WebGoat - Teaching application security 101 by Nanne Baars


  • Web Application Breaker
  • Other


WebGoat application, security teaching secure development


A good defense against insecure code requires understanding the mechanics behind how attackers exploit simple programming mistakes. The WebGoat team will walk through exercises like SQL Injection, XSS, XXE, CSRF, ... and demonstrate how these exploits work.

We will show you how you can use WebGoat to train your developers to avoid these simple but common programming mistakes.

We also show you how to extend WebGoat to create lessons specific to your environment. Join us to learn the most basic, but common, application security problems.

Tired of all the lessons? During the training we will host a small CTF competition which you can take a shot at and compete with each other...


Please find the course prerequisites here:


Nanne Baars works as a security consultant & developer at JDriven and is one of the primary developers of WebGoat.

Whiteboard Hacking aka Hands-on Threat Modeling by Sebastien Deleersnyder


  • Threat modeling introduction
  • Diagrams – what are you building?
  • Identifying threats – what can go wrong?
  • Hands-on: STRIDE analysis of an Internet of Things (IoT) deployment with an on premise gateway and secure update service
  • Addressing each threats
  • Hands-on: threat mitigations OAuth scenarios for web and mobile applications


Threat Modeling, STRIDE, Technical risk assessment


This is a one day version of our Black Hat training on Threat Modeling. The students will be challenged to perform practical threat modeling in groups of 3 to 4 people covering the different stages of threat modeling on:

  • An Internet of Things (IoT) deployment with an on premise gateway and secure update service
  • An HR services OAuth scenario for mobile and web applications

Threat modeling is a structured activity for identifying and evaluating application threats and vulnerabilities. It also allows consideration of security issues at the component or application level. The threat modeling course will teach you to perform threat modeling through a series of workshops, where our trainer will guide you through the different stages of a practical threat model.
This course is aimed at software developers, architects, system managers or security professionals. Before attending this course, students should be familiar with basic knowledge of web and mobile Applications, databases & Single sign on (SSO) principles.

Secure Development: Models and best practices by Bart De Win


  • Software Assurance maturity models
  • Secure Development in agile development
  • Tips and tricks for practical SDLC
  • Hands-on: SAMM analysis of your enterprise using SAMM 1.5
  • Sneak preview of SAMM 2.0


SDLC, SAMM, Agile development,


It takes much more than a good developer to build secure software within an organisation. Indeed, building secure software is about ensuring that security is taken into consideration during the entire software lifecycle. It is about ensuring that security best practices are being employed efficiently, and that uncovered risks are appropriately dealt with in due time.

During this one-day training, we will introduce and discuss different secure development approaches and models. We will look into waterfall vs. agile development and discuss different strategies to successfully run an SDLC program. Finally, we will also put theorie into practice and take your organisation to perform a mini SDLC assessment and improvement exercise.

Attribute Based Access Control. Why, what, how? by Jacoba Sieders


Digitization is rapidly transforming the traditional world and regulation on security and data protection is gaining weight. Digital identity, but also data protection become crucial capabilities for businesses. What are the trends in IAM and what role can Attribute Based Access Control (ABAC) play here? ABNAMRO started implementing ABAC in 2014. What were the approach and the lessons learnt?


Jacoba Sieders, Head of Digital Identity- & Access, ABNAMRO Bank.
Jacoba is an all-round Digital Identity and Information Security expert with 17 years of experience in the international finance industry, in technology, governance, consultancy, and implementation. She is accountable for digital identity services and access control for customers, employees and partners to the bank’s data and infrastructure. Major topics on her agenda today are ABAC, data centric security, API-banking and PSDII requirements, the interaction of IAM tools with the rest of the bank’s cybersecurity landscape, and the new authentication concept for which ABNAMRO is acquiring a patent. Her special interests are legal requirements impacting identity, e.g. Generic Data Protection Regulation, the EU e-IDAS scheme, KYC and AML legislation. Jacoba is a member of the Advisory Board of the independent European think-tank ID Next and is regularly speaking on the topic of IAM. She holds a master degree in Classics from Leiden University (Greek, Latin, Hebrew).

How to spend $3.6mil on one coding mistake, and other fun stuff you can do with $3.6mil by Matias Madou


In a recent global study, the average cost of a data breach is $3.62M globally. This session will discuss infamous examples of data breaches that has made headlines around the world. We will explore the technical details of the vulnerability itself and what a coding solution may have been to prevent the breach. We will also dive deeper on exploring different solutions, processes and techniques you can apply in your day-to-day to prevent application security vulnerabilities in your code.

The evil friend in your browser by Achim D. Brucker


On the one hand, browser extensions, e.g., for Chrome, are very useful, as they extend web browsers with additional functionality (e.g., blocking ads). On the other hand, they are the most dangerous code that runs in your browsers: extension can read and modify both the content displayed in the browser. As they also can communicate with any web-site or web-service, they can report both data and metadata to external parties.

The current security model for browser extensions seems to be inadequate for expressing the security or privacy needs of browser users. Consequently, browser extensions are a "juice target" for attackers targeting web users.

We present results of analysing over 60000 browser extensions on how they use the current security model and discuss examples of extensions that are potentially of high risk. Based on the results of our analysis of real world browser extensions as well as our own threat model, we discuss the limitations of the current security model form a user perspective. need of browser users.

Exploring the ecosystem of malicious domain registrations in the .eu TLD by Lieven Desmet


In this talk, we report on an extensive analysis of 14 months of domain registration in the .eu TLD. The purpose is to identify large-scale malicious campaigns. Overall, the dataset of this study contains 824,121 new domain registrations; 2.53% of which have been flagged as malicious by blacklisting services. We explore the ecosystem and modus operandi of elaborate cybercriminal entities that recurrently register large amounts of domains for one-shot, malicious use. Although these malicious domains are short-lived, we establish that at least 80.04% of them can be framed in to 20 larger campaigns with varying duration and intensity. We further report on insights in the operational aspects of this business and observe, amongst other findings, that their processes are only partially automated.


Lieven Desmet is a Senior Research Manager on Secure Software in the imec-DistriNet Research Group at the Katholieke Universiteit Leuven (Belgium), where he outlines and implements the research strategy, coaches junior researchers in application security, and participates in dissemination, valorisation and spin-off activities.

Don't trust the DOM: Bypassing XSS mitigations via script gadgets by Sebastian Lekies


Cross-Site Scripting is a constant problem of the Web platform. Over the years many techniques have been introduced to prevent or mitigate XSS. Most of these techniques, thereby, focus on script tags and event handlers. HTML sanitizers, for example, aim at removing potentially dangerous tags and attributes. Another example is the Content Security Policy, which forbids inline event handlers and aims at white listing of legitimate scripts.

In this talk, we present a novel Web hacking technique that enables an attacker to circumvent most XSS mitigations. In order to do so, the attacker abuses so-called script gadgets. A script gadget Is a legitimate piece of JavaScript in a page that reads elements from the DOM via selectors and processes them in a way that results in script execution. To abuse a script gadget, the attacker injects a benign looking element into the page that matches the gadget's selector. Subsequently, the gadget selects the benign-looking element and executes attacker-controlled scripts. As the initially injected element is benign it passes HTML sanitizers and security policies. The XSS only surfaces when the gadget mistakenly elevates the privileges of the element.

In this talk, we will demonstrate that these gadgets are present in almost all modern JavaScript libraries, APIs and applications. We will present several case studies and real-world examples that demonstrate that many mitigation techniques are not suited for modern applications. As a result, we argue that the Web should start focusing more on preventive mechanisms instead of mitigations.


Sebastian Lekies is tech leading the Web application security scanning team at Google. Before joining Google, he was part of SAP's Security Research team, where he conducted academic research in the area of client-side Web application security.

A Series of Unfortunate Events: Where Malware Meets Murphy by Mattijs van Ommeren


When an end user reports some “strange looking file names”, which, after investigating, you discover include several hundreds of Gigabytes of encrypted data, you of course know you are going to have a bad day. Your AV solution has failed you, your firewall has failed you, and your SIEM has failed you. Basically, every piece of security infrastructure you have put your trust (and money) into has left you out in the cold and you thank <deity of choice> that at least the nightly backup was completed successfully. Spin up the tape drive, and soon you will be back in business, or not…?

This talk is about failure. Not only about a failing security infrastructure, but also about failure in doing the Right Thing™ as a first responder, about the failure of Operating System tools, failing APIs, and ironically, also the failure of malware (which is unfortunately not as positive as it may sound). The scenario presented comes pretty close to the worst chain of events you can imagine, in an attempt to recover from a ransomware incident.

Luckily – this story has a happy ending. We will reveal how one can be prepared for when both Count Olaf and Murphy come knocking on your door simultaneously.


Mattijs van Ommeren has been poking hardware and software for 15 years. He has spent most of his working life as a security consultant, attacking and defending both traditional IT environments as well as more esoteric embedded devices and industrial systems. Presently he has a lot of fun at Nixu.

Common REST API security pitfalls by Philippe De Ryck


The shift towards a REST API landscape indicates a significant evolution in the way we build applications. The rise of JavaScript and mobile applications have sparked an explosion of easily-accessible REST APIs. But how do you protect access to your API? Which security aspects are no longer relevant? Which security features are an absolutely must-have, and which additional security measures do you need to take into account?

These are hard questions, as evidenced by the deployment of numerous insecure REST APIs. Attend this session to find out about common API security pitfalls, that often result in compromised user accounts and unauthorized access to your data. We expose the problem that lies at the root of each of these pitfalls, and offer actionable advice to address these security problems. After this session, you will know how to assess the security of your APIs, and the best practices to improve them towards the future.


Philippe De Ryck is a professional speaker and trainer on software security and web security. Since he obtained his PhD at the imec-DistriNet research group (KU Leuven, Belgium), he has been running the group's Web Security Training program, which ensures a sustainable knowledge transfer of the group’s security expertise towards practitioners.

Creating An AppSec Pipeline With Containers In A Week How We Failed And Succeeded by Jeroen Willemsen


Join us on our adventure of setting up a appsec pipeline with Docker containers. What did go wrong, how did we succeed? How do you fight false positives and how do you get the best out of the products out there without bothering the development teams too much.
