If you have a SmartPhone and it’s not an iPhone, not a Windows Phone and not a Blackberry then you probably do, and this puts you at serious risk.

Simply put, using a flaw that’s been called “StageFright” hackers could easily steal contact information, personal details, track your location and install malicious apps without your knowledge.

All they have to do is send you an infected MMS, effectively a text message with a picture, and just receiving the message is enough to infect your phone.

Security provider, Lookout, has developed a free test that will check whether your phone is at risk, there are probably other tests but I use, and trust, Lookout which is why I’ve made this recommendation.

If you are vulnerable, Lookout will advise you as to how you can minimise the risk, but you can do this without running the test, if you wish.

Open your Text Message App, go to “Settings” and disable “Auto Retrieve”. You might have to do the same for Google Hangouts and Facebook Messenger too, if you use them.

Now, Google is working hard on a fix but it’s not going to be rolled out for a little while due to a whole range of complexities”
