had a stint as a programmer for a dark hat org back in the day and hacked my way around rdesktop to make it async. When i say hack I literally hacked down the entire codebase until there was not much left except the login flow which consisted of.. a LOT of functions that needed to be made async. I did not have the slightest idea what I was looking at, looked like arcane magic to me but I eventually managed to make rdesktop into what was probably the fastest RDP bruteforcer there was thanks to boost.asio and chopping it up months on end. I remember the bruteforcer that was circling the forums made a thread for each client, ate up a lot of ram and CPU and it crashed a lot too. Mine wasn't even keeping the machine at 20% CPU, couple gigs of RAM but was topping the bandwidth of the server.

I'm not proud of creating a malevolent tool but am proud of the technical achievement of it considering I just finished high school.
