About this report

This report captures notifications received by the Office of the Australian Information Commissioner (OAIC) under the Notifiable Data Breaches (NDB) scheme between 1 January 2019 and 31 March 2019 (referred to as ‘data breaches’).

The OAIC publishes statistical information about notifications received under the NDB scheme to assist entities and the public to understand the operation of the NDB scheme and the causes of data breaches.

Where data breaches affect multiple entities, the OAIC may receive multiple notifications relating to the same data breach. Notifications to the OAIC relating to the same data breach incident are counted as a single notification in this report.

The source of any given data breach is based on information provided by the reporting entity. Where more than one source has been identified or is possible, the dominant or most likely source has been selected for statistical purposes. Source of data breach categories are defined in the glossary at the end of this report.

Please note, from July 2019 the OAIC will report every six months on notifications received under the NDB scheme.

Note: Where bands are not shown (for example, 500 001 – 1 000 000) there were nil reports in the period. ‘Unknown’ includes notifications by entities whose investigations were ongoing at the time of this report. For the band 10,000,001 or more, this figure reflects the number of individuals worldwide whose personal information was compromised in this data breach, not only individuals in Australia, as estimated by the notifying entity.

Chart 1.2: Long text description

The majority of data breaches in the period involved the personal information of 100 individuals or fewer (68 per cent of data breaches).

Data breaches impacting between one and 10 individuals comprised 50 per cent of the notifications.

Source of data breaches by percentage — All sectors

Chart 1.4: Long text description

Malicious or criminal attacks accounted for 131 data breaches this quarter, while human error accounted for 75 data breaches. System faults accounted for nine data breaches. Malicious or criminal attacks differ from human error breaches in that they are deliberately crafted to exploit known vulnerabilities for financial or other gain. Many incidents in this quarter appear to have exploited vulnerabilities involving a human factor, such as clicking on a phishing email or by using social engineering or impersonation to obtain access to personal information fraudulently.

Human error data breaches — All sectors

This chart shows the types of data breaches identified as ‘human error’ during the quarter.

Chart 1.5 — Human error breakdown — All sectors

Human error data breaches — All sectors

Chart 1.5: Long text description

The second largest source of data breaches was human error, such as sending personal information to the wrong recipient via email (31 per cent), loss of paperwork or storage device (16 per cent) as well as the unintended release or publication of personal information (28 per cent).

Certain kinds of data breaches can affect larger numbers of people. For example, in this quarter data breaches involving human error resulting in the unintended release or publication of personal information impacted the largest numbers of people (an average of 36,993 affected individuals per data breach). This is consistent with the previous quarterly trend. Failure to use BCC when sending emails impacted an average of 432 individuals per data breach.

The NDB scheme applies to agencies and organisations that the Privacy Act 1988 (Cth) (Privacy Act) requires to take reasonable steps to secure personal information. This includes Australian Government agencies, businesses and not-for-profit organisations with an annual turnover of $3 million or more, credit reporting bodies, health service providers, and tax file number (TFN) recipients, among others.

From January to March 2019, the top sector to report data breaches under the NDB scheme was the private health service provider sector (health sector) (27 per cent). The second largest source of NDBs was the finance sector (13 per cent). This was followed by the legal, accounting and management services sector (11 per cent), the private education sector (education) (9 per cent), and the retail sector (5 per cent).

Notifications made under the My Health Records Act 2012 are not included in this report, as they are subject to specific notification requirements set out in that Act.
