The existence of cybercrime can be traced back to many years. Over these years, the threat has evolved to a severe problem for individuals, organizations, and hence, the society at large. Global adoption of the Internet and the proliferation of payment-linked online services, which attract profit-seeking criminals are the primary drivers for such attacks. For instance, according to the National Crime Agency of the United Kingdom, cybercrime has surpassed all forms of traditional crimes. The natural sources to quantify crimes are police-recorded statistics. In the context of cybercrime, however, some limitations and caveats put police-recorded statistics to doubt. A lack of consensus of what constitutes a cybercrime is one among such. As a missing authoritative definition, some offences may be classified as cyber when in fact they are not, while others may be concealed within other criminal statistics.
