Cyber Attacks on Accounting Software - How to Protect Your Financial Data
Michael Tunstall
Cyber criminals don't just target large organisations.
Small and medium-sized businesses are increasingly being targeted because they often hold valuable financial information but have fewer security controls in place.
For many businesses, Xero contains years of financial history, customer information, supplier details and sensitive business data. If attackers gain access to this information, the consequences can be costly.
Fortunately, there are practical steps every business can take to reduce the risk.
Why Accounting Software Is a Target
Financial systems are attractive to cyber criminals because they contain valuable information and are often connected to other business systems.
A compromised accounting platform could expose:
Customer and supplier details
Bank account information
Payment history
VAT records
Payroll data
Financial reports
Company contact information
Attackers may attempt to steal information, manipulate records or use your account to commit payment fraud.
Common Cyber Threats
Phishing emails
The most common attack starts with an email designed to trick someone into revealing their login details.
A convincing message may appear to come from Xero, Microsoft or even one of your suppliers.
Stolen passwords
If passwords have been exposed in a previous data breach and are reused across multiple services, attackers may be able to gain access without needing to hack anything.
Weak passwords
Simple or commonly used passwords remain one of the easiest ways for criminals to access business systems.
Malware
Malicious software installed on a computer can steal credentials or give attackers access to sensitive business information.
Business Email Compromise
Cyber criminals may gain access to email accounts before attempting to change payment details or intercept invoices.
How to Better Protect Your Xero Data
Good cyber security doesn't rely on a single product.
Instead, it combines multiple layers of protection.
Enable Multi-Factor Authentication
Multi-Factor Authentication (MFA) provides an additional layer of security beyond your password and should always be enabled.
Use unique passwords
Every business account should have a strong, unique password that isn't used anywhere else.
Password managers make this much easier to manage.
Limit user access
Only provide employees with the permissions they genuinely need.
Review user accounts regularly and remove access when staff leave the business.
Keep software updated
Regular software updates help protect against known vulnerabilities that attackers may try to exploit.
Provide cyber awareness training
Most successful attacks begin with human error.
Helping employees recognise phishing emails and suspicious activity significantly reduces risk.
Why Backup Is Still Essential
Even with strong cyber security, no organisation can eliminate risk completely.
If an attacker gains access to your Xero account, they may:
Delete accounting records
Modify financial information
Remove contacts
Alter invoices
Change supplier details
Without an independent backup, recovering this information may be difficult.
A dedicated backup solution provides a secure historical copy of your accounting data, allowing you to recover important information if something unexpected happens.
Building a Layered Defence
The most resilient businesses combine good cyber security with reliable backup.
Together they provide protection against both prevention and recovery.
Think of it this way:
Cyber security helps stop attacks.
Backup helps you recover if something gets through.
Both are essential parts of protecting your financial information.
