Facebook says glitch exposed 6 million users

Facebook has inadvertently exposed 6 million users’ phone numbers and email addresses to unauthorised viewers over the past year,the world’s largest social networking firm disclosed late Friday.

Facebook blamed the data leaks,which began in 2012,on a technical glitch in its archive of contact information collected from its 1.1 billion users worldwide. As a result users who downloaded contact data for their list of friends got details that should not have been leaked.
