Please beware of emails claiming to come from HMRC saying that they are a Tax Refund Notification. Here at Mazuma several of our staff have even had them! They may look like the email below. This particular one came from the email address firstname.lastname@example.org.
Please note that HMRC do not send notifications of a tax rebate by email, or request that you update your security certification.
You can find full details of all the known HMRC related phishing scams at the HMRC website but please be vigilant.
