Malicious sites increase 240% | Social Media and its influence |
In 2011, the most significant evolution in the threat landscape was the use of malware networks, or malnets, to launch highly dynamic Web-based attacks, according to Blue Coat Systems.


These complex infrastructures, which outlast any one attack, drove a 240% increase in the number of malicious sites during the year and are expected to launch as many as two-thirds of all new attacks in 2012.
