any device that's connected to the
internet can be hacked but just How
likely is it that a hacker could take
over the computer system of say an
airport or a power grid making stuff
host David POG met with cyber security
expert Terry Benzel to find out about
the risks of a major Cyber attack so how
vulnerable are we right now well
unfortunately we're we're entirely
vulnerable people in my community call
it the Cyber Pearl Harbor and for us
it's not if there'll be a cyber Pearl
Harbor it's when there'll be a cyber
Pearl Harbor but I haven't heard of
anything approaching a Pearl Harbor
scale that you're making a big leap
there but we hadn't seen an airplane fly
into a World Trade Center yet either
right can we wait for that no we can't
Benzel runs a project called deter come
on in let me show you the deter lab
facility wa it's a one-of-a-kind
practice internet for cyber security
researchers all over the world the
system consists of around 500 linked
computers that can emulate hundreds of
thousands more researchers can use deter
to Stage cyber war games without harming
the real internet one form of cyber
Attack under investigation is the
distributed denial of service attack in
this scheme a cyber criminal gets
hundreds of thousands of users to
download an innocent looking message
that contains malware basically V viral
software once infected the computers
form a vast robotic Network or a botn
net which the hacker controls the hacker
can then tell each computer to send a
useless request to a particular website
or network like one for a power grid
these requests overload the site server
causing the site to deny service to all
of its legitimate users Ted Faber stages
one of these attacks on the deter system
those little booms there as anyone from
war games will tell you are not good
each dot represents a whole bunch of
attacks right exactly so and more dots
along a given path the more attacks are
going from here to there and where are
you where's the website this is the
victim right here here it looks like
they're coming thicker and faster now
each time you get infected you also
start trying to infect your neighbors
eventually the Box turns red indicating
that the server can't handle the huge
amounts of traffic to the site this type
of attack temporar L shut down the web
service of scores of US Banks in late
2012 and early 2013 but using deter
Faber canest a cyber defense strategy
what I'm going to do now is Rerun the
same game except these other two guys
who we had here constant blue they're my
backup servers he brings two additional
servers online if you look close you can
start to see these packets inbound to
this guy packets inbound to this bottom
guy so now the botn Nets are attacking
the backups too yep but notice that
because the attack destination is spread
out over three nodes they don't get as
hot oh you're dividing up the load of
handling all these useless requests
right you can see we're all pretty much
the same color again we seem to have
spread the load out and continued to
serve people this time around the
victim's website survives but next time
the hackers may come up with a new kind
of attack in order to win this digital
arms race detur is educating the next
generation of cyber researchers so they
can predict the bad guy's next move with
enough Minds on the job perhaps deter
can prevent a cyber Pearl Harbor
