similar to this:

We discovered a new potential threat that we term "Drive-by Pharming".
An attacker can create a web page containing a simple piece of malicious
JavaScript code. When the page is viewed, the code makes a login attempt
into the user's home broadband router and attempts to change its DNS
server settings (e.g., to point the user to an attacker-controlled DNS
server). Once the user's machine receives the updated DNS settings from
the router (e.g., after the machine is rebooted) future DNS request are
made to and resolved by the attacker's DNS server.
