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.

In November 2016 I wrote a post about the iOS WebView Auto Dialer bug specifically in the iOS Twitter and the iOS LinkedIn apps. Last weekend I finally had the time to retest those apps to see if the bug was fixed. Retests in December and January showed the bug was still present (as far as I remember). Both apps are fixed now!
Playing around with this a bit more I discovered a new security warning on iOS. There now seems to be a detection for the case where a website automatically tries to open a TEL URL. The dialog doesn't always appear but when it does you first have to click allow before being presented with the actual Call/Cancel dialog. Neat!
The conclusion seems to be that the bug was fixed and that they added a new detection and warning dialog. Good!

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!

The European Union Agency for Network and Information Security (ENISA) asked Ioannis Stais, Vincenzo Iozzo, and myself to update their guidelines for secure smartphone app development. The result is not much of an update but an entire rewrite of the guidelines. It was a fun project to do and I think all parties involved in the project are proud of the final result.
The Smartphone Development Guidelines website provides a brief overview of the effort. The actual document can be downloaded here Smartphone_development_Guidelines.pdf
I would like to thank everybody again who helped on the project the project coordinators at ENISA and everybody who reviewed the document and provided feedback!

CFPs backdoor story is just bad and will drive users away from a secure messaging app (maybe even the biggest install based of all of them). Zeynep Tufekci wrote an open letter to the Guardian to have them update the story. Moxie also wrote a blog post about these claims. The Guardian should have asked people with the technical expertise for advice before publishing the story.
