Online fraudsters have continued to expand their efforts this week to inject
iframe attacks into the optimized search results of major Web sites.
The attack abuses a common practice
among Web sites -- caching search queries -- an activity designed to
boost their rankings among major search engines, such as Google, according to security researcher Dancho Danchev. The attackers inject common search terms and an
iframe script designed to send victims to other sites hosting malicious code. The search term and
iframe redirect get cached in search engines such as Google.
