Chapter 3 : 3. The challenges of fighting cybercrime
3.1 Opportunities
Law-enforcement agencies can now use the increasing power of computer systems and complex forensic software to
speed up investigations and automate search procedures. It can prove difficult to automate investigation processes.
While a keyword-based search for illegal content can be carried out easily, the identification of illegal pictures is
more problematic. Hash-value based approaches are only successful if pictures have been rated previously, the hash
value is stored in a database and the picture that was analysed has not been modified.
Forensic software is able to search automatically for child-pornography images by comparing the files on the hard
disk of suspects with information about known images. For example, in late 2007, authorities found a number of
pictures of the sexual abuse of children. In order to prevent identification the offender had digitally modified the
part of the pictures showing his face before publishing the pictures over the Internet. Computer forensic experts
were able to unpick the modifications and reconstruct the suspect’s face. Although the successful investigation
clearly demonstrates the potential of computer forensics, this case is no proof of a breakthrough in childpornography
investigation. If the offender had simply covered his face with a white spot, identification would have
been impossible.
3.2 General challenges
3.2.1 Reliance on ICTs
Many everyday communications depend on ICTs and Internet-based services, including VoIP calls or e- mail
communications.ICTs are now responsible for the control and management functions in buildings, cars and aviation
services. The supply of energy, water and communication services depend on ICTs. The further integration of ICTs
into everyday life is likely to continue. Growing reliance on ICTs makes systems and services more vulnerable to
attacks against critical infrastructures. Even short interruptions to services could cause huge financial damages to
ICTs is a major risk for military communications.
Existing technical infrastructure has a number of weaknesses, such as the monoculture or homogeneity of operating
systems. Many private users and SMEs use Microsoft’s operating system, so offenders can design effective attacks
by concentrating on this single target.
The dependence of society on ICTs is not limited to the western countries. Developing countries also face challenges
in preventing attacks against their infrastructure and users. The development of cheaper infrastructure
technologies such as WiMAX has enabled developing countries to offer Internet services to more people. Developing
countries can avoid the mistakes of some western countries, which have concentrated mainly on maximizing
accessibility, without investing significantly in protection. US experts have explained that successful attacks against
the official website of governmental organizations in Estonia could only take place due to inadequate protection
measures. Developing countries have a unique opportunity to integrate security measures early on. This may
require greater upfront investments, but the integration of security measures at a later point may prove more
expensive in the long run.
Strategies must be formulated to prevent such attacks and develop countermeasures, including the development
and promotion of technical means of protection, as well as adequate and sufficient laws enabling law-enforcement
agencies to fight cybercrime effectively.
3.2.2 Number of users
The popularity of the Internet and its services is growing fast, with over 2 billion Internet users worldwide by 2010.
Computer companies and ISPs are focusing on developing countries with the greatest potential for further growth.
In 2005, the number of Internet users in developing countries surpassed the number in industrial nations, while the
development of cheap hardware and wireless access will enable even more people to access the Internet.
difficult to estimate how many people use the Internet for illegal activities. Even if only 0.1 per cent of users
committed crimes, the total number of offenders would be more than one million. Although Internet usage rates are
lower in developing countries, promoting cybersecurity is not easier, as offenders can commit offences from around
the world.
The increasing number of Internet users causes difficulties for the law-enforcement agencies because it is relatively

difficult to automate investigation processes. While a keyword-based search for illegal content can be carried out
rather easily, the identification of illegal pictures is more problematic. Hash-value based approaches are for
example only successful if the pictures were rated previously, the hash value was stored in a data base, and the
picture that was analysed has not been modified.
3.3 Legal challenges
3.3.1 Challenges in drafting national criminal laws
Proper legislation is the foundation for the investigation and prosecution of cybercrime. However, law- makers must
continuously respond to Internet developments and monitor the effectiveness of existing provisions, especially given
the speed of developments in network technology.

Historically, the introduction of computer-related services or Internet-related technologies has given rise to new
forms of crime, soon after the technology was introduced. One example is the development of computer networks in
the 1970s – the first unauthorized access to computer networks occurred shortly afterwards. Similarly, the first
were used to copy software products.
It takes time to update national criminal law to prosecute new forms of online cybercrime. Indeed, some countries
have not yet finished with this adjustment process. Offences that have been criminalized under national criminal law
need to be reviewed and updated. For example, digital information must have equivalent status as traditional
signatures and printouts.
Without the integration of cybercrime-related offences, violations cannot be prosecuted.
The main challenge for national criminal legal systems is the delay between the recognition of potential abuses of
new technologies and necessary amendments to the national criminal law. This challenge remains as relevant and
topical as ever as the speed of network innovation accelerates. Many countries are working hard to catch up with
legislative adjustments. In general, the adjustment process has three steps: adjustment to national law,
identification of gaps in the penal code, and drafting of new legislation.
Adjustments to national law must start with the recognition of an abuse of new technology
Specific departments are needed within national law-enforcement agencies, which are qualified to investigate
potential cybercrimes. The development of computer emergency response teams (CERTs), computer incident
response teams (CIRTs), computer security incident response teams (CSIRTs) and other research facilities have
improved the situation.
