Cyber crimes can be divided into 11 groups and each of them is different. Those are unauthorized access to computer systems or networks (hacking), theft of information contained in the electronic form, email bombing, data diddling, salami attacks, denial of service attack, virus and worm attacks, logic bombs, Trojan attacks, internet time thefts, and web jacking. International estimates announce that cybercrime costs approximately $50 billion annually. Cybercrime costs the United States more than $5 billion per year.

According to Michigan State University Library, in England, cybercrime is estimated to cost approximately 250 million pounds or $417.7 million annually. Looking at these figures it can be said that cybercrime is a concept that should be reviewed carefully taking different aspects of it into consideration like the causes, victims and statutory provisions. Still, there are so many countries that have not updated their laws against cybercrime. The lack of strong regulations makes it nearly impossible to arrest cyber criminals in those countries.
