ATO Holiday Cyber Safety Alert: Secure Your Workplace Before the Break

With offices closed or operating with minimal staff, businesses become easier targets for fraud, theft and cyber attacks. 

Preparing now can help you avoid costly disruptions and protect your clients’ data while you enjoy your time off. 

Key Risks to Be Aware Of

Cyber incidents are more common during holiday shutdowns because: 

• Devices are left unattended 
• Fewer people are monitoring emails or suspicious activity 
• Systems may be left logged in or not updated 
• Staff may be away and unavailable to verify payment requests 

Criminals often take advantage of reduced oversight — so tightening your security before you close is critical. 

Simple Steps to Stay Cyber-Safe 

Take a few minutes to complete this essential checklist: 

• Lock all devices and ensure strong passwords or passcodes are in place 
• Log out of accounting, payroll and internet banking systems 
• Store laptops and devices securely — not left visible on desks 
• Apply software updates before the break 
• Turn on multi-factor authentication (MFA) for important systems and accounts 
• Be cautious of emails requesting payments or changes to bank details 

These small actions greatly reduce the risk of fraud, ransomware and unauthorised access. 

Record-Keeping and System Controls Matter 

Before the break, review: 

• Who currently has system access 
• Whether former employees still have login credentials 
• How passwords are managed 
• Whether backups are up to date and stored securely 

Incorrect or outdated user access is one of the most common causes of business identity theft.
