VoIP voice mail scam

Scammers sending malware disguised as voice mail messages to UD email inboxes


3:10 p.m., Nov. 18, 2013--A new scam has been reported at the University of Delaware due to a new feature available through VoIP telephones -- the VoIP system allows voice mail messages to be sent to an email address as a .wav file.

However, this features is not automatic and must be activated by Telephone Services. If you have not called Telephone Services to activate this feature, then any email messages claiming to be voice mails are a scam.

  • does not send group messages. 
  • An authentic voice mail message is a .wav file, not a .zip file. 
  • An authentic caller will either appear as a name or “Wireless caller.”
  • An inauthentic caller will generally appear as “Unknown Caller.”
