Training, December 1st

OWASP Training: Secure Application Development, by Eoin Keary

Abstract: Writing Secure code is the most effective method to securing your web applications. Writing secure code takes skill and know-how but results in a more stable and robust application and assists in protecting an organisations brand. Application security is not commonly a part of many computer science curricula today and most organizations have not focused on instituting a culture that includes application security as a core part of their software development training efforts. This intensive one-day course focuses on the most common web application security problems, including aspects of both the OWASP Top Ten (2010) and the MITRE Top 25. The course will introduce and demonstrate application assessment techniques, illustrating how application vulnerabilities can be exploited so students really understand how to avoid introducing such vulnerabilities in their code.

This course includes coverage of the following areas:

  • Unvalidated Input
  • Injection Flaws, OS commanding, SQL Injection
  • Cross-Site Scriping & Client-side security
  • Authentication & Session Management
  • Access control & Authorisation
  • Broken Caching
  • Error Handling & Resource Management
  • The Secure SDLC
  • Fuzzing, Proxy use and testing approach

Hands on Exercises

To cement the principles discussed, students can participate in a number of hands-on security testing exercises where they attack a live web application (i.e., OWASP Bank etc) that has been seeded with common web application vulnerabilities.

The students will use proxy tools commonly used by the hacker community to complete the exercises. Students need to bring their own windows based laptop to participate in the exercises. Wireless capability is recommended.


Developers who want to understand the most common web application security flaws, and how to avoid them and code in a secure manner.

Level: Beginner/Intermediate

Prerequisite: Basic knowledge of a web programming language like Java or .NET recommended but not required.

Bringing your own windows based laptop is recommended so you can participate in the hands on exercises

Stay tuned for the final agenda!

Agenda will come here

OWASP SIMBA - guarding your applications (by Koen Vanderloock, Leader Security Competence Group at Cegeka)

SIMBA (Security Integration Module for Business Applications) is a OWASP project that provides you with a User Access Management system that can be integrated with any business application. The purpose of SIMBA is to secure an application fast and easy. Because SIMBA itself is generic it can be customized for every project. Many features are customizable e.g. designing your own authentication chain is easy and fast by using existing or newly created building blocks. SIMBA contains authentication, authorization, session management and a GUI to manage your security information.

Koen Vanderloock, Leader Security Competence Group at Cegeka

Koen Vanderloock is the leader of the security competence group at Cegeka. About 2 years ago Cegeka decided to create a sandbox for investigating security issues and solutions so they could be included in the current projects. Koen Vanderloock is a Java developer with 8 years of experience and started exploring the world of security 3 years ago when UAM problems started to occur.

Practical Crypto Attacks Against Web Applications (by Justin Clarke, Director and Co-Founder of Gotham Digital Science Ltd)

The science of cryptography underpins many of the information security technologies we use on a daily basis, such as the ability to keep information confidential and to ensure we can identify who we are communicating with. However, it is a very complex subject area with many types of mistakes that can reduce the overall security of a solution. A number of these types of mistakes can be identified by a tester, if they know what they're looking for, but in general it isn't a well tested area.

This talk is intended to provide a high level overview of some of the areas where cryptographic operations such as encryption and hashing can provide far less security than was planned, and concrete examples of how these were found and exploited. Examples will include discussion and demonstration of the recently patched cryptographic padding attack against the Microsoft .NET framework (affecting ASP.NET applications) caused by a design error in how ASP.NET handles some types of encrypted data, but we will also be looking at some other fun areas including bit flipping attacks, ECB mode attacks, and some miscellaneous hashing algorithm attacks against common web application implementations.

Justin Clarke, Director and Co-Founder of Gotham Digital Science Ltd

Justin is a Director and Co-Founder of Gotham Digital Science and an experienced software security consultant with extensive international Big 4 risk management, security consulting and testing experience. He is the lead author/technical editor of "SQL Injection Attacks and Defenses" (Syngress 2009), co-author of "Network Security Tools" (O'Reilly 2005), contributor to "Network Security Assessment, 2nd Edition" (O'Reilly 2007), as well as a speaker at various security conferences and events such as Black Hat, EuSecWest, ISACA, BruCON, OWASP, OSCON, RSA and SANS. He is currently the OWASP London chapter president, and a member of the OWASP Global Connections Committee. On 10 Oct 2011, at 09:33, Seba wrote:

HTML5 security (by Lieven Desmet, Research Manager at Katholieke Universiteit Leuven)

In this talk, Lieven will highlight the results of the HTML5 security analysis, conducted by the DistriNet Research Group (K.U.Leuven). The security analysis of next generation web standards, commissioned by ENISA, looked into 13 emerging W3C web standards (i.e. the specification of HTML 5 and some of the associated APIs), and assessed the security of each of them as well as the overall security and consistency across specifications.

In total 51 security threats and issues have been identified, and detailed in the ENISA report ( During the talk, Lieven will discuss the methodology developed to assess the huge amount of specifications, and zoom into a representative set of identified threats and their remediation.

Lieven Desmet, Research Manager at Katholieke Universiteit Leuven

Lieven Desmet is the Research Manager on Secure Software at the Katholieke Universiteit Leuven (Belgium), where he coaches junior researchers in web application security and participates in dissemination and valorization activities.

Overcoming iOS Data Protection to Re-Enable iPhone Forensics (by Andrey Belenko, Chief Security Researcher at ElcomSoft)

Data protection is a feature available for iOS devices (iOS 4 and up) with hardware encryption: iPhone 4S, iPhone 4, iPhone 3GS, iPod touch (3rd generation or later), and all iPad models. Introduction of this feature had complicated iPhone forensics process because now (almost) all files on user partition are encrypted and physical dumps are of much less value to examiners: while the filesystem seems to be intact, actual file contents are encrypted and are not suitable for analysis.

This talk will provide in-depth information about iOS Data protection internals and on the implication it had on iOS forensics. More specifically, it will cover the following:

  • System keys and their hierarchy
  • Device passcode and its recovery
  • Escrow keys
  • Filesystem encryption
  • Keychain encryption

Presentation will start by providing attendees with required background on iOS encryption keys architecture: system keys, passcode key, escrow key. After attendees are familiar with those concepts, presentation will continue to filesystem and keychain encryption details and to the techniques that can be used to overcome the hurdles imposed by iOS Data Protection.

Do you... Legal? (by Ludovic Petit, Group Fraud & Information Security Adviser at SFR, Vodafone Group)

The OWASP core mission is to make application security visible, so that people and organizations can make informed decisions about true application security risks. However, if you do not pay enough attention to many aspects of Legal compliance, you'll see why Web Application Security is somehow linked to Legal and Regulatory aspects as well as... Corporate Responsability, so yours. Who is accountable for what, what about each other's responsibility? Nowadays, the legal constraints oblige us to comply via technical means, whatever the local framework, and this is specially true for Web Application Security, many sensitive informations having to be handled through these web interfaces. A such, what do you think about your Security Policy compliance with your local Legal framework? Compliant? Sure? Really? Interesting isn't it? Let's have a talk about this.

Ludovic Petit, Group Fraud & Information Security Adviser at SFR, Vodafone Group

Ludovic is an internationally recognised information security expert with over 25 years experience. Last 15 years spent in various Corporate Management positions covering both Technical and Law Enforcement expertise dedicated to Mobile Telecommunications Fraud and Security in multi-national corporations.

eBanking vs. Malwares (by Jean-Marc Bost and Sébastien Bischof, ECLA)

The swiss german TV channel SF1 showed a footage on swiss e-banking security. The TV show follows a team of the ETH who earned a special authorization to test several e-anking platforms. After admitting that a personal computer can be infected by different means (actually 5% of the tested PCs are infected according to Microsoft), The team from Zürich showed the limits of the different platforms. Only the bank who signs each transaction is labelled as safe. We will come back during the presentation on the nature of the threat.
First of all, we will explain how famous malwares such as Zeus and SpyEye manage to steal from their victims without them being able to notice anything. Then we will see that e-banking is not the only target, as a matter of fact, the reality is far from this.
And then we will comment the most recent techniques that allow malwares to escape Antivirus and Antimalware programs even if they are up to date. We will vulgarize several concepts such as DKOM and bootkits in order to let everybody have a glimpse on the danger they represent.
Finally, we will think about if signing each transaction can efficiently fight off these threats. In fact, when attacks are coupled with Social Engineering, they have potentially no limit. Zeus is a living proof of this fact, because it even managed to attack the transaction validation system by SMS. As a conclusion, we will see that the e-banking platform that managed to resist the tests of the ETH team is vulnerable to such kind of attacks.
