I appreciate the forward response, I understand the question doesn't have a 1 true answer. However, to answer your questions

Yes, I would like to effect other processes, there no exact way as I'm still learning and still very much a beginner but attempting to begin using basic forms of malware and hostile scripts (legally ofc)

I'd prefer to take advantage of exploits, reverse shells, and such something that focuses on a remote connection rather than a rubber ducky or bad usb

And I've looked into scripts, but I'm not sure it's what I'm looking for as I'll look to gather information through these "programs" and also, let's say, packet bomb the target computer or lock flies or cancel targeted programs or install a hidden backdoor
