Charities and donors are being sent spoof emails containing a virus, purporting to be requests for payment from the Fundraising Preference Service.
A spoof email, sent to Civil Society News, was blocked because it was found to contain a virus which would download malware onto devices when users open an attachment claiming to be an invoice.
But the Fundraising Regulator does not invoice people for the FPS, which is funded via the levy on larger fundraising charities, and has reported the issue to Action Fraud.
Charities with fundraising spends of over £100,000 are being invoiced for the third year of the levy and these will come from [email protected]
The regulator said charities should call it on 0300 999 3407 or email [email protected] if they are concerned.
This is not the first time that scammers have attempted to impersonate the regulator. In September 2017 the regulator was forced to issue a similar warning at the same time as the year two levy invoices were being sent.
