Although the site was up as late as early Friday morning, later in the day it was inaccessible. Multiple security firms confirmed that the site was down, and TechWeb was also unable to reach the site.
"The [hacker] domain is no longer available," said Ken Dunham, director of malicious code research at iDefense. "Although it could be due to high levels of traffic to the site, it's more likely it's been made unavailable because of the malicious content it was hosting." McAfee's virus research manager, Craig Schmugar, also confirmed that the site was down.
While that eliminates the immediate threat to Internet Explorer users -- with the site offline, nothing can be downloaded to compromised machines -- this is nowhere near the end of the story, said security experts.
