Compromises in 2009
Total compromises in 2009 were in excess of 251.8 million. While the number of compromised accounts was the largest in recent years the number of incidents were just 61, implying fewer, but larger breaches. The largest financial breach was Heartland Payment Systems on 1/20/2009 where 130 million charge cards were compromised. This single breach accounted for over 95% of all 2009 financial breaches reported.
The largest non-financial breach was on 10/2/2009 when a failing hard drive was not properly destroyed. It may have compromised Social Security numbers, and other information, on 76 million veterans as far back as 1972. This single breach was more than half of the total 2009 non-financial compromises.
There were four times as many non-financial (those exposing social security numbers, names, email addresses, telephone numbers, medical information or other personal data) breaches than financial breaches (those exposing charge card or bank account information).
