The graph below was created using Google’s graphing tools.
The vertical bar graph shows the relative value of categories of stolen information (and some services, e.g. cash-out services) that criminals sell in the underground economy.
The data in the graph is from a study done by First Data titled “Fraud Trends in 2010: Top Threats from a Growing Underground Economy”. The data from the First Data study is based on a 2008 study done by Symantec. The First Data study can be read by clicking here (PDF file).
Symantec analyzed underground economy websites where illegally-obtained information was posted for sale. The percentages on the graph are of total sales value on the underground economy websites that Symantec estimated each of the 10 illegally-obtained listed information (and service) categories accounted for. Symantec found that for the period they looked at the advertized offerings on the websites the total sales prices for all offerings was around $276 million. And, after further analysis, Symantec found that credit card information sales offerings represented 18% (the most of the categories) of the $276 million, and the other top 9 sales offerings are as shone on the graph.
