your Phone

Presented by: John Carmichael

With the ever increasing market for smart phones, application developers and consumers are making a mad dash for the mobile application architecture. Much like the race to the web many are ignoring the security lessons previously learned and are creating a new avenue of attack which puts individuals as well as organizations at risk. Focusing on the two major players in this space, Apple iOS and Google Android, this talk will focus on the types of issues common to mobile apps and will provide advice for both smart phone owners as well as application developers on how they can protect the data which is being entrusted to these devices.

There’s an App for That

Presented by: Michael Anderson

Theoretically, the security industry knows that mobile phones are an exposed attack surface. Practically, there has been very little attention paid to the subject. As an introduction, the resources that a mobile phone can provide to a hacker will be explained. These include persistent internet connections (providing an entry point to any physically near network) and a low profile(which assists in evading both physical security). Next, discussion will focus on the construction of the proof of concept: using chroot jails with qemu files compiled for the ARM processor architecture. With the proof of concept model in hand, the presentation will include discussion of practical threat modeling demonstrating the usage of the above benefits. Threats discussed in depth: -a targeted cyber attack/penetration test, leveraging a mobile phone as an entry point -using the phone as part of a less focused campaign to compromise poorly protected personal resources such as laptops or other mobile phones in coffeeshops. To conclude, focus will be placed on further work. Potential opportunities for further research include packaging the qemu files necessary to run an emulated Linux environment as a payload.

WAFs - An Overview of Free Web Application Firewalls

Presented by: Roy Wattanasin

Web application firewalls (WAFs) are an additional security layer that can help protect against 'some' common attacks as from the OWASP top ten security risks list. By customizing the rules to your applications, many attacks can be identified and thwarted. However, this requires significant effort with testing and maintaining application change control. Participants will come away with the basics of web application firewalls, differences, best practices and learn some common characteristics of using them.
