I participated in this year's CSAW qualifying CTF. I didn't do much, but I succeeded at some binary exploitation, reversing some python, utilizing hashcat to crack some hashes and doing an easy web challenge. I also managed one of the harder web challenges - albeit after the competition ended. 
I greatly enjoy the CTF format that to me is like a bunch of bite-sized puzzles, forcing me to think about things I rarely get to think about 🤯

I wrote a program that plays Minesweeper. Initially I tried screenshotting the game and to image recognizion, but ended up using the Win32 API to open the game process and read the memory containing the board layout.

I made a website, hurtig.ninja, a filesharing site that's simple and anonymous to use. I often wanted to share files (and still do) and needed a better solution than any existing one.

It's made with Typescript, .Net Core, running on an Ubuntu server with MongoDB to store references to files.
