Police in Fife are issuing a security warning to local businesses in the Kingdom following a high-value fraud.
The warning comes after a builder was contracted to carry out work in Chance Inn to construct a new home in the area.
Then the customer received an email providing details of a new bank account to transfer over £45,000.
Police then received a call from the builder after he did not receive the money and did not send out an email with different bank details.
Sergeant Stuart Hay of Cupar Police Station said: "The clients received an email from the trusted email address of their builder and complied with the request to send payment to a new account. It was not until the builder found that no new funds had been deposited in his bank that the hack was identified and our investigation is now underway to identify those responsible.
"For small local firms, the loss of such high revenue could be disastrous and we would urge all businesses to make sure their email accounts, websites and all other means of engaging with customers have all the necessary security in place to safeguard themselves against hackers and scammers.
"For members of the public, the loss of such money can have life changing implications and we would urge the public to remain vigilant against this type of crime, checking the authenticity of material changes to where payments are sent.
"If you have information relating to this incident please come forward immediately."
Inquiries are ongoing and police are urging anyone with information to contact them on 101 and quote incident number 712 of the 6th June.
Alternatively, an anonymous report can be made to the charity Crimestoppers on 0800 555 111.
