According to the US Security Ooperations Center of the Administrative Office of the US Courts, 'the emails are instructing recipients to report to a hearing on a specified day and time. The emails also instruct recipients to review an attached document for detailed case information. When the attachments or links in the email are opened,  a malicious program is launched that infects the recipient's computer'. The Center says, however, that unless a person has 'consented to receive court notifications electronically' and unless they are also 'actively involved in a case' in a federal court then 'you will generally not be served with court documents electronically'.
