In 2008, the theft of personal data totaled 285,000 records among American companies, more than those observed between 2004 and 2007 combined, equivalent to nine pieces of information per second, says Verizon.
According to the 2009 Data Breach Investigations Report (DBIR) analysis, based on 90 typical security breaches, organized crime was behind 90 percent of the actions recorded during the past year.
The Verizon study only took into account attacks that resulted in the theft of data that was later used in a crime, such as counterfeiting credit cards or usurping identity to purchase items, the Associated Press reports.
Invasion was the main method used to obtain data for the fifth consecutive year, a procedure adopted in 94 percent of registered cases.
Those responsible for the study also report that 90 percent of vulnerabilities could have been prevented with elementary security measures.
