Pharming Definition
Pharming is a form of cyber fraud that involves the malicious redirection of a trusted website to a malicious website.
This type of fraud mainly affects banking institutions because of this type of fraud design for data theft.
The pharming causes the victim’s computer to open the pharmacist’s website instead of the desired website.
Since pharming is a very secret method, many victims do not even notice that they have cheated until it is too late.
How do Pharming works?
- A common technique requires installing malware on the victim’s computer. It can happen when you visit fraudulent websites or download content from them.
- After the malware installed, it corrupts certain information on the victim’s computer, which in turn triggers the pharming attack.
- Computers keep a list of previously visited websites and IP addresses in a locally stored “hosts” file.
- The next time a user visits a saved website, the computer no longer has to request the IP address from the DNS server but can access the hosts’ file.
- Pharming malware changes the IP address stored in the hosts’ file so that the computer transmits data to the fake website instead of the real website.
