🚩nitrozeus's CTF Writeups

Write-ups from various CTFs that I've participated in with my friends.

What is CTF?: Capture the Flag (CTF) in computer security is an exercise in which "flags" are secretly hidden in purposefully-vulnerable programs or websites. Competitors steal flags either from other competitors (attack/defense-style CTFs) or from the organizers (jeopardy-style challenges).

root@nitrozeus:~# whoami

My online persona goes by the name nitroz3us. Currently, I'm a student at Singapore Management University (SMU). I served in the military for three years, between 2018 to 2021, and was posted to a Cyber unit (inaugural batch of CyberNSF). I'm a cybersecurity addict and contrary to popular belief, I love blue team over red team. I am fairly new to CTF so join me on my journey to many more CTFs to come!

I love the idea of finding ways and trying to be ahead of the hackers, the same way, they try to be ahead of us. My end goal is to work in a Digital Forensics/Incident Response (IR) team. Currently, I have three years of SOC experience.

I've worked in, both as a SOC Analyst;

• Cyber Security Agency of Singapore (CSA) under National Cyber Threat Monitoring Centre (NCTMC) division

• Ensign InfoSecurity

Good to know: You can participate in any CTFs either alone or as a team. It's way more fun to compete with a team in my opinion. Sharing ideas and knowledge helps with the learning curve.

As of now, I do not have a dedicated team, most of my CTF's participation are with a group of friends which often changes between each CTFs.
