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!”

For this one I used a website called FotoForensics to search for Hidden Pixels:


Unfortunately I did not get to complete many challenges here because I was spending most of my time on the NCL Fall 2020 Individual Game. But the few that I completed did teach me some new skills. I was mostly proud of getting that SQL one!

Happy Hacking! ❤
