Breakdown of Goods Available for Sale on Underground Economy Servers

During the first six months of 2007, 8,011 distinct credit cards were observed being advertised for exchange on underground economy servers. This is only a small proportion of the credit cards sold, however. Typically, users selling credit card information advertise bulk rates and merely give examples of credit card information to attract buyers. Common bulk amounts and rates seen during the first six months of 2007 were: 10 credit card numbers for $20 USD; 50 credit card numbers for $70 USD; and 100 credit card numbers for $100 USD.
