I have found cyber crime statistics in filed of Hi-tech . The more cyber crimes increase, the more need for investigation increases as well. The statistic are empirical study on the base of 1500 survey conducted online.
Cyber Crime Statistics from the 2008 Internet Crime Report
In 2008, the Internet Crime Complaint Center received and processed over 200,000 complaints.
More than 86,000 of these complaints were processed and referred to various local, state, and federal law enforcement agencies.
Most of these were consumers and persons filing as private persons.
Total alleged dollar losses were more than $194 million.
Email and websites were the two primary mechanisms for fraud.
Although the total number of complaints decreased by approximately 7,000 complaints from 2005, the total dollar losses increased by $15 million.
The top frauds reported were auction fraud, non-delivery of items, check fraud, and credit card fraud.
Top contact mechanisms for perpetrators to victims were email (74%), web page (36%), and phone (18%) (there was some overlap).
Cyber Crime Statistics from the 12th Annual Computer Crime and Security Survey*
Between 2007 and 2008there was a net increase in IT budget spent on security.
Significantly, however, the percentage of IT budget spent on security awareness training was very low, with 71% of respondents saying less than 5% of the security budget was spent on awareness training, 22% saying less than 1% was spent on such training.
71% of respondents said their company has no external insurance to cover computer security incident losses.
90% of respondents said their company experienced a computer security incident in the past 12 months.
64% of losses were due to the actions of insiders at the company.
The top 3 types of attack, ranked by dollar losses, were:
financial fraud ($21.1 million)
viruses/worms/trojans ($8.4 million)
system penetration by outsiders ($6.8 million)
Cyber Crime Statistics from the Online Victimization of Youth, Five Years Later study*
Increasing numbers of children are being exposed to unwanted sexual materials online.
Reports of online sexual solicitations of youth decreased while reports of aggressive sexual solicitation of youth did not (perhaps indicating that some prevention and education measures may be working, while the most serious offenders may not be deterred).
Online child solicitation offenses are rarely reported to any authority.
Incidents of online harassment and bullying increased.
