Survey: Data breaches from malicious attacks doubled last year
The cost per compromised record involving a criminal act averaged $215, about 40 percent higher than breaches from negligence and 30 percent higher than those from glitches, the survey found.
For the first time, companies reported in the survey that data-stealing malware caused their breaches.
The average organizational cost of a data breach increased nearly 2 percent to $6.75 million in 2009, while the average cost per compromised record per breach rose only $2 to $204. The most expensive breach in the survey was nearly $31 million and the least expensive was $750,000.
Meanwhile, 42 percent of all cases reported in the survey involved mistakes made at third parties, such as outsourcers, and 36 percent of the cases involved lost or stolen laptops or other mobile devices.
For the study, 45 U.S. companies from 15 different industries were surveyed. The figures include business costs including expenditures for detection, notification, and response, as well as the economic impact of lost or diminished customer trust and confidence as measured by customer turnover rates.
