wiredmikey writes "On Monday morning, cybercriminals began sending massive volumes of spam email messages targeting LinkedIn users. 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 redirected to Google, appearing as if nothing has happened. During those four seconds, the site attempted to infect the victim's PC with the ZeuS Malware via a 'drive-by download' – something that requires little or no user interaction to infect a system."
