Recent flood of spam that looks like it comes from us

A number of faculty and staff members have received spam in the last few weeks that typically looks something like this:

Dear Customer,

Unless it comes directly from the email account of someone from Technology Services please ignore the message and delete it.  And whatever you do, do *NOT* download and/or open the attachments or follow any URLs included in the messages.  It's likely the URLs will lead you to a phishing site.
