I’m Tareq from Knight Squad.
Recently we played RCTS CERT CTF 2021. Here I’m going to give you a quick writeup for the challenge named “Hextraordinary Security“. let’s dig into it.
The challenge prompt was “We just found this garbage file. Can you decode it and retrieve any useful information from it?”
We were also provided with a downloadable file. The file contained hexadecimal data.. I browsed to cyberchef & paste the data. After that I just did hexdump & got the flag.
That’s it. Hope you guys enjoyed. Don’t forget to share your feedbacks in the comment section below and stay tuned with us for more interesting challenge walkthroughs.
