The fake notice asks the receiver to open an attachment (Case_06172016DNB.zip), print the complaint and respond before June 28th, but the attachment contains an .exe file, that is actually malware, detected by ESET as Win32/PSW.Fareit.a, a trojan that steals passwords and other sensitive information. The trojan attempts to send gathered information to a remote machine.
Receivers of this and similar emails are advised to mark them as spam and not open any attachments in emails from unverified sources, no matter how official they look.
