Syskron Security CTF (21–26 Oct, 2020)
“The 2020 Syskron Security CTF event is a free online cyber security competition for everyone. This year’s CTF event features an original background story! You act as a cyber security professional, working for a Czech manufacturing company.
We provide 20 challenges focused on industrial security (all levels of difficulty). Most challenges are derived from real-world security problems, so you have fun and learn about actual cyber security!”

Happy Hacking! ❤
