Outline Email purporting to be from delivery company FedEx claims that a package en route to the recipient has been returned due to an addressing error and that he or she must open an attached file to print a mailing label in order to receive the package.
The email is not from FedEx. The claim that a package has been returned is a lie designed to trick recipients into opening the attached file. The attachment contains malware.

The reason of the return is - Incorrect delivery address of the package.
Attached to the letter mailing label contains the details of the package delivery.
You have to print mailing label, and come in the FedEx office in order to receive the packages.

According to this email, which claims to be from delivery company FedEx, a package en route to the recipient has been returned to the FedEx office due to an error in the package's delivery address. The email instructs the recipient to open an attached file which supposedly contains a mailing label that must be printed out and taken to a FedEx office to allow correct delivery of the package.
However, the email is not from FedEx and the claim that a package has been returned is a lie designed to fool the recipient into opening the attached file. The attachment does not contain a mailing label. Instead, it contains a malicious .exe file, hidden inside a seemingly innocuous .zip file, that can install malware on the user's computer. The malware can modify the registry on the infected computer, connect to remote servers and download and install additional malware. Wording of the malware emails may vary, although all make reference to a package that could not be delivered.
FedEx has published a warning about this threat on its website, noting:
Be alert for fraudulent e-mails claiming to be from FedEx regarding a package that could not be delivered. These e-mails ask the receiver to open an attachment in order to obtain the airbill or invoice for picking up the package. The attachment contained in this type of e-mail activates a virus. DO NOT OPEN the attachment. Instead, delete the e-mail immediately.
These fraudulent e-mails are the unauthorized actions of third parties not associated with FedEx. When FedEx sends e-mails with tracking updates for undeliverable packages, we do not include attachments.
The tactic is not new, and has been used almost continually by malware distributors since at least 2008. Other long running versions of the malware emails claim to be from United Parcel Service (UPS) rather than FedEx.
Users should be wary of any emails that claim that delivery of a package by FedEx or UPS has failed or been delayed. Do not open any attachments that arrive with such emails as they are likely to contain trojans or other malware. Do not click any links in such emails as they may lead to malicious websites that also contain malware.
