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 represented the leading type of data breach, accounting for 69% of all data breaches. Malicious outsiders remained the number one cybersecurity threat last year at 72% of all breach incidents. 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% of all breaches.
The Breach Level Index* serves as a global database that tracks and analyses data breaches, the type of data compromised and how it was accessed, lost or stolen. Based on data breach reports collected in the Breach Level Index, the major 2017 highlights include:
"The manipulation of data or data integrity attacks pose an arguably more unknown threat for organisations to combat than simple data theft, as it can allow hackers to alter anything from sales numbers to intellectual property. By nature, data integrity breaches are often difficult to identify and in many cases, where this type of attack has occurred, we have yet to see the real impact,” said Jason Hart, Vice President and Chief Technology Officer for Data Protection at Gemalto. In the event that the confidentiality, or privacy, of the data is breached, an organisation must have controls, such as encryption, key management and user access management, in place to ensure that integrity of the data isn’t tampered with and it can still be trusted. Regardless of any concerns around manipulation, these controls would protect the data in situ and render it useless the moment it's stolen.”
Data Breaches by Type
Identity theft was the leading type of data breach, accounting for 69% of all incidents constituting 26% of breached data in 2017. The second most prevalent type of breach was access to financial data (16%). The number of lost, stolen or compromised records increased the most for nuisance type of data breaches (560%) which constituted 61% of all compromised data. Account access and existential type breaches decreased both in incidents and records from 2016.
Data Breaches by Industry
In 2017, the industries that experienced the largest number of data breach incidents were healthcare (27%), financial services (12%), education (11%) and government (11%). In terms of the amount of records lost, stolen or compromised, the most targeted sectors were government (18%), financial services (9.1%) and technology (16%).
Data Breaches by Source
Malicious outsiders were the leading source of data breaches, accounting for 72% of breaches, however making up only 23% of all compromised data. While accidental loss was the cause of 18% of data breaches, it accounted for 76% of all compromised records, an increase of 580% from 2016. Malicious insider breaches were 9% of the total number of incidents, however this breach source experienced a dramatic increase (117%) in the number of compromised or stolen records from 2016.
