Sophos | Security threat report 2012
From the Foreword:
“Over the past year we in the IT security industry have seen a growing awareness of the work we do. In 2011, a number of highly visible cyberattacks made news headlines around the world, but the underlying problem affects us all. It seems that the cybercriminals are getting bolder in their attacks as the availability of commercial tools makes mass generation of new malicious code campaigns and exploits easier. The net result has been significant growth in volume of malware and infections.”
