Google Probing Role by Employees in Cyber-Attack

Google is investigating whether one or more employees may have helped facilitate a cyber-attack that the U.S. search giant said it was a victim of in mid-December, two sources told Reuters. Google, the world's most popular search engine, said last week it may pull out of the world's biggest Internet market by users after reporting it had been hit by a "sophisticated" cyber-attack on its network that resulted in theft of its intellectual property.
