Number of Malicious Sites Increase by 240% in 2011

Blue Coat Systems issued its Blue Coat 2012 Web Security Report that identifies and analyzes trends in malicious attacks over the past year and makes recommendations on strategies to keep companies safe.  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.  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.

The Blue Coat Security Labs team first discovered the existence of these malicious networks early in 2011 and presently is the only company to specifically identify, track and block them.

Malnets are distributed network infrastructures within the Internet that are built, managed and maintained by cybercriminals for the purpose of launching a variety of attacks against unsuspecting users over extended periods of time.

The Blue Coat 2012 Web Security Report details the strategies and tactics that malnet operators deploy to snare users and funnel them to dynamic malware payloads, or software which surreptitiously installs on users computers designed for malicious or criminal purposes.

“With the average business now facing 5,000 threats per month, identifying and tracking malnets to block attacks at the source before they are launched is the most effective protection.

According to the report, the most common entry point into these malicious infrastructures rely on the path of least resistance, utilizing entry points that are easy to exploit, such as search engines/portals and email, or are utilized by large, diverse populations of users.

The 2012 Web Security Report examines the malnet ecosystem in depth, examining user behavior, malnet strategies and tactics, as well as highlighting the best defenses against these aggressive infrastructures.
