Campbell, Calif., March 3, 2011 -- Barracuda Networks Inc ., a leading provider of content security, data protection and application delivery solutions, today released findings from its 2010 Annual Security Report which indicates attackers are making a shift from using email spam to more aggressively targeting the Internet. Email spam dropped by half during 2010, while search engine malware doubled and the Twitter Crime Rate increased 20 percent, signifying a concentrated focus on the more lucrative social networks and search engines as attack vectors. To help combat this, Barracuda Networks today announced the availability of its new Profile Protector, a free service that protects social networking users against malicious threats on Facebook and Twitter. “Attackers focus on where they can get the most eyeballs and profit, and today that means social networks and search engines,” said Dr. Paul Judge, chief research officer at Barracuda Networks. “As a community we often point to the need for user education as the missing component; however, the levels of social engineering involved in today's attacks suggest that we must continue to elevate our technological approaches. The research community must continue to build innovative defenses and the industry must make efforts to increase the deployment rates of those defenses.” Searching for Malware Barracuda Labs conducts periodic studies across Bing, Google, Twitter and Yahoo!, analyzing trending topics on popular search engines in order to understand the scope of the problem and to identify the types of topics used by malware distributors. The most recent study was conducted over 153 days. The analysis reviews more than 157,000 trending topics and nearly 37 million search results. Overall, the research found that attackers have increased the amount of search engine malware as well as expanded targeted efforts beyond Google. Key highlights from the search result analysis include:
