They played, they captured the flag, they had fun, they learned! And here is what they
had to say after their Hack The Box CTF experience.
The HTB UNI Qualifiers CTF 2020 was really great. The challenges were very well-engineered and there was a great variety in the type of content distributed across multiple categories in the CTF. The CTF was overall very structured and precisely planned, and I really enjoyed the event in its entirety.

Playing CTF on Hack The Box is a great experience, the challenges are of high quality as you know them from the platform and they range from beginner to pretty insane. I found the support to be quite fast and timely and we were always in the loop about what was going to happen. The platform worked well, submitting the flags felt satisfactory and challenges started on demand fast and smoothly. Overall 5/5, would (and will) play again.

We did it again! Thanks to the support of HTB and its fantastic team, we were able to run the RomHack CTF 2020 edition. We received exciting comments by the players on the organization of the CTF, the challenges, and the CTF format with a 10 mixed difficulty challenges (on many topics from crypto to hardware hacking). We want to sincerely thank Hack The Box for being so friendly, professional, and open to collaboration.
