Prime Minister Scott Morrison has spoken about a major cyber attack.
The cyber attacks were widespread, covering "all levels of government" as well as essential service providers and businesses, according to BBC news.
Australia is leading by example and helping companies and local governments to understand the threats and what to do to mitigate them.
The Australian Cyber Security Center has identified the state-actor using multiple spearphishing techniques through emails with malicious links or files as well as credential harvesting websites.
There have also been reports of links prompting users to grant Office 365 OAuth tokens to the attacker.
There is no doubt that malicious cyber activity is increasing in frequency, style, sophistication, and also in its impact. This activity severely harms Australia's national security and economic interests.
It's vital that all Australian organizations are aware of these threats and take steps to protect their own networks.
Here are a few steps you can take to mitigate the risk of these attacks:
Be sure to patch all devices and keep your applications updated
Enforce multi-factor authentication and strong passwords
Use perimeter and internal firewall protection along with antivirus software
Back up your data on a daily basis to ensure your information can be accessed after a cyber attack
Keep your staff informed on the latest threats and cybersecurity best practices
