Rooted, got the user.txt following root. This is probably the most ctf like box I have ever done. Can someone let me know what tool I was meant to use on the user file to reveal its contents?
Also hint for root, contrary to a lot of people here I wasn’t abled to just execute a binary and have instant root (could be people not resetting on free server). I was able to execute commands as root by modifying the right file. Easiest way to find is to think how you would locate all files that have different/abnormal permissions. Hope that’s not too spoilery!
