Pharming attacks are similar to phishing attacks in that they are designed to extract confidential data from victims by pretending to be a trusted source and requesting information.
The difference is that pharming attacks resolve the victim’s DNS to a malicious server when attempting to visit a legitimate website. Pharming can be conducted either by altering the hosts file on a victim’s computer or by exploitation of a vulnerability in DNS server software. Redirects of this nature are often facilitated by malware already downloaded and installed on the victim’s machine and represent a one-to-many attack directed at the widest possible network of victims.
It is a form of online fraud very similar to phishing as pharmers rely upon the same bogus websites and theft of confidential data.
