Siri on lock screen shows contacts

When you tell Siri to call or text someone you can without a Passcode. A list of all of your contacts are also accessible through Siri while your phone is locked.
 
That's why they give you an option to turn Siri off from the lock screen.

Convenience vs security. Choose one.

Isn't this a bug in the software?

Well not really. It's common sense. If you want to be able to use Siri from the lock screen, certain things are going to be made available (internet, calendar, contacts, messages, etc).

The option is there to turn it off.
 
Wasn't it petty much always like this since the day Apple introduced Siri (and not just something in iOS 7.1.1 or even iOS 7).

Yes it's a bug IMO since Siri ask for a passcode to access contact list but it can be defeated.

Yes, Contacts are blocked if you ask for them directly, but you can get around it with this exploit.

Are we sure this isn't how Siri always worked?

That aside, given that an iPhone 5S seems to be used in the video, and between asking Siri about "contacts" and then saying "call" it looks like the person holds one of the fingers on the home button for a bit--perhaps that unlocks the phone via Touch ID and that's why the subsequent actions allow for Contacts to be accessible?

I just did this on a 4S, it isn't because of Touch ID.

So then basically what Siri has always allowed to do. Doesn't seem like anything new or surprising really.

Why when you tell Siri "Show contacts" does Siri say "You need to unlock your iPhone first." But if you do it this way it lets you view all contacts freely, it seems like a programming mistake.

Different use case in a sense. But still certainly something that's been around before iOS 7.1.1, and perhaps even as far as the introduction of Siri.

Another video of this kind of thing from a few months ago: http://www.youtube.com/watch?v=xYuO9k0_WBA

There are probably videos and mentions of this from even before, so not sure why it's making news now really, unless somehow this particular behavior is something truly new in iOS 7.1 or 7.0 somehow.

This is new in 7.1.
 
I've searched and all results are from March 2014 forward, I've also heard that it does not work on iOS 7.0.
 
What exactly needs to be said to an iOS device for this? I'm wanting to test it on an iOS 5 device. So far, it works the same as it does on iOS 7 and 7.1.

Tell Siri to text or call, when she asks who to send it too, say a name that isn't in your contacts and press Other.
 
Happens on iOS 5 as well. Not a bug, more like a feature as it can be disabled via Settings.
 
I guess it was designed this way then. You can do more on the lock screen than it appears.
 
It can't show you a list of contacts.

You can however ask Siri to give you someone's specific contact information, which is definitely something Apple should fix.
