BREACH LEVEL INDEX
DATA BREACHES BY TYPE
During the first half of 2015, attackers used a variety of techniques against organizations to acquire personal identities, financial data, or access to account information.
The leading type of data breach in the first half of 2015 was identity theft as the cause of 472 data breaches, accounting for more than half (53.2%) of first half
2015 attacks and nearly three- quarters (74.9%) of compromised data records. Five of the top 10 breaches in the first half 2015, including the top three, were identity theft breaches.
The next most common type
of data breach was financial access to data. Responsible for 197 breaches in the first half, financial access accounts for 22.2% of the total but only about 1% of compromised data records. Other data breach types include existential data (96 breaches, 10.8%), account access (93 breaches, 10.5%) and nuisance (30 breaches, 3.4%).
The frequency of these attack types in the first half of the year is largely in line with all of 2014 with some minor fluctuations in the percentages.

Compromised
Data Records Concerning compromised data records, identity theft also was the leading cause of data records exposure in the first half of 2015 with 185.7 million records, or about three quarters of all records (74.9%), exposed in
the first half. Next was account access (34.3 million for 13.9%), followed by nuisance (15 million for 6.1%), existential data
(8.8 million for 3.6%) and financial access (2 million for 0.8%).
Perhaps the most notable changes compared with the second half of 2014 were that the share of data records attributed to identity theft that were stolen rose from 30.2%, and stolen data records attributed to account access dropped from 50.2%.
