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 July 2018 and 30 September 2018 (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.
Notifications received from all industry sectors

Chart 1.2 — Number of individuals affected by breaches in the quarter — All sectors
Note: Where bands are not shown (for example, 25,001 to 50,000), there were nil reports in the period. ‘Unknown’ includes notifications by entities whose investigations were ongoing at the time of this report.
Most data breaches in the period involved the personal information of 100 individuals or fewer (63 per cent of data breaches).
Data breaches impacting between 1 and 10 individuals comprised 41 per cent of the notifications.
Kinds of personal information involved in breaches — All sectors
Chart 1.3 — Kinds of personal information involved in breaches by number of notifications — All sectors
Note: Data breaches may involve one or more kinds of personal information.
Kinds of personal information | % of total NDBs received |
---|---|
Contact information | 85% |
Financial details | 45% |
Identity information | 35% |
TFN | 22% |
Health information | 22% |
Other sensitive information | 7% |
The majority of data breaches involved ‘contact information’, such as an individual’s home address, phone number or email address. This is distinct from ‘identity information’, which refers to information that is used to confirm an individual’s identity, such as passport number, driver’s licence number or other government identifiers.
Entities also notified data breaches that involved financial details, such as bank account or credit card numbers, individuals’ tax file numbers (TFNs), as well as health information. ‘Other sensitive information’ refers to categories of sensitive information as set out in section 6(1) of the Privacy Act, other than health information as defined in section 6FA.
Source of the breaches — All sectors
This chart breaks down the sources of data breaches as identified by notifying entities in all industry sectors in the quarter.
Chart 1.4 — Source of data breaches by percentage — All sectors
Malicious or criminal attacks accounted for 57 per cent of data breaches reported this quarter (139 notifications).
Malicious or criminal attacks differ from human error data breaches in that they are deliberately crafted to exploit known vulnerabilities for financial or other gain. Attacks included cyber incidents such as phishing, malware, ransomware, brute-force attack and hacking by other means, as well as social engineering or impersonation and actions taken by a rogue employee or insider threat. Theft of paperwork or storage devices was also reported as a source of malicious or criminal attacks. Many cyber incidents this quarter appear to have exploited vulnerabilities involving a human factor (such as clicking on a phishing email or disclosing passwords).
Human error remained a significant source of data breaches, accounting for 37 per cent of all incidents reported (92 notifications).
System faults accounted for 6 per cent of data breaches (14 notifications).
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
The second largest source of data breaches was human error. Sending personal information to the wrong recipient via email accounted for 12 per cent of all data breaches during the quarter. This was followed by the unintended release or publication of personal information (6 per cent), loss of paperwork/data storage device (5 per cent), and sending personal information to the wrong recipient via mail (5 per cent). This quarter also included incidents where personal information was provided to the wrong recipient via channels other than email, fax or mail, for example, delivery by hand or uploading to web portal.
However, certain kinds of data breaches can affect larger numbers of people. For example, in this quarter data breaches involving unauthorised disclosure as a result of a failure to redact personal information impacted the largest numbers of individuals (an average of 633 affected individuals per breach). Failures to use the ‘blind carbon copy’ (BCC) function when sending group emails impacted an average of 494 individuals per data breach. In contrast, human errors involving sending personal information to the wrong recipient generally impacted smaller groups of individuals.
Kinds of personal information | No. of NDBs received | Average no. of affected individuals |
---|---|---|
Unauthorised disclosure (failure to redact) | 4 | 633 |
Failure to use BCC when sending email | 6 | 494 |
Unauthorised disclosure (unintended release or publication) | 14 | 94 |
Insecure disposal | 1 | 79 |
PI sent to wrong recipient (email) | 29 | 70 |
PI sent to wrong recipient (mail) | 13 | 35 |
Unauthorised disclosure (verbal) | 6 | 11 |
Loss of paperwork/data storage device | 13 | 8 |
PI sent to wrong recipient (fax) | 2 | 5 |
PI sent to wrong recipient (other) | 4 | 4 |
Malicious or criminal attack breaches — All sectors
This chart breaks down the kinds of breaches identified as ‘malicious or criminal attack’ in the quarter.
Chart 1.6 — Malicious or criminal attacks breakdown — All sectors
Malicious or criminal attacks were the largest source of data breaches this quarter, accounting for 57 per cent of all notifications.
Of the 139 data breaches resulting from a malicious or criminal attack, 69 per cent involved cyber incidents. Many cyber incidents in this quarter involved the exploitation of vulnerabilities involving a human factor (such as clicking on an attachment to a phishing email), as well as incidents involving malware, ransomware, and hacking by other means.
Theft of paperwork or storage devices was the second most reported source of malicious or criminal attacks (12 per cent).
Other sources included actions taken by a rogue employee or insider threat (10 per cent) and social engineering or impersonation (9 per cent).

System fault breaches — All sectors
This chart breaks down the kinds of breaches identified as ‘system fault’ in the quarter.
Chart 1.8 — System fault breakdown — All sectors
System faults accounted for 6 per cent of data breaches this quarter.
Across all sectors, 9 data breaches related to the unintended release or publication of personal information as a result of a system fault. This includes the disclosure of personal information on a website due to a bug in the web code, or a machine fault that results in a document containing personal information being sent to the wrong person.
Additionally, 5 data breaches related to unintended access to personal information as a result of a system fault, such as a coding error which allows an individual to access another individual’s online account.
Comparison of top 5 industry sectors that reported breaches in the quarter
This section compares notifications made under the NDB scheme by the five industry sectors that made the most notifications in the quarter (top 5 industry sectors).
