With improved technology and world-wide Internet access, spam, or unsolicited bulk email, is now a widely used medium for committing traditional white collar crimes including financial institution fraud, credit card fraud, and identity theft, among others. It is usually considered unsolicited because the recipients have not opted to receive the email. Generally, this bulk email refers to multiple identical messages sent simultaneously. Those sending this spam are violating the Controlling the Assault of Non-Solicited Pornography and Marketing (CAN SPAM) Act, Title 18, U.S.C., Section 1037.

Spam can also act as the vehicle for accessing computers and servers without authorization and transmitting viruses and Botnets. The subjects masterminding this Spam often provide hosting services and sell open proxy information, credit card information, and email lists illegally.
