Malicious sites continue to use search engine optimization in an effort to rank higher in search engine queries in hopes of searchers trusting and clicking on the link, according to a report released last week from AV-Test. A Yandex search engine spokesperson told MediaPost the company supports new malware testing after the independent lab released finding from an 18-month study looking at malware being delivered by search engines Google, Bing, Yandex and others. Yandex wants to see the "methodology transparent and clear to avoid any misinterpretations," he said.
