The Better Business Bureau warns businesses across the U.S. and Canada of a spoofing scam using the BBB name and a false BBB email address to entice recipients to access potentially damaging hyperlinks. 

The most recent e-mail has a false return address of consumer-complaints@bbb.org and a phishing hyperlink citing a BBB complaint case number, for example, "DOCUMENTS FOR CASE #BBA749BED0". These links actually direct access to a subdirectory of the hacked firm’s website where users are asked to download documents related to the complaint. The download is actually an executable file that is believed to be some form of a computer virus.

All recipients are advised that any e-mail from the consumer-complaints@bbb.org address is not coming from any BBB and should be considered counterfeit. The BBB strongly encourages recipients of any such message to delete the message immediately without clicking on the "DOCUMENTS FOR CASE" links.

So be careful and delete any such messages.  If you receive a complaint from the Better Business Bureau you will generally be notified by letter and you will have some advance warning of the complaint.
