Bot Extension - Abusing Google Chrome Extensions for Bot Attacks
תוספי בוט - שימוש בתוספי כרום למטרת התקפות בוטים

 Tomer Cohen, Head of R&D security, Wix.com 

Chrome extensions have opened a variety of opportunities for users as well as developers, expanding the limits of what we've known as browsing experience. Attacker have also spotted the wide usage of such extensions, and abuse people's trust in Chrome Web Store to distribute malicious extensions. This allows them to run web-based bot attacks straight from victims' browsers, including DDoS campaigns and cross-site requests resulting in impersonation of users in third-party websites.

Furthermore, the detection of such bot attack by a third-party is more complex than in regular distributed attacks, since real humans actually use the Chrome tab abused to attack the victim third-party.

The lecture will include an intro on Chrome Extension architecture followed by techniques to abuse this architecture in order to run bot attacks, as well as distribute a malicious extensions to big crowds of victims.

Could a few lines of code  it all up!
 Amit Ashbel, Director of Product Marketing & Cyber Security Evangelist, Checkmarx 

March 2016. An anonymous open source developer decides to remove his code (left-pad) from a public repository.

Shortly thereafter, several large organizations felt the impact of his actions. Facebook, AirBnB and others experienced errors impacting the functionality of their services. Packages using “left-pad” wouldn’t properly execute.

Today, we embrace both the open source community and the growth of open source projects, modules and packages but... Dependencies and recursive dependencies might become a risk or even a new attack vector which we didn’t foresee.

Could there be other cases of common and popular open source packages depending on open source modules that might not be there tomorrow or, even worse, could they be maliciously modified?

Join us for an insightful session that will reveal our research on this topic where you will learn:
 * Which common open source packages might not be there tomorrow and how this can affect you?
 * How packages you use could be maliciously modified impact on your app Discuss the risks introduced by hybrid application development
 * How intertwined and complex dependencies have become

Crippling HTTPS with unholy PAC
איך להרוס HTTPS עם PAC"ל חבלה

 Amit Klein, VP Security Research, SafeBreach 

You're in a potentially malicious network (free WiFi, guest network, or maybe your own corporate LAN). You're a security conscious netizen so you restrict yourself to HTTPS (browsing to HSTS sites and/or using a "Force TLS/SSL" browser extension). All your traffic is protected from the first byte. Or is it?

We will demonstrate that, by forcing your browser/system to use a malicious PAC (Proxy AutoConfiguration) resource, it is possible to leak HTTPS URLs. We will explain how this affects the privacy of the user and how credentials/sessions can be stolen. We will present the concept of "PAC Malware" (a malware which is implemented only as JavaScript logic in a PAC resource) that features: a 2-way communication channel between the PAC malware and an external server, contextual phishing via messages, denial-of-service options, and sensitive data extraction from URI's. We present a comprehensive browser PAC feature matrix and elaborate more about this cross-platform (Linux, Windows, Mac) and cross-browser (IE, Chrome, Safari) threat.

Don't Feed the Hippos!
 Martin Knobloch, Principal Consultant, Nixu 

The security community is trying to solve insecurity caused by bugs and flaws in software for many years now, but with what success?

We almost never look in successes and failures experiences in other areas, but we could really learn from. This talk is inspired by Ernesto Sirolli’s TED talk “Want to help someone? Shut up and listen!” about failures in the aid program’s around the world. Listening to Ernesto Sirolli, you cannot miss the similarity with the security community trying to tell developers how to write secure code. This talk points out common failures of the security community when communicating with developers, trying to solve their problems without understanding what their problems really are.

Using the hippo-analogy for security failures, during the talks those ‘(in-)secure hippos’ are identified, advice on how to avoid them are provided, by anecdotes and best practices from the experience of the past 10 years in the security field as a consultant.

Hacking HTTP/2 - New attacks on the Internet’s Next Generation Foundation
 Nadav Avital, Application Security Research Team Leader, Imperva 

 Noam Mazor, Security Research Engineer, Imperva 

HTTP/2 is the emerging network protocol for the Internet, facilitating leaner and faster web browsing by introducing several new mechanisms which can be seen as a single transition layer for web traffic. The adoption of HTTP/2 is lightning fast, and even though only a year has passed since its publication, HTTP/2 is already supported by all significant players in the field including browsers, web servers and Content Delivery Networks.

In the presentation we will overview the HTTP/2 attack surface - stream multiplexing, flow control, HPACK compression and server push, with a focus on how the way HTTP/2 servers implement these mechanisms can make or break your security posture. We will continue with presenting new classes of vulnerabilities that have been introduced by the mechanisms used with HTTP/2, and explaining how these vulnerabilities can be used for mounting effective attacks against web servers like Apache, IIS, Ngnix, Jetty and nghttp. We will explain in detail several serious zero-day vulnerabilities, such as CVE-2016-1546, CVE-2016-0150 and CVE-2016-1544, and end with discussing several approaches for mitigating attacks of these types.

Those attending this session will understand that:
 * As an emerging technology that introduces novel and flexible mechanisms, HTTP/2 also induces new risks.
 * HTTP/2 implementations are still not “security mature.” Therefore it is almost certain that scrutiny of HTTP/2 implementations will increase in coming years, resulting in the discovery of new vulnerabilities, exploits and security patches. With HTTP/2 gaining more popularity, this trend will intensify.
 * An effective security strategy for newly adopted technologies must rely on supplemental solutions rather than patching

Hacking RF based IoT Systems
האקינג של מערכות IoT מבוססות RF

 Erez Metula, Application Security Expert, AppSec Labs (Founder) 

We often encounter IoT (Internet of Things) systems during our work as penetration testers and security consultants. We know how to assess the security of the server side API, the associated mobile apps, the web apps and so on - but what about the device itself (the "thing")? Moreover, what happens if the device is not using traditional HTTP/S request, or does not even "speak" plain old TCP/IP?

During this talk, we'll go over the obstacles we have to face when analyzing unknown, custom RF based communication that drives the target IoT system we're pentesting. We'll talk about and see in action tools that will allow us to capture RF traffic, analyze it, brute force it, replay it, and of course forge it. It's like plain old appsec hacking tricks, but at the RF level. So let's hack some physical things belonging to the real world!

Putting the "I" in Code Review - Turning Code Review Interactive
 Tamir Shavro,	Seeker R&D Manager, Synopsys 

Everybody knows that manual code review can be a tedious and lengthy effort, with complexity growing exponentially with the size of the code. However, understanding code flow and focusing on relevant parts can become much easier when employing interactive debugging techniques. This allows combining the best of penetration testing and code review benefits to achieve maximum results in the most efficient manner. In this talk we will explain and demonstrate this eye-opening technique for effectively performing a manual code review on a live system using a debugger and provide a quick starter kit for implementing this technique.

The Dark Side of Search Engines Optimizations
הצד האפל של קידום אתרים במנועי חיפוש

 Or Katz, Principal Security Researcher, Akamai 

Search engines optimization (SEO) is a technique being used by web sites owners in order to improve visibility and traffic to their web site. Legitimate SEO activity will use optimization techniques such as: changing structure and textual usage of the web site pages, publication in social media and web forums that will referrer relevant users.

The ultimate goal of SEO campaign is to promote web site ranking in the leading search engines, having the promoted web site returned in the primary result page once searching for relevant terms and keywords.

In the presentation I’m going to present what happens when threat actors get into the world of SEO campaigns abuse SEO optimization techniques and moreover, use all kind of attack techniques such as SQL injection and open redirects in order to manipulate search engines ranking.

I will also evaluate some of the SEO attacks and the manipulating techniques, try to determine who are the victims in this story, check if these attacks achieved their goal and supply more interesting insights on the world of “Blackhat SEO”.

The Threat of Advanced Cross-Site Search Attacks
האיום של התקפות Cross-Site Search מתקדמות

 Dr. Nethanel Gelernter, Cyberpion & The College of Management Academic Studies 

Cross-site search (XS-search) is a practical timing side-channel attack that allows the extraction of sensitive information from web-services. The attack exploits inflation techniques to efficiently distinguish between search requests that yield results and requests that do not. This work focuses on the response inflation technique that increases the size of the response; as the difference in the sizes of the responses increases, it becomes easier to distinguish between them. We begin with browser-based XS-search attack and demonstrate its use in extracting users' private data from Gmail and Facebook. The browser-based XS-search attack exploits the differences in the sizes of HTTP responses, and works even when significant inflation of the response is impossible. This part also involves algorithmic improvements compared to previous work. When there is no leakage of information via the timing side channel it is possible to use second-order (SO) XS-search, a novel type of attack that allows the attacker to significantly increase the difference in the sizes of the responses by planting maliciously crafted record into the storage. SO XS-search attacks can be used to extract sensitive information such as email content of Gmail and Yahoo! users, and search history of Bing users.

Speaker Bio

The Unwanted Sons - Formalizing and Demonstrating WAF Bypass Methods for the REST of the Top 10
צאצאים לא רצויים - פירמול לטכניקות חדשות למעקף WAF לשאר ההתקפות הנפוצות של OWASP TOP 10

 Shay Chen, CEO, Effective Security 

The once uncommon application-level protection mechanisms are EVERYWHERE these days, and sooner or later, you'll have to face them.

Web Application Firewalls (WAF) and Intrusion Detection Systems (IDS), Filters and RASP Modules, all common and widespread countermeasures you have to face on a regular basis, with the power to turn a typical assessment into a nightmare, and make automated tools practically useless.

While the attack vectors are well covered in CWE, CAPEC, TECAPI RvR, WASC, OWASP Top 10 and Testing Guide, all you have to cover evasion techniques is a couple of cheat sheets focused on a limited set of attacks.

Sure, there are numerous XSS and SQL Injection evasion cheat sheets, but what about Path Traversal, Remote File Inclusion, OS Command Injection? What about Forced Browsing? What about other attacks?

Formalizing evasion techniques and methods for the REST of the common attack vectors makes a LOT of sense, for manual pen-testing and automated tools - and THIS is phase one, aimed to cover the rest of the unattended top 10.

Speaker Bio

The Ways Hackers Are Taking To Win The Mobile Malware Battle
 Yair Amit, CTO & Co-founder, Skycure 

In the proverbial game of cat-and-mouse between endpoint security vendors and malware writers, malware attacks have recently grown more sophisticated. More enterprises are losing ground to hackers, who are able to outmaneuver static and runtime solutions by constantly changing their attack strategies. The team that uncovered iOS malicious profiles, WiFiGate, HTTP Request Hijacking, No iOS Zone and Invisible Profiles are taking it upon themselves to coach developers and organizations on how to regain control, and turn the tables on the hackers behind next-generation mobile malware.

In his presentation, Yair will discuss cutting-edge techniques used by malware writers to circumvent mobile security paradigms such as app-sandboxing and containers. Mr. Amit will then break down the current set of techniques (signatures, static analysis & dynamic analysis) used to identify malware on mobile devices, and identify the pros and cons of these approaches. He will also explain why attackers constantly succeed in fooling these technologies, and explore the problem of false positive/false negative tradeoffs in such solutions.

During a live, interactive demo, Yair will create a mobile malware on stage, meant to be undetected by static and runtime analysis technologies.
