Blackmail emails in circulation

The NCSC is currently receiving reports of emails in which blackmailers claim to be in possession of credit card details, driving licence details, social security numbers and other data. They threaten to sell this information on the dark web. The emails often appear to come from the recipient's own address. However, this is not the case. The sender address is fake. The email is a bluff. Ignore it and do not be intimidated.
