Whenever you type an address into an Internet browser, that address is instantly resolved into the site's numerical Internet address by a DNS server located somewhere in the world. On Tuesday, Symantec announced that online criminals have started to remotely redirect your home network router's DNS server so that whenever you type in a financial institution or other trusted site, your browser will instead be redirected to a bogus or phishing Web site.
The practice, called pharming, usually attacks the DNS servers directly, but this latest attack brings it all home (if you are using broadband connectivity). Fortunately, the routers and institutions affected by this current attack are limited to one country, Mexico, but Symantec warns that word of this real-world attack could bring similar attacks elsewhere.
Last year, researchers at Symantec and the University of Indiana reported that remotely changing a home router's DNS server was theoretically possible. The theoretical attack used Javascript on a specially crafted Web page, and affected only wireless routers. The attack in use today uses e-mail, and it can affect non-wireless routers as well.
