It’s almost 6 months since the last post, so to keep some good yearly average it’s finally time to write something here. For the last couple of months, most of my spare time went into various CTF challenges. Since I’m very new to CTFs, usually I’m not able to solve top scoring tasks and people familiar with CTFs probably know that challenges with lower score are not really interesting enough to write anything more than a few lines writeup (and there is usually dozens of writeups already published, before I even think about writing something). So this time it might be a bit different since the IceCTF was 2 weeks long, and I could prepare some good writeup before competition ends. I did two pwn tasks, which are actually very similar to each other.
