There are three major credit reporting companies in the U.S. The three companies possess an enormous amount of personal information about you. Make a major purchase, like a house, and your credit report will be consulted.

So when the data of one of those three -- Equifax -- was breached earlier this month, it had potential to be disastrous for millions of people. In fact, personal information such as social security numbers and birthdates of up to 143 million people was exposed.

The attackers could use that information in many ways that could ruin your credit and finances for years to come.

So how does one protect themselves from hackers?

On Wednesday's Smart Talk, we joined by Andrew Hacker (yes, that's his name) who is the Cyber Security Expert in Residence at Harrisburg University of Science and Technology to answer that question.

Also, in 1927, the Germans set to sea the Cap Arcona, a luxury liner to rival the Titanic. Once Hitler came to power, the ship was actually used as a stand-in for the Titanic in a feature film full of Nazi propaganda.

During World War II, the Cap Arcona served as a transport, a troop barracks and a floating concentration camp for Jews imprisoned by the Nazis. The demise of the ship is even more tragic and little known.

Author and historian Robert P. Watson tells the tale of the doomed Cap Arcona in his new book, The Nazi Titanic. Watson joins us on Smart Talk to tell the story of the doomed cruise ship.

Robert P. Watson is the featured speaker at Chizuk Emuna Congregation in Harrisburg October 8th at 4 p.m
