News that technological monitoring of mobile electronic devices could have a role to play
in beating Covid-19 will raise a predictable outcry from the freedom
warriors. How dare the authorities use our data to determine who is infected, where we travel, and whom we may have
met? Never mind drones monitoring your
walk in the Dales, your phone may soon start to bleep to warn you that you are
too close to some oncoming ramblers. It
all sounds very big brother but, in the context of other extraordinary
measures, it seems a very small privacy price to pay if we are to get back to
work as soon as possible.
Although there could be some regulatory oversight over how
your phone data was processed and used, it could be useful to remind ourselves
that criminals in cyberspace are under no such inhibitions. Indeed, as our use of the internet explodes
because of the recent physical confinement, there will be rich pickings for
people with bad intentions. Now I stress
that I am not a cyber expert - everything that follows is my opinion.
One of the easiest ways to hack your mobile phone is to set
a trap on a public Wi-Fi network. A
resourceful rogue could set up a “free” Wi-Fi hotspot that appears just like
something that might be offered by a hotel or supermarket. Except it is not what it appears and clicking
on the link to sign in could open your phone to all sorts of trouble. Of course the password you used to log on was
unique wasn’t it so there is no possibility of a thief using the same password
to open another of your sites? And its
no good saying that I never do anything of security significance, like banking,
on an open Wi-Fi network because once they are in your phone they can find
pretty much everything. Even if the hotspot
itself is not fake, there is no guarantee that bad people could intercept your
activity. I am very grateful for the timely
reminder from Jennifer Arcuri, writing in Standpoint, who says, “with free Wi-Fi
we have no idea who else is on that network or what they are doing with the
information we exchange over it. We do
not even know if the owner of the free Wi-Fi is really who we think it is.”
It is very tempting, if your phone contract places a limit on
the ration of mobile data each month, to use so called free Wi-Fi networks but
we should be very careful. I looked at
my phone this morning and found that, historically, it had remembered 149 wi fi sites that I
had previously used (phones have long memories). Most of these were
legitimate like LNER or Cross Country but dozens could have been anything. So and so’s cafĂ© free Wi-Fi, in retrospect,
looks potentially suspicious. So, I told
my phone to “forget” most of the site apart from my home wif and a couple about
which I could be certain. I ticked the
box which prevents my phone from logging in automatically to any Wi-Fi it might
encounter in future.
So after half an hours housekeeping this morning I have
formed a new security resolution and to be very careful where I log in in
future and make life as hard as possible for cyber criminals. Meantime, big brother is welcome to my movement data
if it helps the current fight.
