All businesses and many individuals get these scam emails.
The emails are made to look as if from a reputable company sending you a bill for some product or service you have received. The bill is usually a file attachment. Maybe a .doc file or ,zip or .exe or .php. Do not open any of these as they can contain viruses.
The scam relies on businesses processing the bill as if it was genuine and only realising when too late that it wasn’t for a genuine product or service received.
With individuals they rely on people opening the attached file or clicking on the link. The attachment may contain a virus that will infect your PC or the link may take you to a bogus website designed to steal your identity or financial information.
How do you tell if the email is genuine or a scam?
The simple answer is if you are not expecting such a bill then assume it is fake and delete the email. Do not open the attachment to see what it is – especially if it is a .zip file or .exe file or .php link
These scams only work if people don’t pay attention – don’t be caught out.
