Agenda

13:30-14:00 Gathering

14:00-14:10 Opening words, Ofer Shezaf, OWASP Israel chapter lead

14:10-14:40 Identity Theft, Computers and Behavioral Biometrics

Robert Moskovitch, Deutsche Telekom Laboratories at Ben-Gurion University

Identity Theft is a fraud, in which someone pretends to be someone else is order to steal money or get other benefits. To overcome the problem of Identity Theft an additional security layer relying on the verification of users, based on their keystroke dynamics is proposed. Additionally we suggest to continuously verify users based on their keystrokes and mouse dynamics. The motivation for such technology, its challenges and potential, will be discussed.

Robert Moskovitch is a Project Manager at the Deutsche Telekom Laboratories at Ben Gurion University.

14:40-15:30 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.

Adi is a security research group manager for IBM labs

15:30-16:00 IdM: the missing security link

Avi Douglen

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.

Avi is an independent security architect

16:20 - 17:00 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.

17:00 - 17:40 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

17:40 - 18:20 A New Approach to XSS Detection using JavaScript modeling

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.
