Malicious hackers have broken into several sections of BusinessWeek.com and are now using the popular site to redirect visitors to malware-laden servers.

At the time of writing, hundreds of pages on BusinessWeek.com have been rigged with malicious JavaScript pointing to third-party servers. Visitors to the site execute the script, which attempts to launch drive-by malware downloads.

Firefox 3's malware blocker is detecting some of the infection attempts but there are numerous malicious pages currently bypassing the browser's blacklist-based filter.

The use of legitimate Web sites in drive-by malware attacks has soared in recent months.  According to expert estimates, at least 70 percent of all  Web-based malware is now being hosted on legitimate Web sites.  Some recent high-profile targets included Bank of India, China.com, and USA Today.
