Drive-By Pharming In the Wild

Symantec reported Tuesday that the first case of drive-by pharming, in which a hacker changes the DNS settings on a customer's broadband router or wireless access point and directs the link to a fraudulent Web site, has been observed in the wild. The first drive-by pharming attack has been observed against a Mexican bank: 'It's associated with an e-mail pretending to be from a legitimate Spanish-language e-greeting card company, Gusanito.com,' says Symantec Security Response principal researcher Zulfikar Ramzan. Inside the e-mail is an HTML image tag but instead of displaying images, it sends a request to the home router to tamper with it.
