Dynamic Password Hardening
Robert Moskovitch, Ben-Gurion University
Robert would present a project developed at the Deutsche Telekom Laboratories at Ben Gurion University which uses keystrokes dynamics and continuous verification using keystroke and mouse dynamics to harden password and prevent identity theft on the Internet. The presentation will touch on the technique challenges and state of development and would include a demo. Robert is a researcher at the Deutsche Telekom Laboratories at Ben Gurion University
Ofer Shezaf: Prepare Your Car for
Ofer Shezaf, Better Place
Cars are going wired and no one is going to stop it. Many car manufacturers already offer an on board computer that is an integral part of the car and communicates with the world over cellular links. This computer offers navigation, entertainment, phone, location and safety application among others. However this level of connectivity both to the car systems and to the world presents a new threat affecting car users privacy and driving safety. The presentation will discuss new car computing platforms, their security implications and propose mitigation methods.
The Bank Job: A hacker’s day of work - Exploiting a vulnerable web site
Adi Sharabani , IBM
In this presentation we will show how severe a Cross-Site Scripting vulnerabilities are. We will build a step-by-step working exploit code for an XSS vulnerability found in an online banking site to hijack user sessions, transfer money and cover the traces. The money will be shared among the audience.
The presentation does not require any prior knowledge, but it is also aimed for technical people.

Identity management is often driven by operational requirements rather than security requirements. The presentation will explore the security aspects of IdM as part of authentication and authorization. Among the issues discussed are: What security benefits can an IdM provide? What IdM types, techniques and methods best suit security requirements? And lastly what are the security pitfalls and disadvantages of IdM.

ReDoS (Regular Expression Denial of Service) Revisited
Alex Roichman, Checkmarx
The presentation will explore the Regular Expression Denial of Service (ReDoS) attack and how it be used in order to implement new and old attacks. ReDoS is commonly known as a “bug” in systems, but the presentation will show how serious it is and how using this technique, various applications can be “ReDoSed”. These include, among others, Web Application, WAFs, IDS, AV, Web Servers, Client-side browsers (including cellular devices), and Database.

SSSL: Server Side Secure Login to Phish-Protect your website
Ronen Margulis, Bar Ilan University (Joint work with Prof. Amir Herzberg)
SSSL combines two highly efficient mechanisms to defend against phishing attacks. The first mechanism is a specially crafted bookmark which provides two-factor authentication. The second mechanism is an interactive custom image which is presented to the user on each login, and which the user has to click on in order to submit his credentials. SSSL's main advantages are its enhanced security and simple deployment. These two defense mechanisms were proven to be the most efficient mechanisms among different defense mechanisms tested in real life experiments. Furthermore, the two mechanisms complement each other: each protects a different secret, creating a safer login method. SSSL may be most useful in preventing a number of phishing attacks at high-value sites such as banking sites and single sign-on sites such as OpenID providers
Ofer Rotberg, IDC
Cross-site Scripting (XSS) has emerged as one of the most prevalent types of security vulnerabilities in web applications. Current defense mechanisms are mainly based on detecting malicious content on HTTP-requests using a negative security logic approach. This approach has known limitations, derived from the difficulty to define all the HTTP-request payload characteristics that may lead to XSS attacks. In this work we present a positive security logic approach to detect and prevent XSS attacks by verifying that every web-page sent back to the user's browser contains only "legal and original" code scripts inserted into the HTTP-response by the web application without being influenced by malicious input. Our results show that after a short learning period the XSS detector has zero false-positive and zero false-negative given our prototype limitations.
