It's all fun and games ... Social Media
Have you ever seen the lists that people post on ... "Get to know each other better." It's all fun finding out if you're friend has ever sat in the back of a Police car, but please be aware of some of the posts you comment on. The posts or lists that ask:
what was your favorite teacher's name
who was your first grade teacher
who was your childhood best friend
your first car
the place you born
your first pet
etc.
Those are the same questions asked when setting up accounts as security questions. You are giving out the answers to your security questions without realizing it. Hackers are setting these up as a get to know each other better game. They then build a profile of you from several different data sources. They use this data to hack your accounts or open lines of credit in your name.
