In my quest for computing knowledge I stumbled across a recommendation, probably on /r/howtohack, to check out Over the Wire’s Wargames. Wargames being a set of challenges that require you to complete various computing and security tasks to then progress to the next level.
The particular one I started with is Bandit and is completed entirely in the Unix command line using commands that you are provided with and some that you aren’t. The site provides some resources for reading about the different commands but it also suggests using Google to its full potential and I have to echo (haha) that suggestion.
I’ll be making a series of posts about either a group of levels, if they are easy enough to explain a few at a time, or a single level, if it takes a bit more effort.
