More than 1.2 million Web sites were infected by malware in the third quarter of 2010, according to security firm Dasient. This includes legitimiate sites belonging to government agencies and “malvertisements,” or malicious advertisements.
More than 1.5 million “malvertisements”—or ads and widgets whose sole purpose is to spread malware—were served online per day, according to Dasient’s data. This number includes both drive-by-downloads and fake anti-virus, said Daswani. These campaigns are also fairly long-lived in Internet time, lasting an average 11.1 days, according to the report.
