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 October 2018 and 31 December 2018 (referred to as ‘data breaches’).

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

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.

Source of the breaches — All sectors

This chart breaks down the sources of data breaches as identified by notifying entities in all sectors in the quarter.

Chart 1.4 — Source of data breaches by percentage — All sectors

Pie chart shows source of data breaches. There are three - from most to least notifications: Malicious or criminal attack accounted for 64%, Human error for 33% and System fault for 3%. Link to long text description follows chart.

Malicious or criminal attacks accounted for 168 data breaches this quarter, while human error accounted for 85 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 cyber incidents in this quarter appear to have exploited vulnerabilities involving a human factor, such as clicking on a phishing email or disclosing passwords.

Human error breaches — All sectors

This chart breaks down the kinds of breaches identified as ‘human error’ in the quarter.

Chart 1.5 — Human error breakdown — All sectors

Bar chart breaks down the human error data breaches. There are 10 types in the chart. The top 2 are: Personal information sent to the wrong recipient (email) with 23 notifications; and Unauthorised disclosure (unintended release or publication) with 15 notifications. Link to long text description follows chart.

The second largest source of data breaches was human error, with examples including sending personal information to the wrong recipient via email (27 per cent) or mail (12 per cent) as well as unintended release or publication of personal information (18 per cent).

Certain kinds of 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 17,746 affected individuals per breach). Failure to securely dispose of records of personal information impacted an average of 300 affected individuals per breach.

Link to long text description follows chart.

Malicious or criminal attacks were the largest source of data breaches this quarter, accounting for 64 per cent of all data breaches. Of these 168 data breaches, 68 per cent involved cyber incidents such as phishing, malware or ransomware, brute-force attacks, compromised or stolen credentials, and social engineering or impersonation.

Many cyber incidents in this quarter appear to have exploited vulnerabilities involving a human factor, such as clicking on an attachment to a phishing email.

Theft of paperwork or data storage devices was also a significant source of malicious or criminal attacks (15 per cent). Other sources included actions taken by a rogue employee or insider threat (12 per cent), as well as social engineering or impersonation (5 per cent).

Comparison of top five sectors that reported breaches in the quarter

This section compares notifications made under the Notifiable Data Breaches scheme by the five sectors that made the most notifications in the quarter (top five sectors).

Top five sectors

Top five sectorsNDBs received
Health service providers [1] 54
Finance (incl. superannuation) [2] 40
Legal, accounting and management services 23
