You may remember that earlier this year we were all talking about the
standoff between the FBI
San Bernadino attack. This specific problem was "
solved" when the FBI said they were able to decrypt the phone and no longer needed Apple's help. The assumption by many is that the FBI purchased an exploit used to break into the phone.
and Apple about the decryption of an iPhone used by one of the shooters in the
This leads us to an important consideration and question... can any phone be hacked? Is any information on your smartphone really private?
We have become completely dependent upon our phones. According to a 2015
Pew Research Center
study, in the US over two-thirds of the population uses a smartphone. We keep all of our personal information on there: passwords and accounts, photos and videos, credit card data, tax data; we shop and set many preferences (travel, food, dating, real estate); we track our workouts, our weight our food and all our movements. Today's smartphone is the key to far more information about you than you can imagine!
We can, of course, watch TV on our phone. And on 4/17/2016, 60 Minutes aired a show about smartphone security and privacy. You can view it
here.
In the episode, they talked about the SS7 (
Signaling System 7) protocol and how it works.
SS7 was designed in 1975 and it is the protocol that allows phone systems to pass calls between them. For mobile, it handles maintaining connections as you move between cell towers, for example as you are driving down the road (using hands-free calling of course! :-). This particular exploit is
not new at all. In fact, this has been a topic at the
Black Hat Briefings and other
security conferences for
years.
But all this aside, there is no need for exploits or vulnerabilities to track people or glean personal information through their phones. Disclosing this information is simply how phones and apps work! Let me explain...
