Iframe works by injecting malicious code into web pages and
accounts for nearly two thirds of the world's infected web
pages.
In June an Iframe attack on multiple Italian websites occurred,
making headlines around the world.
More than 10,000 web pages were infected, most of which were on
legitimate but compromised websites hosted in Italy.
Victim websites included Italian city councils, employment
services and tourism sites. Most of the affected pages appear to be
hosted by one of the largest ISPs in Italy.
