Apple touts how easy it is to make Siri carry out simple, helpful commands, but security experts have been saying for years that the digital assistant makes it too easy for anyone to skim your personal information from your iPhone and access apps and services. Unless you make Siri inaccessible from the lockscreen, anyone who has hold of your device for as little as 30 seconds can make Siri post to your Facebook account, display all of your contact information and edit your upcoming appointments.
