Rather than programing challenges with Advent of Code, I thought I'd list a few different (FREE) hacking events. Challenges range from very easy to (very?) hard. Some of the stories and can be cringeworthy, but the challenges are good. Have fun if you decide to try any or all of these events! ![Cool :cool: :cool:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
