Memorandum by APACS
APACS welcomes this opportunity to provide evidence
to the Science and Technology Committee on the subject of personal
Internet security. APACS is the UK trade association for payments
and for those institutions that deliver payment services to customers.
It provides the forum for its members to come together on non-competitive
issues relating to the payments industry. We currently have 31
members whose payment traffic volumes account for approximately
97 per cent of the total UK payments market.
APACS co-ordinates a range of banking industry
activities aimed at tackling payment-related fraud. One of the
most visible recent initiatives has been the introduction of Chip
and PIN. APACS also co-ordinates the banking industry's efforts
to combat online banking, payment and identity fraud. APACS and
its members have many years of experience in gaining an understanding
of the threats faced by individuals using online services, and
in developing effective strategies to mitigate those threats.
SUMMARY
The level of threat to personal security on
the Internet is increasing. It is driven by a combination of factors,
each of which is contributing to a rapidly escalating problem
which, if not effectively tackled, threatens long-term damage
to the increasingly important online economy. These factors include,
but are not limited to:
the increasing sophistication of
social engineering and technical threats which are mostly aimed
at private individuals;
the commoditisation of these skills
and technologies;
the increasing involvement of cross-border
organised crime gangs in operating fraud and money laundering
operations, and in funding the development of skills and technologies
used to attack individuals;
the challenge of providing effective
information and advice to the most vulnerable; and
the challenge of mounting an effective
cross-border law enforcement response.
Our response describes the range and severity
of threats to personal online security, and suggests a number
of areas where the banking industry feels that valuable improvements
could be made.
DEFINING THE
PROBLEM
The nature of the threat to private individuals
Online banking and payments are hugely popular
activities in the UK. APACS research estimates that nearly 16
million people use online banking services in the UK, and nearly
27 million now shop online. The Internet has therefore rapidly
become an extremely important and attractive channel for payments
and access to sensitive financial information. These are services
that consumers value highly, and financial institutions are keen
to meet this demand in a secure manner.
The security of internet-based services is paramount
to the banking industry, and banks have invested heavily in protecting
their IT infrastructure. These measures have been highly successful
in protecting banks' customer data from direct attack. However
the very strength of protection around banking systems has led
criminals to target the weak link in the chainthe customers
themselves.
Criminals have also seen the success of the
Internet, and have begun to exploit its weaknesses for their own
ends. They are interested in obtaining security credentials and
other information that enables them to obtain value. Such information
includes usernames, passwords, card numbers, addresses, telephone
numbers and memorable data such as mothers' maiden names. Criminals
generally try to steal these credentials in one of two ways:
By asking for it: Phishing emails
are a very visible example of so-called "social engineering".
They are unsolicitedsent out at random by criminals, usually
hundreds of thousands or millions at a timethat often pretend
to be from a recognised financial institution. The emails ask
the recipient to click on a link that takes them to a web site
that may look identical to a genuine bank site, but whose sole
purpose is to fool visitors into handing over their security credentials.
Having obtained the information, criminals are then able to impersonate
a customer and log into their bank account to withdraw funds,
or use the information to carry out other types of identity theft.
APACS has monitored the growth of phishing since
it first hit the UK banking industry in September 2003. The sophistication
of the emails has evolved considerably over time, including the
emergence of personalised phishing, where name and address details
of the recipient are included in the email. Attackers typically
obtain these personal details through identity theft, for example
by stealing online merchants' customer databases. To date we have
not seen any evidence to suggest that bank customer databases
have been compromised, and apart from the personal details they
contain, such phishing emails are still essentially sent out at
random.
APACS has also monitored the rapid growth in
phishing incidents (measured as the number of spoof bank sites
set up by criminalsnot by spam run volume) aimed at UK
banks over the past few years. In January 2005 we recorded 18
such incidents, compared to 1,513 in September 2006an increase
of over 8,000 per cent in less than two years.

Phishing is not the only form of social engineering
used to steal personal information.APACS expects telephone-based
scams to expand, driven by the rapid takeup of Voice-over-IP (VOIP)
services that allow fraudsters cheap and largely anonymous access
to any UK phone number. APACS has monitored a number of cases
of so-called "Vishing" over the past few months.
By spying on the consumer: There
is strong evidence that criminal gangs involved in phishing scams
are increasingly using highly sophisticated software to steal
data, commonly referred to as trojans, malicious software or "malware".
Organised gangs have created underground markets to obtain information
from corrupt researchers on computer security holes, which their
own software coders can then turn into effective malware. The
objective of malware is the same as phishingto obtain personal
and security information. The difference is that the victim may
remain completely unaware that anything is wrong until a fraud
has occurred. Modern malware is capable of infecting even well
protected computers, and of spying on user activities such as
keypresses, mouse movements and Internet browser sessions.
By way of example, Torpig/Haxdoor is a particularly
sophisticated example of malware that is being investigated by
the banking industry. Once infected by Torpig, a victim's computer
waits for the victim to navigate to any one of several hundred
bank web sites before inserting false login pages which invite
customers to input a wide range of information. Torpig is capable
of being updated automatically, and thousands of victim machines
may be managed by a single criminal.
Scale of the threat
It is important to appreciate that online identity
theft scams are largely run by organised crime gangs, most of
them operating on a trans-national basis. Through collaboration
with law enforcement, we have been able to establish that most
attacks targeting banking customers emanate from a number of gangs
operated out of eastern Europe, although other organised gangs
are increasingly becoming involved including ones based in Nigeria.
Losses to the banking industry due to online
banking fraud grew 90 per cent in 2005 to £23.2 million.
Losses for 2006 are expected to increase by a similar percentage.
All banks currently choose to refund customers whose accounts
have been compromised, except in exceptional circumstances such
as first-party fraud.
The introduction of Chip & PIN to credit
and debit cards, and the high level of security that it offers,
has led to fraudsters migrating their card fraud efforts to channels
where Chip & PIN protection is not availablein other
words to Internet and phone transactions. In 2005 card-not-present
fraud rose 21 per cent to £183.2 million (of which an estimated
£117.1 million was Internet-based), and there is evidence
that organised fraudsters are actively seeking to obtain card
details online, using many of the same techniques aimed at online
banking users.
APACS estimates that the wider cost of identity
theft against bank customers was around £30.5 million in
2005. This is made up of a combination of misuse of card data,
fraudulent applications for accounts or funds and account takeover.
Not all of the total is attributed to online activity, but industry
intelligence suggests that the Internet is an increasingly popular
channel for fraudsters to use both for compromising victims and
for carrying out fraud.
The harm done to the UK as a result of this
activity is significant. Direct losses tend to be transferred
quickly abroad using a variety of money laundering techniques,
where the assessment of a number of law enforcement agencies strongly
suggests that much of the cash finds its way into the hands of
organised criminals who use the money to fund further activities
including drug and people smuggling, prostitution and terrorism.
Consumers' understanding of the threat
The often complex nature of the attacks being
directed at consumers, coupled with a general unfamiliarity with
the equally complex nature of computing and the Internet, means
that many consumers are highly vulnerable. There is a misplaced
belief that personal computers are consumer products in the same
was as televisions or cameras. The truth is that although major
strides have been made in hiding the majority of a computer's
complexity from consumers, that complexity in fact still remains
and can be taken advantage of by knowledgeable attackers.
APACS research reveals that a small but significant
segment of the population remains vulnerable to social engineering
attacks like phishing. In August 2006 some 4 per cent of respondents
stated that they would respond to a phishing email, virtually
unchanged from a 2004 survey. Younger people appear disproportionately
vulnerable, with around 12 per cent of 18-24 year-olds stating
that they would respond in both surveys. Although the vast majority
of people recognise social engineering lures for what they are,
additional research undertaken by Indiana University[1]
indicates that, where phishing emails are highly personalised
with accurate information about the recipient (eg name, address
and other personal information) then response rates can climb
dramatically. The banking industry and law enforcement agencies
have seen that criminal gangs are putting more effort into obtaining
and using such details to improve the credibility of their lures.
One encouraging trend that we have noted is
that computer users are increasingly aware of, and are making
use of, security technologies such as regularly updated anti-virus
software, firewalls and operating system patches. Taken together,
such measures greatly help to protect a computer against infection.
However, the picture is not all good. We note that the UK remains
very high on an international league table[2]
for "zombie computers"computers that have been
infected with malware for purposes such as identity theft, phishing
and spamming. At one point last year it was estimated that nearly
a third of the world's "zombie" computers were located
in the UK. Often consumers express concerns about the additional
costs of securing their computers, particularly with regard to
anti-virus software although many free packages are available.
Using security measures is increasingly essential, and users should
be encouraged to think about them in much the same way that locks
and alarms are now considered to be perfectly reasonable measures
to have on cars and homes.
Malware writers are using ever more sophisticated
techniques, including so-called "rootkit" technologies.
Rootkits enable malware toamongst other thingshide
from computer users and from security software. The problem of
rootkits is rated as being so severe that a senior Microsoft security
manager has been quoted that often the only solution for dealing
with a computer infected with a rootkit may be to "nuke it
from orbit"[3]
by completely wiping the hard drive and reloading the operating
system and software from scratch. To expect the average computer
user to detect and respond properly to such devastating attacks
presents a considerable challenge.
TACKLING THE
PROBLEM
Information security support to private individuals
A number of UK banks offer their customers subsidised
or free security software. Banks also provide customers with advice
on how to protect themselves on their sites both directly and
via collective initiatives such as www.getsafeonline.org, www.identitytheft.org.uk
and www.banksafeonline.org.uk.
An important central consideration is that criminals
are targeting consumers because consumers are able to give away
their credentials to the criminal, either by stealth or by way
of a confidence trick. One way of mitigating this problem would
be to provide consumers with a security system in which they themselves
would not form the weakest link.
Many banks are seeking to do this via the introduction
of so-called "strong authentication" systems. These
can take many forms and include the use of a piece of equipment
(commonly known as a "token") to generate a unique passcode
that could only be used once, and which would change every time
it was required. In this way, a criminal would not be able to
re-use any captured information. In all cases banks complement
their specific customer authentication controls with additional
risk management and fraud detection controls within their on-line
banking service. These controls, which form a layered security
approach, are sometimes visible to the customer and sometimes
operate in the background, and are harder for criminals to overcome.
These measures are broadly consistent with the recommendations
made to US banks by the Federal Financial Institutions Examination
Council in 2005.
Increasing awareness and improving education
Based on the evidence gathered by APACS, whilst the
majority of computer users are generally aware of computer security
threats and do take sensible steps to reduce their exposure, a
minority continues to remain vulnerable. As stated previously,
this is despite many high-profile media stories and educational
efforts over the past few years, and indicates that future awareness-raising
efforts will need to focus particularly on that group of users
who remain most at risk.
These trends are despite numerous high profile
initiatives put in place over the past couple of years by the
banking industry, government and others to inform and educate
members of the public of the threats and to provide advice on
how to protect themselves. We believe that much more needs to
be done in order to bring about a significant shift in cultural
perceptions, and that this will require concerted and joined-up
action from government, in the form of public information efforts
and improvements to training and education in areas such as life
skills and computer skills.
A number of factors can prevent private individuals
from following appropriate security practices, including:
Lack of computer literacy skills.
Prevalence of inappropriate risk
judgements borne out of arrogance or naivety, eg "it can't
happen to me" or "I'm too clever to be taken in by such
things" or even "This email must be from my bank because
it's got their logo on it".
Complexity of applying technical
countermeasures, and of configuring them correctly.
Price of countermeasures.
Stakeholders' roles in ensuring effective protection
Effectively protecting individuals online is
a complex task that requires action from a wide range of stakeholders,
all of whom have roles to play:
Operating system vendors: The security
and stability of the computer's operating system is the foundation
upon which effective protection for all Internet based activity
must be built. Fortunately there has been significant improvement
in this area over recent years with the introduction of more secure
operating systems which are less open to abuse, and where necessary
easier to patch. It is a fundamental requirement that all operating
system vendors continue to maintain this effort, and make them
ever more stable requiring ever fewer critical patches to maintain
their security.
Internet browser vendors: The Internet
browser is the primary way in which consumers interact with internet
services, and therefore there is a need to ensure that browsers
are fundamentally more secure and less open to abuse. A key improvement
from a consumer perspective would be to examine how information
warnings and messages are presented to the users to ensure that
they are obvious and unambiguous. Far too many current messages
are susceptible to being ignored or misunderstood by users and
this allows them to be deceived into accepting malware that would
infect their PCs.
Computer security vendors: This includes
the wide range of anti-virus software, antispyware software and
firewall vendors. Here we feel that more can be done to focus
more on the specific threat of malware that has been specifically
written with the objective of ID theft. Often such malware is
targeted at relatively small numbers of victims, and the fear
is that many security vendors may not appropriately prioritise
these risks.
Internet Service Providers: The ISP
community provides users with the primary means to personal access
to the Internet. As such they are vital stakeholders to engage
with. There is a view that more can be accomplished by ISPs in
this area, which we will set out later in this submission.
Law Enforcement: The likelihood is
that the global nature of cyber-criminality will limit the ability
of Law Enforcement to secure prosecutions. It is with this in
mind that the concept of reducing harm to consumers is vital to
promote, and law enforcement under the banner of crime prevention
has a key role to play.
Government: The Government has a
wide range of responsibilities to protect consumers, most notably
through the creation of effective laws and regulation that will
help to prevent offences. As important, however, is providing
the means to ensure that individuals are less vulnerable to attack
through sound and effective education and awareness, recognising
that this will be a long term enduring problem. An additional
aspect of this is the dissemination of coherent and effective
advice and warnings to consumers of new vulnerabilities. Here
the Government could go much further than it has currently and
emulate the better practice found in other nations through the
establishment of a national Computer Emergency Response Team (CERT)
that could exercise this function.
E-commerce community: All those who
provide e-commerce services to users should work to educate their
user communities, and should take stronger action to protect the
information that they hold on their customers from the possibility
of being obtained and misused by criminals.
Banking industry: In addition to
their status as part of the wider e-commerce community, banks
are well placed to drive forward stronger authentication measures
that could provide wider benefits in the longer term. Moreover
there are effective benefits in sharing knowledge of the consequences
of the threat to end users, as it allows the industry to shape
its messages to consumers on what they can do to protect themselves.
Additionally it has allowed us to build a broader consensus on
why and how personal Internet users must be protected.
Individuals: All the security systems
and advice in the world are useless if individual users fail to
use them. So long as criminals continue to regard individuals
as a weak link in the security chain then they will continue to
be targeted. The great majority of individuals do behave sensibly
and securely, but the remainder should continue to be challenged
to alter their behaviour if only for their own good.
UK research into Personal Internet Security
The UK Payments Industry conducts, through APACS,
a number of regular surveys on how UK consumers use the Internet
for e-banking and making purchases. These surveys often include
more general questions in relation to personal Internet security;
some of the results of one of the most recent were set out earlier
in this response.
It is important to recognise that any research
into user attitudes to Internet security is challenging and ripe
with paradoxes that must be confronted in the design of any future
research. In simple terms this is characterised by users expressing
generalised and abstract fears from a perceived lack of security
on the Internet, whilst at the same time willingly using it regularly
to conduct their lives. We have as a consequence seen no definitive
evidence or conclusive research that security fears are driving
users away from Internet services.
Overall, however, UK research in this area could
be best characterised as patchy; there seems, for example, to
be no large-scale academic research experiments into the threat
of phishing and user reaction to it of the style we have seen
in US academic institutions. There is therefore much more that
could be achieved in trying to co-ordinate and promulgate the
results of research into Personal Internet Security across all
those conducting it.
GOVERNANCE AND
REGULATION
IT governance does not have a direct impact
on mitigating threats, and is not a direct influence on consumers
and personal internet safety. There are, however, implied benefits
in that organisations that adopt sound methods of IT governance
and which have adopted the best principles of information security
management are more likely to deliver systems that are robust
and resistant to attack. This will ensure that where these organisations
offer Internet based services, such as e-banking services offered
by APACS members to consumers, there is much greater confidence
that they will do so securely and provide the necessary protection
for the personal information they receive from the consumer.
Information security standardisation
The UK payments industry has been at the forefront
of applying the best principles of sound information security
management over a number of years, and has contributed with others
to ensuring that this best practice is enshrined in international
standards that others can follow; ISO 17799 The Code of Practice
for Information Security Management. There is increasing evidence
that certification against this code of practice is increasing
globally, and that it is highly relevant to enterprises offering
Internet-based services. This standard and other international
industry-specific standards, such as the Payment Card Industry
Data Security Standard (PCI DSS), are contributing to increasing
awareness of the need to implement security in order to mitigate
risk. Moreover it is argued that there are business benefits in
applying these standards. Demonstrating conformance to sound security
management practices and ensuring that personal information is
given adequate protection is now being seen as a method to promote
consumer confidence, and hence win repeat business.
A range of technical information security standards
being developed in the international standards bodies complements
these information security management standards. This is healthy
and desirable and over time these will contribute to building
security technologies suitable for the consumer market and thereby
enhance personal Internet security. These standards may take some
time to mature into viable secure and saleable products for the
consumer market because in many cases they are predicated on having
a secure PC host platform with no vulnerabilities. Our evidence
continues to show that this is not likely to be achieved soon.
One important technology that is often quoted in the context of
enhancing personal Internet security is the use of digital signature
technology. On a stable and secure host PC this would have benefit,
but if the digital signature was generated on a host PC for which
the provenance of the security is not known it is likely to have
questionable value. This is compounded in Europe by differing
national interpretations on digital signature legislation enacted
as a result of the EU e-signature directive. In some countries
any digital signature meeting certain criteria has a degree of
the weight of evidence in its favour that would make it difficult
to question its provenance, which is not the case in the UK. The
important consideration here is that it is often difficult to
generate common consistent legal interpretations of information
security technologies, despite common international understanding
and agreements.
Information security and regulation of Internet
services
From the perspective of the UK Payments Industry
on-line Internet based financial services are regulated under
the existing regulations that govern how any other financial service
is offered to UK consumers. There are distinct challenges when
considering the appropriate regulatory environment for other industries
as they start to offer Internet services. On the one hand the
relatively low cost to offer internet services with possible rich
rewards makes it an attractive business channel, whilst on the
other any severe regulatory burden could markedly constrain growth.
This is compounded by the lack, at least early on in the lifecycle
of a service, of any prevailing threat that would dictate regulation
or security. However, as we have seen in recent years the speed
with which criminals have been able to exploit a wide variety
of disparate channels for their profit is alarming.
An example of lighter touch regulation, which
at the time was appropriate and relevant but perhaps now needs
to be re-examined, is Section 17 of the Electronic Commerce (EC
Directive) Regulations 2002. This section, known as "Mere
Conduit", ensures that ISPs are not liable for any information
that passes over their networks. Whilst this is entirely reasonable
it has been used as defence by the ISPs for why they will not
monitor, and then take action against, their customers' host PCs
that have been compromised and are then used by criminals to send
spam, distribute malware or otherwise act maliciously.
There are other countries, such as Australia,
where there is much greater debate on this issue. In these cases
the argument is now being made in favour of ISPs being seen to
operate responsibly and to actively monitor their networks for
customers' PCs that have been compromised and then advising them
on remedial action. Given the fact that UK has been recorded[4]
as having one of the highest rates of compromised PCs in the world,
it is possible to argue that a similar policy in UK would substantially
improve personal Internet safety.
CRIME PREVENTION
The UK Government made a major step forward
a number of years ago in establishing the National High-Tech Crime
Unit (NHTCU) and in resourcing regional police forces' computer
crime units which provided the framework for national policing
of cyber crimes. APACS was a net contributor to the development
of the NHTCU and maintained a very close relationship with the
unit throughout its operational life. This provided an important
foundation for the joint activity in responding to, and combating
since September 2006 the rise in attacks against e-banking customers
in UK.
Domestic dimension
It was, therefore, with considerable interest that
we have tracked the merging of the NHTCU within SOCA as the e-Crime
directorate. It is commendable that in this process more resources
were to be given to the unit, and at the same time a realignment
of responsibilities saw the remit for child pornography passed
to the Child Exploitation and Online Protection (CEOP) Centre.
Both of these factors should enhance SOCA's ability to address
the broader issue of cyber crime of which prevention is a major
element of their strategy.
The dilemma is that in subsuming NHTCU within
SOCA their primary remits as a national centre of excellence upon
which regional forces could draw as required, and as the guardians
of the discipline of investigating cyber crime can no longer be
applied. As such there is a gulf in this area within the UK that
is reducing the effectiveness of cyber crime prevention. The recent
proposals by Commander Sue Wilkinson of the Metropolitan Police,
who is the ACPO lead for this topic, for a national co-ordinating
body on cyber crimes is one that APACS warmly supports.
International dimension
These attacks against e-banking, and other cyber
attacks such as the denial of service attacks against on-line
gambling sites, are a global problem from criminals who themselves
operate globally. NHTCU, and now SOCA, led the initiative that
has seen marked progress in establishing the necessary framework
of international co-operation amongst law enforcement agencies
needed to combat these threats. We have fully supported this effort
and where necessary complemented it by establishing our own peer
relationships with similar communities of interests affected by
e-banking attacks in other countries, most notably Australia,
Brazil, Germany and the USA. The UK continues to be one of the
most effective in establishing this form of international co-operation.
Computer crime criminal law
One of our major points to the All Party Internet
Group on their review of the Computer Misuse Act was the proposal
to make the penalties greater and to include DoS attacks explicitly
within the scope of the act. The recent proposed improvements
to the Computer Misuse Act included in the Police and Justice
Act, are very positive indications of the Government's willingness
to continue to improve existing legislation. A further example
is the Fraud Bill, which will provide powers to combat deception
as a means of executing fraud; this will therefore make phishing
illegal and is welcomed by the industry.
As important as these moves are, there is a
need for legislation that is clear and that will provide a measure
of stability as technology changes. In this light the industry
was concerned about some of the proposed changes to the CMA under
the Police and Justice Act that criminalise security tools, although
reassurances have been given that the intent is not to prevent
enterprises using these tools to ensure the security of their
own systems. The important consideration, however, is that any
legislation designed to combat cybercrime needs to be carefully
framed if it is not to have unwarranted consequences for legitimate
activity that promotes security.
