Hi! My name is Valter (a.k.a Blupper) and I’m a student and CTF player from Sweden. You might see me playing with the Swedish National Hacking Team, RoyalRoppers, KebabEngineers, or just solo.
My (semi) recent obsession is with cryptography, but I also do reverse engineering, pwn and web when in increasing order of desperation.
I put my projects on GitHub and some blog posts/writeups here. Contacting me is easiest via @blupper on Discord.
