Web infection attacks more than 100,000 pages
UK Civil Service, UN and EPA among the plagued
Hackers have injected malicious code into hundreds of thousands of reputable web pages, turning them into launchpads for attacks that silently install malware on the machines of those who visit them. The UK's Civil Service and the United Nations were among those who had been hacked.
Websense, which wrote about the mass infection  Tuesday, said the attackers perpetrated a similar assault a few weeks ago on news and travel sites. Little is known about the group responsible, except that they're using the nihaorr1.com domain name, which appears  on the surface to be registered to someone in Shanghai.
Users visiting an infected site will be redirected to a series of sites that eventually tries to exploit eight different vulnerabilities, all of which have been patched.
We've written plenty about vulnerabilities in browsers, media players and other types of software that are triggered only after the mark visits a website under the control of the attacker. Almost inevitably, a Reg reader comments that only a fool would be drawn to such a place. As mass infections like this one make clear, anyone who visits pages belonging to well-known news and travel sites, the United Nations or governmental agencies on either side of the Atlantic is susceptible.
So if you haven't patched that old version of iTunes or AIM in a while, now might a good time. ®
