Members of many University email lists are reporting that they are receiving email messages allegedly sent by the list that are then being returned to the members of the list. These “returned” messages contain a copy of an infected attachment, usually stripped out by the Google Apps at UD and UD Exchange email servers.

If you see a sample message like the one shown here, just delete it. If you see one with the attachment still present, delete the message and be certain that you do not open the attachment.
As always, be suspicious about email messages that contain attachments. Last week, we reported that PowerWare ransomware was being distributed via infected MS Word attachments to email.
Note to UD mailing list owners
If you are the owner of either a UD manually maintained or Mailman email list, you can stop these annoying messages to your list members by converting your list to a Google Group. The names of manually maintained and Mailman lists can be obtained easily; a Google Group within Google Apps at UD can be set up so that its name is not visible to those outside the group.
It’s possible that you could also use a UD P. O. Box mailing list to send a message to closed, pre-defined groups of employees or students.
Sharing files
If you have files you need to share with a colleague, consider using a more secure method of sending the file than attaching it to email. For example, you could email your colleagues that you will be sharing a file with them, then log in to UD’s Dropbox service to send them the file.
