Cyber attack against PlayStation and Xbox

Jonathan Beales, a computer games expert currently making a documentary about the Playstation told Today's Mishal Husain that it's been a "real contrast of fortunes" for Sony who just celebrated 20 years of PlayStation at the beginning of the month.

Mr Beales said that he was surprised that PlayStation didn't appear to have "allocated resources and time to make the security more robust", after being hacked last year. He said that, while the networks "couldn't admit the hack", there needed to be a call for increased security.
