Here is another CTF problem from last years Army Cyber Stakes Challenge. You are provided a solid line of characters (see below) and have to turn it into the flag. The trick is that because there aren’t any line breaks, you have to figure it out.
_ _ __ _ ____ _______ _____ _ _ | |__ ___ _ __ ___ (_)___ _ _ ___ _ _ _ __ / _| | __ _ __ _ _ | __ )_ _\ \/ / _ \| \ | || '_ \ / _ \ '__/ _ \ | / __| | | | |/ _ \| | | | '__| | |_| |/ _` |/ _` (_) | _ \ | | \ / | | | \| || | | | __/ | | __/ | \__ \ | |_| | (_) | |_| | | | _| | (_| | (_| |_ | |_) || | / \ |_| | |\ ||_| |_|\___|_| \___| |_|___/ \__, |\___/ \__,_|_| |_| |_|\__,_|\__, (_) |____/ |_| /_/\_\___/|_| \_| |___/ |___/
There isn’t a ton of skill required for this one. When I paste the entire thing into Notepad ++ (turn off the line wrap), I see a bunch of underscore characters to start with that I take to be the flat tops of other letters. So I went ahead and put a return where I saw the first non-flat character (position 106). When I do that, it drops the rest down, and it looks close, but not totally right so I took it back one space to 105. From there, just keep dropping the line down at each the same spot until you get….
