OverTheWire is great practice! Bandit starts off easy, but they go up in difficulty quickly. I'm looking to create some similar lessons + challenges geared toward appsec for developers - there's a sample lab available at https://labs.hunter2.com/demo https://labs.hunter2.com/demo and I'd welcome any feedback on the approach. (The demo is more a Codecademy-like lesson, but I plan to add some CTF-style challenges as well.)
