Have you heard of OWASP Juice Shop? It's a project that's very dear to me and helped me massively over the last years.
Johannes Seitz was the first one who introduced me to this intentionally vulnerable application used to practice security testing hands-on. He facilitated an open space session at TestBash Munich 2017 with it, and I got hooked. Dan Billing also used this great application in his tutorial at Agile Testing Days 2018. I personally used Juice Shop for security testing workshops at my own company since beginning of 2019.
What I like about Juice Shop is that it's a full-blown application. It's working, and it's vulnerable. We can safely practice lots of techniques, whether manually or having automation support us. You're also not alone, it offers guidance in case you need it. What I love most of all: it's based on gamification, offering many challenges on various difficulty levels. The first challenge itself is to find the score board to get an overview on which tasks are there and what's your progress! Although I know that attackers would approach a productive application differently, the gamification approach is very appealing to me. It's simply fun and draws me further from one challenge to the next.
This kind of gamification also worked well for the people I've had in my workshops, introducing them to security testing. Challenges can be taking time and be quite frustrating - yet when you finally solve them, the moment of epiphany and heureka is invaluable and very memorable. In these workshops, I've also seen people learn how to make more use of tools when testing, like the browser's developer tools or REST clients. Despite them having used these tools before, Juice Shop triggered them to discover more possibilities and features they weren't aware of yet. Also, people shared lots of knowledge on how applications are built, which assumptions we make, which approaches we take.
My personal challenge this year is to tell #SecurityStories, so I thought of using Juice Shop again for teaching. Parveen Khan is currently on a testing tour and asked me to join her for a session. She knew about my #SecurityStories challenge, so we thought it's a great match to pair on security testing. Once more, Juice Shop it was.
I believe that pairing on Juice Shop challenges (or the like) will result in deepening my own understanding by sharing the concepts and approaches I've learned.I know I'll have succeeded when my pair learned 3 new things from me.
Just around that time, a new shiny Juice Shop version got released! Perfect. In our pairing session, I helped Parveen set everything up and we also tackled the first challenges together. As I already knew the solutions, I held back with my knowledge not to spoil the experience for her. Instead, I led her through only nudging in certain directions, waiting for her to ask for hints. It worked! The first challenge was the hardest - it's a whole new application to get to know after all. Once getting the grips with Juice Shop, Parveen solved the second chosen challenge a lot faster. It was really fun doing this together with her! At the end, Parveen shared with me what she learned from this experience hat was completely new to her.
- She knew how to look at information in the browser's developer tools, yet now she learned that she can also do something with it and how powerful these tools really are.
- She always thought that security testing needs a hacker mindset and JavaScript knowledge and therefore concluded that she can't do that. Now she saw she can take first steps into security testing herself indeed and solve challenges to learn more.
- She shared she never had much interest to learn about security, despite knowing that it's important. After having fun with Juice Shop, she's now open to learn more.
- She learned that she could do security testing together with another person to have more eyes on the problem which makes things easier and more interesting.
- She realized she forced herself to think in a different way, and she will always remember that. It was great to get through the experience without me giving away too much.
So I'd say, my experiment worked out well! This experience taught me once more how useful Juice Shop and security testing in general is to teach knowledge that also helps us in everyday testing life: understanding how applications work, what we need to check for under the hood of a shiny interface, which tools can help us, and more. Security testing is combining so much knowledge, learning about it is super useful for anyone involved in product development. This fit very nicely to my findings from doing security testing workshops at my company.
Finally,I had a session with @lisihocke on my #TestingTour.I attended Lisi's talk about her #TestingTour in 2019 & paired on her #CodeConfident challenge and today got chance to pair with Lisi again on my #TestingTour🤩.We solved 2 challenges on OwaspJuiceShop.Thank you so much

I could have stopped there when it comes to Juice Shop. However, there's something that bugged me. Despite knowing Juice Shop for quite a while, and frequently using it for teaching purpose, I haven't solved nearly as many challenges myself as I would like to. I decided that now's the time to change this. So here's my next experiment.
I believe that working on Juice Shop challenges, alone or with a pair, will result in increased confidence in my own skills.I know I'll have succeeded when I've solved all challenges below 5 stars.
This fits well to what I learned during the AppSecDays: I need more hands-on practice. Off to new frontiers! Want to pair with me on this one? Feel free to reach out.
