I felt like going back and writing up this warmup challenge from BCTF since I enjoyed it so much. I have just recently finished studying RSA at university so it was still fresh in my mind when starting this challenge.
CTFing at Easter time was super challenging. Endless family commitments, using my iPhone to browse challenges while at the dinner table and thinking through how to attack them when I can finally get to a PC. Fortunately NDH seemed to go for long enough for me to at least try a few of the challenges, which I did!
Didn’t have time to do UIUCTF this year since it ran concurrently with NDH but I did this challenge to help a team member out who was doing it and it only took 15 minutes. It was a fun challenge called hype, worth 100 points.
