TamilCTF: Ransomware

Fun CTF for TamilSec Con 2021 which wasn’t taking itself too seriously. This was the group’s first year and it was clear they had a lot of fun trying to come up with creative new challenges.

DownunderCTF has become a big event in the yearly CTF calendar. Nice job all involved! It’s also one of the only CTFs that is run in a cloud region geographically near me. Loved the super fast ping times to all the infrastructure. What a luxury!

COMPFEST13: Snab
