[Dicaprio]

An individual sued my father.
I have that individuals:
-IP address, could be IPHONE or LAPTOP
-Personal email address
-Full name of individual
-Physical Address
I would like to find a way to hack onto there laptop or iphone and download all pictures to use blackmail them.
MY question to yall is what type of, specific, attacks can I run? I have Kali Linux which I am familiar with basic WIFI attacks but I think what I am trying to accomplish may be above my league. Any suggestions that would point me into the right direction would help! Please reference any Linux applications which would help for these attacks.
