Hackers jack thousands of sites, including UN domains

Among the sites hacked were several affiliated with either the UN or UK government agencies

Large numbers of legitimate Web sites, including government sites in the UK and some operated by the United Nations, have been hacked and are serving up malware, a security researcher said Wednesday as massive JavaScript attacks last detected in March resume.

"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, referring to large-scale attacks that have plagued the Internet since January.

Among the sites hacked, said Websense, were several affiliated with either the UN or UK government agencies.

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."

Although the malware-hosting domain has changed, it's located at a Chinese IP (Internet Protocol) address, just like the one used in March, Hubbard said. "It also looks like they're using just the one [hosting] site, but changing the link within the JavaScript," he added, talking about an obfuscation tactic that the attackers have used before.

When a visitor reaches one of the hacked sites, the malicious JavaScript loads a file from the malware-hosting server, then redirects the browser to a different page, also hosted on the Chinese server.

"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.

Another security researcher, Giorgio Maone, who also develops the Firefox add-on "NoScript," said late Wednesday that although the UK-based sites appeared to have been cleansed of the malicious JavaScript, the UN sites had not.

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 UN site, the agency had simply deployed a "pretty useless" firewall that masked the most obvious attack surface.

Even the disinfected sites, however, 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 agreed.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
