Hands-on web security, 2026-04-09, 12:00
A "Capture the Flag" (#CTF) is an ethical game for learning and practising #computersecurity skills in a legal environment. We will play #OverTheWire Natas, which teaches web application security. To solve each level, you need to find vulnerabilities by inspecting the website's source code, HTTP headers, or cookies, finding hidden directories, injecting SQL code, and more.
Open for all, no registration needed.

"We will play the OverTheWire Bandit game" - excellent choice! 🙂

Hello, again 
On weekends, I focus on practicing what I learned during the week. Today, I worked on level 26 of Bandit from OverTheWire.org. It was a doozy level. I didn't know that changing the terminal size could affect the more utility, but I finally found a way to access vim from more. Then, I was able to get a shell.
Some fun for fans of https://www.OverTheWire.org ;-)
Ready for #39c3 - this is what 5.ooo OverTheWire stickers look like
