People in Guernsey are being warned to be on their guard against the latest scam to hit the island after one local business lost £17,000 to fraudsters.
Mandate fraud is when someone impersonates a supplier and tells the customer they have changed their bank details and asks for their record to be updated.
Islanders are now being advised to check the call is genuine by contacting the supplier on an official number on file or from their website.
The Economic Crime Division in Guernsey have issued the following advice on how to avoid mandate fraud:
Make sure the request is from the genuine supplier. Contact them using established contact details on file or from their website - don’t reply using the details provided in the request.
Use both email and telephone in case one has been hijacked by fraudsters.
Contact senders of larger invoices in advance of making payment to ensure details are correct.
Never leave invoices unattended in the office or on a desk.
Ensure your computer systems are secure and anti-virus software is up-to-date.
If you are concerned about the source of a call, ask the caller to give you a main switchboard number for you to be routed back to them. Alternatively, hang up and call them back using established contact details you have on file.
Check your bank statements carefully and report anything suspicious to your financial institution.
