CERT has had a number of reports of a "Job Scam" phishing attack. Please inform your users not to reply or engage this email (please see example message below).

It's drawing to the close of the financial year, and the scammers are out in force pretending to be from HMRC phishing for your bank details so they can issue you a "tax refund" or similar. Don't fall for that old trick - HMRC never issues refunds by email. Our security team works hard to block the payloads of all phishing emails received, but these blocks only work if you're using the University's data network. If you are away from Cambridge over Easter and using your own internet provider's connection, you won't have this added layer of protection. As ever, assume it's fraudulent until you can prove otherwise, and don't click any links. This is an example of the type of email to look out for:
