A hacker has posted attack code that could be used to break into a PC running older versions of Microsoft's Internet Explorer browser.

The code was posted Friday to the Bugtraq mailing list by an unidentified hacker. According to security vendor Symantec, the code does not always work properly, but it could be used to install unauthorized software on a victim's computer.

"Symantec has conducted further tests and confirmed that it affects Internet Explorer versions 6 and 7," the company wrote on its Web site Saturday. "We expect that a fully-functional reliable exploit will be available in the near future."

Security consultancy Vupen Security has also confirmed that the attack works, saying it worked on a Windows XP Service Pack 3 system running IE 6 or IE7. Neither company was able to confirm that the attack worked on Microsoft's latest browser, IE 8.
