Security Advisory: "You have voicemail!" malware

Threat Level: Medium
Threat Type: Malware Risk
Advisory Date: 07/04/2019

Description

Univeristy of Regina email users should keep their eyes peeled for a phishing attempt which trys to appear as a legitimate, automated the voice mail service. The message has a subject line “You have received a voice mail from 603-###-####”. The body of the email contains the fake data about the voicemail and caller, and a link to download the voice message. The link will download malware onto the user’s computer.

Scammers earn the trust of the recipients through social engineering tactics, such as including information that looks correct and appropriate to be receiving in the visual voicemail email. An “Email ID” that appears to be coming from an internal email address at the recipient’s organization, as well as a “Download Message” link that appears to host the fake audio file on the recipient’s organization’s domain, are throwing off recipients and causing them to trust the email enough to click on the download link.

The message is not legitimate and does not originate from the University of Regina.  There is no voice mail to be retrieved.

In this case, note that the sender is not a valid email address, and the link to the voice mail message is a suspicious looking URL, as circled in blue.
