Why are retailers becoming the primary victim for cyber-attacks?

Listen to this episode from The Pat Kenny Show on Spotify. Just weeks after UK retailer marks and spencer was hit by cyber-attack, luxury department store Harrods was another company who fell victim to an attack.  Harrods said they experienced attempts to gain unauthorized access to some of our systems.  So why are so many retailers becoming the target of cyber-crime?  To discuss further Pat was joined on the show by Dermot Williams, Managing Director of Threatscape, an Irish Cyber security Company.
