Secure Ways to Verify Bank Account Changes

May 26, 2025

Financial professionals, ie. business owners, bookkeepers, accountants, and CFOs, are prime targets for cybercriminals using phishing scams to request fraudulent bank account changes. These scams can lead to significant financial losses if not detected early.

A notable case highlighting this issue is Mobius Group Pty Ltd v Inoteq Pty Ltd [2024] WADC 114, where the court ruled that the payer, not the recipient, bore the responsibility for verifying bank account changes. This case underscores the need for stringent verification processes to prevent financial fraud.  Recognising the warning signs and implementing verification measures is essential.

Warning Signs of Fraudulent Requests

  1. Urgency and Pressure | Scammers create a sense of urgency, pushing immediate action to avoid supposed disruptions. This tactic is meant to bypass standard checks.
  2. Unusual Communication | Requests from unfamiliar emails, slight domain name changes or unexpected bank details should raise suspicion.
  3. Lack of Documentation | Genuine requests should come with official paperwork or authorisation. Suspicious or altered documents signal a potential scam.

Best Practices for Verification

Verify with a Trusted Contact | Use a known phone number or in-person confirmation, not details from the email.

Require Dual Approval | Implement a two-person review for banking detail changes to minimise risk.

Use Secure Communication | Avoid confirming financial details via email; use encrypted or company-approved channels.

Train Employees | Conduct regular cybersecurity training to keep staff aware of evolving scams.

Maintain Vendor Records | Keep an updated database of verified vendor banking details and cross-check any change requests.

By staying vigilant and enforcing these verification steps, financial professionals can prevent fraud and protect their organisations. Taking proactive measures today ensures stronger financial security tomorrow.
