I attended a cyber security session put on by one of the big insurers and someone there demonstrated how easy it was to obtain details for people who have a social media presence, in particular Facebook and Instagram but not exclusively. One of the easiest ways to obtain info is by looking at their profiles. This is because people give their birthdate or post birthday photos, give children and grandchildren's names etc, which are often used as passwords, post when on holiday (thus alerting they are away from home) etc. With surprising ease he was able to access the email of a CEO, know where they lived, how many children and names of children etc, all done within minutes. It is always best to keep info to a minimum.
