From press release:
Symantec Corp. today released its Report on the Underground Economy. The report details an online underground economy that has matured into an efficient, global marketplace in which stolen goods and fraud-related services are regularly bought and sold, and where the estimated value of goods offered by individual traders is measured in millions of dollars. The report is derived from data gathered by Symantec’s Security Technology and Response (STAR) organization, from underground economy servers between July 1, 2007 and June 30, 2008.
The potential value of total advertised goods observed by Symantec was more than $276 million for the reporting period. This value was determined using the advertised prices of the goods and services and measured how much advertisers would make if they liquidated their inventory.
Credit card information is the most advertised category of goods and services on the underground economy, accounting for 31 percent of the total. While stolen credit card numbers sell for as little as $0.10 to $25 per card, the average advertised stolen credit card limit observed by Symantec was more than $4,000. Symantec has calculated that the potential worth of all credit cards advertised during the reporting period was $5.3 billion.
