Microsoft rushes fix for Internet Explorer vulnerability
Microsoft on Monday is planning to distribute an emergency fix for an Internet Explorer (IE) vulnerability that is being used in targeted attacks.
The software giant announced Sunday that it would release a single "critical" patch for the issue, which affects all supported IE 6, 7 and 8, but not version 9. Microsoft previously issued a temporary workaround.
The flaw became known last month when it was used as part of a so-called "watering hole" attack against the website for the policy think tank Council on Foreign Relations, the influential membership group that helps shape U.S. foreign policy.
Security firm Symantec has linked this exploit and others taking advantage of the IE bug to a string of recent espionage attacks spearheaded by a group of hackers dubbed the "Elderwood Project," possibly based in China.
Microsoft has acknowledged in an advisory that the vulnerability has been used in a limited number of targeted attacks. At least one other organization, Chatsworth, Calif.-based microturbine systems supplier Capstone Turbine Corp., had its website compromised to take advantage of the bug, security researcher Eric Romang has in a blog post.
