THREE CYBER THREATS SET TO IMPACT AUSTRALIAN BUSINESSES

Adopting effective cyber security processes is more important than ever.
Three cyber threats to watch out for:
​
1. Destructive malware
The Australian Cyber Security Centre (ACSC) has identified an increase in destructive malware targeting businesses.
To protect your business from malware:

• Keep your devices updated with effective security and anti-virus software.
• Use a non-administrator account whenever possible and be extra cautious about opening email attachments or images.
• Never click on links or pop-up windows or download anything you’re not familiar with.
• Limit file-sharing where possible.

2. Ransomware
Cybercriminals are increasingly using ransomware to lock files so the owner of the device can no longer access them.  
Signs that you’ve been affected by ransomware include: pop-up messages requesting funds or payment to unlock files; you cannot access your devices, or your login doesn’t work for unknown reasons; files request a password or a code to open or access them.

Alternatively, files being moved to different locations on a device, or files suddenly having their names or icons changed. This all indicates possible ransomware intrusion.

To protect your business from ransomware:

• Do not visit unsafe or suspicious websites.
• Do not open emails or files from unknown sources.
• Do not click on malicious links in email or on social media.
  

3. Targeting of network devices

The ACSC has identified an increase in targeting of Cisco devices using the Smart Install feature worldwide, including in Australia.
To protect your business from being a target:

• Secure Cisco features to mitigate against this activity.
• Protect your information by using a screen lock, encryption and regularly backing up files.

• Use secure software and make sure it is up-to-date
• Be careful in using public Wi-Fi networks, especially when doing tasks that require credit card information, such as online banking.
