Many people are focused on the permissions they give Facebook when they install Facebook Messenger and are concerned that they are giving Facebook excessive access to their devices. This isn’t necessarily the case and this growing panic may be more a function of how Android permissions have to be obtained than a real privacy threat which many have read into those permissions.
I found myself listening to a discussion on 94.7 this morning about Facebook Messenger. The breakfast team was talking about these permissions that have attracted so much attention as if installing Messenger instantly compromises users and leaves them exposed to all sorts of privacy invasions when microphones and cameras turn on at someone else’s behest.
The panic level rose a few more notches when the breakfast team received a call from an anonymous listener who told the team that part of his work involves remotely accessing people’s devices (presumably part of lawful investigations) and exploiting these sorts of permissions. It wouldn’t be unreasonable to draw the conclusion that giving Facebook these permissions to access your phone’s microphone, camera and other features somehow makes all of those features available to anyone wishing to exploit that level of access and spy on you.
Fortunately it isn’t as simple as that. Leaving aside the risk that Facebook, itself, grants access to your devices to 3rd parties without your knowledge or that its apps have vulnerabilities which are not patched and are exploited by unscrupulous 3rd parties, Facebook isn’t the threat. I spoke to Liron Segev, an IT Consultant and one of the first people I think about when I need some help with the technical aspects of IT security. He explained that the threats to consumers come from various sources and that poor security awareness on consumers’ part is a contributing factor.
To begin with, it is possible for a 3rd party developer to introduce apps to app stores that appear to have a particular functionality but, below the surface, these apps will scan installed apps on your device, attempt to impersonate or even supplant those apps and exploit the access permissions you gave to the legitimate app. These trojan apps would then take advantage of the sorts of permissions you grant Facebook Messenger to access your device microphone, camera and other features. Avoiding this risk largely comes down to only installing apps you trust and how well the app marketplace is regulated and protected from this sort of malware. More and more security experts recommend installing anti-virus software on your mobile devices to help protect you from these sorts of attacks.
A hidden threat few people outside the security industry are aware of comes from the mobile networks we use every day. Mobile networks have the technical ability to gather data from our devices and even remotely install applications without us being aware of this in order to use that data and access to our devices’ features for a variety of reasons ranging from network performance management to remote surveillance and law enforcement. On the one hand, there are good reasons for networks and governments to have the capability to monitor criminal threats (for example, the somewhat misunderstood capability Google has to monitor Gmail for child porn using an existing database of problematic images). We live in a world where the bad people use advanced encryption and digital tools to plan and conceal their activities. On the other hand, there is also scope for governments and companies to use these capabilities to spy on citizens, infringe their rights and exploit their personal information for profit. As I mentioned in my htxt.africa article “Much ado about Facebook Messenger privacy settings, but is it nothing?” –
Whether you use Messenger should be informed by the extent to which you trust Facebook, not by the very explicit and informative permissions Facebook seeks from you in order to use Messenger. If anything, Facebook is just proving that it has come to a long overdue realisation that there is no benefit in deceiving users.
It is possible that Facebook may turn on your phone’s camera and microphone while you are getting dressed in the morning but highly unlikely. What is more likely is that Facebook requires those permissions to enable Messenger to do what you want and expect it to do. That said, you can’t be complacent and install every app on your device that seems amusing. Take the time to satisfy yourself that the app is from a credible source and look into anti-malware software for your devices. As for mobile networks and governments, there is little you can do except reconsider your device choices if you are concerned about this. Segev pointed out that Blackberry devices are still secure options and Blackberry 10.x is a flexible option even if it isn’t popular media’s darling.
