Smartphone Security Alert

This message applies to ALL smartphones running Android. That means if you have a Samsung, HTC, LG, Motorola, Sony, ANY smartphone running Android you need to take action as detailed in this blog post.

Some of you may be aware of a security alert called Stagefright. It is a problem for Android smartphones that is serious enough for you to take action, NOW. While it only affects MMS messages, everyone still needs to take action and turnoff the auto-retrieval of MMS messages.

If you currently use MMS messages regularly (whether work or personal) we strongly recommend that you move to using an application like Google Hangouts. There are other possiblities, however using  Google Hangouts and your salvationarmy.org.nz account will tie everything together (e.g. Google Drive and Apps data) and enable you to see the complete Territorial directory.

Even if you don't think you receive MMS messages you need to make the following changes to any/all of the applications listed below that you have on your phone. Also if you're using a different app for SMS messages then check the configuration of that and ensure it is set to NOT AUTOMATICALLY DOWNLOAD MMS messages.

The rest of this blog post shows the different apps you MAY be using for SMS messages and how to change the settings to protect yourself.

Messaging, Messenger, Samsung Messages, Hangouts, whatever messaging app you use, they will ALL need to be updated IF they're on your phone. It only takes 30 seconds and will protect you.

In each case you need to follow these steps:

  1. Launch the app (e.g. Messenger)
  2. Click on the menu / hamburger button
  3. Select settings
  4. Go to advanced settings
  5. Ensure auto-retrieve of MMS (multimedia) messages is switched OFF

Beneath here are screenshots for Messaging, Messenger, Samsung Messages, and Hangouts. Each screenshot has a number that corresponds to the above list of steps you must take. Thanks for taking the necessary steps to protect you and your device.

Thanks Mark,

Took me awhile to find Settings in my SMS Messaging (I don't use MMS) but eventually found it and unticked box. Also alerted rest of staff in my office to this to do the same. Having turned it off, how will messages now come into my inbox?

Great job. MMS messages will still be received, just not automatically. This gives you the opportunity to consider who the message is from and whether or not it is a genuine message (similar to email attachments).

Is the Viber phone app vulnerable to this attack?

According to a quick Google search MAYBE. What matters is that your DEFAULT messaging app DOESN'T automatically retrieve MMS messages.
