A total of 5.5 million Web pages on more than 560,000 Websites were infected
in the fourth quarter, according to new data, with evidence that attackers are
waging less noticeable exploits in order to remain under the radar.
Dasient, which compiled the data from its proprietary malware analysis tool
that gathers information on malware attacks on Websites, says the fourth-quarter
2009 numbers are actually a slight decline from the third quarter, when it found
more than 640,000 infected Websites and 5.8 million infected Web pages.
