since I always rant about how I don't like biometrics in smartphones some people have asked me to formulate what I actually would like to see to happen in this area.
My dislike for biometrics is that you cannot change your password anymore because your password is your finger, eye (iris), or face. That means you basically show you password to everybody. A good example of this is here: Politician's fingerprint 'cloned from photos' by hacker.
The second part of the problem is that many biometric systems can be easily bypassed, some face recognition systems even with a picture shown on a smartphone screen.
My main issue is that biometric systems can be bypassed by forcing the owner of the device to unlock it. This can be done without leaving evidence, a funny example of this issue: 7-Year-Old Boy Uses Sleeping Dad's Finger To Unlock iPhone. Also see this interesting case: Court rules against man who was forced to fingerprint-unlock his phone.
The main argument I always hear is that people who wouldn't set a password (or use just a simple PIN) are using biometrics and therefore are more secure now with the help of biometrics. The kid from the previous story wasn't stopped by biometrics it was just as good as not having a password.
What would have stopped the kid from unlocking his dad's phone? A simple timeout! Basically what I want to see is a timeout for your biometrics. Once you entered your password you can unlock your phone using biometrics, after a specific amount of time you have to re-enter your password and cannot unlock the device using biometrics. With a timeout of say 30 minutes to one hour you can prevent simple attacks while still being able to use the convenience of biometrics. Apple recently introduced the SOS mode that will also disable biometric authentication until you enter your password. I wish this was taken one step further and let you set a timeout.
I personally see biometrics on a smartphone as a pure convenience feature and treat it as a weak security feature. I only use it for ApplePay.
I think it is pretty bad to get people used to biometric authentication, Apple may get it right but other companies wont. Normal users can't determine this easily. Also how much did the additional hardware components cost to implement fingerprint authentication or face recognition. FaceID doesn't use a normal camera so there are definitely additional costs that you as the user have to pay for this convenience feature.
Face recognition in consumer products also gets people to accept this as an normal everyday thing and thus helps the argument for face recognition being used in surveillance.

The Qualcomm Mobile Security summit was excellent again! Fantastic talks and again I met a bunch of people I mostly knew from email and/or twitter or haven't seen in quite some time. This conference still is unparalleled!
I had a minute to play with the BlackBerry KeyOne and it feels like a super solid device. The screen is bigger then I thought it would be and this makes the device almost too big for my taste - but this is hard to say from playing with it for just a minute.
So iOS will finally support NDEF tags.
This talk is really interesting for anybody interested in mobile application security. This is not about mobile app reverse engineering but about app, backend, phone infrastructure interaction.

Google published a blog post and a detailed report on Android Security in 2016. The report covers everything from patching and update stats to high impact vulnerabilities. People posted a lot of summaries but you should really read it yourself if you work with Android.
Google pulls March security update for Nexus 6, after it breaks SafetyNet and Android Pay. This was pretty interesting, not the fact that they broke SafetyNet but that they broke it for their own devices (Nexus). This happened to some really small manufacturer before and if you have an idea of how SN works on the backend - it is clear what happened.

I took a way too long break again. So many things happen in the world of mobile security every week. I really wish I had more time for this. I also have a bunch of small things I need to put on this blog but I think they are too specific for the news and will likely get their own posts.
Some news from MWC (I didn't attend):
First the BlackBerry KEYone a new Android-based phone with a physical keyboard. Other then the BB Priv the KEYone's keyboard is fix and doesn't slide. Movable parts are really not a good idea, they break way too fast. In my opinion this device looks super solid and likely will be supported longer than the average flagship phone from other manufacturers (data on this would be awesome).
Nokia released 3 new Android phones the 3 (MTK), 5 (QCOM) and 6 (QCOM). The phones seem to run Android N without any modifications or vendor crap. Very low price (230Euro for the 6). The bottom of their website specifically says: You get an experience that's focused and clutter-free, and we'll make sure you keep getting regular updates, so you'll always stay on top of features and security. that is what you should expect in 2017.
The Android Devices Security Patch Status page is an awesome resource to determine if a specific device from a specific vendor has been patched and when the patch was released. From the page: This list is Prepared to Serve as a Quick reference to identify which Device is being actively maintained by the Vendor.. This is super useful, thanks!

Recently the topic of SMS 2FA came up again. While I agree that SMS is not the most secure version of 2FA it is far far better then not providing any 2FA mechanism for your service.
