More IE security woes: Attacks appear imminent as exploit is improved

From InfoWorld: Hackers working on the open-source Metasploit project have spiffed up a zero-day attack on Microsoft's Internet Explorer, making it more reliable -- and more likely to be used by criminals.

Security experts have been worried about the flaw since it was first disclosed on the Bugtraq mailing list Friday. But the original demonstration code was unreliable and has not been used in real-world attacks.

"The Metasploit exploit that was released last night will be more reliable against certain attacks than the initial exploit," said Ben Greenbaum, senior research manager with Symantec, in an interview Wednesday.

As of Wednesday morning, Symantec had not seen the exploit used in Internet-based attacks, but security experts say this type of code is for a very popular hacking technique called a drive-by attack. Victims are tricked into visiting Web sites that contain malicious code where they are then infected via the browser vulnerability. Criminals also place this type of code on hacked Web sites in order to spread their attacks.

On Monday, Microsoft published a Security Advisory on the flaw, offering some workarounds for the issue. It affects IE version 6 and version 7.
