iPhone lock screen hack means your pictures and contacts may be accessed without a passcode

Hackers can bypass iPhone security and access photographs, contacts and address books on devices with no need for a password, according to a report.

Hot For Security’s Graham Cluley revealed that Siri – iPhone’s voice-activated software – can help hackers bypass an iPhone’s passcode.

The hacker needs access to an iPhone, but no knowledge of the phone number.

If Siri is enabled on the device’s lock screen, a simple question – “who am I?” – will prompt the phone to reply with the owner’s name and number.
