The first part of any type of hacking no matter what it is. Is gather information.
You need to know about the machine or person you are hacking. There is a lot of tools out there that will help. Even just a simple google search will reveal a lot about your target. For example, I am wanting to hack this person named Bob, well I would first like to understand him a little better and maybe what devices he uses. So I can look at his twitter page where he might talk about what phone is using. The more you know the better it is.
