This is a lot of ones and zeros.
It's what we call binary information.
It's how they store information.
everything it is that computers do.
I'm a cybersecurity researcher,
which means my job is to sit down with this information
to try to understand what all the ones and zeroes mean.
Unfortunately for me, we're not just talking
about the ones and zeros I have on the screen here.
We're not just talking about a few pages of ones and zeros.
We're talking about billions and billions
more than anyone could possibly comprehend.
Now, as exciting as that sounds,
when I first started doing cyber —
(Laughter) —
when I first started doing cyber, I wasn't sure
that sifting through ones and zeros
was what I wanted to do with the rest of my life,
was keeping viruses off of my grandma's computer,
it was keeping people's Myspace pages from being hacked,
and maybe, maybe on my most glorious day,
it was keeping someone's credit card information from being stolen.
but that's not how I wanted to spend my life.
I soon found out that my idea of cyber
In fact, in terms of national security,
keeping viruses off of my grandma's computer
was surprisingly low on their priority list.
And the reason for that is cyber
is so much bigger than any one of those things.
Cyber is an integral part of all of our lives,
because computers are an integral part of all of our lives,
even if you don't own a computer.
Computers control everything in your car,
from your GPS to your airbags.
They're the reason you can call 911
and get someone on the other line.
They control our nation's entire infrastructure.
They're the reason you have electricity,
Computers control our military equipment,
everything from missile silos to satellites
All of these things are made possible
and therefore because of cyber,
and when something goes wrong,
cyber can make all of these things impossible.
A big part of my job is defending all of these things,
but once in a while, part of my job is to break one of these things,
because cyber isn't just about defense,
We're entering an age where we talk about
In fact, so great is the potential for cyber offense
that cyber is considered a new domain of warfare.
It's not necessarily a bad thing.
On the one hand, it means we have whole new front
on which we need to defend ourselves,
it means we have a whole new way to attack,
a whole new way to stop evil people
So let's consider an example of this
that's completely theoretical.
Suppose a terrorist wants to blow up a building,
and he wants to do this again and again
So he doesn't want to be in that building when it explodes.
He's going to use a cell phone
Now, it used to be the only way we had
was with a hail of bullets and a car chase,
but that's not necessarily true anymore.
We're entering an age where we can stop him
because whether he knew it or not,
as soon as he decided to use his cell phone,
he stepped into the realm of cyber.
A well-crafted cyber attack could break into his phone,
disable the overvoltage protections on his battery,
drastically overload the circuit,
cause the battery to overheat, and explode.
No more phone, no more detonator,
all with the press of a button
It all comes back to those ones and zeros.
Binary information makes your phone work,
and used correctly, it can make your phone explode.
So when you start to look at cyber from this perspective,
spending your life sifting through binary information
starts to seem kind of exciting.
But here's the catch: This is hard,
Think about everything you have on your cell phone.
You've got the pictures you've taken.
You've got the music you listen to.
You've got your contacts list,
your email, and probably 500 apps
you've never used in your entire life,
and behind all of this is the software, the code,
and somewhere, buried inside of that code,
is a tiny piece that controls your battery,
and that's what I'm really after,
but all of this, just a bunch of ones and zeros,
and it's all just mixed together.
In cyber, we call this finding a needle in a stack of needles,
because everything pretty much looks alike.
I'm looking for one key piece,
but it just blends in with everything else.
So let's step back from this theoretical situation
of making a terrorist's phone explode,
and look at something that actually happened to me.
Pretty much no matter what I do,
my job always starts with sitting down
with a whole bunch of binary information,
and I'm always looking for one key piece
In this case, I was looking for a very advanced,
inside of a billion ones and zeroes.
Unfortunately for me, I didn't know
I didn't know quite what it would look like,
which makes finding it really, really hard.
When I have to do that, what I have to do
is basically look at various pieces
try to decipher each piece, and see if it might be
So after a while, I thought I had found the piece
It seemed to be about right, but I couldn't quite tell.
I couldn't tell what those ones and zeros represented.
So I spent some time trying to put this together,
but wasn't having a whole lot of luck,
I'm going to get through this,
I'm going to come in on a weekend,
until I figure out what this represents.
So that's what I did. I came in on a Saturday morning,
and about 10 hours in, I sort of had all the pieces to the puzzle.
I just didn't know how they fit together.
I didn't know what these ones and zeros meant.
I started to get a better picture of what was there,
but I had a creeping suspicion
was not at all related to what I was looking for.
By 20 hours, the pieces started to come together
and I was pretty sure I was going down
but I wasn't going to give up.
I figured out exactly what I was looking at,
and I was right, it wasn't what I was looking for.
I spent 30 hours piecing together
the ones and zeros that formed a picture of a kitten.
(Laughter)
I wasted 30 hours of my life searching for this kitten
with what I was trying to accomplish.
So I was frustrated, I was exhausted.
After 30 hours in the lab, I probably smelled horrible.
But instead of just going home
and calling it quits, I took a step back
and asked myself, what went wrong here?
How could I make such a stupid mistake?
I'm really pretty good at this.
Well I thought, when you're looking at information at this level,
it's so easy to lose track of what you're doing.
It's easy to not see the forest through the trees.
It's easy to go down the wrong rabbit hole
and waste a tremendous amount of time
We were looking at the data completely incorrectly
This is how computers think, ones and zeros.
but we've been trying to adapt our minds
so that we can understand this information.
Instead of trying to make our minds fit the problem,
we should have been making the problem
because our brains have a tremendous potential
for analyzing huge amounts of information,
So what if we could unlock that potential
to the right kind of information?
I sprinted out of my basement lab at work
which looked pretty much the same.
The main difference is, at work,
I'm surrounded by cyber materials,
and cyber seemed to be the problem in this situation.
At home, I'm surrounded by everything else I've ever learned.
So I poured through every book I could find,
every idea I'd ever encountered,
to see how could we translate a problem
from one domain to something completely different?
what do we want to translate it to?
What do our brains do perfectly naturally
We have a tremendous capability to analyze visual information.
We can combine color gradients, depth cues,
all sorts of these different signals
into one coherent picture of the world around us.
So if we could find a way to translate
these binary patterns to visual signals,
we could really unlock the power of our brains
So I started looking at the binary information,
and I asked myself, what do I do
when I first encounter something like this?
And the very first thing I want to do,
the very first question I want to answer,
I don't care what it does, how it works.
All I want to know is, what is this?
And the way I can figure that out
sequential chunks of binary information,
and I look at the relationships between those chunks.
When I gather up enough of these sequences,
I begin to get an idea of exactly
what this information must be.
blow up the terrorist's phone situation.
This is what English text looks like
This is what your contacts list would look like
It's really hard to analyze this at this level,
but if we take those same binary chunks
that I would be trying to find,
translate those relationships,
This is what English text looks like
from a visual abstraction perspective.
it shows us all the same information
that was in the ones and zeros,
but show us it in an entirely different way,
a way that we can immediately comprehend.
We can instantly see all of the patterns here.
It takes me seconds to pick out patterns here,
but hours, days, to pick them out
It takes minutes for anybody to learn
what these patterns represent here,
but years of experience in cyber
to learn what those same patterns represent
lower case letters followed by lower case letters
This is upper case by upper case,
upper case by lower case, lower case by upper case.
This is caused by spaces. This is caused by carriage returns.
We can go through every little detail
of the binary information in seconds,
as opposed to weeks, months, at this level.
This is what an image looks like
But this is what it looks like
This is what your music looks like,
but here's its visual abstraction.
this is what the code on your cell phone looks like.
This is what I'm after in the end,
but this is its visual abstraction.
If I can find this, I can't make the phone explode.
I could spend weeks trying to find this
but it takes me seconds to pick out
a visual abstraction like this.
One of those most remarkable parts about all of this
is it gives us an entirely new way to understand
new information, stuff that we haven't seen before.
So I know what English looks like at a binary level,
and I know what its visual abstraction looks like,
but I've never seen Russian binary in my entire life.
It would take me weeks just to figure out
what I was looking at from raw ones and zeros,
but because our brains can instantly pick up
and recognize these subtle patterns inside
we can unconsciously apply those
So this is what Russian looks like
Because I know what one language looks like,
I can recognize other languages
even when I'm not familiar with them.
This is what a photograph looks like,
but this is what clip art looks like.
This is what the code on your phone looks like,
but this is what the code on your computer looks like.
Our brains can pick up on these patterns
in ways that we never could have
from looking at raw ones and zeros.
But we've really only scratched the surface
of what we can do with this approach.
We've only begun to unlock the capabilities
of our minds to process visual information.
If we take those same concepts and translate them
into three dimensions instead,
we find entirely new ways of making sense of information.
In seconds, we can pick out every pattern here.
we can see the cross associated with code.
We can see cubes associated with text.
We can even pick up the tiniest visual artifacts.
Things that would take us weeks,
months to find in ones and zeroes,
in some sort of visual abstraction,
and as we continue to go through this
and throw more and more information at it,
what we find is that we're capable of processing
just by using our brain's built-in ability
So this is really nice and helpful,
but all this tells me is what I'm looking at.
So at this point, based on visual patterns,
I can find the code on the phone.
But that's not enough to blow up a battery.
The next thing I need to find is the code
that controls the battery, but we're back
to the needle in a stack of needles problem.
That code looks pretty much like all the other code
So I might not be able to find the code that controls the battery,
but there's a lot of things that are very similar to that.
You have code that controls your screen,
that controls your buttons, that controls your microphones,
so even if I can't find the code for the battery,
I bet I can find one of those things.
So the next step in my binary analysis process
is to look at pieces of information
that are similar to each other.
It's really, really hard to do at a binary level,
but if we translate those similarities to a visual abstraction instead,
I don't even have to sift through the raw data.
All I have to do is wait for the image to light up
to see when I'm at similar pieces.
I follow these strands of similarity like a trail of bread crumbs
to find exactly what I'm looking for.
So at this point in the process,
responsible for controlling your battery,
but that's still not enough to blow up a phone.
is understanding how that code
very subtle, very detailed relationships
within that binary information,
when looking at ones and zeros.
But if we translate that information
into a physical representation,
we can sit back and let our visual cortex do all the hard work.
It can find all the detailed patterns,
all the important pieces, for us.
It can find out exactly how the pieces of that code
work together to control that battery.
All of this can be done in a matter of hours,
would have taken months in the past.
in a theoretical blow up a terrorist's phone situation.
I wanted to find out if this would really work
So I was playing around with these same concepts
with some of the data I've looked at in the past,
and yet again, I was trying to find
a very detailed, specific piece of code
inside of a massive piece of binary information.
So I looked at it at this level,
thinking I was looking at the right thing,
the connectivity I would have expected
for the code I was looking for.
In fact, I'm not really sure what this is,
but when I stepped back a level
and looked at the similarities within the code
I saw, this doesn't have similarities
like any code that exists out there.
I can't even be looking at code.
In fact, from this perspective,
I could tell, this isn't code.
This is an image of some sort.
it's not just an image, this is a photograph.
Now that I know it's a photograph,
I've got dozens of other binary translation techniques
to visualize and understand that information,
so in a matter of seconds, we can take this information,
shove it through a dozen other visual translation techniques
in order to find out exactly what we were looking at.
it was that darn kitten again.
because we were able to find a way
to translate a very hard problem
to something our brains do very naturally.
no more hiding in ones and zeros.
For me, it means no more wasted weekends.
For cyber, it means we have a radical new way
to tackle the most impossible problems.
in the evolving theater of cyber warfare,
now have the ability to become first responders
we've unlocked the means to stop the bad guys.
