Hackers exploit latest IE zero-day with drive-by attacks

Hackers are exploiting the just-disclosed unpatched bug in Internet Explorer (IE) to launch drive-by attacks from malicious Web sites, security researchers said today.

"This attack appears to be rather targeted at the moment, but as with other unpatched vulnerabilities in the past, this has the potential to explode now that the word is getting out," said Craig Schmugar, a threat researcher at McAfee, in a blog post today.

Attacks are launched from Web sites in a classic drive-by fashion, said Schmugar and others. "Visiting the page is enough to get infected," Schmugar said.

Symantec also confirmed that it has spotted in-the-wild attacks exploiting the critical vulnerability in IE6 and IE7 that Microsoft acknowledged yesterday. "We're still seeing just limited attacks," said Ben Greenbaum, a senior research manager with Symantec's security response team. "The exploit is carried out simply by visiting a Web page hosting the vulnerability," he continued. "When the browser opens the page, the exploit causes the user's computer to download and execute another piece of malware."
