I've been looking into hacking and starting off pretty well. I have already learned how to scan networks and find devices connected as well as read open/closed port information. I can code basic python and possibly learn other languages. If I wanted to hack into a laptop, my personal test laptop, and take advantage of some vulnerability how would I do so? without accessing the computer at all other than through another computer. My goal is to know how to get into another computer and insert a file or program and create a backdoor to get in later. But, as I've been searching for some guides, nothing has been helpful. This is important for my experimentation.
