'Highly visible people' are the people easiest to identify in your business or school. You need to know who these people are, as they will be the ones hackers will most likely target.

Hackers are predictable. They always start by gathering as much information as possible about your organisation. This can be technical details but is increasingly focussed on the people who work for you.

Once hackers know who works for you, they use two main ways to break into your computers. Firstly, hackers search lists of stolen passwords they can use to get in through the digital front door. Or they use your team's personal information to carry out phishing attacks. Phishing attacks are designed to trick people into revealing even more sensitive information.
