MessageLabs Intelligence June and Second Quarter 2008: Web Threats Peak to Highest Level in One Year
MessageLabs, the leading provider of messaging and web security services to businesses worldwide, today announced the results of its MessageLabs Intelligence Report for June 2008. Analysis highlights that the number of new malicious websites blocked each day has risen by 58 percent in June to its highest level since April 2007. The rise in malicious websites, according to MessageLabs, is linked to a rise in the number of spyware and adware sites being blocked.
"Web-based malware has become a dangerous tool in the arsenal of cybercriminals," said Mark Sunner, Chief Security Analyst, MessageLabs. "The bad guys know that web-borne attacks are unchartered territory for many computer users and are taking advantage of this in addition to vulnerabilities and weak security in web applications. Businesses that allow employee access to any web site and sites with webmail accounts that haven't been scanned by corporate security systems are at particular risk."June also saw some new and unusual spam topics capitalizing on insults and celebrity mentions in the subject lines to grab attention and drive recipients to action. One spam run, originating from the Storm botnet, used personalized insults like 'what a stupid face you have' to annoy recipients. The message contains a link to the Dogpile search engine that when activated re-directs to a malware site that has been compromised to host a video.exe file. The search-engine redirect functions similarly to how the Google "I Feel Lucky" link was abused earlier this year.
Another spam cluster used celebrity references to entice recipients into clicking on a link that directed to the same compromised domain with a smattering of licentious headlines including names such as US Senator and Democratic US Presidential candidate Barack Obama. However in this run, the link displayed a page from the PornTube site, a family of porn sites that specialize in YouTube-like content, requiring recipients to download the same Storm-generated executable file, video.exe. The volume of interceptions accounted for more than 18 percent of all spam during the periods it was sent.
"This is not the first attack of this kind we have seen," Sunner said. "In April, MessageLabs stopped a similar attack spoofing YouTube videos, not mailed out as links but distributed via user-generated content sites like blogs and links posted on comments pages. This is testament to the fact that spammers are using content that historically works, but vary the distribution tactics so as to go relatively unrecognized in their motives."
During Q2, activity from the Storm botnet declined to a quarter of prior volumes from 20 percent in Q1 to less than 5 percent in Q2 forcing spammers to turn to rival botnets like Srizbi which is now responsible for around 40 percent of all spam. With emails that used headlines pertaining to the Beijing Olympics and earthquakes in China, the spammers returned to traditional ways of spreading Storm malware via a link to an IP address of an already compromised machine.
Other report highlights:
Web security: Analysis of Web security activity shows 31.4 percent of all web-based malware intercepted was new in June.
