DECEPTION
IN CYBERSPACE
Bill
Hutchinson and Mat Warren
We
live in a world of illusion. Our senses are limited
and our brain interprets our imperfect sensory inputs
in ways based on our education, intelligence, cultural
background, and our immediate surroundings, past experiences,
mood, and a multitude of other factors. We deceive
ourselves every day of the year. However, this article
is about how others deliberately deceive us, sometimes
using the very limitations mentioned before. It will
concentrate on deception in cyberspace but the principles
are relevant in many situations and using many media;
most of which are not hi-tech.
Manipulating
data to produce outcomes desired by the manipulator
has been routinely practiced since the dawn of history.
From a soldier's camouflage suit to the company brochure
skilfully crafted by corporate spin-doctors, individuals
and organisations choose data (signals) to send out
into the world, which suits the image they want to
be portrayed. Faked documents and photographic images
have been faked to alter history for many. However,
the advent of digital data has made manipulation of
images, text, sounds, and even smells much easier.
Innovations in the creation perceptual peripherals
has made the impact of manipulated data reach a profound
level.
Principles
of Deception
For
our purposes, deception is defined as the deliberate
alteration of data or a situation's context to promote
a desired outcome. Therefore, it does not include
self-delusion, or a person's natural tendency to use
mental models to interpret things in an individual
way. The definition places emphasis on a second party
being involved, where that person or organisation
is consciously trying to create deception.
The
word 'deception' tends to infer a negative motive.
For instance the following words were derived from
the Thesaurus of the MS Word package used to create
this document: illusion, sham, stratagem, hoax, cheat,
lie, delude, trick, betray, swindle, hoodwink, defraud,
con, dupe, and mislead. Many of these words indicate
an action and/or a negative motive. However, it is
the motive, which ultimately decides the ethics of
a situation where a deception is used.
However,
to really understand deception, it is necessary to
define the words: 'data', 'information', and 'knowledge'.
There are many definitions of these terms but for
our purposes, the best is derived form Boisot . He
developed a model where data is defined as
the attribute of a 'thing' such as, its colour, shape,
or its value. Whereas, knowledge is an attribute
of an 'agent' (usually this means a human, although
it can be argued that intelligent machines can have
knowledge). Knowledge is a product of experiences,
education, age, gender, culture, and many of the other
factors that make up individuals. He further argues
that humans derive information by using their
knowledge to select appropriate data provided to them
to construct it. Thus, human information is a product
of the data supplied to a human plus their interpretation
of it in a particular context. These definitions imply
that information is personal. No information is 'true',
just an interpretation. We might agree on the 'truth'
about something simple such the colour of a carpet,
but be at odds about the 'truth' of the causes of
the Gulf War despite limited knowledge of all the
data, and propaganda (data trying to mode the context
of 'facts').
To
execute a deception, one or more of these elements
(data, knowledge, or context) must be manipulated.
This can be achieved by controlling the data available
to a human by depriving, adding, deleting, or modifying
its contents, or arranging the time and place it is
delivered (if ever). It is a bit trickier but the
context in which the data is interpreted can be manipulated.
Changing the knowledge base is also possible but is
usually long term and is best left to the great socialising
factors: family, religion, the mass media, peers,
and the education system. Give me the boy until he
is seven...and I'll show you the man!
Thus
to deceive, data can be manipulated to allow the 'targeted'
person(s) only to have access to the subset of data
which will provide the best perceived outcomes for
the deceiver. The data is then interpreted using mental
models (knowledge), which can be affected directly
by other activities such as propaganda and perception
management (such as advertising campaigns). This is
usually a long-term process. However, the context
within which the mental models make the human decide
an outcome can also be influenced by enhancing/decreasing
environmental signals. Of course, the ultimate aim
is to alter behaviour. Thus, just changing thought
patterns may not be enough; changing behaviour is
more difficult
Deception
can be classified into two types :
- Hiding
the real;
- Showing
the false.
Of
course, 'showing the false' involves 'hiding the real'
but not the other way around. 'Hiding' can further
be divided into 'Masking', 'Packaging', and 'Dazzling'.
'Showing' can be divided into 'Mimicking', 'Inventing',
and 'Decoying'.
Masking
occurs when something blends into the background.
This is typical of camouflage. Repackaging occurs
when something is perceived to be something else.
Dazzling occurs when the target knows you are there
but is confused by overwhelming signals are sent out.
An octopus squirting ink into a predator momentarily
confuses the attacker. This can be used to escape
or a diversion to allow an attacker to strike from
a different point (a feint).
Mimicking
(spoofing) involves the display of something, which
looks like something else. It is similar to masking
but not attempt to hide is made, just to hide the
reality of what is there. Inventing creates a new
reality. Thus a colourful reef fish with a large spot
and its rear is creating the impression to an attacker
that its eye is mush further back than it is. When
it attacks the predator makes for the 'wrong end'
of the fish giving it an ability to dart forward and
escape. Most fashion clothing, uniforms, and make-up
are designed to create a 'new, world reality'. Decoying
openly shows something, which it is not. For example,
dummy tanks used successfully by the Serbs in the
recent Balkans' conflict to confuse attack aircraft.
A
successful deception needs planning. The deceiver
needs to know why, what, who, when, and how. There
must be an objective, a target and a story to tell.
The desired outcomes must be known, as should be the
reasons for doing it in the first place. The type
of data: environmental, machine, or, direct digital
will determine the easiest and most effective method
at any given time. This process is ongoing. Situations
are dynamic, and so the methods used must be as well.
Of
course, there are two sides to a deception: the deceiver
and the deceived. Individuals and organisations should
have vibrant processes to ensure the integrity of
the data received, processed, stored, and used. There
should also be an awareness of the ability of others
to manipulate perceptions. As such, the humans using
the data should be interpret them in the context chosen
by themselves or the organisation they represent.
The sources of data should always be established and
verified.
Deception
on the World Wide Web
The
digital nature of Web sites and their almost universal
accessibility make them prone to attack. Some examples
of the types of deception listed above can be illustrated.
However, it should be noted that a really successful
deception is one that is unrecognised. Therefore,
the examples below are not truly successful deceptions
but do serve to illustrate the point. Many of them
are obvious and might cause embarrassment but not
deception. Subtle attacks are far more destructive.
The changing of a person's photographic image, or
the insertion of small pieces of text are techniques
that may go undetected until the damage has been caused.
For instance, one can only speculate about the damage
that could be caused by inserting the word 'not' into
an employment advertisement stating 'Applications
from women especially welcome'.
The
concept of repackaging can be practiced on the Web.
Here the user is fooled into believing that something
is what it is not. There are numerous sites that purport
to be what they are not. A Kurdish Liberation Movement
site will appear authentic but really hold messages
and images that further the cause of the nation state
of Turkey. Many terrorist groups use innocuous sites
for passing messages to their membership. Many deceptions
on the Web camouflage their real intent. A common
way to spread computer virus is to have an attachment
to an e-mail message apparently with desirable contents,
which is just an unwanted or maybe destructive program.
Propaganda
and disinformation have always been a part of making
a point. The contemporary term is 'perception management'
and, as Web sites become the 'faces' of organisations
to the world, more care will be needed to ensure that
the data and its presentation on these sites give
the desired image. Also, it is important that part
of the corporate database shown does not allow its
image to be tarnished or its secrets revealed.
Dazzling
is meant to provide data overload to the victim. The
target's resources are thus used up in coping with
the attack rather than its normal operating activities.
Much obvious and malicious hacking is of this type.
Its intent is to embarrass and interrupt operations.
'Spamming' is one way to give this effect. Dazzling
is also used as a feint to detract targets from the
real attack. Therefore, an attacker might flood a
site with emails, or obvious denial of service attacks
but be really trying to implant a rogue piece of code,
as the system administrators are busy coping with
the dazzling attacks.
Deception
on the Web can be divided into passive and active.
Many sites contain images that are there to invoke
emotional responses to further the cause of their
creators. As it is easy to set up a site, the contents
of all but a few should be treated with caution. Victims
of a particular illness might desperately search for
data on their condition. Charlatans abound and their
motives for doing what they do might be financial
or just plain 'loopy'. We can be whatever we want
to be at our Web site, or on a chat line. Computer
Cams might add to our sense that what we are seeing
is authentic, but we are easily fooled. On the Internet,
emails are broadcast to people stating that a general's
son is about to be executed in La la Land. Money will
save his life but must be sent within the next week.
It is amazing how many people actually send money.
The authors have knowledge of an intelligent, mature
individual who replied to one of these requests. He
ended up getting threatening phone calls and an apparent
debt of a quarter of a million dollars. It took a
visit to the police and a change of telephone number
to rid this person of unwelcome attention. It is also
of no surprise that the most effective way into a
computer system is not technical wizardry but 'social
engineering'. The manipulation of others by convincing
them that you are authentic either in person or on
the telephone.
The
means of deception in cyberspace are numerous; the
table below lists some of the more common types.
| Deception |
Description |
| Honeypots/Honeynets |
Apparently
authentic web sites but really sites to trap hackers/crackers.
Used to analyse attack strategies used by hackers
|
| Propaganda |
Sites
used to espouse a certain political, religious
beliefs. They are often apparent, but many present
'facts' which can lead to deception occurring |
| Spamming |
Flooding
a target site with data. This might just be a
nuisance, or a distraction for another attack.
|
| Spoofing |
Messages
appear to be derived form one source but are form
another. Used to give credibility to an e-mail
message, or to obtain network privileges. |
| Viruses |
Malicious
programs that pretend to be something else, by
embedding themselves into innocuous code. |
| Steganograhy |
The
art of hiding one message within another. For
instance, an image file might contain a message,
whilst the image might be displayed the hidden
message goes undetected. |
| Virtual
reality |
The
combination of software and I/O devices designed
to create a whole perception not necessarily based
on the physical world. |
| Encryption |
Encoding
a message to make it unintelligible to those who
do not have the key. |
| Lying |
Sending
deliberately false data (eg market information)
to create an effect |
Beyond the Present
In
the early 1990's, when the French philosopher, Jean
Baudrillard, wrote a series of articles called 'The
Gulf War Did Not Take Place', he did not mean that
the events of that conflict did not occur, but that
the reality of the situation had been changed by the
media. The perception that what happened in the Gulf
was a 'real war' was controlled by the data and context
set by the media and fed to the consumer. The implication
is that our senses relating the 'real' world to our
brains is no longer the primary determinant of perception.
The development of wireless technologies and its associated
software and wearable hardware has brought the spectre
of the true human machine. A mobile set of gadgets
could allow you to accentuate your senses (Marks,
2000; Gershendfeld, 1999; Kurzwell, 1999). Some examples
are:
- Infra-red/star
light vision;
- Ability
to 'smell' other humans in your vicinity;
- Face
recognition software that could identify the person
standing in front of you then
-
display their name and details either visually or
by voice;
- The
ability to find out where you are, and call up a
map to be displayed on your retina;
- The
ability to send real-time movie images of your own
situation, and so on.
Who
could resist these extra abilities? The applications
for these technologies are enormous. Yet so is the
ability to deceive. As human become almost totally
dependent on digital data for their personal operational
lives the consequences of deception increase exponentially.
Yet,
the implications of contemporary technological development
take digital data into another realm. At one level,
the ability to create virtual world where you can
have a conversation with someone in Sydney whilst
you are in Prague, and at the same time touch and
feel that person in the bubble of a virtual world
can stretch the abilities of those who deceive but
also provide enormous potential.
An
even higher level of dependence is the creation of
the true human-machine - the cyborg. The physical
merging of mind and machine lifts the data processed
by our brains from photons, volatile chemicals, and
pressure to pure digital data. In the UK, a married
couple have implanted microchip directly into their
nervous systems (under the arm) to be able to 'feel'
their respective 'feelings'. Digital data now totally
replaces 'natural' inputs; this is truly the digital
person. Some of the consequences of this digital world
where many humans are networked and receive purely
digital data into their nervous systems are easy to
imagine. Feeding 'false' or manipulated data into
a system such as this would have enormous implications.
Ironically in a networked world, the digital enhancement
of the individual would make each one vulnerable to
being turned into the clone (in terms of behaviour)
of everyone around. Whilst the previous argument sounds
more like science fiction, many of the principles
are not. In this case, digital data is your
world.
The
development of wireless technologies has created a
new, distance free world. The data stored is a part
of you. Recently, an IRA member was convicted
because his mobile telephone logs showed him to be
at certain places at certain times. The US government
now insists that all mobile telephones must be able
to be located to a few metres. Hence, your very position
is always known, or is it? Here the mobile telephone
became that person. It can be reversed, if you want
an alibi give someone else your telephone and go to
some other place. 'You' are then not where really
are. The mobile phone (the 'other' you) is somewhere
else.
Conclusion
Deception
is a part of life, and the Internet/World Wide Web
are just new tools for its practice. The flexibility
of digital data is one of its great benefits yet,
this very flexibility, makes the alteration of data
so easy.
Security
can be defined as the function that ensures the survivability
of an organisation or individual, and it is within
this role that deception should be studied. Knowledge
of the methods of deception is essential to protect
you or your organisation's interests. The authors
carried out a survey of Australian information technology
managers to determine perceptions of threats to their
organisations . Interestingly, 66% thought there was
no threat of attack from competitors. This complacency
might be reflective of high ethical behaviour in business
or a dangerous ignorance of the risks involved.
On
the other side of the coin, deception is also a part
of strategy. Howard states that force is the strategy
of the strong, and deception the strategy of the weak.
In this case, the Internet has opened up the world
to potential, 'weak' attackers. However, the use of
deception as tool in individual and organisational
survival should also not be overlooked.
In
a world where surveillance is the order of the day
and is entrenched in all facets of life, deception
may be the only way to escape the watchful eyes of
those who wish to control. Devices watch citizens
at work and at play. The locations of people, both
in real time and historically can be determined by
their mobile telephone records. Financial, tax, medical,
insurance, social security, purchase records...any
number of personal data can be integrated and processed.
In this insidious world of data collection, the most
effective response might just be another massive deception.
May the force of truth be with you!
