This week, Dick O’Brien is joined by Symantec threat researcher Gillian Cleary, who discusses her recent research into the 100 most popular mobile apps, and how much information they are really gathering about their users. We also discuss an attack dubbed USBHarpoon that turns USB charging cables malicious, and we look at a court case in the U.S. where the government is reportedly attempting to compel Facebook to break the encryption on its Messenger service.
