The website for security software firm Trend Micro was among the hundreds of legitimate websites to fall victim to a widespread web attack that has spread malicious software around the web this week.
A spokesman yesterday confirmed that the company's site had been hacked, 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.
Researchers are still not sure how the attackers are managing to hack these web pages, but the pages all seem to use Microsoft's Active Server Page (ASP) technology, which is used by many web development programs to create dynamic HTML pages. A software bug in any of those programs is all the attackers need to install their malicious code.
If the code is successful, it then installs a password-stealing program on the victim's computer that looks for passwords for a number of online games, including the Lord of the Rings Online.
It's embarrassing when security vendors fall victim to the attacks they are supposed to prevent, but Trend Micro is not the only company to have had its website hacked in recent months. In January, parts of CA's website were infected with a very similar type of attack.
