Chinese Hackers Linked to Internet Explorer Breach

An elite freelance hacking team in China appears to be behind a recent security breach of Microsoft’s Internet Explorer, three U.S. security firms said, offering a new glimpse into the capabilities of Chinese hackers.

The attack has caused particular concern within the security community because it pointed out a hole in one of the most-used pieces of software in the world. Microsoft’s Web browser comes standard on machines running its Windows operating system.
