Hackers expand massive IFrame attack to prime sites
The massive attacks against hundreds of thousands of Web pages that started earlier this month has spread to some of the Internet's most prominent sites, including those for USA Today, ABC News, Target and Wal-Mart, researchers said today.
Dancho Danchev, the Bulgarian security researcher who first reported the attacks two weeks ago, said that the attacks had spread to a long list of high-profile sites, which have had their search results poisoned with malicious IFrame code. "The attack's been ongoing for almost a month now," Danchev said in an e-mail.
