Almost 2.6 billion records were stolen, lost or exposed worldwide in 2017, an 88 percent increase over the previous year.
Although data breach incidents decreased by 11 percent, 2017 was the first year publicly disclosed breaches surpassed more than two billion compromised data records since
Gemalto began its Breach Level Index in 2013.
The index shows that over the past five years, nearly 10 billion records have been lost, stolen or exposed, with an average of five million records compromised every day. Of the 1,765 data breach incidents in 2017, identity theft represents the leading type of breach, accounting for 69 percent.
Malicious outsiders remain the number one cybersecurity threat with 72 percent of all breach incidents last year. Companies in the healthcare, financial services and retail sectors were the primary targets for breaches last year. However, government and educational institutions were not immune to cyber risks in 2017, making up 22 percent of all breaches.
Accidental loss, including improper disposal of records, misconfigured databases and other unintended security issues, caused 1.9 billion records to be exposed. This represents a huge 580 percent increase in the number of compromised records from 2016.
