Apple iPhone lockscreen bypassed, with a little help from Siri

Siri is amazing. Apple’s voice assistant makes a lot of smartphone actions easier, and is funny to boot, chiming in with the occasional joke, when asked the right question. But we are sure Apple didn’t design Siri to be so polite and helpful that ‘she’ would let just about anyone in to the phone.


But it looks like the iOS 7.1.1 update does just that. Earlier we had seen the iPhone’s lockscreen being bypassed using the emergency call button and a combination of other presses. Now the new trick allows anyone to browse all contacts stored on the phone and make a call to any one of them.


What makes the iPhone vulnerable is Siri on the lockscreen. Even when the phone is locked, Siri can help you out with a few tasks including showing your contacts and sending messages. However, if you ask Siri to show you the contacts, you would need to unlock the phone first. That’s not necessary if you ask Siri to make a call.

Sherif Hashim who discovered the flaw, says the only way to keep this vulnerability at bay is to stop the use of Siri on the lockscreen, till Apple delivers a fix. Apple is yet to respond to the latest flaw, though in the past, the company has rolled out fixes for each of the lockscreen bypass tricks.
