Starting at approximately 10am GMT, users of the popular business-focused social networking site began receiving emails with a fake contact request containing a malicious link. According to Cisco Security Intelligence, these messages accounted for as much as 24% of all spam sent within a 15-minute interval today. If users click, they are taken to a web page that says “PLEASE WAITING.... 4 SECONDS..” and then redirects them to Google, appearing as if nothing has happened. During those four seconds, the victim’s PC was attempted to be infected with the ZeuS Malware via a “drive-by download” – something that requires little or no user interaction to infect a system.
