Barb Darrow, writing for Fortune: Corporate IT pros face the unenviable task of trying to protect valuable data from threats that change all the time. One vector of attack is clearly smartphones and tablets that employees use both for work and pleasure. To that end, mobile device management firm MobileIron just came out with its latest tally of the ten most blacklisted apps, based on a survey of 7,800 companies worldwide. Angry Birds tops the list of most-banned apps at companies worldwide, as well as in Australia, the U.S., and government sectors tracked by MobileIron in its twice-yearly Mobile Security and Risk Review. The survey covers the use of Android, iOS, and Windows devices from Oct. 1, 2016 and Dec. 31, 2016.
