>> STOCKHOLM TERROR ATTACK: HOW IoT COULD HAVE PREVENTED IT
It is shocking to see such a cowardly act devastate lives - my condolences
for those affected.
On Friday; just before 15:00 local time - the unthinkable had happened in
the peaceful city of Stockholm, a place I called home (and still do) for
a good chunk of my life. A rejected asylum seeker, supportive of ISIS, who
went underground last year decided to highjack a beer truck and mow down
innocent civilians in the busy pedestrian only streets of Stockholm.
I was lucky enough to pass through the exact location just an hour earlier -
however, I was within five hundred meters of the tragedy when it happened.
It is sad to think however; that a simple IoT device could have prevented
this from happening in the first place - something that may need to be
considered as an industry standard to be retro-fitted for all vehicles that
can cause such damage.
I wrote a small sketch that would allow the remote disabling of a vehicle
As complicated as it may seem, it doesn't involve much more than a
micro-controller with cellular connectivity (3G shield) and two relays
that can be connected to the engine and horn - first to stop the vehicle
and the second to provide an audible warning to anyone in the vicinity
of the vehicle.
It would require a certified electrician to connect the relays to the
various components of the truck; but that is actually the easy part of
this solution - just would be a massive job to retrofit such a device
to all the potential vehicles out there that can be used for terror.
Lastly, security is paramount - would not want unauthorized people to
remotely control the vehicle.
microTLS (µTLS) would be a perfect candidate for this - letting us
focus on the core logic required for the disabling of a vehicle. A lot of
refactoring has been made to the project and I have even build an online
IDE for code editing and compilation of firmware to flash to devices.
The source code to the sketch (without microTLS) is available, could be
