Cyber-criminals have infected UK Vodafone Clients with malware disguised as MMS through a wide-spread spam campaign. Customers receive an e-mail which allegedly comes from the company’s MMS service with a dangerous attachment.
When clicking on Vodafone_MMS.zip, users get infected with Trojan.Gamarue, which may steal personal information, download and execute arbitrary files, and do its updates without anyone even noticing it. After one click on the bogus MMS, users’ computers will “listen” to the control and command server run by cyber-criminals.
Gamarue may also spread to removable drives, so users should be careful when managing confidential documents through USB.
This type of malware has also been spreading in Germany in a separate spam campaign that infected users who clicked on a fake hotel booking reservation.
To stay safe on the Internet, users should never open spam e-mails or click on suspicious attachments. Having professional antivirus software installed and updated may keep them safe from e-threats as they appear.
