The Home Depot’s website was compromised by a piece of hidden code that redirected browsers to a site infected with malware. The site had been listed as malicious as far back as July, 2009 by Google and StopBadWare, an organization determined to curb the spread of and raise awareness about malicious software. There is currently no security risk to the Home Depot s website, but the hole exploited in the first place may still remain unpatched and the site may still be vulnerable. The company has not commented on the security breach.
