Just wanted to mention that all the things you are looking for are already in any download of Kali Linux. If you wanted to keep things simple that OS is specifically designed to be used for things like this. Probably would have more then you need to get going. Doing things like “find / -name wordlists” “find / -name webshells” will show you where these things are placed on the system. Also just using the Application menu in the upper left hand corner will show you a lot of tools organized by topic that you can jump in a learn about. Might be worth a look. Also to see practical examples of these tools just check out any of the @ippsec videos in the Video Tutorials section here in the forums. https://forum.hackthebox.eu/categories/video-tutorials
