Hackers jack thousands of sites, including U.N. domains
It's a repeat of earlier attacks that relies on an SQL injection, says Websense
"They're using the same techniques as last month, of an SQL injection of some sort," said Dan Hubbard, vice president of security research at Websense Inc., referring to large-scale attacks that have plagued the Internet since January.
Among the sites hacked were several affiliated with either the U.N. or U.K. government agencies, said Websense.
The exact number of sites that have been compromised is unknown, said Hubbard. He estimated that it's similar to the March attacks, which at their height infected more than 100,000 URLs, including prominent domains such as MSNBC.com.
"The attackers have now switched over to a new domain as their hub for hosting the malicious payload in this attack," Websense said in an alert posted yesterday to its Web site. "We have no doubt that the two attacks are related."
"Once loaded, the file attempts eight different exploits," noted the Websense warning, including one that hits a vulnerability in Internet Explorer's handling of Vector Markup Language (VML) that was patched in January 2007.
Maone also said "I told you so" in his blog post yesterday. In an August 2007 entry, he had said that rather than fixing the underlying security problems on the U.N. site, the agency had simply deployed a "pretty useless" firewall that masked the most obvious attack surface.
However, even the disinfected sites could fall victim again, Maone maintained. "The sad truth, though, is that even those 'clean' sites are still vulnerable, hence they could be reinfected at any time," he said.
"Web site owners have to start securing their code," Hubbard noted.
