People love to share information about themselves in person and online. Sometimes they give out way too much information. Here is a scenario. You are on Facebook and see that Hot Rod Magazines Facebook page has a 1969 Ford Mustang, Camaro, or Chevelle picture. In the caption, it states: “They don’t make cars like they used to.” Like this page and comment your first car for a chance to win a free detail package. Everyone could use a free car detail right? You like & comment: Fire Engine Red 1968 Ford Mustang GT 500.
Now you move along to check your online bank accounts. You put in your user name and password. Now you have to answer your security question. “What was your first car?” 1968 Ford Mustang GT 500. Now you’re in.
When you put your first car into the comment section of the Facebook page, now 3.6 million people that also like that page now know one of your three security questions for your online bank account. You should be using multi-factor authentication anyway, but that is another security tip for another day.
Again, the car is just an example. Many different social media interaction posts are often security questions for valuable assets you have online: favorite sports team, first pet, first job.
Try to refrain from giving out personal information that can be used against you.
