pharming - Computer Definition
An Internet scam that involves misdirecting a user to a fraudulent Web site or proxy server by exploiting weaknesses in DNS (Domain Name Server) server software and hijacking transactions, or by changing certain files in the client software on a victim's computer.The term pharming is a play on farming and phishing. (Hackers commonly replace f with ph, phor reasons that are entirely unphathomable to the rest of us.) See also e-mail, hyperlink, Internet, phishing, pretexting, scam, social engineering, and spam.
Setting up a fraudulent website that contains copies of pages from a legitimate website in order to capture confidential information from users. By hacking into DNS servers and changing IP addresses (see DNS hijacking), users are automatically redirected to the bogus site, at least for some period of time until the DNS records can be restored. For example, if a bank's DNS were changed, users could be redirected to a website that looks familiar. The bogus site could just collect usernames and passwords, or it could allow access to the site and, using some pretense, request financial information. Unlike phishing schemes that use e-mail to make people go to the phony site, pharming is more natural. Users are going to the site on their own and are certainly not suspicious because the pages look familiar. See phishing and DNS hijacking.
