A Trend Micro spokesman confirmed that the company's site had been hacked Thursday, saying that the attack took place earlier in the week. "A portion of our site -- some pages were attacked," said Mike Sweeny, a Trend Micro spokesman. "We took the pages down overnight Tuesday night -- and took corrective action."
On Thursday security vendor McAfee reported that more than 20,000 Web pages have been affected by the attack. The pages are infected with malicious code that tries to install password-stealing software on the PCs of people who visit the sites.
At least Trend Micro isn't alone among embarrassed security firms. In recent months a small security firm in India was serving up viruses from its site, and CA was also hit recently.
