Malicious outsiders accounted for 58% of data breaches in 2015

Last year 1,673 data breaches led to 707 million data records being compromised worldwide.

Gemalto has released findings of its 2015 Breach Level Index (BLI), a global database that tracks data breaches on a global scale and measures their severity based on multiple dimensions.

The BLI found that more than 3.6 billion data records had been exposed since 2013. In 2015, malicious outsiders accounted for 964 or 58 percent of breaches and 38 percent of compromised records. Identity theft accounted for 53 percent of data breaches and 40 percent of all compromised records.

Accidental loss or exposure of data records accounted for 36 percent of all records. State-sponsored attacks accounted for two percent, but the number of records compromised as a result of those attacks amounted to 15 percent of all exposed records. Malicious insiders accounted for 14 percent of all data breaches and only seven percent of compromised records.

The most (77 percent of total) data breaches occurred in North America, with 59 percent of all compromised records occurring in the US. Europe accounted for 12 percent of overall breach incidents, the Asia Pacific region followed at eight percent.

“As companies and devices collect ever-increasing amounts of customer information and as consumers' online digital activities become more diverse and prolific, more data about what they do, who they are and what they like is at risk to be stolen from the companies that store their data. If consumers' entire personal data and identities are being co-opted again and again by cyber thieves, trust will increasingly become the centerpiece in the calculus of which companies they do business with,” says Jason Hart, VP and CTO for data protection at Gemalto.
