Online Ad Sales Open Door to Viruses

From The Wall Street Journal (Emily Steel)
On a Saturday night at the end of May, visitors to the forums section of Digital Spy, a British entertainment and media news Web site, were greeted with an ad that loaded malicious software onto their computers. The Web site’s advertising system had been hacked.

The crooks behind the site infect PCs (or pay others to do so) with the Golden Cash remote-control malware, and then sell access to those PCs. And that access doesn’t cost much.  Read the full story [pcworld.com]
