The road to #ECSC2025 has officially kicked off! We just wrapped up our first qualifier event to select the 10 members of Team Austria who will compete in the European Cyber Security Challenge #ECSC in Warsaw later this year.

Over the weekend, 30 participants focused on attack/defense training with #ENOWARS CTF and tackled some great challenges from #DownUnderCTF. Nice to see so many young and motivated hackers in action.

Huge thanks to IKARUS Security Software for hosting us, to my co-coach Manuel Reinsperger, and to everyone who spent the weekend hacking, learning, and having fun together. Looking forward to the next round.

I had deleted it from pin toots, really good website for CTF noobs like I. Good luck !

Yesterday I participated in the #CTF session hosted by @lisihocke at #socrates2025. Today two persons asked me if I do penetration testing for work. While I do not do that (and also am note sure if I want to do solely that) and also do not feel like a person being able to do this, it was a very rewarding situation. The work I put into learning about this topic seems not be lost.

DEF CON 32 was my very first hacker summer camp, and I absolutely loved the experience! However, I was disappointed to discover that Hack-A-Sat had been discontinued, and there were no space-themed CTFs that year. We decided we couldn’t let @defcon 33 go by without bringing the excitement of space hacking back—and now, we’re making it happen!

https://andy.codes/blog/personal/2025-07-18-starpwn-2025-ctf.html

Get ready for a stellar lineup of challenges at STARPWN CTF! Whether you’re joining us online or onsite, we can’t wait to see the best hackers push the boundaries again. Suit up and join the mission—I hope to meet you there!

In a rare act of preparedness, we actually updated ostrichlab.io before DEFCON. We dumped a bunch of backlogged CTF writeups, added some fresh info, and probably broke a few links in the process. If you're into cyber mayhem, bad ideas, and technical documentation with commitment issues, it's all waiting for you.
