Vehicular Automation
• Vehicular Automation involves the use of
mechatronics, artificial intelligence, and multi-
agent system to assist a vehicle's operator.
• These features and the vehicles employing them
may be labelled as intelligent or smart.
• A vehicle using automation for difficult tasks,
especially navigation, may be referred to as semi-
autonomous.
• A vehicle relying solely on automation is
consequently referred to as robotic or
autonomous.

Autonomy levels
Autonomy in vehicles is often categorized in six levels: The
level system was developed by the Society of Automotive
Engineers (SAE).
• Level 0: No automation.
• Level 1: Driver assistance - The vehicle can control either steering
or speed autonomously in specific circumstances to assist the driver.
• Level 2: Partial automation - The vehicle can control both steering
and speed autonomously in specific circumstances to assist the
driver.
• Level 3: Conditional automation - The vehicle can control both
steering and speed autonomously under normal environmental
conditions, but requires driver oversight.
• Level 4: High automation - The vehicle can complete a travel
autonomously under normal environmental conditions, not requiring
driver oversight.
• Level 5: Full autonomy - The vehicle can complete a travel
autonomously in any environmental conditions.

Vehicle Automation
• Vehicle automation has been one of the
fundamental applications within the ﬁeld of
intelligent transportation systems (ITS) since
the start of ITS research in the mid-1980s.
• For most of this time, it has been generally
viewed as a futuristic concept that is not close to
being ready for deployment.
• However, recent development of “self-driving”
cars and the announcement by car manufacturers
of their deployment by 2020 show that this is
becoming a reality.

Automotive Hacking
• Automotive hacking is the exploitation of
vulnerabilities within the software, hardware,
and communication systems of automobiles.

Automotive Hacking
• Modern automobiles contain hundreds of
on-board computers processing everything
from vehicle controls to the infotainment
system.

Automotive Hacking
• These computers, called Electronic control
units (ECU), communicate with each other
through multiple networks and communication
protocols including the Controller Area
Network (CAN) for vehicle component
communication such as connections between
engine and brake control; Local Interconnect
Network (LIN).

Electronic control units (ECU)

Automotive Hacking
• For cheaper vehicle component
communication such as between door locks
and interior lights;
• Media Oriented Systems Transport (MOST)
for infotainment systems such as modern
touchscreen and telematics connections; and
• FlexRay for high-speed vehicle component
communications such as active suspension
and active cruise control data synchronization.

Media Oriented Systems Transport
(MOST)

Automotive Hacking
• Additional consumer communication systems
are also integrated into automobile
architectures including Bluetooth for wireless
device connections, 4G Internet hotspots,
and vehicle Wi-Fi.

Consumer Communication Systems

Automotive Hacking
• The integration of these various
communications and software systems
leaves automobiles vulnerable to attack.
• Security researchers have begun
demonstrating the multitude of potential
attack vectors in modern vehicles, and some
real-world exploits have resulted in
manufacturers issuing vehicle recalls and
software updates to mobile applications.

Automotive Hacking
• Manufacturers, such as John Deere, have
used computer systems and Digital Rights
Management to prevent repairs by the
vehicle owners, or by third parties, or the
use of aftermarket parts.
• Such limitations have prompted efforts to
circumvent these systems, and increased
interest in measures such as Motor Vehicle
Owners' Right to Repair Act.

Automotive Hacking
• Any car built after 2005 is an 'open door' to
hackers and could be remotely controlled to
obliterate 'millions of civilians', a researcher has
found.
• Even some vehicles up to 17 years old could be
vulnerable to attack and unless car makers fix the
problem deaths in the next five years are
inevitable.
• Hackers may already be causing accidents
without authorities knowing.

without authorities knowing

Automotive Hacking
• The warning was made by Justin Cappos, a
computer scientist at New York University.
• Dr Cappos says this vulnerability should be
treated as an ‘urgent' national security
issue’.

says this vulnerability should be treated as an ‘urgent' national
security issue’.

Automotive Hacking
• Once in the car, Dr Cappos warned hackers
can send messages that stop the brakes
working and turn of power steering.

Automotive Hacking
• 'Components in cars are not good at
understanding where messages come from
and whether they are authentic.'
• In 2016 hackers showed how they were able to
take control of a Jeep Cherokee when it was
moving at high speed.

Automotive Hacking
• Charlie Miller and Chris Valasek, who now
work for Uber, sent false messages to its
internal network, overriding the correct ones.
• That allowed them to do terrifying things
such as making the vehicle turn sharply
while it was speeding down a country road.

Research
• In 2010, security researchers demonstrated
how they could create physical effects and
undermine system controls by hacking the
ECU.
• The researchers needed physical access to
the ECU and were able to gain full control
over any safety or automotive system
including disabling the brakes and stopping the
engine

Research
• In a follow-up research paper published in 2011,
researchers demonstrated that physical access is not
even necessary.
• The researchers showed that “remote exploitation is
feasible via mechanics tools, CD players, Bluetooth,
cellular radio...and wireless communication channels
allow long distance vehicle control, location tracking,
in-cabin audio exfiltration and theft”.
• This means that a hacker could gain access to a
vehicle's vital control systems through almost anything
that interfaces with the automobile's systems.

Players, Bluetooth, Cellular Radio...And Wireless
Communication Channels

Fiat Chrysler UConnect
• UConnect is Fiat Chrysler's Internet-
connected feature which enables owners the
ability to control the vehicle's
infotainment/navigation system, sync media,
and make phone calls.
• It even integrates with the optional on-board
WiFi.

Fiat Chrysler UConnect
• However, susceptibilities in Fiat Chrysler’s
UConnect system, available on over 1.4
million cars, allows hackers to scan for cars
with the system, connect and embed
malicious code, and ultimately, commandeer
vital vehicle controls like steering and
brakes.

General Motors OnStar RemoteLink
App
• The OnStar RemoteLink app allows users
the ability to utilize OnStar capabilities
from their Android or iOS smartphones.
The RemoteLink app can locate, lock and
unlock, and even start your vehicle.

App

App
• The flaw in General Motors’ OnStar
RemoteLink app, while not as extreme as
UConnect, allows hackers to impersonate the
victim in the eyes of the RemoteLink app.
• This means that the hackers can access all of
the features of the RemoteLink app available
to the victim including locating, locking and
unlocking, and starting the engine

Keyless Entry
• The security researcher Samy Kamkar has
demonstrated a device that intercepts signals
from keyless-entry fobs and would allow an
attacker to unlock doors and start a car's
engine.

Case Study : Hackers Remotely Kill a Jeep
on the Highway
• It was the summer of 2015, Andy Greenberg
was driving a Jeep Cherokee in downtown
St. Louis.
• The vents started blasting cold air at the
maximum setting, the radio was blaring at full
volume, and the windshield wipers turned on.

Valasek describe how they compromised the
Jeep Cherokee via a vulnerability in
Uconnect, the vehicle's Internet-connected
entertainment system.

Case Study: Your Car Could Be the Next
Ransomware Target
• Cybersecurity experts say there are plenty
of vulnerabilities for enterprising ransom-
seeking hackers, unless automakers act

Ransomware Target
• The reason cars are such inviting targets for
ransomware hackers is that they’re
increasingly computerized.
• And as automakers have transferred more and
more functions to processors, they've
neglected to install the same levels of
security found in other modern device ssuch
as phones and laptops.

Ransomware Target

Ransomware Target
• “Once you connect the car to the internet,
the entire vehicle becomes a threat surface.
If the auto industry doesn’t adapt, we’ll
continue to see mistakes and potential
vulnerabilities for things like ransomware to
take place,” says Craig Hurst, executive
director of the Future of Automotive
Security Technology Research (FASTR)

Ransomware Target
• The FBI issued a warning last year for the auto
industry to be ever-vigilant about developing
cybersecurity as autonomous technology advances
and as cars become ever-more connected.
• And multiple academic and industry consortiums and
partnerships, as well as for-profit corporations, are
working on the concern.
• One possible scenario involves hackers installing
malware into a vehicle's operating system, perhaps
through an unprotected internet connection, and
locking out the driving functions.

Ransomware Target
• A driver might find his or her car unable to start. A
message pops on the control screen with instructions
for how to pay a ransom to make the vehicle start
again.
• “Cars are becoming computers on wheels,” says Jake
Fisher, director of automotive testing at Consumer
Reports. “As the technologies are added, manufacturers
will have to consider all the possibilities.
• We support the new technology, we’re just making
sure that it is added in a responsible way.”

Ransomware, in general, is a growing criminal concern
because the attacks have been effective and relatively easy to
launch

FBI issued a warning against threats related
to connected vehicle technologies in modern
vehicles

Attacker Model
• The types of attackers that are likely to be
present in an automated vehicle system
• Internal Versus External: The internal attacker
is an authenticated member of the network that
can communicate with other members.
• The external attacker is considered by the
network members as an intruder and, hence, is
limited in the diversity of attacks.
• Nevertheless, she/he can eavesdrop on the
communication

Attacker Model
• Malicious Versus Rational: A malicious attacker
seeks no personal beneﬁts from the attacks, and
aims to harm the members or the functionality of
the network.
• Hence, she/he may employ any means
disregarding corresponding costs and
consequences.
• On the contrary, a rational attacker seeks
personal proﬁt and, hence, is more predictable
in terms of attack means and attack target.

Attacker Model
• Active Versus Passive: An active attacker can generate
packets or signals to perform the attack, whereas a
passive attacker only eavesdrops on the
communication channel (i.e., wireless or in-vehicle
wired network).
• Local Versus Extended: An attacker can be limited in
scope, even if she/he controls several entities (vehicles
or base stations), which make him/her local.
• An extended attacker controls several entities that
are scattered across the network, thus extending
his/her scope.

Attacker Model
• Intentional Versus Unintentional: An
intentional attacker generates attacks on
purpose, whereas an unintentional attack is
a cyber incident that could be generated by
faulty sensors or equipments.

9 Terrifying Ways Hackers Can Control Your
Car
• Cyber security researchers Charlie Miller of
Twitter and Chris Valasek of IOActive used
the latest hacking techniques to hack in to
the electrical systems of a Jeep Cherokee.
They were able to do this without direct
physical access to the vehicle.

9 Terrifying Ways Hackers Can Control
Your Car
• Using the Internet they were able to gain
wireless control of the Jeep Cherokee giving
them access to the Jeep’s entertainment
system, enabling them to relay commands to
its dashboard functions, steering, brakes
and transmission, and they were able to do
all of this remotely 10 miles away from the
vehicle's location.

9 Terrifying Ways Hackers Can Control Your
Car!
• Finding any car via GPS coordinates
• Because Uconnect computers are linked to the
Internet via Sprint’s mobile network, hackers can
use a Sprint mobile device as a Wi-Fi hot spot, along
with a laptop, to scan for possible vulnerable targets on
the Internet. Once an appropriate target has been found,
they are then able to retrieve information about that
vehicle, such as its vehicle identification number, make,
model, IP address, and most scarily, its GPS
coordinates.
• Once the hacker has the GPS coordinates of the
target vehicle, they can then input this data into
Google Maps and track its general location by
placing markers onto the map as the vehicle travels.

hotspot, tracker.

Finding any car via GPS coordinates

Your Car!
• Turning on your car Stereo system remotely
• Imagine you found yourself driving down the motorway
at night alone when suddenly the radio switched on at
full volume, seemingly changing stations with you unable
to control it or switch it off, I think you’d be forgiven for
thinking you were about to be abducted by aliens, but this is
one of the many ways that hackers can manipulate your
vehicle via this exploit.
• Apart from the obvious distraction issues, these types of
attacks could be used to harass and intimidate people
and when you are not aware of who is controlling the
radio this could becomes quite frightening for some
people.

Turning on your car Stereo system
remotely

Your Car!
• Hacking Car Air Conditioning System
• While not the most terrifying aspect of this hack,
it’s also possible to control the vehicles air-
conditioning system by remotely pumping air at
full blast in to the target vehicle. Again, this
would be something of a distraction to drivers,
especially when travelling at high speed.
• This may not seem all that scary but imagine
driving on a very cold winters day, early in the
morning and being blasted by cold air with no
ability to stop it.

Hacking Car Air Conditioning System

Your Car!
• Hacking Car Control System
• It’s a beautifully sunny day and your travelling at
70mph down the motorway when suddenly your
washer fluid starts to continuously spray your
windscreen while your wipers swish from left to
right uncontrollably at full speed.
• While struggling to see through your
windscreen, all confused and a little jumpy,
that’s when your transmission unexpectedly
cuts out and your vehicle stops responding to
your accelerator.

Your Car!
• As the vehicle begins to lose speed rapidly,
you’re terrified to see in your rear view
mirror cars, lorries and other motor
vehicles beginning to rapidly pile up behind
you, swerving and honking their horns when
trying to avoid your sudden speed decrease.
• Well, using this vulnerability, this is exactly
what could happen if a hacker gained
control of your vehicle.

Your Car!
• Shut down you Car Engine
• While your vehicle is in motion, hackers also
have the ability to completely and fully kill the
engine. Leaving you unable to control your
vehicle safely without restarting the engine.
• If this command was given at a critical moment
during your journey, this could cause a dangerous
incident.
• Imagine being on a busy motorway
roundabout when this hack kicks in.

Your Car!
• Hacking Car Brakes
• If you’re not already a little worried, then imagine a
hacker being able to abruptly engage the breaks of
your vehicle while you’re in motion?
• This is where things begin to get really dangerous.
Having the ability to track a vehicle on the move and
then suddenly engage the braking system is quite
terrifying.
• Speeding down the motorway at 70mph when your
brakes unexpectedly and violently kick in is an
extremely dangerous prospect for you and other
motorists.

Your Car!
• Failing your Car Brakes
• This part of the hack is probably the scariest of the lot
and it’s a horrifying thought that a compromised
vehicle could have its brakes completely disabled by
some anonymous hacker miles away in a remote
location while the driver is helpless to stop it.
• This scenario is all too real though and Miller and
Valasek have demonstrated this with chilling
precision.
• Once the hacker has control of the system, there’s
nothing to stop them causing a major incident.

Your Car!
• Threatening the Car Driver through
Display Screen
• Miller and Valasek have also been able to send
images remotely to the in-car digital display.
You can certainly see how this could be abused
and cause issues for the occupants of the
vehicle.

Threatening the Car Driver through
Display Screen

Your Car!
• Hacking Car Steering System
• While travelling at slower speeds and only
while reversing, the hack allows for the control
of the vehicles steering.
• Even though this hack only works at slower
speeds, this is still a dangerous prospect for
both the occupants and pedestrians.

Your Car!
• The list of commands a hacker can issue when in
control of a compromised vehicle is not limited to those
listed above.
• They are also able to manipulate digital readouts for
speed and fuel consumption, honk the horn, query the
vehicle for information and unlock it.
• As hacking techniques get more sophisticated and
pervasive, and as vehicle systems become more
integrated in to the ‘Internet of Things’, it doesn’t
become difficult to imagine that future hacks could
gain more and more control over a vehicles
functions.

Your Car!
• Miller and Valasek aren’t the only ones
working on pointing out these vulnerabilities.
• There has been other research conducted, such as
that undertaken by researchers at the University of
Washington and the University of California who
were able to wirelessly disable locks and brakes
on a Sedan.
• There’s even a ‘Car Hackers Handbook’ out
there.

Steps To Protect Your Car From Hacks

• Keep in touch with your car’s manufacturer
• Update your car’s software
• Store your keyless remote in the fridge (or
faraday bag)
• Turn off your car’s Bluetooth and Wi-Fi when not
in use
• Hide your car’s Wi-Fi password
• Scan USB drives before plugging them into your
car

• Keep in touch with your car’s manufacturer
• Give your auto manufacturer your contact
information so they can reach you about software
updates or vehicle recalls if necessary.
• Or be proactive, and check the National Highway
Traffic Safety Administration (NHTSA) recall
page. Just enter your vehicle identification
number (VIN) there to see if there’s been a recall
for your vehicle.

Keep in touch with your car’s
manufacturer

• Update your car’s software
• Outdated software can contain bugs that
hackers can exploit to steal your private data or
take control of your car.
• So just as you’d check your computer for
software updates, be sure to keep an eye out
for notices from your auto manufacturer, and
bring your car in for updates as soon as they’re
available.

• Store your keyless fob in the fridge
• Or get a faraday bag.
• Because in a matter of seconds, thieves can break
into your car by amplifying the signal from your
keyless remote and tricking the car into thinking
you’re nearby.
• If Your Keyless Fob Is In A Faraday Bag (Or Your
Refrigerator), Then Its Signal Will Be Blocked,
Preventing Criminals From Hacking Open Your
Car Doors.

Store your keyless fob in the fridge
Or get a faraday bag

• Turn off your car’s Bluetooth and Wi-Fi
when not in use
• An open wireless connection could allow
criminals to walk up to an unpatched car,
connect to its entertainment system, and take
control of one or more parts of the vehicle

Turn off your car’s Bluetooth and Wi-Fi when
not in use

• The FBI warns, “Vulnerabilities may exist within a
vehicle’s wireless communication functions, within a
mobile device – such as a cellular phone or tablet
connected to the vehicle via USB, Bluetooth, or Wi-Fi
– or within a third-party device connected through a
vehicle diagnostic port. In these cases, it may be
possible for an attacker to remotely exploit these
vulnerabilities and gain access to the vehicle’s
controller network or to data stored on the vehicle.”
• So if you’re not using your car’s Bluetooth or Wi-Fi,
it’s best to switch them off.

• Hide your car’s Wi-Fi password
• This one’s simple. If your car has its own Wi-
Fi, be sure to keep the password hidden.
Leaving it in your glovebox could expose you
to attack if your car is ever broken into.

Hide your car’s Wi-Fi password

• Scan USB drives before plugging them into
your car
• An infected USB drive could contain
malicious code designed to compromise your
car. So be sure to scan any USB drive before
plugging it into your car.

Scan USB drives before plugging them
into your car

Conclusion
• These types of attacks are only likely to get more varied
and sophisticated and with some 470,000 plus estimated
Crysler vehicles already vulnerable to these types of
attack, not to mention the very real possibility of other
manufacturers models also being vulnerable to similar
exploits it’s extremely important that both the auto industry
and customers take note.
• Crysler has issued a security patch which can be
downloaded at their website by entering your Vehicle
Identification Number (VIN) but this is a manual
process that requires you to download the patch and
update your Uconnect System via a USB drive.
Alternatively, you can take your car to a dealer to get the
update.

Cyber-attacks On Internet-connected
Cars

Conclusion
• This type of patching requires that the customer be aware of
the vulnerability though, which means that moving forward,
the responsibility for updating the security of the vehicles
electronic system lies with customers.
• There needs to be a better, more secure way of
automating vehicle updates on these types of systems.
• In a hyper connected world, cyber attacks and cyber
threats are an ever-growing concern for businesses and
consumers alike and the research conducted by Miller
and Valasek highlights the need for more individuals to
be working in IT security jobs, specifically cyber
security.
