Q: What precautionary steps can I take?
A: Based on the types of information that may have been accessed, we recommend you take the following steps (depending on the types of information you have previously provided to D1):
Where a third party may have access to your contact information, it is important to:
- be aware of email, telephone and text-based scams. Do not share your personal
information with anyone unless you are confident about who you are sharing it with;
- when on a webpage asking for your login credentials, take note of the web address or URL ('Uniform Resource Locator'). The URL is located in the address bar of your web browser and typically starts with ‘https://’;
- if you are suspicious of the URL, do not provide your login details. Contact the entity through the usual channels to ensure you are logging into the correct web page.
- Please note that Dental One will never contact you to ask for your username or
- enable multi-factor authentication for your online accounts where possible, including your email, banking, and social media accounts;
- ensure you have up-to-date anti-virus software installed on any device you use to access your online accounts; and follow the Australian Competition and Consumer Commission's Scamwatch guidance for protecting yourself from scams here: https://www.scamwatch.gov.au/get-help/protect-yourself-from-scams/.

Dental health information related to you have been identified in the affected dataset. For context, cyber-criminals typically seek to misuse information that can be easily used for financial gain (such as credit cards and identity documents for identity theft). For this reason, health information by itself is generally not useful to a cyber-criminal.
However we know that it will be concerning to learn that your health information may have been accessed in this manner.
Should you experience any anxiety or distress in relation to this, please seek medical advice from your regular treating physician or GP.

Q. Why has it taken time to notify individuals?
A: It was necessary for us to carefully analyse the affected dataset to understand exactly what information was affected and who it belonged to so that our notification to affected individuals was accurate and did not cause any undue alarm or distress. This type of detailed analysis takes time, and we have been mindful to ensure our process and notification has been as thorough as possible.
