How to hack into or gain access to iPhone or android device via PC over network?

So basically, I wanna know how I how I can screw around with peoples phones and make weird $#!^ happen from a PC.

I've got Wi-Fi on my bus and i've been able to gain admin rights to it. So i've got everyone's local ip (ipv4) and mac addresses.
How can I use these to my advantage?

So basically, you want to do illegal things to other peoples' equipment.

Unless you have their permission to "screw around" with their phones, what you are trying to do is a criminal act.

Fingers crossed they have a weak password.

You could potentially instigate your very own fapening.

Let me translate your question into blunt language:

You wish to break into other people's equipment and see what sort of spying and damage you can do. This is like breaking into someone's house, going through their belongings, taking what you want ad damaging the rest. Both activities are unethical, immoral, illegal, and irresponsible.

Also your question violates the terms of use of this forum.

Now grow up and behave.
