Security vendor Blue Coat has reported a 200 per cent hike in malnets over the past six months. Malnets will be responsible for over two-thirds of all Web-based attacks in 2012. Cyber-criminals build an extensive infrastructure comprised of thousands of unique domains, servers and websites that work together to funnel users to a malicious payload. Blue Coat estimates that Malnet infrastructures are designed to launch hundreds of simultaneous attacks on unsuspecting users. For the first nine months of 2012, there were nearly one million requests to command and control servers that were part of the largest malnet on the Internet.”]
