  • Auditing C# Code - Ilja van Sprundel
    In this presentation, Ilja van Sprundel, Principal Consultant at IOActive, will discuss reviewing C# code, specifically C# code used for ASP.NET. He will cover entrypoints, exit points, .NET input validators, corner cases of API's, integer rules, managed vs unmanaged code, the garbage collector, exception handling issues, XSS cases, SQL Injection bugs, XML handling issues and usage of Anti-XSS.
  • The Ultimate IDS Smackdown - How red vs. blue situations can influence more than one might assume - Mario Heiderich and Gareth Heyes
    The talk is a vector and coding showdown between the lead dev of the PHPIDS and one of its most determined challengers trying and managing to break it wherever possible. Expect a bloody battle between security researchers and developers without limits, regular expression magic against code obfuscation excellence leading to an interesting result about vs-situations in software development and IT security.


  • Mario Heiderich - I am Mario Heiderich, cologne based CTO for an online enterprise based in Cologne and New York. I was visitor and speaker on several OWASP conferences, maintain the PHPIDS and other security related projects and recently authored a German book on Web Security together with Christian Matthies, fukami and Johannes Dahse. I am currently into browser security, broken markup, client side attacks and digging the HTML5 specifications.
  • Gareth Heyes - I'm from the UK and I like hacking javascript and XSS filters. I am not a security expert, in fact I'm the anti-security expert. Don't expect statistics from me, I like vectors and interesting code. I authored Hackvertor and many other security related tools.


Please RSVP for this meeting, as space is limited. As mentioned at the last meeting, we're going to trial an event signup system, so please RSVP at Note, please enter your real name, as this will be given to Barclays building security to ensure you are let into the building.

Location: Barclays, Presentation Suite 2, One Churchill Place, London E14 5HP

  • Hash Cookies - A simple recipe - John Fitzpatrick (PDF)
    Hash cookies is a concept devised in concert with a couple of other guys whilst discussing an application test we were working on. The goal of hash cookies being to make session hijacking attempts infeasible through re-hashing the session cookie on future requests to the server.
    The aim of this talk is to put across the concept of hash cookies and then have the audience don their ninja suits and break it. That way we can work towards a robust secure mechanism for securing sessions which, hopefully, hash cookies is a good solid step towards.
  • OWASP Google Hacking Project - Christian Heinrich (PDF (zipped))
    Two Proof of Concepts (PoC) used during the reconnaissance phase of a penetration test will be demonstrated:
    1. "TCP Input Text" extracts TCP Ports and Fully Qualified Domain Names (FQDN) from Google Search Results into a .csv file and individual shell scripts for nmap and netcat to provide assurance of a listening TCP service since the last crawl performed by the "GoogleBot".
    2. "Download Indexed Cache" retrieves content indexed within the Google Cache and supports the "Search Engine Reconnaissance" section of the recently released OWASP Testing Guide v3. During the demonstration of "Download Indexed Cache", the superiority of this approach will be proven over lesser methodologies, such as "Google Hacking" and the associated Google Hacking Database (GHDB).
    The impact of mitigating controls, such as <META> Tags and robots.txt, based on the recommendations within the "Spiders/Robots/Crawlers" section of the recently released OWASP Testing Guide v3, will be explained.

OWASP Global Industry Committee - Colin Watson (PDF)

The Global Industry Committee was one of six new OWASP committees created during the EU Summit in Portugal last year. Colin Watson will talk about the committee's aims, plan, how to get involved, who it has been engaging with and what else it has been doing in the first few months.

The Software Assurance Maturity Model - Introduction and a Use Case - Matt Bartoldus (PDF)

The OWASP CLASP Project has been going through modification to move more towards a maturity model. As a result, the Software Assurance Maturity Model (SAMM) project has been released in a beta version. The goal is to "define a usable security framework with sequential, measurable goals that can be used by small, medium, and large organisations in any line of business that involves software development". This talk will introduce SAMM and give a brief overview of its contents. We will then discuss how SAMM is currently being used to measure the level of information security activities within an EU based financial organisation's development methodology and providing the framework for implementing such activities into their everyday development activities (SDLC).

SQL injection: Not only AND 1=1 - Bernardo Damele A. G. (PDF)

The presentation will cover a quick preamble on SQL injection definition, sqlmap and its key features. It will then illustrate the details of common and uncommon problems and respective solutions with examples that a penetration tester or a SQL injection tool developer faces when he wants to take advantage of any kind of web application SQL injection flaw on real world web applications, for instance SQL injection in ORDER BY and LIMIT clauses, single entry UNION query SQL injection, blind SQL injection algorithm speed enhancements, specific web application technologies IDS bypasses and more.

Justin Clarke: SQL Injection Worms for Fun and Profit (PDF)

Earlier this year the first (publicly known) SQL Injection worm appeared. This worm used SQL Injection to insert malicious scripting tags into the pages of over 90,000 sites that were vulnerable to SQL injection.

Yet the exploit vector was fairly innocuous, easy to clean up, and easy to block. In other words, very much version 0.1 of what a SQL Injection worm can achieve.

This talk is going to discuss how far the rabbit hole can go with SQL injection based worms, including full compromise of the server OS, and why we should be worried by what is going to be coming next out of Russia/China/wherever, including a live demo of a proof of concept SQL injection worm, "weaponized".

Dinis Cruz: OWASP Summit 2008 Report

The OWASP Summit 2008 has been a great success. Dinis, also known as Chief OWASP Evangelist, is going to tell us what we've missed.

Andrew Nairn: Protecting Vulnerable Applications with IIS7 (PDF)

With the advent of IIS7 and its modular design, Microsoft has provided the ability to easily integrate custom ASP.NET HttpModules into the IIS7 request-handling pipeline. This session will present an IIS7 module designed to leverage this architecture to actively and dynamically protect web applications from attack. With minimal configuration, the module can be used to protect virtually any application running on the web server, including non-ASP.NET applications (such as those written in PHP, Cold Fusion, or classic ASP).

This presentation will outline the overall design and architecture of the module, including a detailed explanation of available features and attack defense techniques. The session will focus on live demonstrations of how the module can easily be installed to protect already-deployed applications and how it can block both traditional web application attacks, such as SQL injection and Cross-Site Scripting, and application-specific vulnerabilities like parameter manipulation and authorization attacks.

    • by Dinis Cruz (Chief OWASP Evangelist) :
      • OWASP, the Open Web Application Security Project 30m - The Open Web Application Security Project (OWASP) is an open community dedicated to enabling organizations to develop, purchase, and maintain applications that can be trusted. All of the OWASP tools, documents, blogs, and chapters are free and open to anyone interested in improving application security. In this presentation Dinis will show the latest guides and tools from OWASP which should be part of every company's security efforts.
      • Buffer Overflows on .Net and Asp.Net 30m - One of the common myths about the .Net Framework is that it is immune to Buffer Overflows. Although this might be correct in pure managed and verifiable .Net code, large percentage of .Net and Asp.Net applications code is unmanaged code. In this talk Dinis will show the areas in .Net and Asp.Net applications that are vulnerable to Buffer Overflows (including the demo of a .Net Buffer Overflow Fuzzer).
      • 0wning Vista's userland - The CAS / UAC missed opportunity , and what I think MS should had done - In this presentation Dinis will explore the missed opportunity by Microsoft to use technologies like .Net's CAS (Code Access Security) and Vista's UAC (User Access Control) to create secure and trustworthy userland environments that protect the user's assets. In the hope that might make a small difference, ideas and solutions for the future will also be presented.
