Pharming is a type of malicious social engineering attack in which criminals redirect Internet users, who are trying to reach a specific website, to a different, fictitious website. This is done by using social engineering techniques. They attempt to obtain personally identifiable information (PII) and log-in credentials from victims. This includes passwords, social security numbers, payment information, and so on.
They may also attempt to install pharming malware on the victim’s computer through the use of ‘spoof’ websites. With the ultimate goal of stealing personal information, fraudsters frequently target websites in the financial sector, such as banks, online payment platforms, and e-commerce websites.
Pharming takes advantage of the way people use the Internet. To understand how pharming works, you need to know how Domain Name Systems (DNS) servers function.
DNS servers are responsible for converting domain names into IP addresses. An IP address identifies the destination of a web server, whereas a domain name serves as the website’s address. After that, your web browser establishes a connection with the IP address that the server identifies.
Once you have visited a particular website, a DNS cache is created, which eliminates the need for you to visit the server each time you return to the site. Pharming has the capability of corrupting both the DNS cache and the DNS server. Two types of pharming can result from this.
In this case, you may have received a Trojan horse or virus through a phishing email or malicious download. When you type in the address of the website you intended to visit, the malware secretly redirects you to a fraudulent site created and controlled by cybercriminals.
In this type of pharming, a malicious code is sent to your computer via email. This can modify your computer’s local host files. After that, these corrupted host files can direct your computer to fraudulent websites. This is regardless of the Internet address that you type into your web browser.
Internet computers, or DNS, are responsible for directing your website request to the appropriate IP address. In contrast, a malicious, corrupted DNS server can direct network traffic to an erroneous IP address that has been assigned to it.
This pharming scam does not rely on corrupting individual files. Rather, it depends on exploiting a vulnerability at the DNS server level to carry out its malicious activity. You reach fraudulent websites without realising it because there has been poisoning of the DNS table.
The corruption of a large DNS server opens the door for cybercriminals to target and scam an even larger number of victims.
The following are signs that you are a victim of pharming:
The address bar gives another hint. Even if the difference between the domain you typed in and the one you clicked is subtle, the domain will be different. Fraudsters make minor tweaks to the name to make it more appealing. Some common methods of pharming are: removal of a letter, the substitution of letters (for example, an uppercase ‘I’ in place of a lowercase ‘l’), the use of the Cyrillic script or other non-Latin characters that look similar to the characters they’re attempting to duplicate.
Check to see if the web address has the lock symbol to the left of it, as well as any other security features. A lock appears to indicate that your connection is secure. If there isn’t a lock, the site is likely to be suspicious.
Here are some of the tips that might be useful to prevent yourself from being a victim of pharming.
A combination of malware protection and adherence to the latest cybersecurity best practices is the most effective method of protecting yourself from cybercrimes such as pharming.

Digital security is becoming an increasingly important concern in today's world. With the rise of digital transformation, there is an ever-increasing amount of personal and sensitive data being shared online. In the past, centralized entities such as governments, banks, and corporations have been responsible for managing and protecting this data. However, with the advent of decentralized identity, the role of these centralized entities is changing.
In today's digital age, data leaks have become a significant threat to individuals and businesses alike. Data leaks refer to the accidental or intentional disclosure of sensitive information to unauthorised parties. Such information can include personal information, financial data, trade secrets, and intellectual property amongst other things.
