Microsoft Internet Explorer users are being warned that one site claiming to host a new version of the web browser is not what it looks like.
Hackers have set up a malicious website that installs a trojan via a browser exploit, according to a news release from SurfControl.
The trojan "effectively creates a backdoor on the infected system," according to the Scotts Valley, Calif. anti-virus vendor.
To be victimized by the trojan, users must click on a link provided in the spoofed email, which appears to come from a Microsoft support address and offers users the chance to download Internet Explorer 7 (IE 7) Release Candidate 1.
Microsoft just this week released IE 7, promising strengthened defenses against phishing websites and other malicious attacks.
Susan Larson, vice president for global threat analysis and research at SurfControl, told SCMagazine.com today that the scam has a good chance of success because of its timeliness and the craftsmanship of the malicious site.
"It takes advantage of the current event of Microsoft IE 7 being released. It took advantage of that topical event, and it took advantage of Microsoft saying (users) needed an upgrade," she said. "The other thing is that it is a fairly well spoofed site, and it looks good, very Microsofty. It's a drive-by. Basically you click on the link and you're immediately starting to download the exploit."
