Welcome to my writeups for picoCTF challenges.
In May 2026 the web site rebranded and is now called CyLab Security Academy.
These writeups are mainly a documentation for myself but I hope others will benefit from them as well.

The solutions contains step-by-step walkthroughs but doesn't display the flags in plain text.
Instead the flags are displayd as picoCTF{<REDACTED>} or with just some portion of the flag visible.
These solutions can be used in two different scenarios:
Scenario #1:
When you are stuck, have already tried different solutions on your own, and don't know how to continue.
Don't look at them to soon though. It's always good to develop your "Try harder"-mindset!
Scenario #2:
When you have already solved the challenge on your own but what to see if you can learn different methods, tools or approaches.
Are there different and perhaps smarter ways to solve the challenge?
