Having a week off from work, I figured "Why the heck not? Let's try a CTF". Working in Cyber Security, I have had multiple hours at TryHackMe, working on gaining experiences and building up knowledge that further can help me in my daily blue teaming work, as well provide a few hours of fun at home. But I had still to participate in my first real CTF challenge.
GuidePoint launched a CTF challenge on tuesday august the 10th, and I started right off by registering for the event and setting up my MalwareLAB to connect using the provided VPN.
On the Challenges-page we see a list of all the categories and the individual challenges as pictured below (picture taken after I finished the CTF).
In the next few posts, I will go through my thought-process and write up how I solved the different challenges. Though not including the "Sanity Check" challenge, as this mostly was a challenge to verify that the systems worked and I could reach them (the flag was given right at the challenge).
After a few interesting days of on-and-off hacking, decoding, Python-scripting, information seeking and challenge-solving; I finished the CTF in a time placing me at 7th place (out of around 280 participants) - like WOW, who would have throught that? Maybe it wasn't the most challenging CTF, I don't know. But for me, that was fun!
