Research and current trends show that nearly two-thirds of all new user attacks will come from malnets. Malnets (malware networks) are distributed infrastructures within the Internet that are built and maintained for the purpose of launching a variety of attacks against unsuspecting users over extended periods of time. They gather users, typically when they are visiting trusted sites, and route them to malware, via relay, exploit and payload servers that continually shift to new domains and locations. http://alrt.co/WHJWR1
Takeaway: By identifying and tracking malnet infrastructures, security researchers can link new servers and domains to known malicious components and block them at the source, before they are used to launch attacks. This negative day defense delivers the most comprehensive protection against Web-based threats.
