OWASP Global AppSec EU 2026 Vienna

3-Day Training:June 22-24, 2026
Level: Intermediate
Trainer: Dawid Czagan


To register, please purchase your training ticket here. Training and conference are two separate ticket purchases.

Modern IT systems are increasingly complex, making full-stack expertise more essential than ever. That's why diving into full-stack pentesting is crucial—you will gain the skills needed to master modern attack vectors and implement effective defensive countermeasures.

For each attack, vulnerability and technique presented in this training, there is a lab exercise to help you develop your skills step by step. What's more, when the training is over, you can take the complete lab environment home to hack again at your own pace.

I found security bugs in many companies including Google, Yahoo, Mozilla, Twitter and in this training I'll share my experience with you.

Key Learning Objectives
After completing this training, you will have learned about:

- Hacking cloud applications
- API hacking tips & tricks
- Data exfiltration techniques
- OSINT asset discovery tools
- Tricky user impersonation
- Bypassing protection mechanisms
- CLI hacking scripts
- Interesting XSS attacks
- Server-side template injection
- Hacking with Google & GitHub search engines
- Automated SQL injection detection and exploitation
- File read & file upload attacks
- Password cracking in a smart way
- Hacking Git repos
- XML attacks
- NoSQL injection
- HTTP parameter pollution
- Web cache deception attack
- Hacking with wrappers
- Finding metadata with sensitive information
- Hijacking NTLM hashes
- Automated detection of JavaScript libraries with known vulnerabilities
- Extracting passwords
- Hacking Electron applications
- Establishing reverse shell connections
- RCE attacks
- XSS polyglot
- and more …

What Students Will Receive
Students will be handed in a VMware image with a specially prepared lab environment to play with all attacks, vulnerabilities and techniques presented in this training. When the training is over, students can take the complete lab environment home (after signing a non-disclosure agreement) to hack again at their own pace.

Special Bonus
The ticket price includes FREE access to my 6 online courses:

- Fuzzing with Burp Suite Intruder
- Exploiting Race Conditions with OWASP ZAP
- Case Studies of Award-Winning XSS Attacks: Part 1
- Case Studies of Award-Winning XSS Attacks: Part 2
- How Hackers Find SQL Injections in Minutes with Sqlmap
- Web Application Security Testing with Google Hacking

What Students Say About My Trainings
References are attached to my LinkedIn profile (https://www.linkedin.com/in/dawid-czagan-85ba3666/). They can also be found here: https://silesiasecuritylab.com/services/training/#opinions – training participants from companies such as Oracle, Adobe, ESET, ING, Red Hat, Trend Micro, Philips, government sector... 

What Students Should Know
To get the most of this training intermediate knowledge of web application security is needed. Students should have experience in using a proxy, such as Burp Suite Proxy or Zed Attack Proxy (ZAP), to analyze or modify the traffic.

What Students Should Bring
Students will need a laptop with 64-bit operating system, at least 8 GB RAM, 35 GB free hard drive space, administrative access, ability to turn off AV/firewall and VMware Player/Fusion installed (64-bit version). Prior to the training, make sure there are no problems with running x86_64 VMs.

Additional notes
This new 3-day training was sold out at top security conferences e.g. DEF CON (Las Vegas), Hack In Paris (Paris).

This is a 100% hands-on training: for each attack, vulnerability and technique presented in this training, there is a lab exercise to help students develop their skills step by step.
