The US Department of Justice (DOJ) is alerting email users about a possible phishing attack using messages that claim to be from the DOJ.

The DOJ said the emails may have the subject field or be addressed ‘Dear Citizen’. It also said the messages may refer to a fraudulent US Internal Revenue Service case filed against the recipient, and may contain a DOJ logo in the body of the mail or as an attachment.

The DOJ said the email is a hoax, and asked recipients to neither open the message nor download any attachments that come with it, and delete the message immediately. The department said it would not contact users about such matters via email.

Anyone receiving the email is asked to file a complaint via a DOJ website.
