Dear Stakeholders,

We’re hearing reports that the 'Petya' ransomware virus is spreading around the world.

Take steps to ensure you’re protected, or can recover if you’re affected.

Check with your IT support provider that the usual security precautions are in place:

  • Make sure your security software patches are up to date. The systems affected are described in this notice.
  • Make sure that you are running proper anti-virus software.
  • Back up your data and store it in a location that is not connected to your main computer system. This is your best protection from ransomware because you can’t be held to ransom if the data is available from another place. Are you assured that your backups are working? A regular restore from backup must be done.

You should not have any computers running Windows XP. If you do, you should immediately apply the Microsoft patch, then plan to update to a newer operating system as soon as possible.

Remind staff and colleagues about the risk of clicking links in emails or opening attachments (especially when they’re from an unknown email address).

To reduce the risk:

  • First hover on the link with your mouse pointer, and look at where the link is taking you.
  • Take a second to think. Any link or attachment that is not from within your practice or immediate network, or a recognised friend, should not to be clicked. When in doubt, either call or email (in a separate email) your friend or the organisation asking them to confirm that the email is legitimate.
  • Only click if you’re sure it’s safe.

More information about ransomware in the health sector is available from the Australian Digital Health Agency on their Cyber Security page. You can also read today's security alert.

The Australian Cyber Security Centre can support you if you need information or advice: 1300Cyber1 or acsc.gov.au.

And finally, the RACGP’s Computer and information security standards are freely available. They are a collection of best practice advice for protecting your systems.

Sincerely,
