"The number of malicious Web sites has skyrocketed over the past few
months, going from 5,000 new ones a day in April to nearly 30,000 a day
now.
"This certainly is a huge increase," said Carole Theriault, a
senior security consultant with Sophos, Inc., in an e-mail to
InformationWeek. "In June, we saw it climb to 9,500 a day and then this
huge jump up 29,000."
"The IFrame malware was a major Web site infector in June.
IFrame, which injects malicious HTML files onto Web pages, actually
topped Sophos' chart for June's Top 10 Web Threats, accounting for
nearly two-thirds of the world's infected Web pages. Earlier this
month, hackers used the IFrame to attack multiple Italian Web sites.
Sophos reported that more than 10,000 Web pages were infected in the
attack, most of which were on compromised legitimate sites hosted in
Italy. Victim Web sites 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, noted Sophos. "
